Occupancy Load Calculator
Enter the area and pick the use classification — this tool applies the IBC Table 1004.5 occupant-load factor to compute the design occupant load. Use the total to size egress width, exit count, restrooms, and sprinkler coverage.
Occupancy load
Code cited: IBC 2021 Table 1004.5 — Maximum Floor Area Allowances per Occupant. Occupant load is used in §1005 (egress width), §1006 (exit count), and drives sprinkler-classification and plumbing-fixture counts elsewhere in the IBC.
