Maryland Home Improvement Contractor (MHIC) Exam — Questions and Answers

Question 1: A contractor fails to include the required cancellation notice in a home solicitation sales contract in Maryland. What is the legal consequence?

The contractor faces a $50 fine per occurrence
The MHIC may suspend the contractor's license for 30 days
The buyer's right to cancel is extended until proper notice is provided (Correct answer)
The contract is automatically void and unenforceable from the start

Correct answer: The buyer's right to cancel is extended until proper notice is provided

If a contractor fails to include the required written notice of cancellation rights, the buyer's right to cancel is extended — they may cancel at any time until proper notice is given, even months or years later. This strong remedy incentivizes contractors to comply.

Question 2: When framing an interior load-bearing wall, which minimum lumber grade is typically required by the IRC for studs used in walls up to 10 feet in height?

No. 1 Douglas Fir only
Select Structural grade only
No. 3 grade or better
Stud grade or better (Correct answer)

Correct answer: Stud grade or better

The IRC specifies that studs used in load-bearing walls must be 'Stud' grade or better (which includes No. 1, No. 2, and Select Structural). Stud-grade lumber is specifically designed and graded for vertical applications in wall framing, providing the required strength and stiffness for walls up to 10 feet tall.

Question 3: A homeowner wants to add a second-story addition to a load-bearing wall. The contractor must install a header over a new 8-foot rough opening. Using engineered lumber, which header option provides the greatest span capacity while minimizing deflection?

A doubled 2×8 with metal connector plates at both bearing ends
Two 2×10 dimensional lumber members nailed together with a 1/2-inch plywood spacer
A laminated veneer lumber (LVL) header engineered to the specific load conditions (Correct answer)
A glulam (glued laminated timber) beam sized to the span table specifications

Correct answer: A laminated veneer lumber (LVL) header engineered to the specific load conditions

LVL (Laminated Veneer Lumber) is an engineered wood product manufactured with consistent grain orientation and adhesive bonding, giving it superior strength-to-size ratios and predictable deflection characteristics compared to sawn lumber or basic glulam for residential headers. For a load-bearing wall with a second story above, LVL engineered specifically to the load conditions provides the most reliable and code-compliant solution.

Question 4: A 'punch list' in construction project management is:

A log of OSHA safety violations recorded during the project
The original scope of work described in the signed contract
A list of remaining deficiencies or incomplete items to be corrected before final acceptance (Correct answer)
The list of subcontractors scheduled to be paid at project completion

Correct answer: A list of remaining deficiencies or incomplete items to be corrected before final acceptance

A punch list is a document created near project completion listing items that do not conform to contract specifications or that remain incomplete. The contractor must address all punch list items before the owner grants final acceptance and releases final payment.

Question 5: When is an MHIC license applicant exempt from taking the Home Improvement Law and Regulations exam?

Once
Sometimes
Always
Never (Correct answer)

Correct answer: Never

The Maryland Home Improvement Commission (MHIC) requires all applicants for a home improvement contractor license to pass the Home Improvement Law and Regulations exam. There are no exemptions from this exam, as it ensures all licensees possess a fundamental understanding of the legal framework governing home improvement work in Maryland. This requirement is crucial for protecting consumers and maintaining professional standards within the industry.

Question 6: A contractor is installing fiber-cement lap siding on a home in a coastal HVHZ (High Velocity Hurricane Zone). The manufacturer's installation instructions specify 6d corrosion-resistant nails with a minimum 1½" penetration into studs at 16" o.c. The local AHJ requires HVHZ wind uplift compliance per FBC. Which fastening modification is MOST likely required above the manufacturer's standard spec?

Adhesive back-bedding in addition to nailing at every stud bay
No modification needed — manufacturer specs always supersede local codes in HVHZ
Longer nails (10d) to increase shear capacity against horizontal wind loads
Closer nail spacing (typically 6" o.c. or per the NOA), hot-dipped galvanized or stainless steel fasteners, and nailing into blocking at panel edges (Correct answer)

Correct answer: Closer nail spacing (typically 6" o.c. or per the NOA), hot-dipped galvanized or stainless steel fasteners, and nailing into blocking at panel edges

In HVHZ jurisdictions (primarily South Florida under FBC), all cladding products must be installed per an approved Notice of Acceptance (NOA) rather than just the manufacturer's standard national installation guide. NOA requirements typically mandate tighter fastener spacing (often 6" o.c. along studs or at panel edges), specific corrosion-resistant fastener grades (316 stainless in salt-air environments), and blocking at horizontal joints. Longer nails address embedment depth, not spacing; adhesive is not an approved primary fastener substitute; and manufacturer specs do NOT supersede local code — the more restrictive standard always controls.

Question 7: A contractor is selecting concrete for a basement floor slab that will be exposed to freeze-thaw cycles and deicing salts. Which concrete specification is most critical for durability in this application?

High slump (8+ inches) for easy placement
High water-cement ratio for extended workability
Lightweight aggregate concrete to reduce dead load
Air-entrained concrete with low water-cement ratio (Correct answer)

Correct answer: Air-entrained concrete with low water-cement ratio

Air-entrained concrete with a low water-cement ratio is essential for freeze-thaw durability. Air entrainment creates microscopic bubbles that relieve pressure as water expands when freezing. A low water-cement ratio increases strength and reduces permeability. High slump and high water-cement ratios both weaken concrete and reduce durability.

Question 8: A Maryland home improvement contractor completes a $14,500 job and the homeowner pays in full. Three weeks later, the homeowner discovers the contractor never pulled a required permit. Under Maryland law, which of the following is the most accurate statement regarding the contractor's liability?

The contractor's liability is extinguished once the homeowner accepts the completed work and pays in full.
The contractor may face license suspension and must remedy the permit violation at no additional cost to the homeowner, even though payment was accepted. (Correct answer)
The contractor can charge the homeowner for the cost of retroactively obtaining the permit since it was an oversight.
The homeowner forfeits any remedy because they accepted the work without verifying the permit was pulled.

Correct answer: The contractor may face license suspension and must remedy the permit violation at no additional cost to the homeowner, even though payment was accepted.

Under Maryland's Home Improvement Law, failure to obtain required permits is a violation regardless of whether the homeowner has paid or accepted the work. The contractor remains responsible for permit compliance and can face MHIC disciplinary action including suspension. Acceptance of payment does not extinguish the contractor's regulatory obligations or liability for the violation.

Question 9: A MHIC contractor is underpinning a century-old rubble stone foundation using helical piers. After installation, the structural engineer's report notes that two piers achieved target torque at 12 feet depth, while three adjacent piers hit refusal at 6 feet on an obstruction and were terminated. The engineer accepts the early-termination piers based on torque correlation alone. Six months later, differential settlement resumes. What is the most likely cause that the torque-correlation acceptance was insufficient to catch?

