Practice Question Bank & Answer Rationale
THIS PACK CONTAINS
149 exam-style multiple-choice questions. Each question includes the correct answer and a complete
rationale for focused revision.
COVERAGE
This exam assesses foundational and applied knowledge required for Connecticut home inspector interns,
covering structural systems, exterior and interior components, roofing, plumbing, electrical, heating and
cooling, insulation and ventilation, fireplaces and chimneys, and professional standards of practice including
Connecticut licensing regulations. Questions emphasize defect recognition, safety hazards, and accurate
reporting consistent with ASHI and InterNACHI standards.
STUDY GUIDE
Recommended duration: 2 hours. Passing target: 70% or higher (per Connecticut licensing examination
standards).

,1. During an inspection, you observe that a floor joist in the basement has been notched
at its center span to a depth exceeding one-sixth of its width. What is the most appropriate
action?
[ ] A. Report it as acceptable since the notch is in the center span where bending stress is lowest.
[ ] B. Report it as a structural defect requiring evaluation by a licensed structural engineer.
[ ] C. Recommend sistering a 2x6 alongside the joist as a standard repair.
[ ] D. Note it as a cosmetic issue and take no further action.
CORRECT: B. Report it as a structural defect requiring evaluation by a licensed structural engineer.
Notching a floor joist beyond one-sixth of its depth in the center span severely compromises its structural
integrity and violates IRC notching limits, requiring evaluation by a licensed structural engineer. Option A is
incorrect because center-span notching is actually more critical due to tensile stress. Option C suggests a
repair beyond the inspector's scope, and Option D ignores a genuine structural defect.
2. A gas-fired forced-air furnace shows a yellow, flickering flame and soot deposits on the
heat exchanger. Which condition is most likely indicated?
[ ] A. Normal combustion with adequate primary air
[ ] B. Incomplete combustion due to insufficient combustion air or a blocked flue
[ ] C. A properly functioning draft inducer motor
[ ] D. Excessive gas manifold pressure causing a lean burn
CORRECT: B. Incomplete combustion due to insufficient combustion air or a blocked flue
A yellow, flickering flame with soot indicates incomplete combustion, typically from insufficient combustion air,
a blocked flue, or improper gas/air mixture, and poses a carbon monoxide hazard. A blue flame indicates
normal combustion, ruling out A. A draft inducer would not cause soot, and excessive manifold pressure
would produce a louder, lifting flame rather than soot.
3. Which of the following is the minimum required clearance between a masonry chimney
and combustible framing per current code?
[ ] A. 1 inch
[ ] B. 2 inches
[ ] C. 4 inches
[ ] D. 6 inches
CORRECT: B. 2 inches
The International Residential Code and NFPA 211 require a minimum 2-inch airspace clearance between a
masonry chimney and combustible materials to prevent pyrolysis and fire. One inch is insufficient, while 4
and 6 inches exceed the minimum but are not the code-required standard.

,4. In a main electrical panel, you observe a white (neutral) conductor connected to a
circuit breaker terminal. What is the most accurate assessment?
[ ] A. This is acceptable if the conductor is re-identified with black tape.
[ ] B. This is a defect because neutral conductors must terminate only on the neutral bus.
[ ] C. This is a defect unless the panel is a subpanel.
[ ] D. This is acceptable for 240-volt circuits only.
CORRECT: A. This is acceptable if the conductor is re-identified with black tape.
A white conductor used as an ungrounded (hot) conductor is permitted only if it is permanently re-identified
with black or colored tape/marker at all terminations, per NEC 200.7. Option B is too absolute-re-identification
is allowed. Option C is incorrect because subpanels require separate neutral and ground buses, and Option
D is false since re-identification applies regardless of voltage.
5. Which type of plumbing supply pipe is most susceptible to failure from dezincification
in Connecticut's water chemistry?
[ ] A. Copper Type L
[ ] B. PEX-A
[ ] C. Brass (yellow brass) fittings and valves
[ ] D. Galvanized steel
CORRECT: C. Brass (yellow brass) fittings and valves
Dezincification selectively leaches zinc from yellow brass, causing pitting and failure, particularly in
aggressive or high-chloride water common in parts of Connecticut. Copper, PEX, and galvanized steel fail by
different mechanisms (pitting, UV/oxidation, and rust, respectively), making C the most accurate answer.
6. A roof covering consists of three tab asphalt shingles with significant granule loss,
curling edges, and exposed mat. What is the most appropriate reporting language?
[ ] A. Roof is in acceptable condition with normal wear.
[ ] B. Roof covering is at or near the end of its service life; replacement is recommended.
[ ] C. Roof requires only minor patching and sealing.
[ ] D. Roof condition cannot be determined without a moisture meter.
CORRECT: B. Roof covering is at or near the end of its service life; replacement is recommended.
Granule loss, curling, and exposed mat indicate advanced deterioration and that the shingles are at or near
the end of their useful life, warranting replacement. Option A understates the severity, Option C minimizes a
systemic issue, and Option D misstates the diagnostic method-visual inspection is sufficient to identify these
conditions.

, 7. During an inspection, you discover that the home inspector's report will be used in a
real estate transaction. Under Connecticut regulations, which statement about the
inspector's scope and limitations is correct?
[ ] A. The inspector must inspect for radon and mold as part of the standard inspection.
[ ] B. The inspector must disclose that the inspection is a visual, non-invasive examination and not a
code compliance inspection.
[ ] C. The inspector is required to provide a cost estimate for all recommended repairs.
[ ] D. The inspector must warrant that all systems will remain functional for one year.
CORRECT: B. The inspector must disclose that the inspection is a visual, non-invasive examination
and not a code compliance inspection.
Connecticut home inspection regulations and ASHI/InterNACHI standards require inspectors to disclose that
the inspection is a visual, non-invasive, non-code-compliance evaluation. Radon and mold are not part of the
standard inspection unless specifically contracted, cost estimates are not required, and no warranty of future
performance is implied.
8. An attic shows evidence of frost on the underside of the roof sheathing and rusted
roofing nails. Which condition is most likely responsible?
[ ] A. Inadequate attic ventilation combined with warm, moist air leakage from the living space
[ ] B. Excessive attic ventilation causing rapid cooling
[ ] C. A leaking roof covering allowing water intrusion
[ ] D. Insufficient insulation on the attic floor
CORRECT: A. Inadequate attic ventilation combined with warm, moist air leakage from the living
space
Frost on the roof sheathing and rusted nails indicate warm, moist air from the living space condensing and
freezing in a poorly ventilated attic, a classic sign of air leakage and inadequate ventilation. Excessive
ventilation would reduce condensation, roof leaks would typically show water staining rather than frost, and
insufficient insulation alone would not cause frost without a moisture source.
9. A concrete foundation wall in a basement exhibits a horizontal crack with slight bowing.
What is the most likely cause?
[ ] A. Shrinkage cracking from concrete curing
[ ] B. Lateral soil pressure and possible hydrostatic pressure
[ ] C. Settlement of the footing
[ ] D. Thermal expansion of the concrete
CORRECT: B. Lateral soil pressure and possible hydrostatic pressure
Horizontal cracks with bowing in a foundation wall are characteristic of lateral earth pressure and hydrostatic
pressure pushing inward, often requiring structural evaluation. Shrinkage cracks are typically vertical and
non-structural, settlement causes vertical or diagonal cracks, and thermal expansion rarely produces bowing.
