The rollout of the National Construction Code 2025 (NCC 2025) in Victoria is set to reshape how building standards are applied across the state.
A shift in building and plumbing standards
According to Monash University Department of Civil and Environmental Engineering’s Dr Mehrdad Arashpour, one of the most significant changes is the immediate move toward safer materials in critical systems.
“The introduction of NCC 2025 in Victoria marks a shift in how building and plumbing standards are applied, particularly with the immediate move to lead-free requirements in drinking water systems,” he said.

This change is expected to have a direct impact on public health outcomes, while also requiring suppliers and contractors to adapt quickly to updated material standards.
Greater national consistency
The update also brings Victoria more in line with national regulations, simplifying requirements for industry operating across multiple states.
“The removal of redundant Victorian variations brings the state closer to national consistency, which should reduce complexity for industry, while still retaining important local provisions such as expert judgement for structural and fire safety solutions,” Dr Arashpour said.
For builders, engineers and contractors, this alignment is likely to reduce administrative burden while maintaining flexibility where it matters most.
Streamlining compliance
Changes to how requirements are structured within the code are also aimed at making compliance more straightforward.
“Updates to children’s services requirements and the relocation of technical provisions into the NCC are also expected to streamline compliance and reduce regulatory burden, but will require industry to quickly adapt to a new framework.”
While the long-term goal is simplification, the transition period will demand close attention from industry to ensure compliance with the updated framework.
Implications for the built environment
More broadly, the rollout reflects a continued push toward improving building outcomes across safety, sustainability and performance.
“Overall, these changes signal a continued move toward harmonisation and modernisation of Australia’s building standards, with important implications for safety, sustainability and construction practice across Victoria,” Dr Arashpour added.
As NCC 2025 comes into effect, the focus will be on how quickly industry can adapt — and how effectively these changes translate into safer, more consistent building outcomes across Victoria.
