National Home Inspector Examination (NHIE) - Certified Home Inspector — Questions and Answers
Question 1: What is the purpose of an arc-fault circuit interrupter (AFCI) breaker?
- To protect against ground faults in wet locations
- To limit current draw to 15 amps on all circuits
- To replace GFCI protection in bathrooms
- To detect dangerous arcing conditions that can cause fires (Correct answer)
Correct answer: To detect dangerous arcing conditions that can cause fires
AFCI breakers detect the electrical signature of arc faults—unintended arcing in wiring—and trip the circuit to prevent fires.
Question 2: A home inspector identifies open step flashing where a roof plane meets a sidewall. What is the primary risk of this deficiency?
- Water infiltration into the wall assembly and interior (Correct answer)
- Accelerated granule loss on adjacent shingles
- Premature oxidation of the roofing fasteners
- Reduced wind uplift resistance of the roof covering
Correct answer: Water infiltration into the wall assembly and interior
Open or improperly lapped step flashing creates a direct pathway for wind-driven rain to enter the wall-to-roof junction and damage sheathing, insulation, and interior finishes.
Question 3: A home inspector observes rust staining and corrosion on the exterior of a central air conditioner's refrigerant line set insulation. What does this MOST likely indicate?
- Normal weathering with no functional concern
- Pest damage from rodents nesting in the unit
- Condensation forming due to damaged or missing insulation (Correct answer)
- High refrigerant charge causing exterior frost
Correct answer: Condensation forming due to damaged or missing insulation
Rust and corrosion on line set insulation typically indicates that the insulation is compromised, allowing condensation to form on the cold suction line and cause moisture damage.
Question 4: Which financial metric is most useful for a buyer evaluating whether to request seller concessions based on inspection findings?
- Estimated cost-to-cure for identified defects (Correct answer)
- Debt-service coverage ratio
- Gross rent multiplier
- Capitalization rate
Correct answer: Estimated cost-to-cure for identified defects
The cost-to-cure figure represents the estimated expense to correct inspection deficiencies and directly informs concession negotiations.
Question 5: Which advertising claim is permissible and professionally appropriate for a Certified Home Inspector?
- 'Our inspections are 100% accurate and complete'
- 'We will find every defect in the home, guaranteed'
- 'State-certified inspector with over 500 completed inspections' (Correct answer)
- 'We guarantee you will never have a home problem after our inspection'
Correct answer: 'State-certified inspector with over 500 completed inspections'
Advertising verifiable credentials and experience counts is factual, honest, and professionally appropriate unlike performance guarantees that cannot be kept.
Question 6: When inspecting a service entrance, a home inspector notes the service drop conductors are less than 10 feet above a driveway. What is the concern?
- The conductors will corrode faster at lower heights
- A vehicle could contact the conductors, creating an electrocution hazard (Correct answer)
- The utility company will not connect service at this height
- The conductors may interfere with radio signals
Correct answer: A vehicle could contact the conductors, creating an electrocution hazard
The NEC requires service conductors to be at least 10 feet above driveways to prevent vehicles from contacting energized wires.
Question 7: A home inspector sees water stains on the ceiling below a second-floor bathroom. Which of the following is the FIRST area to investigate?
- The tub or shower drain collar and caulk lines (Correct answer)
- The wax ring seal at the toilet base
- The supply line shutoff valves
- The water heater anode rod
Correct answer: The tub or shower drain collar and caulk lines
Ceiling stains below a bath typically originate from tub or shower surround leaks at caulk lines or drain collars, which are the most common failure points.
Question 8: Which practice is considered unethical in home inspection marketing under ASHI and InterNACHI codes of ethics?
- Offering discounts to repeat clients
- Guaranteeing that a home is defect-free in advertising (Correct answer)
- Using client testimonials with their permission
- Advertising certifications and continuing education credentials
Correct answer: Guaranteeing that a home is defect-free in advertising
Guaranteeing a home is defect-free is misleading and impossible, violating professional codes of ethics that prohibit deceptive marketing claims.
Question 9: In Financial Analysis & Reporting, what is the FIRST step a CHI professional should take when encountering a new case or situation?
- Implement an immediate solution based on past experience
- Conduct a comprehensive assessment and gather all relevant information (Correct answer)
- Consult with a supervisor before taking any action
- Document the situation and wait for further instructions
Correct answer: Conduct a comprehensive assessment and gather all relevant information
In Financial Analysis & Reporting, a thorough initial assessment ensures all relevant factors are identified before deciding on an appropriate course of action. This systematic approach is fundamental to Certified Home Inspector practice.
Question 10: Which type of depreciation in real estate valuation is considered incurable?
