What term is the categorization of buildings based on use?

• A. Dwelling Unit
• B. Building Construction and Safety Code
• C. Occupancy Classification
• D. Grade Plane

Answer: (C)

Occupancy classification is the term used for grouping buildings by how they are used. This grouping directly affects fire protection design because different uses create different fire hazards, occupant densities, egress needs, and safety considerations. In NFPA 13R for low-rise residential systems, knowing the occupancy helps determine appropriate sprinkler design criteria, such as required water density and system features, to address the specific risks of that use. The other terms don’t describe categorizing buildings by use: a dwelling unit is a living space within a building, a building construction and safety code is the overall code framework, and grade plane is a ground reference used for design purposes.
