Required facilities for Class 1 buildings

This information has been prepared to explain the requirements for private amenities and facilities in all Class 1 buildings as set out in NCC Volume Two Housing Provisions.

Definition of Class 1a and 1b buildings

This information has been prepared to explain the requirements for private amenities and facilities in all Class 1 buildings as set out in NCC Volume Two Housing Provisions.

The NCC defines Class 1 buildings as either Class 1a or Class 1b as follows:

  • Class 1a – a single dwelling being a detached house or one of a group of two or more attached dwellings, each being a building separated by a fire-resisting wall, including a row house, terrace house, town house or villa unit, and
  • Class 1b – a boarding house, guest house, hostel and the like with a total area of all floors not exceeding 300m2 measured over the enclosing walls and in which not more than 12 persons would ordinarily be resident, which is not located above or below another dwelling or another class of building other than a private garage.

All Class 1a and 1b buildings must be provided with the following private amenities and facilities:

  • A kitchen sink and facilities for the preparation and cooking of food, and
  • A bath or shower, and
  • Clothes washing facilities, comprising of at least one washtub and space in the same room for a washing machine, and
  • A closet pan and washbasin.

If any of the above facilities are detached from the main building, they must be set aside for the exclusive use of the occupants of the building.

Construction of sanitary compartments

The NCC sets out detailed requirements for the design of sanitary compartments (toilets).

The door to a fully enclosed sanitary compartment (room or space containing a closet pan or urinal) must:

  • open outwards, or
  • slide, or
  • be readily removable from the outside of a compartment, unless there is a clear space of at least 1.2m between the closet pan within the sanitary compartment and the nearest part of the doorway.

This requirement provides a means of removing an unconscious occupant from a fully enclosed sanitary compartment. If the enclosure has gaps that are large enough to allow access for a person into the sanitary compartment, the compartment is not considered enclosed for the purpose of the above requirements.

More detailed information is available in Part 3.8.3 Facilities of the NCC and in the HIA Guide to Kitchen & Bathroom Construction [LINK TO: https://hia.com.au/Shop/HIA-Products/g_kbcg---guide-to-kitchen-bathroom-construction-edition-2/kbcg---guide-to-kitchen-bathroom-construction-edition-2], which has clear illustrations on how to comply with the NCC requirements on the construction of sanitary compartments.