- Deferred maintenance on exterior paint
- A leaking roof that requires immediate repair
- Functional obsolescence due to poor floor plan that cannot be economically corrected (Correct answer)
- Worn flooring that can be replaced at reasonable cost
Correct answer: Functional obsolescence due to poor floor plan that cannot be economically corrected
Incurable depreciation occurs when the cost to fix a deficiency exceeds the value it would add, making correction economically impractical.
Question 11: What documentation practice is considered essential in Market Analysis & Valuation within the Certified Home Inspector field?
- Completing all documentation at the end of the workday
- Only documenting unusual events or complications
- Recording actions, observations, and outcomes in real-time or as close to the event as possible (Correct answer)
- Using shorthand notes that can be expanded later if needed
Correct answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible
Real-time or near-real-time documentation in Market Analysis & Valuation ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.
Question 12: When inspecting a wood shake roof, which condition indicates an immediate safety and weathertightness concern?
- Shakes with varying widths from hand-splitting
- Silver-gray weathering coloration across the entire surface
- Missing, split, or severely cupped shakes exposing the underlayment or sheathing (Correct answer)
- Moss growth on the north-facing sections
Correct answer: Missing, split, or severely cupped shakes exposing the underlayment or sheathing
Missing or severely damaged shakes leave the underlayment or deck boards exposed, creating direct pathways for water infiltration and potentially indicating widespread end-of-life deterioration.
Question 13: During a home inspection, the inspector observes yellow or orange flames in a natural gas furnace burner. This indicates:
- High-efficiency combustion above 95% AFUE
- Normal flame color for a gas appliance
- Proper combustion with full fuel ignition
- Incomplete combustion possibly producing carbon monoxide (Correct answer)
Correct answer: Incomplete combustion possibly producing carbon monoxide
Yellow or orange flames in a gas burner indicate incomplete combustion, which can produce dangerous carbon monoxide; proper combustion produces a steady blue flame.
Question 14: A home inspector reviewing a property for valuation purposes notices deferred maintenance. How does this typically affect market value?
- It increases value by showing original features are intact
- It generally reduces market value due to anticipated repair costs (Correct answer)
- It only affects value if the inspector documents it formally
- It has no effect if the home is structurally sound
Correct answer: It generally reduces market value due to anticipated repair costs
Deferred maintenance signals future repair costs to buyers and appraisers, typically resulting in a downward adjustment to market value.
Question 15: Which condition in a crawlspace would MOST directly affect HVAC efficiency and indoor air quality?
- Vapor barrier installed with 6-inch overlaps
- Condensate drain line from the air handler draining to the crawlspace
- Insulation installed between floor joists above the crawlspace
- Open foundation vents with no vapor barrier and moisture on the ground (Correct answer)
Correct answer: Open foundation vents with no vapor barrier and moisture on the ground
Open vents with no vapor barrier allow moisture to enter the crawlspace, which can be drawn into the HVAC system through leaky ducts, reducing efficiency and introducing mold spores into conditioned air.
Question 16: Which practice best demonstrates a landlord's commitment to tenant retention through property maintenance?
- Implementing a preventive maintenance schedule and tracking all work orders (Correct answer)
- Deferring non-emergency repairs until lease renewal discussions
- Completing repairs only when legally required
- Allowing tenants to manage their own repairs for cost savings
Correct answer: Implementing a preventive maintenance schedule and tracking all work orders
A proactive preventive maintenance schedule reduces emergency repairs, extends property life, and demonstrates care for tenant comfort, improving retention.
Question 17: Which type of crack in a foundation wall is most concerning?
- Diagonal shrinkage crack
- Surface spalling
- Vertical hairline crack
- Horizontal structural crack (Correct answer)
Correct answer: Horizontal structural crack
While all foundation cracks warrant inspection, horizontal cracks are generally the most concerning. They often indicate significant external pressure on the foundation wall, such as from expansive soil or hydrostatic pressure, which can lead to bowing or structural failure. Vertical and diagonal shrinkage cracks are more common and often less severe, though still need monitoring.
Question 18: What is the standard voltage for most residential outlets in the US?
- 120 volts (Correct answer)
- 240 volts
- 110 volts
- 100 volts
Correct answer: 120 volts
In the United States, the standard voltage for most general-purpose residential outlets is 120 volts (V). This voltage powers common household appliances, lights, and electronics. Higher voltage (240V) circuits are typically reserved for large appliances like electric ranges, dryers, and central air conditioning units.
Question 19: Which location requires GFCI protection for receptacles under current NEC requirements?
- Bedroom circuits in homes built after 2000
- All 125-volt receptacles within 6 feet of a kitchen sink (Correct answer)
- Dedicated circuits for refrigerators
- Living room receptacles on exterior walls
Correct answer: All 125-volt receptacles within 6 feet of a kitchen sink
The NEC requires GFCI protection for receptacles within 6 feet of kitchen sinks to protect against shock from water contact.
