National Construction Code
The National Construction Code (NCC) provides the minimum necessary requirements for safety and health; amenity and accessibility, and sustainability in the design, construction, performance and livability of new buildings (and new building work in existing buildings) throughout Australia. It is a uniform set of technical provisions for building work and plumbing and drainage installations throughout Australia whilst allowing for variations in climate and geological or geographic conditions.
The NCC is an initiative of the Council of Australian Governments (COAG) developed to incorporate all on-site construction requirements into a single code. The NCC is comprised of the Building Code of Australia (BCA), Volume One and Two; and the Plumbing Code of Australia (PCA), Volume Three.
NCC Volume One primarily applies to Class 2 to 9 (multi-residential, commercial, industrial and public) buildings and structures.
NCC Volume Two primarily applies to Class 1 (residential) and 10 (non-habitable) buildings and structures.
NCC Volume Three applies to plumbing and drainage for all classes of buildings.
Administration of the NCC is the responsibility of the States and Territories under their various building and plumbing Acts and Regulations. State and Territory Acts and Regulations set out the legal framework to support the design and construction of buildings. Regulations and Acts contain amongst other things, the requirements relating to building and occupancy permits, building inspections, and enforcement of the regulations. In most cases, certain powers under these Acts and Regulations have been delegated to either local government authorities or private sector building certifiers, including the power to issue approvals, licences or permits for building work. These administering authorities are responsible for determining whether a building or plumbing work complies with the BCA or PCA in the first instance.
