NCC Icons - Volume One, Volume Two, Volume Three

National Construction Code

The National Construction Code (NCC) provides the minimum necessary requirements for safety and health; amenity and accessibility, and sustainability in the design, construction, performance and livability of new buildings (and new building work in existing buildings) throughout Australia. It is a uniform set of technical provisions for building work and plumbing and drainage installations throughout Australia that allows for variations in climate and geological or geographic conditions.

The NCC is an initiative of the Council of Australian Governments (COAG) developed to incorporate all on-site construction requirements into a single code. The NCC is comprised of the Building Code of Australia (BCA), Volumes One and Two; and the Plumbing Code of Australia (PCA), Volume Three.

  • NCC Volume One primarily applies to Class 2 to 9 (multi-residential, commercial, industrial and public) buildings and structures.
  • NCC Volume Two primarily applies to Class 1 (residential) and 10 (non-habitable) buildings and structures.
  • NCC Volume Three applies to plumbing and drainage for all classes of buildings.

The NCC can be viewed online or downloaded from the NCC Suite.

The Guide to NCC Volume One

The Guide to Volume One is a non-mandatory publication, which has been developed to assist in interpreting the requirements of Volume One. In addition, each NCC Volume contains clearly identified, non-mandatory explanatory information within the text to assist with interpretation of the requirements.

The primary users of the NCC include architects, builders, plumbers, building surveyors, hydraulic consultants, designers and engineers. It is given legal effect through state and territory building control and plumbing legislation.

The Guide to Volume One can be viewed online through related resources in Volume One, or downloaded from the NCC Suite.

Regulatory Reform and National Economic Benefits

The construction sector is a significant industry for Australia and represents the second largest sector of small business in the economy. As a result, constraining cost growth and improving productivity has the potential to deliver significant economic benefits nationally. The building and construction industry has undergone significant regulatory reform over the last twenty years.

A number of these reforms have related to the work of the ABCB, including the:

  • creation of a single, nationally consistent BCA, which occurred in 1992;
  • move to a performance-based BCA, which occurred in 1996;
  • consolidation of building and plumbing regulation, resulting in the NCC in 2011;
  • provision of a free online NCC, which first commenced in 2015; and
  • reduction in the frequency of NCC changes, from a 1-year to a 3-year amendment cycle, commencing with NCC 2016.

In an effort to ascertain the benefits of a national performance-based construction code the ABCB commissioned the Centre for International Economics (CIE) to quantify the impact of building regulatory reform to date and identify any past, present, or potential barriers that may be preventing the full benefits of reform being realised. The report estimates annual national economic benefit of $1.1billion from the suite of building regulatory reforms introduced through the ABCB over the past twenty years.


Building and plumbing regulation has always been inherently linked, as both set the requirements for the on-site construction of buildings. However, historically building and plumbing have been regulated through separate legislative and administrative arrangements. Since 1994 the BCA has been referenced as the primary construction code in all state and territory building legislation; at that time plumbing regulators had not yet agreed (through an IGA) to the adoption of a national code.

In achieving national consistency, COAG asked the Business Regulation and Competition Working Group (BRCWG) to investigate the merits of a national code and to report to COAG by July 2008. On 3 July 2008, COAG agreed to the development of an NCC to cover building, plumbing, electrical and telecommunications standards. The first stage was to consolidate the codes for building and plumbing. This was completed with the release of NCC 2011, which was adopted by states and territories on 1 May 2011.

The Regulation Impact Statement on the proposal for the development of an NCC identified the following potential benefits:

  • Improved consistency between building and plumbing regulations;
  • Improved framework for regulation of plumbing on a national basis;
  • Improved regulatory framework to respond to future policy challenges;
  • Improved regulatory conditions for innovation at the national level; and
  • Opportunity for administrative reform.
