New York Home Inspector License Examination: Overview
The New York Home Inspector License Exam is designed to ensure candidates possess the
technical knowledge and professional ethics required to evaluate the safety and condition of
residential properties. To pass, you must demonstrate proficiency across several core content
areas, including:
• Structural Systems: Foundations, floors, walls, ceilings, and roof structures.
• Exterior Components: Siding, windows, doors, flashing, and trim.
• Roofing Systems: Roof coverings, drainage, flashings, and skylights.
• Plumbing Systems: Main water lines, fixtures, water heaters, and fuel storage.
• Electrical Systems: Service entrance, grounding, panels, and branch circuits.
• Heating and Cooling (HVAC): Furnaces, boilers, AC units, and distribution.
• Interior Systems: Walls, ceilings, floors, stairs, and insulation/ventilation.
• Fireplaces and Chimneys: Construction, clearance, and safety.
• Professional Practice: New York State laws, ethics, and report writing.
Batch 1: Practice Questions (1–100)
1. What is the minimum headroom required for a stairway according to most codes?
A. 6'2"
1
, Page 2 of 83
B. 6'6"
C. 6'8"
D. 7'0"
Rationale: A minimum headroom of 6 feet 8 inches is the standard requirement to prevent
injury and ensure safe passage for most adults.
2. What is the maximum riser height allowed for residential stairs?
A. 6 inches
B. 7 3/4 inches
C. 8 1/2 inches
D. 9 inches
Rationale: The International Residential Code (IRC), which New York follows, specifies a
maximum riser height of 7 3/4 inches to prevent tripping hazards.
3. In a typical residential electrical panel, what is the purpose of the "bonding" screw?
A. To connect the neutral bar to the hot bus bar.
B. To connect the neutral bar to the metal enclosure/ground.
C. To prevent the circuit breakers from tripping.
D. To regulate the voltage entering the home.
2
, Page 3 of 83
Rationale: In a service entrance panel, the bonding screw ensures that the metal cabinet is
electrically tied to the neutral/grounding system, providing a path for fault current.
4. When inspecting a roof, a "kick-out" flashing should be installed where:
A. Two different roof slopes meet.
B. A roof eave terminates against a vertical sidewall.
C. A chimney penetrates the roof peak.
D. The gutter connects to the downspout.
Rationale: Kick-out flashing diverts water away from the wall cladding and into the gutter,
preventing water intrusion into the wall assembly.
5. Which of the following is a sign of a possible "backdrafting" condition in a gas water
heater?
A. Soot or scorching at the draft hood.
B. Water dripping from the T&P valve.
C. A blue flame in the burner chamber.
D. High water pressure at the faucets.
Rationale: Scorching or soot around the draft hood indicates that combustion gases are not
exhausting correctly and are spilling back into the living space.

6. A GFCI (Ground Fault Circuit Interrupter) is designed to trip when it senses a difference in
current between:
A. The ground wire and the neutral wire.
B. The hot wire and the neutral wire.
C. Two different hot wires.
D. The circuit breaker and the outlet.
Rationale: A GFCI monitors the balance of current; if the "return" current on the neutral differs
from the "supply" on the hot by more than 5mA, it trips to prevent electrocution.
7. In a crawl space, what is the primary purpose of a vapor barrier (ground cover)?
A. To prevent insects from entering the home.
B. To reduce the amount of moisture evaporating from the soil.
C. To provide a clean surface for the inspector to crawl on.
D. To insulate the floor above.
Rationale: Soil moisture can lead to high humidity, wood rot, and mold in crawl spaces; a vapor
barrier blocks this evaporation.
8. What is the minimum required thickness for a solid wood "fire door" between a garage and
a living space?
