Risk management and client communication.
Introduction
, This practice test is designed to assess the knowledge, judgment, and field reasoning expected of a Maryland
home inspector candidate. It covers essential inspection concepts, defect recognition, reporting accuracy,
safety awareness, and professional conduct. The questions use multiple-choice and scenario-based formats to
reflect how inspectors apply principles in real situations. Emphasis is placed on identifying material defects,
understanding system performance, following legal and ethical standards, and making sound decisions
during a home inspection. The exam style encourages practical application rather than memorization alone.
Section One: Questions 1–100
. Which component is most directly used to support roof framing loads in a conventional attic?
A. Baseboard trim
B. Ceiling joists
C. Drywall screws
D. Window lintels
🟢 B. Ceiling joists
🔴 RATIONALE: Ceiling joists help support the ceiling and can tie building walls together while helping resist
roof thrust in conventional framing.
. A diagonal crack in a foundation wall is most likely to indicate:
A. Thermal expansion only
B. Structural movement
C. Normal paint shrinkage
D. Cosmetic settling of trim
🟢 B. Structural movement
🔴 RATIONALE: Diagonal cracking in foundation walls often suggests differential settlement or other
structural movement rather than a surface-only issue.
,. Which inspection finding most strongly suggests a roof leak has been active for some time?
A. Fresh nail heads on shingles
B. Dark staining on rafters and sheathing
C. Clean attic insulation
D. New drip edge flashing
🟢 B. Dark staining on rafters and sheathing
🔴 RATIONALE: Water staining on structural members often shows past or ongoing moisture intrusion over
time.
. The primary purpose of a vapor retarder is to:
A. Increase electrical capacity
B. Reduce moisture migration
C. Strengthen wall framing
D. Improve roof drainage
🟢 B. Reduce moisture migration
🔴 RATIONALE: Vapor retarders are used to slow moisture movement through building assemblies and help
limit condensation problems.
. A GFCI is designed mainly to reduce the risk of:
A. Overheating conductors
B. Lightning strikes
C. Electric shock
D. Low voltage
🟢 C. Electric shock
🔴 RATIONALE: Ground-fault circuit interrupters trip when they detect leakage current, helping protect
people from shock hazards.
, . Which of the following is most likely a major defect requiring immediate attention?
A. Slight paint wear on a handrail
B. Loose stair tread with visible movement
C. Minor dust in an HVAC vent
D. Small scratch on a window pane
🟢 B. Loose stair tread with visible movement
🔴 RATIONALE: A loose tread is a safety hazard that can cause injury and should be reported as a significant
defect.
. In a home inspection, the attic is inspected primarily to evaluate:
A. Interior décor quality
B. Structural, insulation, and ventilation conditions
C. Carpet wear
D. Appliance brand names
🟢 B. Structural, insulation, and ventilation conditions
🔴 RATIONALE: The attic provides access to key components affecting structure, energy performance, and
moisture management.
. Which condition is most likely to contribute to mold growth?
A. Dry lumber
B. Excess moisture
C. Proper airflow
D. Stable temperature
🟢 B. Excess moisture
🔴 RATIONALE: Mold growth requires moisture; controlling water intrusion and humidity is essential for
prevention.
