1. During a residential inspection, an inspector observes that a wood-framed
exterior wall contains a large opening for a garage door. Which structural
condition is most important to verify above the opening?
A. The wall insulation is continuous
B. The header is properly sized and supported
C. The vapor retarder extends across the opening
D. The siding overlaps the foundation
Answer: B. The header is properly sized and supported
Rationale: The header transfers loads from the framing above the opening to
the supporting studs or posts at each side. An improperly sized or supported
header can result in excessive deflection or structural failure.
, 2. A residential building has a wood floor system supported by beams. What is
the primary purpose of checking beam bearing at its supports?
A. To improve insulation performance
B. To prevent condensation
C. To ensure loads are safely transferred to the supporting structure
D. To increase floor finish durability
Answer: C. To ensure loads are safely transferred to the supporting structure
Rationale: Adequate bearing provides a reliable load path from beams into
posts, walls, foundations, or other supporting elements.
3. A stairway serving a dwelling has open risers. Which condition should cause
the inspector the greatest concern?
A. The stair finish is painted
B. The stair width exceeds the minimum
C. The openings permit a child to pass through
D. The handrail is made of wood
Answer: C. The openings permit a child to pass through
Rationale: Stair opening limitations are intended to reduce the risk of falls and
entrapment, particularly for young children.
4. A foundation wall exhibits a long horizontal crack accompanied by inward
displacement. What should the inspector consider first?
A. Cosmetic painting defects
B. Possible structural soil or lateral-pressure effects
C. Interior finish quality
D. Roof ventilation
Answer: B. Possible structural soil or lateral-pressure effects
,Rationale: Horizontal cracking with displacement can indicate significant lateral
soil pressure or foundation movement and warrants evaluation of structural
stability.
5. Which condition most directly indicates that a residential building has an
inadequate drainage plane?
A. The roof has asphalt shingles
B. Exterior water can enter behind the cladding without a drainage path
C. Interior walls are painted
D. The foundation is concrete
Answer: B. Exterior water can enter behind the cladding without a drainage
path
Rationale: A drainage plane and appropriate flashing help control water that
penetrates exterior cladding and direct it toward the exterior.
6. A deck ledger is attached to a dwelling without adequate flashing. What is
the primary inspection concern?
A. Increased snow visibility
B. Water intrusion and decay at the building envelope
C. Reduced ceiling height
D. Excessive electrical voltage
Answer: B. Water intrusion and decay at the building envelope
Rationale: Improperly flashed ledger connections can allow water into the wall
assembly, causing concealed decay and potentially compromising the structural
connection.
7. Which framing condition generally requires the inspector to verify that the
opening has adequate structural support?
A. A small interior closet
B. A doorway cut through a bearing wall
, C. A nonbearing partition
D. A baseboard opening
Answer: B. A doorway cut through a bearing wall
Rationale: Removing or interrupting studs in a bearing wall requires a properly
designed header and supporting framing to maintain the load path.
8. A crawl-space foundation has standing water after rainfall. Which issue
should receive priority?
A. Wall paint color
B. Potential moisture damage and drainage deficiencies
C. Interior cabinet alignment
D. Window screen condition
Answer: B. Potential moisture damage and drainage deficiencies
Rationale: Persistent crawl-space moisture can contribute to wood decay, mold
growth, corrosion, and deterioration of building materials.
9. What is the primary purpose of foundation footing reinforcement where
reinforcement is required?
A. Improve paint adhesion
B. Resist structural stresses and help control cracking
C. Increase attic ventilation
D. Reduce electrical resistance
Answer: B. Resist structural stresses and help control cracking
Rationale: Reinforcement contributes tensile capacity and helps the foundation
resist stresses that concrete alone handles poorly.
10.A roof rafter has been cut significantly to install mechanical equipment.
What should an inspector determine?
