National Construction Code

The National Construction Code (NCC) is a set of minimum requirements for buildings in Australia. The requirements concern the aspects of health, safety, accessibility, amenity and sustainability of the types of buildings that the code applies to. The Code is published by the Australian Building Codes Board (ABCB) in service to the Australian Federal Government as well as State and Territorial governments of Australia.

The NCC 2022 replaced the NCC 2019; it is revised every 3 years. The NCC consists of 3 volumes. Volume One contains requirements for mostly commercial buildings, Volume Two contains requirements for mostly domestic buildings. These first two volumes together are known as the Building Code of Australia (BCA). Volume Three contains plumbing and drainage requirements for all types of buildings, it is also known as the Plumbing Code of Australia.