The helical plate diameter was undersized for the load transferred from the rubble stone wall, causing plate punching failure over time
Vibration from nearby traffic caused the helical flights to unscrew from the shaft connections at the obstruction depth
The obstructions at 6 feet were large boulders or construction debris within fill, and the piers bear on the obstruction rather than competent native soil, providing only temporary support as the obstruction shifts or voids exist beneath it (Correct answer)
Helical pier corrosion accelerated by the groundwater table intersecting the pier shafts at 6 feet

Correct answer: The obstructions at 6 feet were large boulders or construction debris within fill, and the piers bear on the obstruction rather than competent native soil, providing only temporary support as the obstruction shifts or voids exist beneath it

Torque correlation (the relationship between installation torque and bearing capacity) is valid only when the pier bears on competent, native load-bearing stratum. When a pier hits refusal on a boulder, a concrete fragment from prior construction, or other debris within fill material, the torque readings can meet or exceed the target — falsely suggesting adequate bearing capacity. However, the pier is actually bearing on an isolated obstruction 'floating' within weak fill. As loads are applied over time, the boulder can shift, rotate, or the voids beneath it consolidate, causing the pier to lose its bearing point and settle. This is a well-documented failure mode in urban underpinning projects with mixed fill histories. The other options describe real but far less likely failure mechanisms that would not explain the pattern of three adjacent piers all showing early refusal followed by uniform resettlement.

Question 10: A homeowner wants to add a bedroom in an existing basement. Under most building codes, which of the following is the PRIMARY requirement that makes the space legally habitable?

The basement must be fully insulated to R-15 on all walls
Each bedroom must have an egress window meeting minimum size and sill height requirements (Correct answer)
The basement must have a sump pump installed
A smoke detector must be installed within 10 feet of the furnace

Correct answer: Each bedroom must have an egress window meeting minimum size and sill height requirements

An egress window is the primary code requirement for a basement bedroom to be considered habitable and safe. It provides an emergency exit in case of fire. Egress windows must meet specific minimum opening dimensions, sill height from the floor (max 44 inches), and net clear opening requirements.

Question 11: A change order increases the contract price by $3,000. Under Maryland Home Improvement Law, what is required for the change order to be valid?

Only the contractor's signature is needed
The change order must be approved by MHIC
An oral agreement is sufficient for changes under $5,000
It must be in writing and signed by both parties (Correct answer)

Correct answer: It must be in writing and signed by both parties

Maryland Home Improvement Law requires all change orders to be in writing and signed by both the contractor and the homeowner. Oral change orders are not enforceable.

Question 12: What is the primary purpose of the Maryland Home Improvement Guaranty Fund?

To cover permit fees for low-income homeowners
To compensate homeowners harmed by licensed contractors who cannot pay judgments (Correct answer)
To reimburse contractors for unpaid work
To fund contractor training programs

Correct answer: To compensate homeowners harmed by licensed contractors who cannot pay judgments

The Guaranty Fund provides a financial safety net for homeowners who obtain a judgment against a contractor that is unable to pay.

Question 13: A Maryland contractor wants to upgrade from a salesperson license to a full contractor license. What additional education may be required?

Submit three letters of recommendation
Complete a 10-hour OSHA course
Only pay the difference in licensing fees
Demonstrate additional field experience and pass the contractor examination (Correct answer)

Correct answer: Demonstrate additional field experience and pass the contractor examination

Upgrading from salesperson to contractor license typically requires meeting additional experience requirements and passing the contractor-level examination.

Question 14: Builder's risk insurance is specifically designed to cover:

Injuries sustained by workers during construction
The contractor's liability for defective workmanship discovered after project completion
Physical damage to the structure and materials while the project is under construction (Correct answer)
Loss of business income if the contractor is unable to work due to illness

Correct answer: Physical damage to the structure and materials while the project is under construction

Builder's risk (also called 'course of construction') insurance covers physical damage to a building and its materials during the active construction period, including losses from fire, wind, theft, or vandalism before the project is complete and handed over to the owner.

Question 15: A homeowner cancels a home improvement contract within 3 business days of signing. Under Maryland law, what must the contractor do?

Require the homeowner to pay for any materials already ordered
Charge a 10% cancellation fee before refunding
Refund all payments made by the homeowner within 10 days (Correct answer)
Keep any deposit already paid as liquidated damages

Correct answer: Refund all payments made by the homeowner within 10 days

Maryland's right of rescission gives homeowners 3 business days to cancel a home improvement contract. Upon cancellation, the contractor must refund all payments within 10 days.

Question 16: Which format of continuing education is most likely to be accepted by MHIC for license renewal?

Attending a county zoning board meeting and submitting a summary
Self-study using any published textbook on construction
Online or in-person courses from Commission-approved providers with documented completion certificates (Correct answer)
Informal mentorship from a senior contractor with no paperwork

Correct answer: Online or in-person courses from Commission-approved providers with documented completion certificates

MHIC accepts continuing education only from approved providers with verifiable documentation of course completion.

Question 17: Under MHIC regulations, what information must appear on a home improvement contractor's vehicle used for business?

The contractor's personal home address
Only the business name is required
The contractor's MHIC license number and business name (Correct answer)
No markings are required on vehicles

Correct answer: The contractor's MHIC license number and business name

Maryland MHIC regulations require that vehicles used in connection with home improvement work display the contractor's business name and MHIC license number.

Question 18: An MHIC licensee's license has been placed on inactive status. A friend asks the licensee to oversee a $3,000 bathroom renovation at the friend's home, agreeing to pay the licensee a management fee. The licensee agrees but does not pull permits or sign contracts under their name. Which statement BEST describes the legal risk?

The licensee is permitted to act as a project manager without a license as long as they do not perform any physical labor themselves
Inactive MHIC licensees retain full contracting privileges for projects under $10,000 as a courtesy extension
There is no violation because the contract amount is under $5,000 and the licensee is acting in an advisory role only
The licensee may be subject to disciplinary action and criminal penalties for engaging in home improvement contracting with an inactive license (Correct answer)

Correct answer: The licensee may be subject to disciplinary action and criminal penalties for engaging in home improvement contracting with an inactive license

An inactive MHIC license does not authorize the holder to engage in home improvement contracting activity. Supervising, managing, or receiving compensation for a home improvement project — even indirectly — constitutes contracting under Maryland law. Violations can result in administrative penalties, license denial or revocation, and criminal charges under the Home Improvement Law.

Question 19: What is the maximum deposit a licensed MHIC contractor may collect from a homeowner before beginning work on a home improvement contract?

One-half (50%) of the total contract price
There is no legal deposit limit in Maryland
One-quarter (25%) of the total contract price
One-third (33⅓%) of the total contract price (Correct answer)

Correct answer: One-third (33⅓%) of the total contract price

Maryland law limits the initial deposit a home improvement contractor may collect to one-third (1/3) of the total contract price. Exceeding this limit is a violation of the MHIA and can result in disciplinary action.

