What is the primary method used to determine occupant load?

• A. Floor Area
• B. Aisle Width
• C. Occupancy Classification
• D. Building Exit

Answer: (A)

Determining occupant load starts with the space’s floor area and an occupant load factor tied to the specific use. The basic calculation is floor area divided by the appropriate occupant load factor for that occupancy. This is why floor area is the primary method—the size of the space sets how many people can fit, and the load factor converts that space into a people count. The occupancy classification tells you which load factor to use, but the actual count comes from applying the factor to the floor area. Aisle width and building exits influence egress design and safety requirements, not the basic occupant count derived from space size. For example, a 2,000 square-foot space with an assembly load factor of 7 square feet per person yields about 286 occupants.
