CPC CPC Building Codes, Permits & Inspections 1 — Questions and Answers
Question 1: What model code is most widely adopted across US states for commercial building construction?
- Uniform Building Code (UBC)
- International Building Code (IBC) (Correct answer)
- National Building Code (NBC)
- BOCA National Building Code
Correct answer: International Building Code (IBC)
The International Building Code (IBC), published by the International Code Council (ICC), has been adopted by most US states and jurisdictions as the basis for commercial construction regulations.
Question 2: What is the primary purpose of a 'Certificate of Occupancy (CO)'?
- Authorize the contractor to begin demolition
- Certify that a completed building complies with applicable codes and is safe for its intended use (Correct answer)
- Transfer property ownership
- Approve the contractor's final pay application
Correct answer: Certify that a completed building complies with applicable codes and is safe for its intended use
A CO is issued by the local building authority after final inspections confirm the building was constructed according to approved plans and meets all applicable codes.
Question 3: In the IBC, what does 'occupancy classification' determine?
- The number of floors allowed
- The applicable construction requirements, fire protection systems, egress design, and allowable area based on building use (Correct answer)
- The contractor's license class required
- The zoning district the building is located in
Correct answer: The applicable construction requirements, fire protection systems, egress design, and allowable area based on building use
Occupancy classification (A, B, E, F, H, I, M, R, S, U) drives virtually all code requirements including fire resistance, egress, sprinklers, and allowable construction types.
Question 4: What is a 'special inspection' as defined in IBC Chapter 17?
- An owner's inspection of contractor work quality
- Inspection by a qualified inspector to verify that specified materials, installations, fabrications, and site conditions comply with approved plans and specifications (Correct answer)
- OSHA safety inspection during construction
- Final inspection by the building official before CO issuance
Correct answer: Inspection by a qualified inspector to verify that specified materials, installations, fabrications, and site conditions comply with approved plans and specifications
Special inspections under IBC Chapter 17 are performed by approved inspectors to verify high-risk or complex construction, such as structural concrete, steel welding, and soil compaction.
Question 5: Which building code addresses fire resistance ratings of structural assemblies and the concept of 'construction type'?
- International Fire Code (IFC)
- International Building Code (IBC) Chapter 6 (Correct answer)
- International Mechanical Code (IMC)
- NFPA 70 (NEC)
Correct answer: International Building Code (IBC) Chapter 6
IBC Chapter 6 classifies buildings into Types I through V based on the fire resistance of their structural elements, which determines allowable height, area, and occupancy combinations.
Question 6: Under ADA (Americans with Disabilities Act), what minimum clear width must an accessible route provide?
- 24 inches
- 32 inches
- 36 inches (Correct answer)
- 44 inches