Question 20: What does it mean when a home inspector finds an electrical panel with a 'used-by' rating of 100 amps but the service entrance conductors appear to be sized for 200 amps?
- This is an upgrade opportunity with no safety concern
- Conductor size does not affect panel ratings — only breaker size matters
- The utility company controls amperage delivery so oversized wires are harmless
- The oversized conductors could allow the utility to deliver more current than the panel is rated to handle safely (Correct answer)
Correct answer: The oversized conductors could allow the utility to deliver more current than the panel is rated to handle safely
If service conductors are larger than the panel's rating, the utility could deliver current exceeding the panel's safe capacity, which is a concern requiring evaluation.
Question 21: An inspector discovers that roof rafters are pulling away from the wall top plate. What is the most likely cause?
- Roof overloading from snow caused the ridge to deflect downward, rotating rafters off the plate
- Inadequate rafter-to-plate connections or missing hurricane ties allowing uplift forces to separate the joint (Correct answer)
- Thermal expansion of the roofing material is pulling the rafters upward
- The rafters were installed with the crown facing down, causing them to arch away from the plate
Correct answer: Inadequate rafter-to-plate connections or missing hurricane ties allowing uplift forces to separate the joint
Rafters pulling away from the top plate indicates that the toe-nail connection or metal connector was insufficient to resist wind uplift or rafter thrust.
Question 22: During a roof inspection, the home inspector observes black streaking running down the shingles. What is the most likely cause?
- Oil bleeding from the asphalt matrix
- Oxidation of the zinc strips at the ridge
- Chimney tar deposits washing down in rain
- Algae (Gloeocapsa magma) growth (Correct answer)
Correct answer: Algae (Gloeocapsa magma) growth
Dark streaks on asphalt shingles are almost always caused by Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in shingles and leaves a dark protective pigment.
Question 23: Which market trend would most likely cause residential property values to decline in a given area?
- Lower mortgage interest rates nationally
- An increase in local park and recreation improvements
- Construction of a new elementary school nearby
- A major employer in the area announcing a large facility closure (Correct answer)
Correct answer: A major employer in the area announcing a large facility closure
Major employer closures reduce local employment and population, decreasing housing demand and putting downward pressure on residential property values.
Question 24: What documentation practice is considered essential in Lease Negotiation & Terms within the Certified Home Inspector field?
- Completing all documentation at the end of the workday
- Recording actions, observations, and outcomes in real-time or as close to the event as possible (Correct answer)
- Only documenting unusual events or complications
- Using shorthand notes that can be expanded later if needed
Correct answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible
Real-time or near-real-time documentation in Lease Negotiation & Terms ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.
Question 25: What is the typical spacing for floor joists in residential construction?
- 24 inches
- 20 inches
- 12 inches
- 16 inches (Correct answer)
Correct answer: 16 inches
In typical residential wood-frame construction in the US, floor joists are commonly spaced 16 inches on center (16" O.C.). This spacing is a standard practice that provides adequate support for flooring materials and live loads, while also being efficient for material usage and construction. Other spacings like 12" or 24" O.C. are used in specific situations but 16" is the most common.
Question 26: How does risk management apply to daily practice in Environmental & Safety Assessment for Certified Home Inspector professionals?
- Only through responding to incidents after they occur
- By avoiding high-risk situations entirely
- Through annual safety audits exclusively
- Through proactive identification of potential hazards and implementation of preventive measures (Correct answer)
Correct answer: Through proactive identification of potential hazards and implementation of preventive measures
Effective risk management in Environmental & Safety Assessment requires proactive hazard identification and preventive measures, not just reactive responses. This approach reduces incidents, improves outcomes, and protects both professionals and clients.
Question 27: What is the primary purpose of a vapor barrier installed on the ground in a crawl space?
- To deter pest entry
- To insulate the floor above
- To prevent radon gas entry
- To prevent ground moisture from migrating upward into the structure (Correct answer)
Correct answer: To prevent ground moisture from migrating upward into the structure
A ground vapor barrier in a crawl space primarily prevents soil moisture from evaporating upward and causing condensation, rot, and mold in the floor framing.
Question 28: When reporting on energy inefficiency findings (e.g., poor insulation, single-pane windows), the most financially meaningful metric to provide buyers is:
- The U-factor of existing window glazing
- The SEER rating of the existing HVAC unit
- The R-value difference between existing and code-minimum insulation
- Estimated annual energy cost savings achievable through recommended upgrades (Correct answer)
Correct answer: Estimated annual energy cost savings achievable through recommended upgrades
Translating energy deficiencies into estimated annual dollar savings gives buyers a clear financial rationale for prioritizing energy upgrades.