Question 20: When a client requests additional work not included in the original contract scope, a contractor should:

Stop all work until an entirely new contract is negotiated
Absorb the cost if it is less than 10% of the original contract value
Obtain a signed change order documenting the scope and price before proceeding (Correct answer)
Perform the work as a goodwill gesture to maintain the client relationship

Correct answer: Obtain a signed change order documenting the scope and price before proceeding

Any change to the original contract scope must be documented in a written change order, signed by both parties, before the additional work begins. This protects the contractor's right to be paid for the extra work and prevents scope creep disputes.

Question 21: An individual seeking a Home Improvement contractors license was denied by the Home Improvement commission due to failure to provide the required financial information. Following a hearing the denial was reaffirmed. How longs must he wait before he may reapply for a license.

4 months
5 months
6 months (Correct answer)
7 months

Correct answer: 6 months

If an individual's application for a Home Improvement Contractor's license is denied by the MHIC and that denial is upheld after a hearing, there is a mandatory waiting period before reapplication. The applicant must wait 6 months from the date the denial was reaffirmed. This period allows time for the applicant to address the issues that led to the initial denial.

Question 22: According to the IRC stairway requirements, what is the maximum allowable rise (vertical height) for a single step in an interior staircase?

7¾ inches (Correct answer)
8¼ inches
7 inches
8 inches

Correct answer: 7¾ inches

The IRC specifies a maximum riser height of 7¾ inches for interior staircases. Additionally, the minimum tread depth is 10 inches. These dimensions are set to reduce the risk of falls on stairs, which are a leading cause of home injuries.

Question 23: MHI Solutions LLC holds an active MHIC license, with its president serving as the qualifying party. The president unexpectedly resigns. Under MHICL, what must the company do to remain in compliance?

Notify the Maryland Home Improvement Commission and designate a new qualifying party within 30 days to avoid license lapse (Correct answer)
Submit a change-of-officer form to the Maryland Department of Labor; the Commission is notified automatically
Continue operating normally until the license's annual renewal date, then update the qualifying party on the renewal application
Immediately cease all home improvement work until a new license is issued under a new qualifying party

Correct answer: Notify the Maryland Home Improvement Commission and designate a new qualifying party within 30 days to avoid license lapse

MHICL requires a licensed business entity to maintain a designated qualifying party — the individual licensee responsible for the company's compliance. When that person leaves, the company must promptly notify the Commission and provide a replacement qualifying party within the required window (30 days). Operating without a current qualifying party is a violation. The Commission does not receive automatic notifications from other state agencies; the licensee bears the duty to report the change directly.

Question 24: An MHIC contractor's home improvement contract includes a clause stating: 'Contractor shall not be liable for any delay caused by weather, supplier shortages, or any other cause beyond Contractor's direct control, and no penalty or price reduction shall apply.' Under Maryland consumer protection standards applicable to home improvement contracts, this clause is best characterized as:

Void and unenforceable only if the delay exceeds 90 days
Permissible as a standard force majeure provision, fully enforceable
Potentially unfair and deceptive if it waives the homeowner's right to damages for unreasonable delays within the contractor's control (Correct answer)
Required by MHIC regulations and cannot be removed from any contract

Correct answer: Potentially unfair and deceptive if it waives the homeowner's right to damages for unreasonable delays within the contractor's control

While legitimate force majeure clauses are generally enforceable, a broadly worded clause that sweeps in delays within the contractor's control — such as poor scheduling or subcontractor mismanagement — can constitute an unfair and deceptive trade practice under Maryland's Consumer Protection Act (CPA). Maryland courts have held that contract provisions that mislead consumers about their legal remedies violate the CPA. The clause's legality hinges on whether it improperly strips consumers of rights they would otherwise hold.

Question 25: What is a requirement of a home improvement contract in the following choices?

Before work starts, the customer receives a signed copy of the contract. (Correct answer)
The seller must reclaim it at his own expense within 20 days from the date of cancellation.
The cost of replacing substandard materials
When the property owner will do the house improvements.

Correct answer: Before work starts, the customer receives a signed copy of the contract.

A key requirement for home improvement contracts, designed to protect consumers, is that the customer must receive a signed copy of the contract before any work commences. This ensures transparency and provides the homeowner with a legal document outlining all agreed-upon terms, scope of work, costs, and timelines. It helps prevent misunderstandings and disputes by ensuring both parties have a clear record of their agreement.

Question 26: A contractor is installing fiberglass batt insulation in a 2×6 exterior wall cavity in Climate Zone 5. Which installation practice is critical to achieving the rated R-value of the insulation?

Compressing the batt slightly to fill the cavity completely without any voids
Splitting the batt lengthwise and staggering two thinner layers for better coverage
Applying a vapor retarder over the batt before closing with drywall, regardless of facing type
Installing the batt at full thickness without compression, with no gaps or voids (Correct answer)

Correct answer: Installing the batt at full thickness without compression, with no gaps or voids

Fiberglass batt insulation achieves its rated R-value only when installed at full, uncompressed thickness. Compression reduces the air pockets between fibers that provide thermal resistance — a batt compressed to fill a smaller cavity will have a lower effective R-value. Gaps and voids also create thermal bridges that significantly degrade performance.

Question 27: A homeowner signs a home improvement contract on a Saturday at a home show. On the following Monday evening (Day 3), she mails a written cancellation notice. The contractor argues the rescission is untimely. Under Maryland's three-day right of rescission rules, which analysis is correct?

The rescission is timely only if the contractor received the mailed notice by the end of Day 3, not merely if it was postmarked
The rescission is timely because Sundays are excluded from the three-business-day count under federal and Maryland law (Correct answer)
The rescission is untimely because the right of rescission does not apply to contracts signed at home shows, only at the homeowner's residence
The rescission is untimely because all calendar days, including Sunday, count toward the three-day period

Correct answer: The rescission is timely because Sundays are excluded from the three-business-day count under federal and Maryland law

Under both the Federal Trade Commission's Cooling-Off Rule and Maryland's corresponding provisions, the three-day rescission period counts only business days. Sundays (and federal holidays) are excluded. A contract signed Saturday gives the homeowner until the close of the third business day — Tuesday — to cancel. Mailing on Monday is timely. The right applies to sales made at locations other than the seller's permanent place of business, which includes home shows.

Question 28: In project scheduling, 'float' (also called 'slack') refers to:

The amount of time a task can be delayed without delaying the overall project completion date (Correct answer)
Contingency money held in reserve for cost overruns
The overlap period when two subcontractors work in the same area simultaneously
The difference between the original bid price and the actual project cost

Correct answer: The amount of time a task can be delayed without delaying the overall project completion date

Float (or slack) is the scheduling flexibility available to a non-critical task — the amount of time it can slip without pushing back the project's final completion date. Tasks on the critical path have zero float.

Question 29: A homeowner requests that a kitchen renovation contract include a clause that requires the contractor to use only materials from a specific brand. Is this permissible?

Only if the materials meet minimum code requirements
Yes, homeowners can specify material requirements in the contract (Correct answer)
No, contractors have sole discretion over materials used
Only if MHIC pre-approves the specified brand

Correct answer: Yes, homeowners can specify material requirements in the contract

Maryland home improvement contracts can include homeowner-specified material requirements. Contractors must honor contractual material specifications agreed upon by both parties.

