North Carolina Home Inspector Exam
Preparation Guide 2026: Comprehensive
Practice Questions, Verified Answers,
Detailed Rationales, and In-Depth Review for
Licensing Success
Question 1
During a home inspection in North Carolina, an inspector
observes active water intrusion in a crawlspace that has
resulted in visible fungal growth on structural members.
What is the MOST appropriate action?
A. Identify the growth as toxic mold and recommend
immediate remediation
B. Ignore the growth because mold identification is outside
the scope of a home inspection
C. Describe the observed conditions, report moisture
intrusion, and recommend further evaluation or corrective
action
D. Collect samples and provide a laboratory-based mold
analysis
Answer: C
Rationale: Home inspectors are not required to determine
mold type or toxicity. However, they must report visible
,evidence of moisture intrusion and conditions that may
adversely affect the structure. Recommending further
evaluation by a qualified specialist is appropriate. Diagnosing
mold species exceeds the normal scope of a home inspection.
Question 2
A 200-amp service panel contains two conductors terminated
under a breaker designed for a single conductor. This
condition is commonly known as:
A. A bootleg connection
B. A double tap
C. A parallel feeder
D. A multiwire branch circuit
Answer: B
Rationale: A double tap occurs when more than one
conductor is connected to a terminal intended for a single
conductor. This can result in loose connections, overheating,
and electrical hazards unless specifically permitted by the
manufacturer's listing.
Question 3
Which roof defect is MOST likely to result in structural
damage if left uncorrected over an extended period?
A. Minor granular loss on asphalt shingles
,B. Slight fading of roofing material
C. Chronic flashing failure around roof penetrations
D. Cosmetic staining from algae
Answer: C
Rationale: Failed flashing around chimneys, vents, and
skylights commonly allows water intrusion into concealed
structural components. Long-term leakage can cause rot,
deterioration, and structural damage that may not be
immediately visible.
Question 4
A masonry chimney has significant mortar deterioration
between bricks above the roofline. The condition should be
reported because it may:
A. Improve draft performance
B. Increase chimney efficiency
C. Reduce creosote accumulation
D. Permit moisture penetration and compromise structural
stability
Answer: D
Rationale: Deteriorated mortar joints allow water to enter the
chimney structure. Freeze-thaw cycles can accelerate
damage, leading to loose masonry and potential collapse of
portions of the chimney.
, Question 5
When inspecting a foundation wall, a horizontal crack in a
concrete block wall is generally considered:
A. Less significant than a hairline shrinkage crack
B. A normal settlement crack
C. A cosmetic defect only
D. A potentially serious indication of lateral soil pressure
Answer: D
Rationale: Horizontal cracks in masonry foundation walls
often result from lateral pressure exerted by surrounding soil.
Such movement may indicate structural concerns requiring
further evaluation by a qualified professional.
Question 6
An inspector observes reversed polarity at several
receptacles. The primary concern is:
A. Increased electrical efficiency
B. Reduced breaker protection
C. Potential shock hazards due to energized components
being improperly connected
D. Excessive voltage drop
Answer: C
