When inspecting interior walls, which condition most strongly indicates moisture intrusion behind the surface?
Answer: Efflorescence staining at the base
Efflorescence (white mineral deposits) on interior walls indicates water is moving through the material, signaling active moisture intrusion.
A home inspector finds that several interior doors bind and fail to latch properly on the upper corner. What is the most likely cause?
Answer: Foundation settlement or structural movement
Doors binding at the upper corner on the latch side typically indicate differential settlement or structural racking that has distorted the door frame.
Which flooring defect represents the greatest safety hazard that an inspector must report?
Answer: Soft or spongy areas indicating subfloor deterioration
Soft or spongy flooring indicates subfloor rot or structural damage that could cause a fall-through, making it the most immediate safety concern.
An inspector observes staining on the ceiling directly below a bathroom. What is the FIRST step in determining the cause?
Answer: Inspect the bathroom above for plumbing leaks and caulking failures
The bathroom above is the most probable source; inspecting plumbing connections, supply lines, and drain seals is the logical first diagnostic step.
What does 'truss uplift' typically cause in a home's interior?
Answer: Separation between partition walls and the ceiling
Truss uplift occurs when the bottom chord of a truss moves upward in cold weather, pulling attached partition walls away from the ceiling drywall.
When inspecting a stairway, the maximum allowable variation in riser height between any two risers in a flight is:
Answer: 3/8 inch
Most building codes, including IRC, limit riser height variation within a flight to 3/8 inch to prevent tripping hazards.
An inspector observes dark streaking on a bathroom ceiling with no active roof leak. The most probable cause is:
Answer: Condensation from inadequate exhaust ventilation
Dark mold or mildew streaking on bathroom ceilings without roof leaks typically results from moisture-laden air condensing on a poorly ventilated surface.