Question 30: A deck ledger board is being attached to a house that has an exterior rigid foam insulation layer 2 inches thick behind the siding. Which of the following correctly describes the code-compliant fastening approach?

Attach the ledger with structural screws into the foam only, since modern rigid foam has adequate compressive strength
Install a spacer block between the ledger and the house equal in thickness to the foam and fasten through both
Use standard lag screws of sufficient length to account for the foam, fastening through the foam into the band joist
Remove the foam insulation and siding in the ledger attachment zone and attach the ledger directly to the band joist with proper flashing (Correct answer)

Correct answer: Remove the foam insulation and siding in the ledger attachment zone and attach the ledger directly to the band joist with proper flashing

IRC Section R507.9 and associated ledger attachment tables assume direct wood-to-wood contact. Attaching a ledger through compressible foam insulation is not permitted by prescriptive code because the foam can compress over time, reducing fastener clamping force and creating a potentially dangerous connection. The correct approach is to remove the foam in the ledger zone and attach directly to the band joist with proper flashing to maintain the weather barrier. Spacer blocks do not resolve the compressibility issue, and foam alone provides no structural fastening capacity.

Question 31: A homeowner wants to add a bathroom on a second floor above an existing unfinished basement. The contractor discovers the existing floor joists are 2×8 at 16" O.C. spanning 14 feet. Which concern is MOST critical to evaluate first?

Whether the existing joists can support the added wet area dead and live loads (Correct answer)
Whether the joist wood species is suitable for staining
Whether the basement ceiling height will be reduced
Whether permits were pulled for the original framing

Correct answer: Whether the existing joists can support the added wet area dead and live loads

Adding a bathroom introduces significant additional dead load (tile, cement board, fixtures) and live load. The existing 2×8 joists must be evaluated for their span capacity under the new combined loads before any work begins, as undersized joists can lead to excessive deflection or structural failure.

Question 32: Which of the following is NOT a required element of a written Maryland Home Improvement contract?

The approximate start and completion dates.
A mandatory binding arbitration clause. (Correct answer)
A description of the work to be performed and materials to be used.
The contractor's MHIC license number.

Correct answer: A mandatory binding arbitration clause.

While a contract can contain a mandatory arbitration clause, it is not a required element. If one is included, it must be clearly disclosed and initialed by both parties. The other items—approximate dates, the MHIC license number, and a clear scope of work—are all mandatory components of a valid contract.

Question 33: A Maryland MHIC licensee wants to advertise a special financing offer to homeowners. What must the advertisement comply with?

MHIC licensing rules only, since finance is not regulated
Federal Truth in Lending Act (Regulation Z) disclosure requirements (Correct answer)
Only local county advertising ordinances
Verbal disclosure requirements with no written documentation needed

Correct answer: Federal Truth in Lending Act (Regulation Z) disclosure requirements

Any contractor advertising financing must comply with the federal Truth in Lending Act (Regulation Z), which requires clear disclosure of APR and credit terms.

Question 34: Under Maryland law, within how many days must a contractor begin work after the contract start date, unless the contract specifies otherwise?

Within 10 days of signing
Within 30 days of signing
There is no statutory start deadline; the contract governs (Correct answer)
Within 7 days of permit issuance

Correct answer: There is no statutory start deadline; the contract governs

Maryland Home Improvement Law requires that contracts specify start and completion dates, and the contractual terms govern the timeline. There is no separate statutory override unless the contractor abandons the project.

Question 35: A contractor wants to advertise home improvement services in Maryland. Which statement about advertising is correct?

The MHIC license number must appear in all advertisements (Correct answer)
License numbers are only needed on written contracts
Only print ads require a license number
No license number is required in ads

Correct answer: The MHIC license number must appear in all advertisements

Maryland requires that an MHIC licensee include their license number in all advertisements for home improvement services.

Question 36: A contractor receives a $18,000 deposit from a new client for a project scheduled to start in five weeks. Facing cash-flow pressure, the contractor uses $14,000 of this deposit to pay outstanding invoices from a different, completed project. The contractor's business then fails before the new project begins. What MHIC violation has occurred?

No violation — MHIC regulations do not govern how contractors allocate deposit funds before project commencement
A violation only if the original contract did not include a clause permitting flexible use of advance payments
The contractor violated MHIC rules by using one client's deposit funds to satisfy financial obligations from a separate client's project (Correct answer)
A violation only if the contractor failed to repay the diverted funds within 30 days of the project start date

Correct answer: The contractor violated MHIC rules by using one client's deposit funds to satisfy financial obligations from a separate client's project

MHIC regulations prohibit contractors from commingling client funds or redirecting money received from one homeowner to cover costs or debts from another project. Deposits must be treated as restricted funds earmarked for the specific contract for which they were received. Using a new client's deposit to pay off old debts is a serious fiduciary violation that can result in license suspension or revocation, personal liability, and a Guaranty Fund claim by the harmed homeowner.

Question 37: A licensed MHIC contractor submits a bid that includes pulling all necessary permits. After winning the contract, the contractor discovers the local jurisdiction requires a homeowner co-signature on the permit application. The homeowner refuses to sign, claiming the contractor should handle everything. Which statement best reflects the contractor's legal and ethical obligations under MHIC standards?

The contractor must obtain the permit regardless of the homeowner's refusal by representing the homeowner as applicant without their signature
The contractor may begin work and apply for a retroactive permit after project completion to avoid delays
The contractor should halt work, explain to the homeowner that proceeding without a required permit violates Maryland law and could jeopardize the contractor's license, and seek resolution (Correct answer)
The contractor may proceed without the permit if the homeowner has refused to cooperate, documenting the refusal in writing

Correct answer: The contractor should halt work, explain to the homeowner that proceeding without a required permit violates Maryland law and could jeopardize the contractor's license, and seek resolution

Under Maryland Home Improvement Law and MHIC regulations, performing work that requires a permit without obtaining one is a violation that can result in license suspension or revocation. A contractor may not forge or misrepresent a homeowner's co-signature, and proceeding without a required permit—even with documented homeowner refusal—still exposes the contractor to disciplinary action. The correct course is to halt work, clearly explain the legal obligation to the homeowner, and work toward a lawful resolution before proceeding.

Question 38: During a kitchen remodel, a contractor discovers the existing floor joists are Douglas Fir No. 2, 2×10s, spaced 16" O.C. spanning 14 feet. The homeowner wants to add a 500-lb cast-iron soaking tub. Before proceeding, the contractor's FIRST obligation under MHIC standards is to:

Determine whether the existing framing meets the required live load capacity for the new use (Correct answer)
Immediately sister the joists with matching lumber before any other work continues
Notify the homeowner that the project cannot proceed without a structural engineer
Require the homeowner to obtain a load calculation stamp from the building department

Correct answer: Determine whether the existing framing meets the required live load capacity for the new use

The contractor's first obligation is to assess whether the existing structure can support the new load — not to automatically require engineering or immediately reinforce. A standard residential floor is designed for 40 psf live load; a filled cast-iron tub can exceed this significantly when concentrated. The contractor must evaluate the load and then determine the appropriate course of action (sistering, engineering referral, or confirming adequacy). Jumping directly to sistering without assessment or mandating engineer involvement before any analysis is premature and not the first required step.

