FREE Home Inspector MCQ Questions and Answers

Question 1

What is the International Residential Code's (IRC) recommended minimum slope for graded soil near a building's foundation?

Accepted Answer

≥ 6"/10'

Answer

The International Residential Code (IRC) mandates specific grading requirements around a building's foundation to ensure proper drainage. The finished grade should slope away from the foundation at a minimum rate of 6 inches over the first 10 feet. This prevents rainwater from pooling against the foundation, which could lead to moisture intrusion, erosion, and potential structural damage.

Question 2

Which of the following is not a heating system that uses solid fuel?

Accepted Answer

An electric heater

Answer

Solid fuel heating systems generate heat by burning solid materials such as wood (e.g., woodstoves, fireplaces) or coal (e.g., coal furnaces). An electric heater, in contrast, operates by converting electrical energy directly into heat through resistance. Therefore, an electric heater does not use solid fuel and belongs to a different category of heating systems.

Question 3

Every sleeping area and basement must have an easily accessible emergency exit window. How big of a window must this be?

Accepted Answer

At least 5.7 sq. ft

Answer

Building codes require emergency escape and rescue openings, commonly known as egress windows, in all sleeping rooms and basements. For these windows to serve as a safe exit in an emergency, they must have a minimum clear openable area of at least 5.7 square feet (or 5.0 square feet for ground floor openings). This ensures occupants can escape and emergency responders can enter.

Question 4

You are looking over a residence. Each system component that is easily accessible must be observed and tested. Which of the following is not regarded as a feature that is easily accessible in a room?

Accepted Answer

Nails or screws in the floor

Answer

Home inspectors are required to observe and test readily accessible components of a residence. Easily accessible features include items that can be seen, operated, or tested without requiring tools or destructive methods, such as windows, doors, and visible fixtures. Nails or screws embedded in the floor are part of the building's structure or finish and are not considered easily accessible for routine inspection or testing.

Question 5

Each building requires the installation of branch circuits in several locations. One of them is not which of the following?

Accepted Answer

An office or bedroom

Answer

The National Electrical Code (NEC) mandates dedicated branch circuits for specific high-load areas or appliances to prevent overloading and ensure safety. These typically include laundry rooms, bathrooms (for receptacles), and central HVAC equipment. While offices and bedrooms require general lighting and receptacle circuits, they do not typically require dedicated branch circuits in the same way as these other high-demand locations.
