National Construction Code (NCC) 2022

The National Construction Code (NCC) sets out the requirements for the design and construction of buildings in Australia, including plumbing and drainage work. It sets the minimum required level for the safety, health, amenity, accessibility and sustainability of certain buildings.

  • Volume One: relates to Class 2 to 9 buildings.
  • Volume Two: relates to Class 1 and 10 buildings.
  • Volume Three: relates to plumbing and drainage work associated with all classes of buildings (see Plumbing Codes and Standards for more information).

The Australian Building Codes Board (ABCB) released NCC 2022 on 1 October 2022 to allow industry time to adjust to the new requirements and structure prior to it becoming mandatory. PDFs of all volumes are available for download. Printed copies will also become available for purchase from the ABCB’s commercial providers .

Energy efficiency and condensation mitigation requirements

The ABCB has updated the NCC to strengthen minimum requirements for the energy efficiency of new homes. The new energy efficiency and condensation mitigation requirements will commence in Victoria on 1 May 2024.

The changes will make homes cheaper to run, more comfortable to live in and more resilient to extreme weather.

Victoria will also remove barriers to installation of efficient electric hot water systems, helping households to capture further benefits from investing in solar panels, and supporting those who choose all-electric new homes.

Learn more about 7 star energy efficiency building standards by heading to the Department of Energy, Environment and Climate Action (DEECA) energy website.

Learn more by accessing updated energy efficiency Practice Notes.

Livable housing design requirements

NCC 2022 includes new requirements for livable housing design.

These new provisions will improve the suitability of new Australian homes for people with mobility constraints.

The Livable Housing Standard is a significant advance in providing more housing options for people with physical disabilities and older Australians and will apply to new houses and apartments.

Head to the ABCB website to learn more about these changes.

Work underway to amend the Building Regulations 2018 to reflect adoption of BCA 2022

The Building Regulations 2018 (Regulations) contain a number of clause references to the Building Code of Australia (BCA) 2019. We are working with the Department of Transport and Planning to update the Regulations with new references to the BCA 2022 that came into effect on 1 May 2023.

In the interim, building work that fulfills the technical solution requirements of BCA 2022 as below will be deemed to be compliant.