Question 39: Under the IRC, when installing a wood-framed deck attached to a house, what is the required fastener for connecting the ledger board to the house rim joist to resist lateral (horizontal) forces?

Construction adhesive plus 10d nails at 6 inches on center
Approved lag screws or bolts with specified spacing (Correct answer)
Two 16d common nails per joist bay
Simpson Strong-Tie LUS joist hangers only

Correct answer: Approved lag screws or bolts with specified spacing

The IRC requires ledger boards to be attached with approved lag screws or through-bolts sized and spaced according to the deck load tables in the code. Simple nails are insufficient to resist the lateral and withdrawal forces placed on a deck ledger. The specific size and spacing depends on joist span and species of lumber per IRC Table R507.9.1.3(1).

Question 40: A Maryland roofing contractor is installing asphalt shingles on a 3:12 pitch roof in Baltimore County (IECC Climate Zone 4). Where exactly must the ice barrier (self-adhering polymer-modified bitumen) terminate at the eave end of the roof?

At a point 24 inches past the drip edge, measured along the roof deck
At a point 24 inches above the exterior edge of the exterior wall, measured along the roof slope
At a point 24 inches inside the interior face of the exterior wall, measured horizontally (Correct answer)
At the ridge if the roof pitch is below 4:12, since the entire roof deck is at risk

Correct answer: At a point 24 inches inside the interior face of the exterior wall, measured horizontally

IRC R905.2.7.1 requires the ice barrier to extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building — measured horizontally, not along the slope. This ensures the barrier covers the area directly above the heated wall below, where ice dams cause the most damage. Measuring along the slope (Answer A) is a common field error that may leave the critical wall-line area unprotected on steeper pitches.

Question 41: Why might MHIC require education specifically on Maryland's Home Improvement Law rather than general construction knowledge?

Because Maryland requires contractors to be licensed as attorneys
Because state-specific laws govern contracts, disclosures, and dispute resolution unique to Maryland consumers and contractors (Correct answer)
Because federal law mandates state-specific exams for all contractors
Because general construction education is not available in Maryland

Correct answer: Because state-specific laws govern contracts, disclosures, and dispute resolution unique to Maryland consumers and contractors

Maryland-specific education ensures contractors understand state laws that directly govern their contracts, consumer interactions, and legal obligations.

Question 42: A homeowner is installing an egress window in a below-grade bedroom. The finished window well extends 52 inches deep below grade. Under the IRC, what is the specific requirement triggered by this well depth?

The well must have a permanently affixed ladder or steps usable with the window in the fully open position (Correct answer)
A sump pump drain must be installed at the bottom of the well
A cover or grate rated for 750 lbs must be installed over the well
The well must be widened to a minimum of 48 inches to compensate for the depth

Correct answer: The well must have a permanently affixed ladder or steps usable with the window in the fully open position

IRC R310.2.3 requires that window wells with a vertical depth greater than 44 inches be equipped with a permanently affixed ladder or steps. At 52 inches deep, this well exceeds that threshold. The ladder must be usable with the window in the fully open position and must not encroach on the required clear opening dimensions of the window itself.

Question 43: A contractor is installing a load-bearing wall on the first floor of a two-story home. Which type of lumber grade is most appropriate for the structural studs in this wall?

Appearance grade (C Select)
Utility grade
Select Structural or No. 1 grade (Correct answer)
No. 3 grade or Construction grade

Correct answer: Select Structural or No. 1 grade

Load-bearing walls require lumber with high strength and minimal defects. Select Structural or No. 1 grade lumber meets the strength requirements for structural applications. Lower grades like No. 3 or Utility have more knots and defects that reduce load capacity and are not suitable for primary structural members.

Question 44: According to Maryland Home Improvement Law, what is the maximum deposit a contractor can accept from a homeowner before work begins?

50% of the contract price.
An amount agreed upon by both parties, not to exceed $5,000.
1/3 of the contract price. (Correct answer)
The total cost of materials needed for the project.

Correct answer: 1/3 of the contract price.

The Maryland Home Improvement Law explicitly states that a contractor cannot accept more than one-third (1/3) of the total contract price as a deposit before work commences. No payment can be accepted until the contract is signed by all parties.

Question 45: Which of the following is NOT a valid basis for filing a mechanic's lien in Maryland?

Lost profits from a contract that was cancelled before any work began (Correct answer)
Unpaid materials delivered to and incorporated into the property
Unpaid design services provided by a licensed architect for the project
Unpaid labor for construction work performed on the property

Correct answer: Lost profits from a contract that was cancelled before any work began

Maryland mechanic's liens can only be filed for labor actually performed or materials actually furnished and incorporated into the property. Lost profits on a cancelled contract where no work was performed do not create lien rights.

Question 46: During a bathroom remodel, a contractor relocates the toilet 4 inches farther from the existing drain stack, requiring an extended horizontal drain run. The drain is 3 inches in diameter and runs horizontally 8 feet before connecting to a 4-inch vertical stack. What is the minimum slope required for the horizontal drain run, and what is the maximum length permitted before a cleanout is mandatory?

Minimum 1/8 inch per foot slope; a cleanout is required at every change of direction exceeding 45 degrees
Minimum 1/4 inch per foot slope; a cleanout is required at the upper terminal of the horizontal run exceeding 5 feet (Correct answer)
Minimum 1/4 inch per foot slope; cleanout required when the horizontal run exceeds 100 feet
Minimum 1/8 inch per foot slope; cleanout required at 50-foot intervals

Correct answer: Minimum 1/4 inch per foot slope; a cleanout is required at the upper terminal of the horizontal run exceeding 5 feet

Per IRC Section P3005.3, horizontal drains 3 inches and smaller require a minimum slope of 1/4 inch per foot (4-inch and larger drains permit 1/8 inch per foot). IRC Section P3005.2.6 requires a cleanout at the upper terminal of each horizontal drain run that is more than 5 feet in length. At 8 feet, this run triggers the upper-terminal cleanout requirement. The 100-foot cleanout interval applies to longer runs as an additional requirement, not a substitute for the upper-terminal rule.

Question 47: A homeowner in Maryland wants to add a detached garage with living space above it. Under MHIC contractor obligations, which code governs the fire separation requirements between the garage and the living unit above?

IFC Chapter 5 — General Building Limitations
NFPA 13 Sprinkler Standard
IRC Section R302 — Fire-Resistant Construction (Correct answer)
ANSI/ASHRAE Standard 90.1

Correct answer: IRC Section R302 — Fire-Resistant Construction

IRC Section R302 governs fire-resistant construction requirements for residential structures, including the separation requirements between garages and adjacent living spaces. It requires at minimum 5/8-inch Type X gypsum board on the garage side of a wall or ceiling that separates a garage from a dwelling unit or habitable room above.

