Florida Home Inspector Exam 2026 – 190 Practice Questions with
Answers & Detailed Rationales, Structural, Electrical, HVAC,
Roofing, Plumbing, Interior, Exterior & Site Conditions
Questions 1–24: Structural Systems
Question 1
During an inspection of a two-story residence in Tampa, you observe stair risers that vary in
height by approximately 1.5 inches. What is the most appropriate observation?
A. The variation is acceptable if handrails are present on both sides.
B. The variation is acceptable in homes constructed before 2000.
C. The variation may present a safety hazard due to inconsistent stair geometry.
D. The variation is only a cosmetic concern requiring no comment.
Correct Answer: C
Explanation: Inconsistent riser heights disrupt the user's walking rhythm, increasing trip-and-
fall risk. Report as a safety concern regardless of code enforcement scope.
Question 2
A home inspector observes efflorescence on a basement masonry wall in a Tallahassee
home. What does this most strongly indicate?
A. Structural failure of the foundation requiring immediate evacuation.
B. Moisture migration through masonry materials.
C. Presence of asbestos-containing materials in the mortar.
,D. Excessive radon levels requiring mitigation.
Correct Answer: B
Explanation: Efflorescence is the white crystalline residue left when water moves through
masonry and evaporates. It indicates moisture intrusion, not necessarily structural failure.
Question 3
When inspecting a crawlspace, you observe extensive fungal growth on floor joists covering
approximately 40% of their surface area. What should be reported?
A. Only the cosmetic appearance in the report.
B. The estimated replacement cost for all affected joists.
C. Evidence of conditions conducive to wood deterioration and recommendation for further
evaluation.
D. Immediate condemnation of the structure.
Correct Answer: C
Explanation: Fungal growth indicates elevated moisture that can lead to decay. Inspectors
should identify the condition, its implications, and recommend evaluation.
Question 4
A home inspector in Orlando observes a horizontal crack in a poured concrete foundation
wall that is 1/4 inch wide and runs the full length of the wall. What does this most likely
indicate?
A. Normal curing shrinkage that requires no comment.
,B. Potential structural movement or lateral soil pressure requiring further evaluation.
C. Improper concrete mix that voids all warranties.
D. A cosmetic defect that can be filled with caulk.
Correct Answer: B
Explanation: Horizontal cracks in foundation walls often indicate lateral soil pressure or
structural movement, which can compromise foundation integrity and require professional
evaluation.
Question 5
During an inspection of a wood-frame home, you observe that a floor joist has been notched
at its center span to a depth exceeding one-third of its depth. What is the primary concern?
A. The notch may reduce the joist's load-carrying capacity.
B. The notch improves ventilation in the floor cavity.
C. The notch is acceptable if the joist is pressure-treated.
D. The notch is required for plumbing installations.
Correct Answer: A
Explanation: Notches in the middle third of a joist's span significantly weaken its structural
capacity. The middle third is subject to the highest bending stress.
Question 6
A home inspector observes diagonal cracks above door frames and window openings in a
brick veneer wall. These cracks are staircase-shaped and follow the mortar joints. What is
the most likely cause?
, A. Thermal expansion of the brick veneer.
B. Differential settlement of the foundation.
C. Improper flashing installation at the openings.
D. Normal aging of the mortar joints.
Correct Answer: B
Explanation: Staircase cracking following mortar joints is characteristic of differential
settlement or movement in the foundation or structural frame.
Question 7
When inspecting an attic, you observe that a roof rafter has been cut to accommodate a new
HVAC duct and the cut rafter is no longer connected. What should be recommended?
A. No action is needed if the cut is less than 2 inches.
B. Immediate evaluation by a structural professional.
C. Painting the cut end to prevent moisture damage.
D. Installing additional insulation around the cut.
Correct Answer: B
Explanation: A cut structural rafter compromises the roof's load-bearing capacity. A
structural professional must evaluate and design appropriate repairs.
