NHIE Interior Inspection 3 — Questions and Answers
Question 1: Which condition in an interior room most directly suggests the presence of asbestos-containing materials requiring further evaluation?
- Popcorn ceiling texture applied before 1980 (Correct answer)
- Vinyl baseboards with yellowing
- Hollow-core interior doors
- Single-pane window glazing
Correct answer: Popcorn ceiling texture applied before 1980
Spray-applied popcorn (acoustic) ceiling texture installed before 1980 frequently contained asbestos and warrants specialist testing before disturbance.
Question 2: A home inspector notices that handrail ends on an open stairway terminate abruptly in mid-air. This is a deficiency because:
- The handrail height is non-compliant
- Open ends create a catch hazard for clothing and body parts (Correct answer)
- Handrails must return to the wall on both ends
- The material is not an approved graspable profile
Correct answer: Open ends create a catch hazard for clothing and body parts
Handrail ends that do not return to the wall or post create a catch hazard where sleeves or body parts can become snagged, causing falls.
Question 3: What is the minimum required headroom clearance above a stairway per the IRC?
- 6 feet 0 inches
- 6 feet 4 inches
- 6 feet 6 inches
- 6 feet 8 inches (Correct answer)
Correct answer: 6 feet 8 inches
The IRC requires a minimum of 6 feet 8 inches of headroom measured vertically from the stair nosing to any obstruction above.
Question 4: During an interior inspection, an inspector finds windows that are painted shut. This is primarily reported because:
- It affects the energy efficiency rating of the window
- It eliminates the window as an emergency egress opening (Correct answer)
- Paint buildup reduces insulating value of the glazing
- It indicates the home was poorly maintained overall
Correct answer: It eliminates the window as an emergency egress opening
Painted-shut windows in sleeping rooms eliminate a required emergency escape and rescue opening, which is a life-safety deficiency.
Question 5: An inspector observes that an interior bearing wall has been partially removed without a beam. The most likely evidence of structural distress is:
- Drywall nail pops along the wall
- Sagging ceiling joists and cracked finishes above the opening (Correct answer)
- Squeaky floors on the level above
- Doors on adjacent walls that are difficult to open
Correct answer: Sagging ceiling joists and cracked finishes above the opening
Removing a bearing wall without installing an adequate beam transfers load unevenly, causing ceiling joists to deflect and finishes above to crack.
Question 6: Which type of interior crack pattern is most indicative of differential foundation settlement rather than normal shrinkage?
- Hairline cracks at drywall seams
- Horizontal cracks midway up concrete block walls
- Stair-step cracks following mortar joints in masonry walls (Correct answer)
- Vertical cracks at the corners of window openings
Correct answer: Stair-step cracks following mortar joints in masonry walls
Stair-step cracks following mortar joints in masonry walls are classic indicators of differential settlement where one portion of the foundation has moved relative to another.
Question 7: What is the primary purpose of a threshold at an exterior door?
- To provide a decorative transition between flooring materials
- To seal the gap between the door bottom and the floor against air and water infiltration (Correct answer)
- To prevent the door from swinging past 90 degrees
- To provide a gripping surface to prevent slipping
Correct answer: To seal the gap between the door bottom and the floor against air and water infiltration
Door thresholds create a weather-tight seal at the floor level, preventing air infiltration, water entry, and pest access under the door.
