Under the revised approach, NCC 2025 will become mandatory from 1 May 2027, with a 12-month transition period commencing from 1 May 2026. During this time, projects can be assessed under either NCC 2022 or NCC 2025.
“The decision to extend the transition period from the originally proposed six months to twelve months was a sensible and pragmatic outcome”, said HIA Executive Director ACT & Southern NSW, Geordan Murray.
“HIA has consistently advocated for a transition period of at least 12 months, recognising the scale and complexity of the changes contained in the updated code.
“This will give the ACT building industry the best chance of a smooth transition to NCC 2025.
“Aligning the ACT’s transition timeframe with New South Wales is particularly important given the integrated nature of the region’s building industry.
“The industry in the ACT and the Capital Region of NSW operate as a combined economic region, with builders, designers and trades regularly working across the border.
“Having the ACT in alignment with NSW reduces unnecessary complexity and is one less consideration for businesses dealing with different regulatory settings on either side of the border.
The ACT Government has also confirmed that projects which are well advanced — with key applications lodged before 1 November 2026 — will have flexibility to proceed under either NCC 2022 or NCC 2025.
“This additional flexibility is critical,” Mr Murray said.
“It ensures that projects already in the pipeline are not forced into costly redesign late in the process, which can delay delivery and add further pressure to housing supply.
“With the transition period now settled, the focus must shift to bringing industry up to speed on the practical, on-site implications of NCC 2025 — ensuring builders and trades are equipped to implement the changes, and that certifiers are aligned with industry on how the new requirements will be interpreted and assessed in practice.
“HIA will continue to work with the ACT Government to ensure the implementation of NCC 2025 is practical, well sequenced, and supports the delivery of new housing at a time when it is urgently needed,” Mr Murray concluded.