Question 29: What is the most significant structural concern when an inspector observes a crawl space with standing water under the floor framing?
- Standing water is only a concern if it contacts the mudsill directly
- Standing water only affects the vapor barrier and is not a structural concern
- Prolonged moisture exposure causes wood rot and deterioration of structural members over time (Correct answer)
- The water increases humidity that can cause nail pops in the subfloor
Correct answer: Prolonged moisture exposure causes wood rot and deterioration of structural members over time
Persistent moisture in a crawl space accelerates wood decay and can also lead to termite infestation, both of which compromise the structural integrity of floor framing.
Question 30: A home inspector creates a Facebook Business Page. Which type of content tends to generate the highest organic engagement on social media?
- Stock photo images of generic houses
- Before-and-after photos of real inspection findings (Correct answer)
- Text-only posts listing service prices
- Shared news articles from unrelated industries
Correct answer: Before-and-after photos of real inspection findings
Authentic before-and-after inspection photos provide educational value and visual interest, generating significantly more engagement than generic content.
Question 31: What is the minimum clearance required between the top of a residential electrical panel and the ceiling?
- 3 feet
- 4 feet
- 6 feet (Correct answer)
- 6.5 feet
Correct answer: 6 feet
NEC requires a minimum of 6 feet of headroom above electrical panels to allow safe working space.
Question 32: What is the primary purpose of including an estimated remaining useful life (RUL) for major systems in a home inspection report?
- To satisfy lender requirements for mortgage underwriting
- To calculate annual depreciation for tax filing
- To set the asking price for the property
- To help buyers anticipate future capital expenditures and budget accordingly (Correct answer)
Correct answer: To help buyers anticipate future capital expenditures and budget accordingly
Providing RUL estimates allows buyers to project when major systems will need replacement and plan their finances accordingly.
Question 33: A home inspector tests a GFCI receptacle and it does not trip when the test button is pressed. What should be concluded?
- The GFCI is protecting downstream receptacles and should not trip locally
- The GFCI is functioning normally; test buttons do not always cause a trip
- The GFCI is defective or at end of life and should be replaced (Correct answer)
- The circuit needs a dedicated neutral for the test to work properly
Correct answer: The GFCI is defective or at end of life and should be replaced
A GFCI receptacle that fails to trip when its test button is pressed is defective and no longer provides ground fault protection.
Question 34: What is a 'lease abstract' and why is it important during due diligence on an investment property?
- A legally binding summary that replaces the full lease for recording purposes
- A financial model showing projected lease income over the term
- A condensed summary of key lease terms used for quick review and analysis (Correct answer)
- A document that voids undisclosed lease provisions
Correct answer: A condensed summary of key lease terms used for quick review and analysis
A lease abstract summarizes critical provisions—rent, term, options, and obligations—allowing investors and lenders to quickly assess lease risk without reading lengthy documents.
Question 35: A home inspector notes deferred maintenance totaling $18,500. How should this figure be presented in the inspection report?
- As an itemized cost estimate for each identified deficiency (Correct answer)
- As the home's adjusted market value
- As an insurance claim value
- As a single lump-sum deduction from listing price
Correct answer: As an itemized cost estimate for each identified deficiency
Best practice is to itemize each deficiency with its associated estimated cost so buyers can evaluate individual repair priorities.
Question 36: Why should a home inspection report avoid specifying a single fixed repair cost rather than a range?
- Contractor pricing varies; a range better reflects real-world cost uncertainty (Correct answer)
- Single figures trigger mandatory escrow holdbacks by lenders
- Fixed costs require a licensed contractor to verify before inclusion
- Single figures are legally binding in most states
Correct answer: Contractor pricing varies; a range better reflects real-world cost uncertainty
Material and labor costs vary by contractor, timing, and region; providing a realistic cost range more accurately reflects actual market variability.
Question 37: What is the minimum recommended clearance between a gas furnace flue vent and combustible materials?
- 6 inches
- 18 inches
- 1 inch (Correct answer)
- 12 inches
Correct answer: 1 inch
Single-wall metal flue pipe requires a minimum 6-inch clearance from combustibles, but high-efficiency furnaces with PVC venting require only 1 inch—however, B-vent requires 1 inch clearance per most codes.
Question 38: A tenant reports a persistent musty odor in their unit but no visible mold. What is the home inspector's most appropriate first step?
- Recommend the tenant break their lease
- Dismiss the complaint as subjective
- Inspect for hidden moisture sources such as plumbing leaks or HVAC condensation (Correct answer)
- Advise the tenant to use air fresheners
Correct answer: Inspect for hidden moisture sources such as plumbing leaks or HVAC condensation
Musty odors often indicate hidden moisture problems that should be investigated at their source before mold develops.
