The VBA's Building Practice Notes explain different parts of the building legislation, making it easier to find and understand the information relevant to you.

What is the National Construction Code?

The National Construction Code (NCC) sets out the requirements for the design and construction of buildings in Australia, including plumbing and drainage work. It sets the minimum required level for the safety, health, amenity, accessibility, and sustainability that most types of new building designs must comply with.

The Australian Building Codes Board (ABCB) and Building Ministers’ Meeting (BMM) act on behalf of the Commonwealth, State and Territory Governments to produce and maintain the NCC which is updated triennially.
Collectively, Volume One and Two of the NCC are titled the Building Codes of Australia (BCA). Volume Three makes up the Plumbing Code of Australia (PCA).

Volume One: Class 2 to 9 buildings

Volume Two: Class 1 and 10 buildings

Volume Three: Plumbing and drainage work associated with all classes of buildings

Building standards in Victoria

NCC requirements are given legal effect in Victoria through the Building Act 1993, Victorian Building Regulations 2018, and Victorian Plumbing Regulations 2018. These regulations set out the framework for the regulation of building construction, building standards (including NCC) and the maintenance of specific building safety features in Victoria.

The Victorian Building Authority (VBA) regulates practitioner building and plumbing compliance standards as set out in the NCC. For more information visit: Victorian Building Authority

Your appointed building surveyor is responsible for issuing the building permit and ensuring your proposed building design is compliant with the
Victorian and national building standards. Find more information on how building surveyors support the building and design process.
