1. What is the primary purpose of a home inspection?
A. To guarantee that no defects exist in the home
B. To estimate future repair costs
C. To provide a visual assessment of the home's condition at
the time of inspection
D. To determine the home's market value
Correct Answer: C. To provide a visual assessment of the
home's condition at the time of inspection.
Rationale: A home inspection is a non-invasive visual
examination of accessible systems and components. It does not
guarantee a defect-free home, establish value, or estimate
repair costs.
2. Which foundation crack generally requires the greatest
concern?
A. Hairline shrinkage crack
B. Vertical crack less than 1/8 inch wide
,C. Horizontal crack with inward wall movement
D. Surface crack in concrete
Correct Answer: C. Horizontal crack with inward wall
movement.
Rationale: Horizontal cracks accompanied by wall displacement
often indicate significant structural pressure from surrounding
soil and should be evaluated by a structural engineer.
3. Which roofing material typically has the shortest service
life?
A. Slate
B. Clay tile
C. Asphalt three-tab shingles
D. Metal roofing
Correct Answer: C. Asphalt three-tab shingles.
Rationale: Three-tab asphalt shingles generally last 15–25
years, whereas slate, tile, and metal roofs often last
considerably longer.
4. Flashing around roof penetrations primarily prevents:
A. Wind damage
B. Ice formation
,C. Water intrusion
D. Heat loss
Correct Answer: C. Water intrusion.
Rationale: Flashing seals roof penetrations and joints,
preventing rainwater from entering the building envelope.
5. A GFCI receptacle is designed to protect against:
A. Low voltage
B. Overheating
C. Ground faults causing electrical shock
D. Lightning strikes
Correct Answer: C. Ground faults causing electrical shock.
Rationale: Ground-Fault Circuit Interrupters detect current
leakage and quickly disconnect power to reduce the risk of
electric shock.
6. The purpose of an electrical service panel is to:
A. Heat the home
B. Distribute electrical power safely throughout the house
C. Filter electrical current
D. Increase voltage
, Correct Answer: B. Distribute electrical power safely
throughout the house.
Rationale: The service panel receives electrical power from the
utility and distributes it through branch circuits protected by
breakers or fuses.
7. Which plumbing pipe material is most susceptible to
internal corrosion?
A. Copper
B. PVC
C. Galvanized steel
D. PEX
Correct Answer: C. Galvanized steel.
Rationale: Galvanized steel pipes corrode internally over time,
restricting water flow and increasing the likelihood of leaks.
8. A properly installed P-trap primarily serves to:
A. Increase water pressure
B. Prevent sewer gases from entering the home
C. Filter debris
D. Improve drainage speed
