In the Northern Territory, houses, sheds and decks (Class 1 and Class 10) are built to **NCC 2022**. The NT has *not* brought in NCC 2025. NCC 2022 keeps applying here, so unlike the eastern states there’s no 2027 switch-over date on the books. For every job you’re pricing or setting out, NCC 2022 is the rule book. That means the basics are the thing to nail. Our [NCC-for-chippies stairs pillar](https://www.chippy.tools/building-codes/au/ncc-for-chippies/) sets out the riser, going and rail limits, 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 Frozen Current code in force NCC 2022 Next edition Not adopted Adoption / transition NCC 2022 continues in the NT; NCC 2025 is not adopted (stays until the next NCC edition is published).
