Domain 1: General Administration
Question 1 — Approved Construction Documents
During an inspection, the building inspector needs to verify that construction
matches the approved design. Which document is most important for this
purpose?
A. Contractor's personal notes
B. Manufacturer's advertising brochure
C. Approved construction plans
D. Previous inspection report
Answer: C. Approved construction plans
Rationale: Approved construction plans establish the design that has been
reviewed and authorized by the building department. Inspectors use them to
determine whether the work being constructed conforms to the approved project.
Question 2 — Permit Requirement
The primary purpose of a building permit is to:
A. Establish the contractor's profit margin
B. Authorize construction subject to applicable code requirements
,C. Guarantee that construction will never fail
D. Replace the approved construction drawings
Answer: B. Authorize construction subject to applicable code requirements
Rationale: A building permit provides legal authorization to perform regulated
construction and establishes the basis for required inspections and code
compliance.
Question 3 — Inspection Report
An inspection report should primarily:
A. Contain personal opinions about the contractor
B. Document observed conditions and applicable corrections
C. Replace the building permit
D. Approve uninspected work
Answer: B. Document observed conditions and applicable corrections
Rationale: Inspection reports provide an official record of observed construction
conditions, deficiencies, approvals, and required corrections.
Question 4 — Certificate of Occupancy
A certificate of occupancy generally indicates that:
A. The building has no maintenance requirements
B. The contractor has been paid in full
C. The building is authorized for occupancy under applicable requirements
D. Future inspections are unnecessary
Answer: C. The building is authorized for occupancy under applicable
requirements
Rationale: A certificate of occupancy is issued when the applicable requirements
for occupancy have been satisfied. It does not eliminate future maintenance
obligations or guarantee that no future inspections will occur.
,Question 5 — Plan Reading
A building inspector compares field construction with the approved plans
primarily to verify:
A. The contractor's accounting records
B. Conformance with the approved design
C. The property's market value
D. The project's advertising requirements
Answer: B. Conformance with the approved design
Rationale: Plan reading allows an inspector to identify dimensions, structural
components, materials, assemblies, and other requirements that should
correspond to the approved construction.
Domain 2: Building Planning
Question 6 — Occupancy Classification
Occupancy classification is important because it:
A. Determines the color of exterior paint
B. Helps establish applicable code requirements for the building's use
C. Determines the contractor's license fee
D. Eliminates structural design requirements
Answer: B. Helps establish applicable code requirements for the building's use
Rationale: Different uses create different levels and types of hazards. Occupancy
classification is therefore fundamental to determining requirements such as
construction type, fire protection, egress, and occupant load.
Question 7 — Construction Type
A building's construction type primarily describes:
, A. The property's ownership
B. The characteristics and combustibility of its structural elements and
assemblies
C. The number of employees
D. The building's plumbing fixtures
Answer: B. The characteristics and combustibility of its structural elements and
assemblies
Rationale: Construction type classifications distinguish buildings based on
characteristics such as structural fire resistance and combustibility of major
building elements.
Question 8 — Fire-Resistance Rating
A fire-resistance rating indicates the:
A. Maximum temperature of a building
B. Length of time a tested or approved assembly can perform its required fire-
resistance function
C. Number of fire extinguishers required
D. Weight of the building
Answer: B. Length of time a tested or approved assembly can perform its
required fire-resistance function
Rationale: Fire-resistance ratings are expressed in units of time and apply to
approved assemblies that have been evaluated for their ability to resist fire under
specified conditions.
Question 9 — Fire Separation
The primary purpose of a fire-resistance-rated separation is to:
A. Improve interior decoration
B. Limit the spread of fire between designated areas
C. Increase natural lighting
D. Reduce plumbing noise
