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.

The Australian Building Codes Board (ABCB) have released the second stage preview of NCC 2022.

NCC 2022 will be adopted by states and territories on 1 May 2023.

Noting the pressures experienced in recent times by the construction industry, Building Ministers have also agreed to transitional arrangements for the following specific requirements:

  • New livable housing requirements commence 1 October 2023
  • New energy efficiency and condensation mitigation requirements commence 1 October 2023
  • New lead-free plumbing product requirements commence 1 September 2025.

The transitional arrangements will allow practitioners to continue using the relevant provisions of NCC 2019 until the end of the relevant transition period.

NCC 2022 will be available from 1 October 2022, for those who wish to use the new provisions. This will also allow industry to adjust to the new requirements and structure prior to it becoming mandatory.

NCC Online will be updated to reflect the 2022 edition as of 1 October 2022, with PDFs of all volumes available for download from the ABCB’s website. Printed copies will also become available for purchase from the ABCB’s commercial providers.

Revised AS/NZS plumbing standards - Transition period extended

Following the recent announcement from Building Ministers to delay the adoption of NCC 2022, the VBA has extended the existing transition period for plumbers to familiarise themselves with revised AS/NZS standards, before they need to be applied to plumbing practices on 1 May 2023.

On 28 May 2021, Standards Australia published the following revised plumbing standards:

  1. AS/NZS 3500.1: 2021 Plumbing and Drainage Part 1: Water Services.
  2. AS/NZS 3500.2: 2021 Plumbing and Drainage Part 2: Sanitary Plumbing and Drainage.
  3. AS/NZS 3500.3: 2021 Plumbing and Drainage Part 3: Stormwater Drainage.
  4. AS/NZS 3500.4: 2021 Plumbing and Drainage Part 4: Heated Water.

The above standards are referenced in the Plumbing Regulations 2018 and/or the Plumbing Code of Australia 2019.

The revised standards will not be required to be used until 1 May 2023, which aligns with the commencement of the Plumbing Code of Australia 2022 edition. Between now and 1 May 2023, plumbing practitioners should continue to use AS/NZS 3500 Parts 1 to 4, the 2018 version.

From 1 May 2023, plumbing practitioners must use the 2021 versions of these standards.
