In New South Wales, houses, sheds and decks (Class 1 and Class 10) are still built to **NCC 2022**. NSW has put NCC 2025 back. It’s now **set to start from 1 May 2027**. So every job you’re quoting or setting out today runs to NCC 2022. There’s no choice of edition on site — you work from one rule book. Use that to get the basics right. Our [NCC-for-chippies stairs pillar](https://www.chippy.tools/building-codes/au/ncc-for-chippies/) covers the riser, going and rail numbers that decide a pass or fail, and the [concrete calculations guide](https://www.chippy.tools/building-codes/concrete/concrete-calculations-guide/) helps you order the right amount for slabs, footings and pads. ## Adoption status Announced Current code in force NCC 2022 Next edition NCC 2025 (from 1 May 2027) Adoption / transition NSW deferred NCC 2025 to 1 May 2027 — build to NCC 2022 until then.