Question 48: Experiencing in construction required by the MHIC. Can he still apply?

No
Yes (Correct answer)

Correct answer: Yes

To apply for a Maryland Home Improvement Contractor (MHIC) license, an individual must meet specific experience requirements. If the applicant has the necessary construction experience, they are eligible to proceed with the application process. The question implies the applicant possesses the required experience, making them eligible to apply.

Question 49: A homeowner wants to add a bedroom in their basement. Which of the following is a code requirement that specifically applies to basement sleeping rooms but NOT necessarily to other basement rooms?

Minimum 7-foot ceiling height
Smoke detector on the ceiling
GFCI-protected outlets
Egress window with minimum net clear opening (Correct answer)

Correct answer: Egress window with minimum net clear opening

Sleeping rooms (bedrooms) in basements require an egress window with a minimum net clear opening of 5.7 square feet (or 5.0 sq ft at grade level), a minimum opening height of 24 inches, and minimum opening width of 20 inches. This egress requirement is specific to sleeping rooms to allow escape in emergencies.

Question 50: Under Maryland Home Improvement Law, which of the following MUST be included in every home improvement contract?

A breakdown of the contractor's profit margin
The contractor's MHIC license number (Correct answer)
A list of all subcontractors to be used
The homeowner's credit score

Correct answer: The contractor's MHIC license number

Every Maryland home improvement contract must include the contractor's MHIC license number. This is a mandatory disclosure requirement under Maryland law.

Question 51: What is an EIN?

Installing a fence
Privacy Number.
Employer Identification (Correct answer)
2 Years

Correct answer: Employer Identification

An EIN stands for Employer Identification Number, a unique nine-digit number assigned by the IRS to identify a business entity for tax purposes. It functions similarly to a Social Security Number but for businesses. The other options—installing a fence, 2 years, and Privacy Number—have no connection to this tax-related acronym.

Question 52: Under OSHA's Hazard Communication Standard (HazCom), what must contractors maintain on-site for all hazardous chemicals used?

Annual chemical disposal logs
A written chemical inventory filed with the state
Purchase receipts and supplier invoices
Safety Data Sheets (SDS) accessible to all workers (Correct answer)

Correct answer: Safety Data Sheets (SDS) accessible to all workers

OSHA's HazCom Standard requires Safety Data Sheets for every hazardous chemical on site, accessible to workers at all times during each work shift.

Question 53: A contractor's MHIC license has been expired for 14 months. When she applies for reinstatement, the Commission reviews her continuing education record. Which scenario most accurately reflects the MHIC's position on CE compliance for reinstatement?

She is granted a 90-day grace period after reinstatement to complete any outstanding CE hours
She must complete the full 5-hour CE requirement before reinstatement is granted, regardless of what was completed before expiration (Correct answer)
Because she let the license lapse, she is permanently exempt from CE for the first renewal cycle after reinstatement
CE hours completed during the expired period can count toward reinstatement if they were from an approved provider

Correct answer: She must complete the full 5-hour CE requirement before reinstatement is granted, regardless of what was completed before expiration

When reinstating an expired MHIC license, the Commission requires that continuing education requirements be satisfied as a condition of reinstatement itself — not after the fact. Hours taken while the license was lapsed in an unrecognized status do not automatically satisfy the renewal-period requirement. The applicant must demonstrate compliance before the license is restored.

Question 54: A contractor uses a Gantt chart to plan a kitchen renovation. What does a Gantt chart primarily display?

The square footage breakdown of each work area
The budget allocation for each phase of work
The sequence and duration of project tasks over a timeline (Correct answer)
The organizational hierarchy of workers on the job

Correct answer: The sequence and duration of project tasks over a timeline

A Gantt chart is a horizontal bar chart that displays project tasks along a timeline, showing each task's start date, duration, and end date. It allows a contractor to visualize the entire project schedule at a glance.

Question 55: A homeowner pays a $6,000 deposit to an MHIC-licensed contractor before work begins. The contractor completes 40% of the project and then abandons it. The homeowner's actual unrecovered loss — after accounting for the value of work performed — is $4,200. The contractor's MHIC license lapses two months later. How does the license lapse affect the homeowner's Guaranty Fund claim?

The claim is barred because the contractor must hold an active license at the time the Fund claim is filed
The lapse reduces the maximum Fund recovery by 50% as a penalty for the homeowner's failure to verify current license status before filing
A lapsed license converts the claim to a criminal referral only; civil Fund recovery is no longer available
The homeowner may still file a valid claim because the contractor was licensed at the time the contract was executed and the harm occurred (Correct answer)

Correct answer: The homeowner may still file a valid claim because the contractor was licensed at the time the contract was executed and the harm occurred

Maryland's Guaranty Fund protects consumers harmed by MHIC licensees. The controlling factor is whether the contractor was licensed when the contract was formed and when the violation occurred — not whether the license remains active at the time the consumer files the claim. A subsequent lapse does not retroactively extinguish a valid consumer claim that arose during the licensed period.

Question 56: Under the Maryland Home Improvement Act, a written contract is required when the total price of a home improvement project is:

$100 or more
$500 or more (Correct answer)
$5,000 or more
$1,000 or more

Correct answer: $500 or more

Maryland law requires a written contract for any home improvement project where the total price — labor plus materials — is $500 or more. Below this threshold, an oral agreement may suffice, but a written contract is always recommended for consumer protection.

Question 57: What type of home improvement are there in Maryland?

Speaker and Conductor
Contractor and salesperson (Correct answer)
Conductor alone
Salesperson and Conductor

Correct answer: Contractor and salesperson

The Maryland Home Improvement Commission (MHIC) issues two primary types of licenses for individuals involved in home improvement work: the Contractor license, for those who perform or arrange for the work, and the Salesperson license, for those who solicit or negotiate contracts. These two categories cover the main roles regulated by the MHIC, ensuring proper oversight for both direct service providers and those involved in sales.

Question 58: If the contractor fails to re-pay the commission within _________________, the Commission may sue for nonpayment.

30 days (Correct answer)
15 days
1 year
6 months

Correct answer: 30 days

When the Home Improvement Guaranty Fund pays a claim to a homeowner, the responsible contractor is legally obligated to reimburse the fund. If the contractor fails to repay the Commission within a specified period, typically 30 days, the Commission has the authority to initiate legal action to recover the funds, ensuring the fund's integrity.

Question 59: In cold-weather masonry construction (ambient temperature below 40°F and falling), ASTM C1072 and standard industry practice require that freshly laid masonry be protected from freezing for a minimum of how long after placement?

24 hours
48 hours (Correct answer)
72 hours
12 hours

Correct answer: 48 hours

ASTM and the Masonry Standards Joint Committee (MSJC) cold-weather construction guidelines require that newly laid masonry be protected from freezing temperatures for a minimum of 48 hours after placement when ambient temperatures are below 40°F and falling. During this period, mortar must maintain a minimum temperature of 40°F to achieve initial set and gain sufficient strength to resist freeze damage. 24 hours is insufficient for mortar to develop the strength needed to withstand a freeze cycle without disruption to the bond.

