Plan Review drawings are used to indicate:

• A. Occupancy classification
• B. Fire resistance ratings
• C. Structural steel size
• D. Electrical load

Answer: (A)

The main idea is how the space will be used. Plan review drawings indicate the occupancy classification because the intended use of the building (assembly, business, education, etc.) determines which code requirements apply—things like means of egress, occupant load, separation between spaces, and required fire protection features. Other items—fire resistance ratings, structural steel sizes, and electrical loads—are governed by separate design documents and calculations (construction details, structural drawings, and electrical plans), not by the occupancy classification shown on plan review drawings. Therefore, occupancy classification is what plan review drawings convey to guide code compliance.