Question 39: What is the function of collar ties in roof framing?
- They connect the ridge board to the top plate of the exterior wall
- They transfer roof loads vertically down to the ceiling joists
- They resist rafter spread and help prevent the roof from pushing outward on the walls (Correct answer)
- They provide a nailing surface for attic flooring and storage
Correct answer: They resist rafter spread and help prevent the roof from pushing outward on the walls
Collar ties (or collar beams) connect opposing rafters near the ridge to resist the outward thrust that rafters exert on the wall plates.
Question 40: What is the role of a circuit breaker?
- Prevent circuit damage (Correct answer)
- Enhance signal strength
- Insulate conductors
- Provide wireless access
Correct answer: Prevent circuit damage
A circuit breaker is a crucial safety device in an electrical system. Its primary role is to automatically interrupt the flow of electricity when it detects an overcurrent or short circuit. This action prevents overheating of wires, potential fires, and damage to electrical appliances or the circuit itself, thereby protecting the entire electrical system.
Question 41: An inspector notes that a property's septic system is located near a protected wetland. The primary regulatory concern involves:
- ADA accessibility requirements
- International Residential Code Section R301
- Clean Water Act and state environmental regulations (Correct answer)
- Fair Housing Act compliance
Correct answer: Clean Water Act and state environmental regulations
Septic systems near wetlands raise concerns under the Clean Water Act and applicable state environmental laws protecting water quality.
Question 42: What does an inspector check to verify a forced-air furnace heat exchanger is NOT cracked?
- Color of the pilot light flame — it should be blue not orange
- Age of the furnace relative to average heat exchanger lifespan
- Carbon monoxide detector reading in the utility room only
- Signs of soot, rust, or CO presence in supply air registers; flame behavior near the exchanger (Correct answer)
Correct answer: Signs of soot, rust, or CO presence in supply air registers; flame behavior near the exchanger
Inspectors look for soot deposits around heat exchanger seams, observe the flame for flickering when the blower starts, and note any CO indicators as signs of a cracked exchanger.
Question 43: Under U.S. landlord-tenant law, a 'constructive eviction' claim by a tenant typically arises when:
- The landlord retaliates against a tenant for reporting code violations
- The tenant is evicted via court order for non-payment of rent
- The landlord's failure to maintain habitable conditions forces the tenant to vacate (Correct answer)
- The landlord physically removes the tenant's belongings from the property
Correct answer: The landlord's failure to maintain habitable conditions forces the tenant to vacate
Constructive eviction occurs when the landlord's neglect renders the property uninhabitable, effectively forcing the tenant to leave even without a formal eviction notice.
Question 44: What documentation practice is considered essential in Environmental & Safety Assessment within the Certified Home Inspector field?
- Recording actions, observations, and outcomes in real-time or as close to the event as possible (Correct answer)
- Completing all documentation at the end of the workday
- Using shorthand notes that can be expanded later if needed

Correct answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible
Real-time or near-real-time documentation in Environmental & Safety Assessment ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.
Question 45: What is the primary concern with wood rot in structural framing?
- Decreased aesthetic value
- Structural weakening (Correct answer)
- Increased insulation
- Discoloration
Correct answer: Structural weakening
Wood rot is caused by fungi that decompose the wood fibers, leading to a loss of strength and integrity. In structural framing, this weakening can compromise the load-bearing capacity of beams, joists, or studs, potentially leading to sagging, collapse, or other serious structural failures. Addressing wood rot is crucial for maintaining the safety and stability of a home.
Question 46: Which principle of value states that the value of an inferior property is enhanced by its proximity to superior properties?
- Principle of regression
- Principle of substitution
- Principle of progression (Correct answer)
- Principle of contribution
Correct answer: Principle of progression
The principle of progression holds that a lower-value property benefits from being located near higher-value properties, pulling its value upward.
Question 47: Which practice is most effective for reducing tenant turnover?
- Responding promptly to maintenance requests and keeping open communication (Correct answer)
- Raising rent annually regardless of market conditions
- Limiting lease renewal options
- Delaying maintenance requests to evaluate their urgency
Correct answer: Responding promptly to maintenance requests and keeping open communication
Prompt maintenance response and communication build tenant satisfaction, which is the strongest driver of lease renewal.
Question 48: What is the primary purpose of a backflow preventer installed on an outdoor hose bib?
- To allow winterization of exterior lines
- To regulate water pressure to safe levels
- To limit water flow to the irrigation system
- To prevent contaminated water from re-entering the potable supply (Correct answer)
Correct answer: To prevent contaminated water from re-entering the potable supply
A backflow preventer stops potentially contaminated water (from hoses submerged in pools, buckets, or chemicals) from being siphoned back into the potable water supply.
