A multiple-use occupancy type is a structure with:

• A. two or more types of uses
• B. attached barns or carports
• C. multiple internal compartments
• D. multiple internal fire protection systems

Answer: (A)

The key idea is that a multiple-use occupancy is a building that supports more than one type of occupancy or activity. When a structure houses two or more uses—such as a retail store with offices upstairs, or residential units above a storefront—the fire and life-safety characteristics aren’t uniform throughout the building. This means different occupancy types may have different occupant loads, fire loads, required separation between uses, egress requirements, and fire protection considerations. Recognizing that there are two or more types of uses explains why such a building requires mixed planning and potentially multiple interventions during incidents.

The other options don’t define occupancy type. Attached barns or carports are physical features, not the concept of multiple uses within the structure. Multiple internal compartments describe internal layout, which can exist in single-use buildings as well. Multiple internal fire protection systems refer to safety measures, not to the occupancy classifications within the building.
