Building Code Requirements in Queensland
Which edition of the National Construction Code applies in Queensland, its adoption timeline, and the state-specific variations that affect what you build.
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 gives you the riser, going and rail sizes that decide pass or fail, and the concrete calculations guide helps you order the right amount for slabs and footings.

State variations
- HP 10.2
Queensland does not require a floor waste in a Class 1 bathroom or laundry — only in shower areas (10.2.14). 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.