Question 49: During a property evaluation, an inspector finds that gutters are sloped away from downspouts. What should be reported?
- Improper slope will cause water to pool and overflow rather than drain (Correct answer)
- Only the downspout size matters for drainage efficiency
- This is acceptable as long as gutters are clean
- Gutters should always be level, so this is correct
Correct answer: Improper slope will cause water to pool and overflow rather than drain
Gutters must slope toward downspouts to ensure water drains properly; reverse slope causes pooling, overflow, and potential foundation damage.
Question 50: Which clause in a lease is designed to ensure landlords can recover the unit if a tenant stops paying rent?
- Sublet clause
- Holdover clause
- Default and eviction clause (Correct answer)
- Quiet enjoyment clause
Correct answer: Default and eviction clause
The default and eviction clause outlines the process a landlord must follow to regain possession of a unit when a tenant defaults on rent or lease terms.
Question 51: What is the primary concern when cellulose insulation becomes saturated with water due to a leak or flooding?
- It immediately ignites due to combustion of its paper fibers
- It compresses, promotes mold growth, and retains moisture causing long-term structural damage (Correct answer)
- It loses its fire-retardant treatment and becomes a code violation
- It releases toxic off-gases into the living space
Correct answer: It compresses, promotes mold growth, and retains moisture causing long-term structural damage
Wet cellulose compresses significantly, losing R-value permanently, and retains moisture that promotes mold growth and wood rot in surrounding structural members.
Question 52: What type of ventilation relies solely on natural forces such as temperature differences and wind pressure to move air, without any mechanical equipment?
- Natural ventilation (Correct answer)
- Energy recovery ventilation
- Mechanical ventilation
- Exhaust-only ventilation
Correct answer: Natural ventilation
Natural ventilation uses buoyancy (stack effect) and wind pressure differentials to move air through openings in the building envelope without any fans or powered equipment.
Question 53: Which federal law requires sellers to disclose known lead-based paint hazards in homes built before 1978?
- RCRA
- OSHA 1926
- TSCA Title IV (Residential Lead-Based Paint Hazard Reduction Act) (Correct answer)
- CERCLA
Correct answer: TSCA Title IV (Residential Lead-Based Paint Hazard Reduction Act)
The Residential Lead-Based Paint Hazard Reduction Act (Title IV of TSCA) mandates disclosure of known lead hazards before home sale.
Question 54: When a home inspector's report reveals significant structural issues, how does this typically affect the appraisal process?
- Appraisers ignore home inspection reports; they conduct independent structural assessments
- Structural issues only affect value in commercial properties
- The lender may require repairs before the appraisal can support the loan amount, or the appraiser may note the condition as a value-impacting factor (Correct answer)
- The inspection report automatically voids the appraisal
Correct answer: The lender may require repairs before the appraisal can support the loan amount, or the appraiser may note the condition as a value-impacting factor
Significant structural defects revealed in a home inspection can prompt lenders to require repairs as a condition of financing, and appraisers account for them in their value conclusion.
Question 55: When inspecting a heat pump, which defrost cycle symptom indicates normal operation?
- Ice forming permanently on the outdoor coil
- Refrigerant leaking from the service port
- Temporary steam rising from the outdoor unit during defrost (Correct answer)
- The indoor fan shutting off permanently during defrost
Correct answer: Temporary steam rising from the outdoor unit during defrost
Steam rising from the outdoor unit is normal during a heat pump defrost cycle as the reversing valve briefly switches to cooling mode to melt accumulated ice.
Question 56: An inspector observes that a bathroom has no window and no mechanical ventilation. The primary concern is:
- Ventilation is only required in kitchens, not bathrooms
- Lack of ventilation leads to moisture accumulation, mold growth, and accelerated deterioration (Correct answer)
- The room will be too dark for safe use
- Building code requires natural light in all bathrooms
Correct answer: Lack of ventilation leads to moisture accumulation, mold growth, and accelerated deterioration
Without ventilation, humidity from bathing has no escape path, promoting mold, mildew, and damage to finishes and structure over time.
Question 57: Which standard of practice is MOST important for ensuring quality in Property Evaluation & Analysis?
- Strictly adhering to the same procedure in every situation
- Using the most advanced technology available regardless of need
- Following evidence-based protocols while adapting to specific circumstances (Correct answer)
- Minimizing documentation to focus on practical work
Correct answer: Following evidence-based protocols while adapting to specific circumstances
Evidence-based protocols provide a foundation of proven practices, but effective Certified Home Inspector professionals must also adapt their approach based on specific circumstances and individual case needs within Property Evaluation & Analysis.
