The NCC is a performance-based code for building and plumbing, comprising:

  • NCC Volume One – Building Code of Australia for Class 2 to 9 buildings
  • NCC Volume Two – Building Code of Australia for Class 1 and Class 10 buildings
  • NCC Volume Three – Plumbing Code of Australia
Volume one Volume two Volume three

The NCC is freely available online by registering at the ABCB website (  It is also available for purchase in print copy or electronic formats from commercial providers.

The NCC is amended every three years. This amendment schedule aims to reduce red tape and provide industry with higher levels of certainty about the regulation. Less frequent changes mean the industry has a better chance of being abreast of the current requirements in the code.
