What is the purpose of the Occupant Load Factor table in the Life Safety Code?

The occupant load factor table ties space function to how many people a space can safely hold by giving a square footage allowance per person for each use. The main idea is to determine the maximum number of occupants allowed in a space based on its use, so that egress design can be planned accordingly. You calculate the occupant load by dividing the floor area by the factor for that use, and that number then informs requirements like exit capacity, door widths, and travel distances to ensure safe evacuation. For example, a 2,000 square foot room used as a lecture hall with an occupant load factor of 15 square feet per person would yield about 133 occupants (2,000 ÷ 15). This shows how the table directly supports safe occupancy limits and the corresponding life-safety design requirements. It’s not about specifying the exact number of exits by itself, nor about calculating or determining total building area or gross floor area.
