If the number of people who will occupy a building is known, it should be used. However, in the absence of more accurate information, Clause D1.13 must be used. D1.13 is used in several Parts of the BCA, such as in calculating minimum exit widths, as well as the number of sanitary and other facilities. D1.13 does not restrict the number of occupants using a building, or enforce any building use or licensing requirements.

Part F3 of the BCA details the requirements for rooms or spaces within a building that must provide a height suitable for the intended use. ‘Intended use’ recognises that the height required in rooms and spaces is directly related to the room’s function.

The BCA classifies buildings by their use. A building may be made up of a number of classes if it has a mixed use.

Clause D3.4 details exemptions to the requirements for access to certain areas within buildings where providing access would be inappropriate because of the nature of the area or the tasks undertaken.
