1.
A building official receives construction documents for a new commercial
building. The drawings appear complete, but the applicant has not identified the
applicable construction type or occupancy classification. What should the building
official do first?
A. Approve the plans and allow the contractor to determine the classification in
the field
B. Require the applicant to establish the applicable occupancy and construction
classifications before completing the code review
C. Assign the most restrictive occupancy automatically
D. Refer the entire application to the fire department without further review
,Answer: Require the applicant to establish the applicable occupancy and
construction classifications before completing the code review
Rationale: Accurate occupancy and construction classifications are fundamental
to determining allowable area, height, construction requirements, fire-
resistance ratings, egress requirements, and other applicable provisions. A
building official should not complete a substantive code review using unresolved
classifications.
2.
During plan review, the building official determines that the proposed use is
classified differently from the classification stated by the design professional.
Which approach is most appropriate?
A. Ignore the discrepancy because the architect signed the drawings
B. Automatically deny the application
C. Document the discrepancy and require clarification or correction based on the
applicable code provisions
D. Allow the contractor to select the classification
Answer: Document the discrepancy and require clarification or correction based
on the applicable code provisions
Rationale: The building official is responsible for administering the adopted
code, while the design professional is responsible for preparing compliant
construction documents. Classification conflicts should be resolved through
documented code analysis rather than assumption.
3.
A permit applicant proposes a building that technically complies with a
prescriptive requirement but presents an unusual design not specifically
described in the code. What is the best administrative response?
A. Reject all designs not expressly illustrated in the code
B. Require the applicant to redesign the building using only familiar construction
,methods
C. Evaluate the proposed alternative under the code's provisions for approved or
alternative methods where applicable
D. Approve the design without documentation
Answer: Evaluate the proposed alternative under the code's provisions for
approved or alternative methods where applicable
Rationale: Building codes generally establish minimum performance and safety
requirements and may permit approved alternatives when equivalent safety,
strength, durability, fire protection, or sanitation is demonstrated.
4.
Why is the determination of occupant load particularly important during plan
review?
A. It determines only the number of parking spaces
B. It affects egress capacity, number and arrangement of exits, plumbing fixture
calculations, and related life-safety provisions
C. It determines the contractor's license classification
D. It determines the property's assessed value
Answer: It affects egress capacity, number and arrangement of exits, plumbing
fixture calculations, and related life-safety provisions
Rationale: Occupant load is a foundational life-safety calculation. It influences
egress width and capacity, exit requirements, plumbing fixture counts, and
other code provisions.
5.
A contractor begins foundation work before obtaining a required building permit.
What is the building official's primary concern?
A. Whether the contractor has purchased insurance
B. Whether the work was authorized and whether enforcement action is required
under applicable law
, C. Whether the owner has selected interior finishes
D. Whether the project will be completed early
Answer: Whether the work was authorized and whether enforcement action is
required under applicable law
Rationale: Beginning regulated construction without the required permit is an
administrative and enforcement issue. The building official should follow the
jurisdiction's established procedures for stop-work orders, permits, penalties,
inspections, or other remedies.
6.
A stop-work order is issued because construction is proceeding contrary to
approved documents. The contractor continues working. What is the most
appropriate response?
A. Ignore the violation until final inspection
B. Remove the contractor from the project personally
C. Follow the jurisdiction's enforcement procedures and document continued
noncompliance
D. Approve the work because it has already been installed
Answer: Follow the jurisdiction's enforcement procedures and document
continued noncompliance
Rationale: Enforcement must be consistent, documented, and based on the
authority granted by law. A building official should use established
administrative and legal procedures rather than acting outside that authority.
7.
Which document generally provides the clearest indication of the intended scope
of permitted construction?
A. Contractor's verbal statement
B. Approved construction documents and permit
