1. Which of the following is the primary purpose of a building code?
A. Increase property value
B. Ensure public safety and welfare
C. Minimize construction costs
D. Promote architectural style
Rationale: Building codes exist primarily to protect public health,
safety, and welfare by regulating construction standards.
2. What is the minimum required ceiling height for habitable rooms
according to most building codes?
A. 7 feet
B. 8 feet
C. 6 feet 6 inches
D. 7 feet 6 inches
Rationale: Most codes, including the IBC, require a minimum ceiling

3. During an inspection, you notice structural cracks in a load-
bearing wall. What should you do first?
A. Paint over the cracks
B. Report the cracks to a structural engineer
C. Ignore them if they are small
D. Seal the cracks with silicone
,Rationale: Structural cracks in load-bearing walls can indicate serious
integrity issues, and a licensed structural engineer should assess
them.
4. The fire-resistance rating of a wall refers to:
A. The color of the wall
B. The time the wall can withstand fire exposure
C. The wall’s load capacity
D. The wall’s insulation type
Rationale: Fire-resistance ratings measure how long a wall can resist
fire, protecting occupants and slowing fire spread.
5. Which of the following is a primary concern when inspecting
plumbing systems?
A. Window alignment
B. Flooring materials
C. Leaks and water pressure
D. Roof slope
Rationale: Plumbing inspections focus on leaks, water pressure,
proper pipe installation, and compliance with codes.
6. What is the maximum allowable spacing for 2x4 wall studs in
residential construction?
A. 12 inches
B. 16 inches
C. 24 inches
D. 32 inches
,Rationale: Residential codes generally allow 2x4 wall studs to be

appropriate action?
A. Paint over it
B. Notify the property owner and recommend pest control
C. Ignore it if it’s minor
D. Remove the damaged wood only
Rationale: Termite damage compromises structural integrity,
requiring professional remediation.
12. What is the minimum slope for a residential roof to ensure
proper drainage?
A. 1:12
B. 2:12
C. 3:12
D. 5:12
Rationale: A minimum 3:12 slope ensures water drains effectively,
reducing leaks and structural damage.
