What are Australian building standards for new homes?

National Construction Code

The National Construction Code (NCC) sets minimum standards for the design and construction of new residential buildings, apartments and commercial buildings. The Building Code of Australia is a component of the National Construction Code.

The NCC is performance-based and specifies how the building must perform. The Australian Building Codes Board is responsible for producing and maintaining Australia’s national building code on behalf of the federal and state government. It ensures there is consistency in the construction standards throughout Australia. The requirements of the NCC can be met by using Performance Solution, Deemed-to-Satisfy Solution or a combination of both.

Performance Solution encourages the use of innovative designs and technology to comply with the NCC.

Deemed-to-Satisfy (DNS) Solution includes a step-by-step process, i.e. which materials and construction methods need to be used. They reference the Australian Standards and include detailed information on different construction elements.