Question 58: A home inspector discovers visible mold on drywall in a basement. What is the MOST appropriate action?
- Note the finding and recommend evaluation by a qualified mold remediation specialist (Correct answer)
- Ignore it if the mold area is smaller than 10 square feet
- Scrub and document the mold during the inspection
- Spray bleach on the mold and mark it as resolved
Correct answer: Note the finding and recommend evaluation by a qualified mold remediation specialist
Home inspectors identify and document mold presence but defer remediation assessment to qualified specialists.
Question 59: Which of the following best defines 'quiet enjoyment' in a residential tenancy?
- A landlord's right to inspect the unit quietly
- A clause requiring tenants to be quiet after 10 PM
- The tenant's right to a noise-free environment at all times
- The tenant's right to use and occupy the premises without landlord interference (Correct answer)
Correct answer: The tenant's right to use and occupy the premises without landlord interference
Quiet enjoyment is a legal covenant guaranteeing the tenant's right to undisturbed possession of the rented premises.
Question 60: Which condition in an attic most directly indicates inadequate ventilation?
- Ridge vent installation along the peak
- Presence of blown-in insulation
- Soffit vents visible along the eaves
- Rust stains on nail tips penetrating the roof deck (Correct answer)
Correct answer: Rust stains on nail tips penetrating the roof deck
Rust on nail tips in an attic indicates condensation is forming on cold metal surfaces, a classic sign of inadequate ventilation and moisture accumulation.
Question 61: Which lease provision protects a tenant from rent increases tied to rising property taxes or operating costs in a gross lease?
- Base year protection
- Expense stop clause (Correct answer)
- CPI escalation cap
- Net floor provision
Correct answer: Expense stop clause
An expense stop sets the maximum operating expense amount the landlord absorbs; costs above the stop are passed to the tenant, while a gross lease with no stop shields tenants from all increases.
Question 62: When inspecting a chimney, which condition requires immediate notation as a safety hazard?
- Mortar joints that are slightly recessed
- Missing or deteriorated chimney cap allowing rain entry (Correct answer)
- Flue liner with minor staining from creosote
- Chimney crown with a hairline crack near the edge
Correct answer: Missing or deteriorated chimney cap allowing rain entry
A missing or damaged chimney cap allows water, animals, and debris to enter the flue, creating fire hazards, moisture damage, and blocked draft conditions.
Question 63: A tenant requests an accommodation for a service animal under the Fair Housing Act. The lease prohibits pets. What is the correct response?
- Charge the tenant a pet deposit for the service animal
- Require the tenant to relocate to a pet-friendly unit
- Enforce the no-pets clause and deny the request
- Grant a reasonable accommodation by waiving the no-pets policy for the service animal (Correct answer)
Correct answer: Grant a reasonable accommodation by waiving the no-pets policy for the service animal
The Fair Housing Act requires landlords to make reasonable accommodations for persons with disabilities, including allowing service and assistance animals regardless of pet policies.
Question 64: When inspecting a chimney, a home inspector notices that the mortar crown (chimney cap) has cracks running from the flue liner to the edge. What should the report state?
- The cracks are cosmetic and do not affect function
- Monitor annually; minor cracking is expected
- The flue liner should be replaced before the crown is addressed
- The crown should be sealed or replaced to prevent water penetration and spalling (Correct answer)
Correct answer: The crown should be sealed or replaced to prevent water penetration and spalling
Cracks in the chimney crown allow water to enter the masonry assembly, causing freeze-thaw spalling that can ultimately compromise the structural integrity of the chimney.
Question 65: Functional obsolescence in a home inspection context refers to:
- A loss in value due to outdated design or features that no longer meet current standards (Correct answer)
- Physical deterioration from age and wear

Moisture staining or mold on crawl space insulation or wood framing indicates water intrusion or inadequate vapor control that can lead to structural deterioration and poor indoor air quality.
Question 190: When inspecting a property, an inspector finds the crawl space access hatch is too small to enter. The correct course of action is:
- Document the limited access, inspect as much as visible from the opening, and note what could not be inspected (Correct answer)
- Skip the crawl space and note nothing in the report
- Assume the crawl space is in acceptable condition if no exterior signs exist
- Require the seller to enlarge the access before completing the inspection
Correct answer: Document the limited access, inspect as much as visible from the opening, and note what could not be inspected
Home inspectors must document all access limitations and clearly state what areas could not be inspected so clients understand the scope of the evaluation.
Question 191: How does a 'buyer's market' typically affect negotiation on a home inspection report?
