Per § 1006.3, the means of egress system serving any story or occupied roof is to be provided with the number of exits based on the aggregate occupant load served. But, where stairways serve more than one story, only the occupant load of each story considered individually need be used in calculating the required number of exits or access to exits serving that story.

Per § 1006.3.1, the path of egress travel to an exit may not pass through more than one adjacent story.

Per exceptions noted in § 1006.3.1,, the path of egress travel to an exit is permitted to pass through more than one adjacent story in the following cases:

In Group R-1, R-2, or R-3 occupancies, exit access stairways and ramps connecting four stories or less within an individual unit.

Exit access stairways within a Group R-3 congregate residence or a Group R-4 facility.

Exit access stairways and ramps in open parking garages that serve only the parking garage.

Exist access stairways and ramps serving open-air assembly seating complying with the exit access travel distance requirements of § 1029.7.

Exit access stairways and ramps between the balcony, gallery, or press box and the main assembly floor in occupancies such as theaters, places of religious worship, auditoriums, and sports facilities.
