measures foundational knowledge of residential building systems, New York-specific regulations, and professional
ethics. The assessment emphasizes real-world application, scenario-based decision-making, and compliance with

completion demonstrates competency to practice as a licensed home inspector in New York State.
,SECTION ONE: QUESTIONS 1–100
Question 1
A home inspector observes horizontal cracks in a poured concrete foundation wall. What is the most likely
implication?
A. Shrinkage cracking due to curing
B. Frost heave damage
C. Excessive hydrostatic pressure from backfill
D. Settlement of footing reinforcing steel
🟢C
🔴 RATIONALE: Horizontal cracking in poured concrete foundations is most often caused by excessive lateral
hydrostatic pressure from water-saturated backfill soil, which can lead to wall bowing or structural failure. A
(shrinkage) tends to produce vertical or diagonal cracks. B (frost heave) affects footings and grade beams, not
mid-wall horizontally. D is rare and unrelated to typical horizontal cracking.
Question 2
Under New York State regulations, which condition must a home inspector include in a written report as a
material defect?
A. A missing GFCI outlet in a 1970s kitchen
B. A single hairline crack in a concrete driveway
C. A dated but functioning sump pump
D. A roof with three layers of asphalt shingles
,🟢A
🔴 RATIONALE: New York’s home inspector standards define material defects as conditions that significantly
affect the property’s value or safety. Missing GFCI protection in a wet area like a kitchen is a shock hazard and a
material defect. B is cosmetic; C is functional; D is an observation but not necessarily a defect if no leaks.
Question 3
During an inspection, the client tells the inspector they want the report to "ignore the minor stuff and just focus
on deal-breakers." The inspector should:
A. Verbally agree but still report everything in writing
B. Decline and explain that all systems must be reported as per standards of practice
C. Omit minor items to save time
D. Reduce the fee for a shorter report
🟢B
🔴 RATIONALE: New York standards of practice require inspectors to report all observed deficiencies, not just
those the client deems major. Agreeing to omit items violates professional ethics and licensing rules. B is the
correct ethical and legal response.
Question 4
Which of the following is the minimum vertical clearance required for a walkway beneath a residential deck?
A. 6 feet 0 inches
B. 6 feet 6 inches
C. 7 feet 0 inches
D. 7 feet 6 inches
, 🟢B
🔴 RATIONALE: The International Residential Code (IRC) generally requires 6 feet 8 inches for halls and ceilings,
but for exterior walkways under decks, the typical minimum is 6 feet 6 inches unless exceptions apply. New York
adopts IRC with amendments. B is the most accurate among the options.
Question 5
A home inspector finds an electric water heater with no temperature and pressure (T&P) relief valve discharge
pipe. The discharge pipe is missing entirely. What action is required?
A. Note that the T&P valve exists and is functional
B. Recommend installation of a discharge pipe terminating within 6 inches of the floor
C. No action because T&P valves are not required on electric water heaters
D. Suggest the homeowner add a cap to the valve
🟢B
🔴 RATIONALE: A missing discharge pipe is a serious safety hazard (risk of scalding or explosion). The inspector
must recommend proper installation, with discharge terminating 6 inches above the floor or into an indirect
waste receptor. B is correct; C is false (all water heaters need T&P protection).
Question 6
What is the maximum allowable gap between guardrail balusters in a residential home built under current New
York codes?
A. 3 inches
B. 4 inches
C. 4 3/8 inches
D. 6 inches
