Sample Home Inspector Test Practice Questions
Try these questions from our free Home Inspector Test practice tests. The correct answer and an explanation follow each question.
A home inspector is evaluating the attic of a 1,800-square-foot house. According to the standard International Residential Code (IRC) 1/150 rule, what is the minimum required net free ventilating area (NFVA)?
- A. 6 square feet
- B. 10 square feet
- C. 12 square feet
- D. 15 square feet
Answer: C. 12 square feet
The standard IRC rule for attic ventilation is 1 square foot of net free ventilating area for every 150 square feet of attic floor space. Therefore, for an 1,800-square-foot attic, the calculation is 1800 / 150 = 12 square feet of NFVA.
A homeowner conducting a self-guided virtual inspection shows the inspector a GFCI outlet in the kitchen but does not test it. What should the inspector instruct the homeowner to do?
- A. Press the TEST button to trip the outlet, verify it loses power, then press RESET to restore it
- B. Simply verify the GFCI outlet is present and move on
- C. Check if the outlet is within 6 inches of the sink
- D. Replace the outlet immediately since it was not tested
Answer: A. Press the TEST button to trip the outlet, verify it loses power, then press RESET to restore it
GFCI outlets must be functionally tested — visual presence alone does not confirm the device will trip when it detects a ground fault.
An inspector finds that the grading around a home's foundation slopes toward the building. What is the recommended correction?
- A. Install interior drain tile
- B. Re-grade so the soil slopes away at least 6 inches over the first 10 feet
- C. Add window wells to basement windows
- D. Apply waterproof coating to the interior wall
Answer: B. Re-grade so the soil slopes away at least 6 inches over the first 10 feet
Positive drainage requires the grade to fall at least 6 inches within the first 10 feet from the foundation to direct surface water away and prevent basement seepage.
A home inspector observes that a double top plate in a load-bearing wall is only lapped at one corner of the building. What does this indicate?
- A. The top plate lap joints must be distributed around the building to tie wall sections together for lateral load transfer
- B. Double top plates only need to be lapped at corners; a single lap per corner is code-compliant
- C. Lap joints in the top plate have no structural significance in wood framing
- D. The top plate only needs to be continuous on exterior walls, not interior load-bearing walls
Answer: A. The top plate lap joints must be distributed around the building to tie wall sections together for lateral load transfer
Top plate laps must be staggered and distributed to continuously tie the wall framing together, transferring lateral forces across the entire perimeter.
