Means of egress shall be measured in units of exit width of 22 inches. 1. The maximum permitted occupant load of a space shall be determined by the capacity of the means of egress serving the space as calculated in accordance with Table 1. Building owners shall have the option of establishing a reasonable restriction on the occupant load of the space based on the existing capacity of the means of egress or of providing additional egress capacity. (Plan review--Building, Fire. Inspection--Building) i. Exception: For nightclubs, the occupant load of the space shall be determined in accordance with the building subcode. The occupant load for dance floors shall be calculated at seven square feet of floor area per occupant. (Plan review--Building, Fire. Inspection--Building) | Table 1 |