Question 60: When scheduling subcontractors for a bathroom renovation, which sequence correctly reflects standard construction order?

Painting → Tile installation → Plumbing rough-in → Drywall
Tile installation → Drywall → Plumbing rough-in → Painting
Plumbing rough-in → Electrical rough-in → Drywall → Tile → Painting (Correct answer)
Drywall → Plumbing rough-in → Tile installation → Electrical rough-in

Correct answer: Plumbing rough-in → Electrical rough-in → Drywall → Tile → Painting

Rough-in work (plumbing and electrical) must be completed and inspected before walls are closed with drywall. Finish work — tile, then painting — comes last. Reversing this order forces costly tear-outs to access hidden systems.

Question 61: Which fund compensates Maryland homeowners harmed by licensed home improvement contractors who fail to complete work or perform defective work?

The MHIC Escrow Reserve Account
The Contractor Surety Bond Pool
The Home Improvement Guaranty Fund (Correct answer)
The Maryland General Treasury

Correct answer: The Home Improvement Guaranty Fund

The Home Improvement Guaranty Fund provides compensation to consumers damaged by licensed MHIC contractors.

Question 62: What is the required minimum number of air changes per hour when applying solvent-based coatings indoors under OSHA ventilation standards?

10 air changes per hour (Correct answer)
2 air changes per hour
Ventilation is only required when fumes are visible
6 air changes per hour

Correct answer: 10 air changes per hour

OSHA requires at least 10 air changes per hour when spray-applying solvent-based coatings in enclosed spaces to prevent flammable vapor accumulation.

Question 63: An MHIC-licensed contractor wants to operate under a trade name different from their legal business name. What must they do in Maryland?

Have the homeowner acknowledge the trade name in each contract
Register the trade name with the Maryland Department of Assessments and Taxation and update their MHIC records (Correct answer)
Obtain a separate MHIC license under the trade name
Simply use the trade name without any registration

Correct answer: Register the trade name with the Maryland Department of Assessments and Taxation and update their MHIC records

Trade names (also called 'doing business as' or DBA names) must be registered with the Maryland Department of Assessments and Taxation, and the MHIC records should reflect all names under which the contractor operates.

Question 64: A contractor is hired to build a deck attached to a house. Under the IRC, what is the maximum allowable height of a deck above grade before a guardrail is required?

30 inches (Correct answer)
24 inches
36 inches
18 inches

Correct answer: 30 inches

The IRC requires guardrails on decks and open-sided walking surfaces that are more than 30 inches above the floor or grade below. If a deck surface is 30 inches or less above grade, a guardrail is not mandated by code, though local jurisdictions may have stricter rules.

Question 65: Which Maryland agency enforces occupational safety and health regulations for workers in the construction industry?

Maryland Department of Labor, Licensing and Regulation
Maryland Home Improvement Commission
Maryland Department of the Environment
Maryland Occupational Safety and Health (MOSH) (Correct answer)

Correct answer: Maryland Occupational Safety and Health (MOSH)

Maryland Occupational Safety and Health (MOSH) is the state agency responsible for enforcing workplace safety and health regulations, including those applicable to construction workers.

Question 66: An MHIC contractor provides a warranty on their home improvement work. Under Maryland law, what is the minimum warranty period for most home improvement work?

2 years from date of completion
90 days from date of completion
1 year from date of completion
Maryland law does not set a specific minimum warranty period; the contract governs (Correct answer)

Correct answer: Maryland law does not set a specific minimum warranty period; the contract governs

Maryland Home Improvement Law does not mandate a specific minimum warranty period for general home improvement work. The warranty terms are negotiated and set forth in the contract.

Question 67: A contractor is pouring a concrete slab on grade in cold weather (ambient temperature 35°F). Which of the following practices is MOST important to prevent freeze damage to the fresh concrete?

Increase the water-to-cement ratio to generate more heat of hydration
Pour the slab at night to take advantage of cooler, more stable temperatures
Use accelerating admixtures and maintain the concrete temperature above 50°F during curing (Correct answer)
Add extra water to the mix to keep the concrete workable longer

Correct answer: Use accelerating admixtures and maintain the concrete temperature above 50°F during curing

In cold weather concreting, accelerating admixtures (such as calcium chloride in non-reinforced slabs) help speed up strength gain, and maintaining concrete temperature above 50°F (per ACI 306) ensures proper hydration and prevents freezing before the concrete achieves adequate strength. Adding water or increasing the water-to-cement ratio actually weakens the mix and should never be done.

Question 68: A homeowner pays a contractor $3,500 upfront before any work begins. Under MHIC regulations, is this deposit permissible?

No, deposits cannot exceed one-third of the contract price (Correct answer)
No, no deposit may be collected before work begins
Yes, any deposit amount is legal if the homeowner agrees
Yes, up to $5,000 may be collected before work starts

Correct answer: No, deposits cannot exceed one-third of the contract price

Maryland law limits initial deposits to one-third of the total contract price to protect consumers.

Question 69: Maryland law requires a home improvement contract to be in writing when the contract price exceeds:

$500 (Correct answer)
$2,500
$100
$5,000

Correct answer: $500

Any home improvement contract exceeding $500 must be in writing under the Maryland Home Improvement Law to ensure consumer protection and enforceability.

Question 70: An education provider receives Commission approval to offer MHIC continuing education in March. The Commission revokes that provider's approval in October of the same year due to non-compliance. A contractor completed a 3-hour course with that provider in August. How are those hours treated?

The hours are fully credited because the provider was approved at the time the course was completed. (Correct answer)
The hours are invalidated retroactively because the provider ultimately lost approval during the same year.
The hours are credited for half their value (1.5 hours) under the Commission's pro-rata rule for revoked providers.
The hours are credited only if the contractor can show he did not know about the pending revocation.

Correct answer: The hours are fully credited because the provider was approved at the time the course was completed.

Continuing education credits are evaluated based on the provider's approval status at the time the course was delivered, not at the time of license renewal. Because the provider held valid Commission approval in August when the contractor completed the course, those 3 hours remain valid and are fully credited.

Question 71: A contractor is framing an exterior wall that will serve as a bearing wall for a second floor. The plans specify doubled 2×10 headers over a 6-foot rough opening. The contractor has 2×10 lumber on site but also has LVL (laminated veneer lumber) members of the same depth. Which statement is most accurate regarding the substitution of LVL for dimensional lumber in this header application?

