A sloping roof ends against a sidewall just above a gutter. The step flashing is intact, but a narrow band of siding directly below the end of the roof is stained and soft. The gutter is clear and does not overflow. Which missing detail best explains this localized damage?
Correct answer: B - Kick-out flashing at the roof-to-wall termination
An older house retains galvanized-steel water-distribution piping. Pressure at the service entrance is 62 psi with fixtures closed and remains 58 psi while two bathtub spouts run. At both two-handle tub faucets, hot and cold flows weaken markedly when the fixtures are used together. This combination most strongly favors:
Correct answer: A - Internal restriction in the water-distribution piping
To create a vaulted ceiling, an owner removed the low horizontal ties between opposing rafters. The roof still has an ordinary ridge board, not a supported structural ridge beam, and the upper collar ties remain. Why do those collar ties not replace the removed members' principal structural function?
Correct answer: C - The removed ties restrained outward thrust at the exterior walls.
A second-floor bedroom window has a frame measuring 30 by 48 inches, but its actual unobstructed opening is 24 by 32 inches. It opens without keys or tools; its sill is 40 inches above the interior floor and 14 feet above exterior grade. The applicable criteria require at least 5.7 square feet of net clear opening, 20 inches of clear width, 24 inches of clear height, and a sill no higher than 44 inches. Which evaluation is correct?
Correct answer: B - It fails because the net clear opening is approximately 5.33 square feet.
During a combustion-safety assessment on a calm day, a natural-draft water heater vents normally with the kitchen exhaust hood off. With doors and windows unchanged, switching on the hood produces spillage at the draft hood; switching it off restores upward flow. What best accounts for the immediate change in vent performance?
Correct answer: C - House depressurization from inadequate replacement air
The service disconnect is at the meter. A four-wire feeder supplies a panel inside the same house, where the neutral bar is bonded to the metal enclosure. The equipment grounding conductors also connect to the enclosure. Which statement accurately describes this arrangement?
Correct answer: C - Normal neutral current can divide onto the equipment grounding paths.
At a GFCI receptacle marked 'No Equipment Ground,' the integral TEST button trips the device and cuts power to its face. After reset, a plug-in tester indicates an open ground, consistent with the known ungrounded circuit, but its GFCI test button does not trip the device. How should the inspector reconcile these results?
Correct answer: D - Recognize the plug-in test's dependence on an equipment grounding path.
An infrared scan shows a cool patch beneath a bathroom window. There is no visible staining, and the camera is the only instrument used so far. The client asks whether the image proves a concealed leak. What has the inspection established at this point?
Correct answer: A - An apparent temperature anomaly, not yet a confirmed moisture problem
A 16-year-old storage water heater produces hot water, and the inspection reveals no leakage, corrosion, or observable safety defect. The buyer asks whether its age makes replacement immediately necessary. Which report statement distinguishes present condition from replacement planning?
Correct answer: A - It operated during inspection; budget for replacement without predicting a specific failure date.
Before the inspection begins, the client reads an agreement that includes operating plumbing fixtures but excludes laboratory water testing. The house has a private well. The client asks the inspector to certify that the water is safe to drink if the faucets flow normally. The appropriate clarification is:
Correct answer: D - Fixture operation does not establish potability; water-quality testing is a separate service.
