What term describes the use of all or a portion of a building or structure?

• A. Occupancy classification
• B. Building type
• C. Fire resistance rating
• D. Construction type

Answer: (A)

Occupancy classification describes how a space within a building is used, whether the whole building or a portion. This classification drives the fire code requirements that apply to that space, such as occupant load, means of egress, fire protection systems, and separation needs based on the intended use. The other terms refer to physical attributes rather than what the space is used for: building type groups construction approaches, fire resistance rating measures how long elements resist fire, and construction type covers the materials and assemblies used. So, describing the use of all or part of a building aligns directly with occupancy classification.