- Inspection findings have no bearing on price negotiations in any market
- Sellers always refuse repair requests in a buyer's market
- Buyers have less leverage to request repairs since sellers have multiple offers
- Buyers have more leverage to negotiate repairs or price reductions due to ample inventory (Correct answer)
Correct answer: Buyers have more leverage to negotiate repairs or price reductions due to ample inventory
In a buyer's market with high inventory and fewer competing buyers, buyers hold stronger negotiating power to request repairs or price concessions after inspection.
Question 192: A home inspector finds that a load-bearing wall has been partially removed without a header installed above the opening. What is the primary structural risk?
- The opening will allow drafts that increase heating and cooling costs
- Only load-bearing walls with plumbing inside require headers
- The risk is limited to the wall's drywall cracking from vibration
- The floor or roof structure above may deflect excessively or collapse due to lack of load transfer (Correct answer)
Correct answer: The floor or roof structure above may deflect excessively or collapse due to lack of load transfer
Without a properly sized header, loads from above have no structural path to the adjacent wall framing, causing deflection or potential structural failure.
Question 193: An inspector discovers that a garage door opener lacks auto-reverse functionality when tested with a 2x4 board placed in the path. This should be reported as:
- Acceptable for openers manufactured before 1993
- Within normal tolerance if the opener reverses within 5 seconds
- A minor issue only if children are not present
- A safety deficiency requiring correction regardless of opener age (Correct answer)
Correct answer: A safety deficiency requiring correction regardless of opener age
Auto-reverse is a critical safety feature; any opener that fails to reverse upon contact with an obstruction presents an entrapment and injury hazard.
Question 194: What is the primary purpose of including a 'force majeure' clause in a lease agreement?
- To allow rent increases during natural disasters
- To excuse performance obligations when extraordinary events beyond a party's control occur (Correct answer)
- To require insurance coverage for catastrophic property damage
- To give the landlord authority to inspect during emergencies
Correct answer: To excuse performance obligations when extraordinary events beyond a party's control occur
A force majeure clause suspends or excuses lease obligations when unforeseeable events—such as natural disasters, pandemics, or war—prevent performance.
Question 195: What is the minimum roof slope typically required for standard three-tab asphalt shingles to be installed without special underlayment modifications?
- 4:12
- 1:12
- 3:12 (Correct answer)
- 2:12
Correct answer: 3:12
Standard asphalt shingles require a minimum 3:12 slope; below this pitch, water drains too slowly and can back up under shingle laps, causing leaks.
Question 196: During lease negotiations, a tenant requests a 'co-tenancy clause.' What protection does this provide?
- Equal rights with the landlord over lease modifications
- Rent reduction rights if a key anchor tenant vacates the property (Correct answer)
- The right to share the lease with another business entity
- Protection from eviction if a co-signer defaults
Correct answer: Rent reduction rights if a key anchor tenant vacates the property
A co-tenancy clause allows tenants—especially retailers—to reduce rent or terminate the lease if an anchor tenant departs, reducing customer traffic.
Question 197: Which refrigerant is commonly used in modern residential HVAC systems?
- R-410A (Correct answer)
- R-12
- Ammonia
- R-22
Correct answer: R-410A
R-410A is widely used in residential systems due to its efficiency and lower environmental impact compared to older refrigerants like R-22.
Question 198: A smoke detector in a home built in 2005 is found hardwired but not interconnected with other detectors. What should the inspector note?
- Hardwired smoke detectors installed in new construction since 1993 must be interconnected (Correct answer)
- Battery backup detectors do not require interconnection
- This is acceptable — interconnection is only required after 2020
- Interconnection is only required in homes with more than two stories
Correct answer: Hardwired smoke detectors installed in new construction since 1993 must be interconnected
The NEC and model building codes have required hardwired smoke detectors in new construction to be interconnected since 1993 so all alarms sound together.
Question 199: What does 'ponding water' on a flat or low-slope roof indicate to a home inspector?
- Normal behavior in climates with frequent heavy rainfall
- The roof membrane is new and has not fully cured
- The roof was recently installed and the drains are still being adjusted
- Inadequate drainage or structural deflection requiring further evaluation (Correct answer)
Correct answer: Inadequate drainage or structural deflection requiring further evaluation
Ponding water (standing water remaining more than 48 hours after rain) on a flat roof indicates drainage deficiencies or structural sagging that accelerate membrane deterioration.
Question 200: When evaluating a sump pump, which finding indicates a potential problem?
- The float switch is set to activate at a low water level
- A battery backup unit is installed alongside the primary pump
- The pump is hardwired to a dedicated circuit
- The discharge pipe terminates less than 3 feet from the foundation (Correct answer)
Correct answer: The discharge pipe terminates less than 3 feet from the foundation
If the sump pump discharges too close to the foundation, water is re-introduced near the basement wall, defeating the purpose of the system.
