CPC CPC Building Codes, Permits & Inspections 2 — Questions and Answers
Question 1: What is 'zoning' and how does it affect construction projects?
- A financial accounting method for project budgets
- A land use regulatory system that specifies permitted uses, setbacks, height limits, and density for different geographic districts (Correct answer)
- The process of dividing a large project into separate contracts
- A method of organizing workers into specialized crews
Correct answer: A land use regulatory system that specifies permitted uses, setbacks, height limits, and density for different geographic districts
Zoning ordinances divide jurisdictions into districts with specific land use rules, and any construction project must comply with applicable setbacks, height limits, FAR, and permitted uses.
Question 2: What is a 'variance' in the context of zoning and building regulations?
- A discrepancy between bid and actual costs
- Authorization to deviate from specific zoning or code requirements due to unique site conditions or hardship (Correct answer)
- A change order for extra work
- A permit extension for delayed projects
Correct answer: Authorization to deviate from specific zoning or code requirements due to unique site conditions or hardship
A variance grants relief from specific zoning standards (setbacks, height, lot coverage) when strict application would cause undue hardship due to unique property characteristics.
Question 3: Which code governs the installation of electrical systems in commercial buildings in the United States?
- International Mechanical Code (IMC)
- International Fire Code (IFC)
- NFPA 70 — National Electrical Code (NEC) (Correct answer)
- International Plumbing Code (IPC)
Correct answer: NFPA 70 — National Electrical Code (NEC)
NFPA 70 (NEC) is the national standard for electrical installations and is adopted by most jurisdictions as the legal standard for commercial and residential electrical work.
Question 4: What is the 'plan check' (plan review) process and why is it required before permit issuance?
- A contractor's internal quality review before bidding
- A building department review of construction documents for code compliance before issuing a building permit (Correct answer)
- An owner's review of shop drawings
- An architect's final check before signing drawings
Correct answer: A building department review of construction documents for code compliance before issuing a building permit
Plan check is a building department review that verifies construction documents comply with applicable codes (structural, fire, accessibility, energy) before work begins.
Question 5: Which inspection is typically the first required during framing of a wood-frame building?
- Insulation inspection
- Rough framing inspection (Correct answer)
- Foundation inspection
- Final inspection
Correct answer: Rough framing inspection
Rough framing inspection occurs after all structural framing, blocking, sheathing, fastening, and backing are in place but before they are concealed by insulation or drywall.
Question 6: What does an 'as-built' drawing set document, and why is it important?
- The original design intent before construction began
- The actual constructed conditions including field changes, revised dimensions, and equipment locations (Correct answer)
- The contractor's bid drawings used for pricing
- Preliminary design sketches before permit submission
Correct answer: The actual constructed conditions including field changes, revised dimensions, and equipment locations
As-built drawings record actual field conditions and deviations from original design, creating an accurate record essential for future maintenance, renovations, and permitting.
