How this is calculated
Occupant load = floor area ÷ occupant load factor for the space's function (IBC Table 1004.5), rounded up to the next whole number. The factor and whether to use gross or net area depend on the space's function, not the building's occupancy classification. For details, see our occupant load guide and occupant load factors by occupancy guide.
This calculator uses model IBC factors for general reference. It is not a substitute for the adopted code and amendments enforced by your local authority having jurisdiction. Always verify against the edition and amendments your jurisdiction has adopted.
