how must each occupancy in a building be separated?
occupancies must be separated with a fire barrier of the hourly rating defined by code.
what is accessory occupancy?
a space ancillary to the main occupancy, not exceeding 10% of the floor area.
what is an incidental use occupancy?
a space ancillary to the main occupancy with the same occupancy classification as the nearest main occupancy, but poses a greater risk.
