1. During a home inspection, a foundation wall shows horizontal cracking and
inward bowing. The inspector should conclude that:
A. The condition is cosmetic only
B. Structural movement may be occurring
C. The wall requires painting only
D. The crack is caused by normal shrinkage only
Answer: B
Rationale: Horizontal cracks and bowing may indicate structural pressure or
foundation failure.
2. A home inspector discovers double-tapped breakers in an electrical panel.
This condition may cause:
A. Improved circuit capacity
B. Overheating and loose connections
C. Lower electrical load
D. Increased grounding efficiency
Answer: B
Rationale: Double tapping can create poor electrical contact and overheating
hazards.
3. A case scenario: An inspector observes dark staining around a chimney in the
attic. The MOST likely cause is:
,A. Termite activity
B. Roof flashing leakage
C. Plumbing failure
D. HVAC condensation only
Answer: B
Rationale: Chimney flashing failure commonly causes water intrusion near
chimneys.
4. GFCI protection is primarily intended to:
A. Increase appliance lifespan
B. Prevent electric shock hazards
C. Improve lighting efficiency
D. Reduce water pressure
Answer: B
Rationale: Ground-fault circuit interrupters protect against electrical shock.
5. A roof with curling asphalt shingles usually indicates:
A. Excess attic insulation
B. Aging or heat-related deterioration
C. Proper roof ventilation
D. Foundation movement
Answer: B
Rationale: Curling shingles are a common sign of roof aging or overheating.
6. An inspector notices white powder deposits on a basement wall. This
condition is called:
A. Delamination
B. Efflorescence
C. Oxidation
D. Galvanization
Answer: B
Rationale: Efflorescence occurs when water leaves mineral deposits on masonry.
7. A plumbing drain trap is designed to:
,A. Increase water pressure
B. Prevent sewer gases from entering the home
C. Improve drainage speed
D. Reduce hot water temperature
Answer: B
Rationale: Traps hold water to block sewer gas entry.
8. A home inspector should report exposed electrical splices because they:
A. Improve conductivity
B. Present a fire and shock hazard
C. Increase voltage stability
D. Reduce overheating risk
Answer: B
Rationale: Exposed splices lack protection and can create hazards.
9. A case scenario: A furnace burner flame appears yellow instead of blue. The
MOST likely concern is:
A. Proper combustion
B. Incomplete combustion and possible carbon monoxide production
C. Excess airflow only
D. Correct fuel mixture
Answer: B
Rationale: Yellow flames indicate incomplete combustion.
10. A stairway without a handrail is considered:
A. Acceptable in all homes
B. A potential safety hazard
C. A cosmetic defect only
D. Normal for older homes
Answer: B
Rationale: Missing handrails increase fall risk.
11. A roof sag visible from the exterior may indicate:
, A. Proper structural loading
B. Structural failure or water damage
C. Cosmetic aging only
D. Adequate roof ventilation
Answer: B
Rationale: Sagging can indicate compromised framing.
12. An inspector observes reversed polarity at a receptacle. This means:
A. Ground and neutral are reversed
B. Hot and neutral wires are reversed
C. Circuit breaker is oversized
D. Voltage is too low
Answer: B
Rationale: Reverse polarity creates shock hazards.
13. A case scenario: Water stains are present beneath a second-floor bathroom.
The MOST likely cause is:
A. Foundation movement
B. Plumbing leakage
C. Roof ventilation failure
D. Electrical overheating
Answer: B
Rationale: Bathroom leaks commonly stain lower ceilings.
14. The primary purpose of attic ventilation is to:
A. Increase insulation weight
B. Reduce heat and moisture buildup
C. Strengthen roof decking
D. Prevent plumbing leaks
Answer: B
Rationale: Ventilation controls moisture and temperature.
15. A cracked heat exchanger in a furnace is dangerous because it may allow:
