National Construction Code (NCC)
The main technical rules that set minimum standards for how buildings must be designed and constructed in Australia.
The Building Code of Australia (BCA) forms part of the National Construction Code (NCC) and sets out the technical standards for building work "things like structure
What does it mean for my project?
While planning controls (like LEPs and DCPs) say *what* you can build and where the BCA/NCC says *how* it must be built to be safe healthy and durable.
What do I need to think about?
Builders, certifiers and designers must ensure that building work complies with the relevant NCC volume and referenced Australian Standards. The NCC is updated regularly (typically every 3 years) so requirements for insulation glazing accessible features and energy efficiency can change over time.Your plans must be capable of complying with the NCC or they won't pass certification Additional reports (fire safety structural energy accessibility) may be required to demonstrate compliance Design decisions (like window size stair layout ceiling heights) are influenced by NCC minimums Changes to NCC can increase costs (for example higher energy efficiency standards) " factor this into budget and timelinesDon't assume "that's how we've always done it" is still compliant " check the current NCC version Some performance-based solutions require detailed justification and specialist consultants Bushfire, flood and other hazard controls may overlay additional construction requirements beyond NCC minimums A private certifier can refuse to issue a Construction Certificate if they believe the design won't comply
Examples where it might impact a project
The NCC requires our new bathroom to have a certain ceiling height and ventilation, can't get a Construction Certificate without meeting it.
State specific stuff...
No state specific requirements - used across Australia (check your local council for any local variations).
