SECTION 1002 - OCCUPANT LOAD

1002.1 Determination of Occupant Load.

1002.1.1 Areas to be included. In determining the occupant load, all portions of a building shall be presumed to be occupied at the same time.

EXCEPTION: Accessory use areas which ordinarily are used only by persons who occupy the main areas of an occupancy shall be provided with exits as though they are completely occupied, but their occupant load need not be included in computing the total occupant load of the building.

The occupant load for a building shall be determined in accordance with the provisions of this section.

1002.1.2 General. For areas without fixed seats, the occupant load shall not be less than the number determined by dividing the floor area assigned to that use by the occupant load factor set forth in Table 10-A. Where an intended use is not listed in Table 10-A, the building official shall establish an occupant load factor based on a listed use which most nearly resembles the intended use.

For a building or portion thereof which has more than one use, the occupant load shall be determined by the use which gives the largest number of persons.

The occupant load for buildings or areas containing two or more occupancies shall be determined by adding the occupant loads of the various use areas as computed in accordance with the applicable provisions of this section.

1002.1.3 Fixed seating. For areas having fixed seats and aisles, the occupant load shall be determined by the number of fixed seats installed therein. The required width of aisles serving fixed seats shall not be used for any other purpose.

For areas having fixed benches or pews, the occupant load shall not be less than the number of seats based on one person for each 18 inches (457 mm) of length of pew or bench.

Where booths are used in dining areas, the occupant load shall be based on one person for each 24 inches (610 mm) of booth length or major portion thereof.

1002.1.4 Reviewing stands, grandstands and bleachers. The occupant load for reviewing stands, grandstands and bleachers shall be calculated in accordance with this section and the specific requirements contained in Section 1021.

1002.2 Maximum Occupant Load.

1002.2.1 Assembly occupancies. The maximum occupant load for assembly occupancies shall not exceed the occupant load determined in accordance with Section 1002.1.

EXCEPTION: When approved by the building official, the occupant load for an assembly occupancy may be increased provided the maximum occupant load served does not exceed the capacity of the exit system for such increased number of persons. The building official may require an aisle, seating or fixed equipment diagram to substantiate such an increase, and may require that such diagram be posted.

1002.2.2 Other occupancies. For other than assembly occupancies, an occupant load greater than that determined in accordance with Section 1002.1 is permitted; however, the exit system shall comply with the provisions of this chapter for such increased number of persons.

1002.3 Posting of Room Capacity. Any room having an occupant load of 50 or more where fixed seats are not installed, and which is used for assembly purpose, shall have the capacity of the room posted in a conspicuous place on an approved sign near the main exit from the room. Such signs shall be maintained legible by the owner or the owner's authorized agent and shall indicate the number of occupants permitted for each room use.

1002.4 Revised Occupant Load. After a building is occupied, any change in use or increase in occupant load shall comply with this chapter. See Section 3405.