LVL is an approved substitute only if the span is under 4 feet
LVL substitution requires engineer of record approval and must match the original engineered design values to avoid over-spanning (Correct answer)
LVL may be substituted at a reduced section size since it has higher allowable bending stress than dimensional lumber
LVL cannot be used in exterior applications because it is not moisture-resistant

Correct answer: LVL substitution requires engineer of record approval and must match the original engineered design values to avoid over-spanning

LVL has higher bending strength (Fb) than dimensional lumber, which might suggest it can span further or be downsized. However, substituting any engineered lumber product for plan-specified dimensional lumber in a structural application requires approval from the engineer of record, because the original header design was calculated using specific material properties, deflection limits, and load paths. Unauthorized substitution — even with a 'stronger' material — can affect connection design, bearing length requirements, and code compliance. LVL is moisture-resistant when properly manufactured and sealed, making answer B incorrect. There is no 4-foot span restriction on LVL use.

Question 72: When constructing a concrete slab on grade, what is the PRIMARY purpose of placing a vapor barrier (polyethylene sheeting) beneath the slab?

To prevent ground moisture from migrating up through the concrete (Correct answer)
To prevent frost heave from damaging the slab
To reduce heat loss through the slab
To improve the bond between the subbase and concrete

Correct answer: To prevent ground moisture from migrating up through the concrete

A vapor barrier beneath a concrete slab-on-grade is installed to block capillary moisture migration from the soil up into the concrete and finished flooring above. Without it, moisture can cause efflorescence, deteriorate flooring adhesives, and promote mold growth. It does not address frost heave, thermal insulation, or bonding.

Question 73: A contractor is installing rigid foam insulation on the exterior of a wood-framed wall (continuous insulation). What is the MOST important consideration when determining the foam thickness?

Keeping the wall's dew point within the foam layer to prevent condensation on the sheathing (Correct answer)
Ensuring the foam is thick enough to provide a 1-hour fire rating
Matching the foam R-value exactly to the batt insulation inside the cavity
The color and UV resistance of the foam board facing

Correct answer: Keeping the wall's dew point within the foam layer to prevent condensation on the sheathing

In cold climates, if the continuous exterior foam is too thin, the sheathing temperature can drop below the dew point, causing moisture to condense on or within the sheathing and leading to rot and mold. The foam thickness must be sufficient (based on climate zone) to keep the sheathing warm enough to stay above the dew point of interior air that may diffuse through the wall.

Question 74: A home improvement contractor in Maryland wants to accept credit card payments. Which of the following applies?

They may accept credit cards but must comply with applicable payment processing laws and disclose any surcharges (Correct answer)
MHIC must approve any payment processor used
Credit card payments are prohibited for home improvement contracts
Credit card payments are only allowed for amounts under $1,000

Correct answer: They may accept credit cards but must comply with applicable payment processing laws and disclose any surcharges

Maryland contractors may accept credit card payments. However, they must comply with payment processing regulations, including proper disclosure if a surcharge is added for credit card use.

Question 75: How often must a Maryland home improvement contractor renew their MHIC license?

Every five years
Every three years
Every year
Every two years (Correct answer)

Correct answer: Every two years

MHIC licenses are renewed on a biennial (two-year) cycle. Contractors must submit renewal applications and fees before their license expires.

Question 76: A Maryland renovator is replacing window trim in a pre-1978 house. The homeowner provides a certified lead inspection report showing the specific window trim tested 'negative' for lead. The homeowner also signs a personal written waiver asking the contractor to skip all lead-safe work practices to save cost. Which statement is CORRECT under the EPA Lead RRP Rule?

Lead-safe practices are not required for the components documented as lead-free by a certified inspector, but the homeowner's personal waiver has no independent legal effect (Correct answer)
The waiver is valid because EPA's owner opt-out provision allows homeowners to waive RRP requirements in writing
The homeowner's signed waiver eliminates all RRP requirements for the project
Lead-safe practices are still required despite the negative test results because no homeowner waiver is ever recognized under federal law

Correct answer: Lead-safe practices are not required for the components documented as lead-free by a certified inspector, but the homeowner's personal waiver has no independent legal effect

Under the EPA RRP Rule, if a certified inspector or risk assessor has tested and found specific components to be lead-free, the renovator is not required to use lead-safe work practices on those particular components. However, the homeowner's personal waiver carries no independent legal weight — EPA eliminated the owner opt-out provision in a 2010 rule amendment. The valid exemption here is the certified component-specific test result, not the owner's signature. Choice D is also wrong because the negative test result does legitimately exempt those tested components.

Question 77: A Maryland contractor submits a written estimate before the homeowner signs the contract. The estimate lists labor and materials but omits both an approximate start date and an approximate completion date. The homeowner signs the estimate as the contract. Under Maryland Home Improvement Law, which of the following BEST describes the contract's status?

The contract is fully enforceable; start and completion dates are aspirational and not legally required elements in Maryland.
The contract satisfies Maryland law because estimates are held to a lower standard than formal contracts.
The contract is non-compliant because Maryland law specifically requires both an approximate start date and an approximate substantial completion date as mandatory written contract elements. (Correct answer)
The contract is voidable only if the homeowner can prove actual harm from the missing dates.

Correct answer: The contract is non-compliant because Maryland law specifically requires both an approximate start date and an approximate substantial completion date as mandatory written contract elements.

Maryland Home Improvement Law explicitly lists both an approximate start date and an approximate completion (or substantial completion) date as required elements of a written home improvement contract. Their omission makes the contract non-compliant regardless of whether harm results. This is one of the most frequently violated provisions in MHIC disciplinary cases—contractors often treat dates as informal and optional when Maryland law treats them as mandatory written disclosures. An estimate used as a contract is subject to exactly the same requirements as a formal contract.

Question 78: When installing a deck attached to a house in Maryland, which document typically governs the ledger board connection requirements?

NFPA 70 (National Electrical Code)
ANSI A117.1 accessibility standard
OSHA 1926 Subpart Q
IRC Section R507 and local amendments (Correct answer)

Correct answer: IRC Section R507 and local amendments

Attached deck construction, including ledger board connections, is governed by IRC Section R507 (Decks) along with any local Maryland amendments. The ledger connection is critical to prevent deck collapse and must meet specific fastener, flashing, and spacing requirements.

Question 79: Under Maryland's building code framework, when is a homeowner typically required to obtain a building permit before beginning work?

Only for additions that increase square footage by more than 400 sq ft
For any structural work, electrical work, plumbing, or project valued over a jurisdiction-defined threshold (Correct answer)
Only for projects that alter the exterior appearance of the home
Only when the project involves licensed subcontractors

Correct answer: For any structural work, electrical work, plumbing, or project valued over a jurisdiction-defined threshold

In Maryland and most jurisdictions, permits are required for structural work, electrical, plumbing, mechanical systems, and projects meeting or exceeding a value threshold set by the local jurisdiction. The scope of work — not just size or appearance — determines permit requirements.

Question 80: Which scheduling method identifies the longest sequence of dependent tasks that determines the minimum possible project completion time?

PERT analysis
Critical Path Method (CPM) (Correct answer)
Float time scheduling
Gantt chart analysis

Correct answer: Critical Path Method (CPM)

The Critical Path Method (CPM) identifies the longest chain of dependent tasks — the critical path — whose combined duration sets the earliest possible project completion date. Any delay on the critical path delays the entire project.
