HABITABLE SPACE. A space in a building for living, sleeping, eating or cooking. Bathrooms, toilet rooms, closets, halls, storage or utility spaces and similar areas are not considered habitable spaces.
COMMENTARY; These spaces are normally considered inhabited in the course of residential living and provide the four basic characteristics associated with it: living, sleeping, eating and cooking. All habitable spaces are considered occupiable spaces, though other occupiable spaces, such as halls or utility rooms, are not considered habitable (see the definition of “Occupiable space” in this chapter).
OCCUPIABLE SPACE. A room or enclosed space designed for human occupancy in which individuals congregate for amusement, educational or similar purposes or in which occupants are engaged at labor, and which is equipped with means of egress and light and ventilation facilities meeting the requirements of this code.
COMMENTARY; Occupiable spaces are those areas designed for human occupancy. Based on the nature of the occupancy, various code sections apply. All habitable spaces are also considered occupiable (see the definition of “Habitable space”); however, all occupiable spaces are not habitable. Additionally, some spaces are neither habitable nor occupiable, such as closets, toilet rooms and mechanical equipment rooms.
All spaces are occupiable. The ones you listed have occupant load requirements in Chapter 10. Are you trying to get an occupant load or calculated areas?
