In Queensland, houses, sheds and decks (Class 1 and Class 10) are still built to **NCC 2022**. The state has put NCC 2025 back. It’s now **set to start from 1 May 2027**. So for every job you’re pricing or setting out today, NCC 2022 is the edition you follow. There’s no choice of edition to make here yet, which keeps things simple on site. Use that to lock in the basics. Our [NCC-for-chippies stairs pillar](https://www.chippy.tools/building-codes/au/ncc-for-chippies/) gives you the riser, going and rail sizes that decide 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 and footings. ## Adoption status Announced Current code in force NCC 2022 Next edition NCC 2025 (from 1 May 2027) Adoption / transition NCC 2022 still applies to houses, sheds & decks; NCC 2025 is deferred to 1 May 2027.

Where one is installed, QDC MP 4.5 relaxes the fall to 1:100–1:80 (national range is 1:80–1:50), and allows a linear drain, a 10 mm weir or full overflow protection instead of grading the floor at all.
