## SECTION I: PROPERTY AND BUILDING INSPECTION / SITE REVIEW
### A. Site Conditions (Grading, Drainage, Vegetation, Retaining Walls)
**1. A home inspector observes that the soil around a foundation slopes toward the structure, and
there is visible evidence of moisture intrusion in the basement. Which of the following is the
MOST important immediate recommendation?**
A) Install a sump pump in the basement
B) Regrade the soil to slope away from the foundation at a minimum slope of 6 inches over 10
feet
C) Apply waterproof coating to the interior basement walls
D) Install French drains around the perimeter
E) Recommend a structural engineer evaluate the foundation
***Correct Answer: B**
**Rationale:** Proper grading is fundamental to water management around a structure. The 6-
inch drop over 10 feet (approximately 5% slope) is the industry standard for directing surface
water away from foundations. While options A, C, and D are potential remediation measures,
correcting the grading addresses the root cause of water intrusion. Option E would be premature
without first addressing the grading issue. The inspector's priority must be to recommend
correction of the negative grade as the primary defense against foundation water damage.

**2. During a site inspection, you notice a retaining wall over 4 feet in height showing signs of
bowing and cracking. The wall appears to be constructed of dry-stacked stone without drainage
weepholes. What is the BEST course of action?**
,Page 3 of 128
A) Note the condition and recommend further evaluation by a qualified professional
B) Recommend installing drainage weepholes immediately
C) Note the wall as a cosmetic defect only
D) Recommend replacing the wall with a reinforced concrete wall
E) Document the condition but state it is outside the scope of inspection
***Correct Answer: A**
**Rationale:** Retaining walls over 4 feet in height are structural elements that require
professional engineering evaluation when showing signs of failure such as bowing or cracking.
The lack of drainage weepholes suggests hydrostatic pressure buildup, which is a common cause
of wall failure. Home inspectors must recognize their limitations and recommend specialized
evaluation rather than prescribing specific repairs. The inspector's role is to identify and report
defects, not to design solutions.

**3. Which of the following site conditions presents the GREATEST risk of structural damage to
a residential foundation?**
A) Trees planted within 15 feet of the foundation
B) Mulch placed against the siding
C) A driveway sloping at 2% away from the structure
D) Vegetation overgrowth on the roof
E) A walkway with minor settling
***Correct Answer: A**
, Page 4 of 128
**Rationale:** Trees planted too close to foundations pose significant risks through root
intrusion into foundation cracks and soil moisture depletion that can cause settlement. While
mulch against siding (B) creates moisture and pest issues, and vegetation on roofs (D) causes
damage, the structural threat from tree roots is more severe and costly. The driveway slope in
option C is actually correct (2% is appropriate for drainage). Minor settling in option E is
common and less concerning.
---
**4. A home inspector finds that the grade in a crawl space has exposed soil with standing water
in several areas. What is the PRIMARY concern?**
A) Increased radon entry potential
B) Wood rot and fungal growth on structural members
C) Pest infestation
D) Reduced energy efficiency
E) Musty odors in the living space
***Correct Answer: B**
**Rationale:** Standing water in a crawl space creates conditions for wood rot and fungal decay
of structural components, which directly threatens the integrity of the floor system. While
options A, C, D, and E are all legitimate concerns, the most critical immediate threat is structural
deterioration. Moisture management is fundamental to preserving the home's structural integrity,
and inspectors must identify conditions that promote rot in load-bearing members.

**5. Which of the following is the MINIMUM acceptable slope for a driveway to ensure proper
drainage away from a residential structure?**
