To determine the required number of fixtures, the fixture ratio or ratios for each fixture type shall be applied to the occupant load of each sex in accordance with Table 2902.1 Alternatively, the maximum occupant load in a room may be calculated from Chapter 10 of the CBC. To determine the occupant load, divide the floor area of the use by the appropriate occupant load factor listed in CBC Table 1004.5 and Technical Bulletin 10-1, which provide the maximum floor area per occupant based upon usage. Example: A retail. shall be computed with the occupant load factor associated with Unconstrained Assembly without Fixed Seats as identified in CBC table 1004.1.2. The number of occupants for Traditional Educational Laboratory spaces shall be computed at no less than 50 sqft net per person To determine the occupant load of a space, divide the size of the space by the occupant load factors. In many assembly settings, there will be more than one use. The following is an example of an assembly venue with multiple uses. The occupant load is determined by measuring the areas, dividing by the occupant load factors for each area The occupant load permitted in any building, or portion thereof, is permitted to be increased from that number established for the occupancies in Table 1004.5, provided that all other requirements of the code are met based on such modified number and the occupant load does not exceed one occupant per 7 square feet (0.65 m2) of occupiable floor.

In a Group I-2 occupancy, the California Building Code (CBC) permits waiting (seating) in lobbies, foyers and reception areas when these areas are constructed as required for corridors, protected by automatic fire detection, quick-response automatic sprinklers and located so as to permit direct visual supervision by the facility staff Many code requirements are dependent upon the occupant load of the room or space in question. For example, the International Building Code (IBC) requires panic hardware for doors equipped with a lock or latch, which serve assembly or educational occupancies with an occupant load of 50 or more (the occupant load limit for NFPA 101 - The Life Safety Code is 100 or more)
