New South Wales delays its uptake of the National Construction Code 2025 by 12 months, giving builders, designers and developers time to adapt without derailing housing delivery.

Architects, builders and developers working across NSW will have until 1 May 2027 to comply with the new National Construction Code (NCC), after the NSW Government announced a 12-month transition period beyond the national adoption date of 1 May 2026, a decision designed to protect the state’s momentum on housing delivery without sacrificing the intent of the updated standards.

The NCC is Australia’s foundational framework for building standards, encompassing health, safety, amenity and sustainability requirements across residential and commercial construction. Published by the Australian Building Codes Board (ABCB) in partnership with federal, state and territory governments, NCC 2025 introduces new provisions for the commercial sector alongside targeted quality and safety improvements for residential building.

NSW Minister for Building, Anoulack Chanthivong, framed the decision as a pragmatic response to the pressures facing the state’s construction sector. “We are working in lockstep with the construction industry to ensure these homes are high-quality, safe and sustainable,” he said. “The NCC 2025 represents sensible and reasonable steps towards that goal.”

A considered set of NSW variations

Beyond the extended timeline, the NSW Government has signalled it will introduce a series of state-specific variations to the NCC 2025, a move aimed at reconciling the new national provisions with existing state legislation, technical building requirements, and plumbing and drainage standards applicable in NSW.

Among the most significant variations is a provision allowing apartment building owners undertaking remedial works to choose between waterproofing requirements set out in either the current NCC or the incoming NCC 2025. The flexibility is intended to keep remediation costs manageable for homeowners navigating what can already be a financially burdensome process.

Notably, the new energy efficiency standards introduced under NCC 2025 will not apply to the common areas of apartment buildings in NSW, a carve-out that will be watched closely by sustainability advocates and designers who have long pushed for more ambitious performance requirements across the built environment.

Minimising disruption, managing compliance risk

The Minns Labor Government’s rationale for the extended adoption period extends beyond simple industry convenience. The 12-month window is also intended to reduce future compliance risk for projects set to commence in early 2027, giving design and construction teams the opportunity to plan ahead and embed the new requirements into their project pipelines before they become mandatory.

“We want to make sure this does not cause disruption to the construction sector’s ability to deliver homes and meet housing demand in NSW,” Chanthivong said. “This transition period will also minimise future compliance risk by allowing industry to plan for the changes in the NCC 2025 and factor them into their new projects ahead of time.”

A preview version of the NCC 2025 is currently available through the ABCB, with the full suite to be published on 1 May 2026. NSW’s specific variations will be detailed at the same time, giving the industry a clear, consolidated picture of what compliance will look like across the state from May 2027.
