The building regulation update focuses on three issues relevant to NSW builders and contractors: the release and phased adoption of NCC 2025, the Commonwealth’s NCC modernisation process, and the Federal Government’s pledge to remove paywalls on legislated Australian Standards.
NCC 2025 (final version) was published on 1 May 2026, following a preview release on 1 February 2026. Implementation dates vary by jurisdiction. For New South Wales, an adoption date of 1 May 2027, giving the industry a longer lead time than in several other states.
Master Builders’ NSW's position is that code reform must be predictable, well sequenced, and nationally consistent, with sufficient lead time for design changes, product evidence, training, and supply chain adjustments. The material also notes that some NCC 2025 provisions may commence at different times or not apply in full because of state and territory variations.
Treasury’s interim work on NCC modernisation identifies five broad reform directions: improving usability, restoring national consistency, strengthening governance and transparency, supporting innovation, and reducing the cost and complexity of demonstrating compliance. Treasury’s briefing to Master Builders described the review as a pro-productivity, pro-business reform, while acknowledging that the details of implementation will matter.
Master Builders NSW broadly supports the reform direction but is advocating for bigger structural change. Its comparative paper argues for plain-language drafting, better guidance material, stronger limits on state variations, more rigorous cost-benefit analysis, clearer innovation pathways, longer transition periods, and an independent statutory role for the Australian Building Codes Board (NCC).
Free Australian Standards
The Committee papers note that the Federal Government has committed to removing the paywall on all Australian Standards referenced in legislation, including standards referenced in the National Construction Code and work health and safety standards. This is a significant reform in usability and compliance for builders, particularly smaller firms that currently face substantial cost barriers to accessing standards.
Master Builders NSW is still confirming whether the commitment will also extend to standards referenced in safety codes of practice.

NCC transition periods and implementation risk
Continuous industry concern remains the speed and frequency of regulatory change. Treasury briefing recorded strong concern about inadequate transition periods for recent NCC changes, especially in Victoria, with risks including missing evidence of suitability, compliance uncertainty, and cost impacts flowing through to builders and consumers.
Master Builders NSW's draft policy position argues for clearly defined and mandatory transition periods for future code updates, and in related material, supports a minimum 12-month transition for major NCC changes. The same material also presses for more stable review cycles and stronger post-implementation evaluation using data from enforcement, audits, and compliance outcomes.
For NSW builders, the message is clear: use the additional time before 1 May 2027 to get ahead, not wait until the rules are enforced. Master Builders NSW stresses the importance of education on contract management and compliance with the NCC and its latest updates, especially regarding waterproofing and condensation, along with support for quicker building approvals for all developments, including minor variations and more efficient complying development pathways.
There is also a clear national push to reduce unnecessary variations across states and territories. The Treasury noted that national consistency should not override important local variations where they remain justified. That balance will matter in NSW, where members need a code framework that is simpler and more consistent nationally without losing practical settings that respond to local construction conditions.

- Prepare now for confirmed NCC 2025 changes affecting NCC Volume 2 Residential that include new condensation management requirements (vented wall cavities in cooler climate zones, vapour-permeable wraps, expanded roof ventilation), updated waterproofing provisions, and revised Performance Solution assessment methods — well before NSW's 1 May 2027 adoption date.
- If your business works on Class 2–9 projects, review the NCC 2025 changes to commercial energy efficiency (Section J — mandatory solar PV, higher envelope and services requirements for Class 3, 5–9), carpark fire safety (new sprinkler requirements), waterproofing and condensation provisions now, these changes are more extensive than those affecting Class 1 housing. They will require early engagement with designers, energy assessors, and fire engineers.
- Prepare which NCC-referenced Australian Standards are used most often in the business so teams can move quickly when the new free-access arrangements are clarified and implemented.
- Feed project-level issues back to MBA NSW, especially where transition periods, jurisdictional variations or compliance pathways are adding delay, uncertainty, or cost, so that current evidence informs ongoing advocacy.
