Calculating Occupant Load. In order to calculate the occupant load within an area of a building correctly, the code establishes two methods: (1) Areas without Fixed Seating - (Section 1004.1.2) (2) Areas with Fixed Seating - (Section 1004.4) Let us take a look at how the occupant load is calculated using each method The occupancy load is calculated by dividing the area of a room by its prescribed unit of area per person. Units of area per person for specific buildings can be found in the chart at the end of this article. For instance, the chart dictates that dormitories require 50 square feet of floor area for every room occupant
The occupant load can be increased in accordance with 1004.2, but cannot be less than the prescriptive calculated occupant load.
