NCC 2025 Commencement

We wish to update you that on October 22, 2025, the Commonwealth, State and Territory Building Ministers met and confirmed that the NCC 2025 content has been finalised and will be published on February 1, 2026.

The earliest adoption date will be May 1, 2026. However, it is up to each State and Territory to announce its own adoption date. It is expected that some States might delay the commencement further, but no official announcement has been made regarding this. PCG will provide updates on the commencement dates as we receive them.

The Ministers agreed to the following necessary adjustments for inclusion in NCC 2025:

• Water management in commercial and apartment buildings to prevent water ingress,
• Carpark fire safety provisions for commercial and apartment buildings,
• Commercial energy efficiency reforms, including efficiency improvements and mandatory on-site solar photovoltaic systems to support net zero ambitions, and
• Condensation mitigation.

NCC 2029

The Building Ministers also discussed that no further residential changes will be made to the NCC, except for essential quality and safety measures, until mid-2029. There has been no confirmation on the details of what might be contained within NCC 2029, as it is too far away.
