The National Building Code of Canada 2015, together with the National Plumbing Code of Canada 2015, the National Fire Code of Canada 2015 and the National Energy Code of Canada for Buildings 2017, is an objective-based National Model Code that can be adopted by provincial and territorial governments. Codes Canada^[1] are developed by the Canadian Commission on Building and Fire Codes (CCBFC).

In Canada, provincial and territorial governments have the authority to enact legislation that regulates building design and construction within their jurisdictions. This legislation may include the adoption of the National Building Code (NBC) without change or with modifications to suit local needs, and the enactment of other laws and regulations regarding building design and construction, including the requirements for professional involvement.

The NBC is a model code in the sense that it helps promote consistency among provincial and territorial building codes. Persons involved in the design or construction of a building should consult the provincial or territorial government concerned to find out which building code is applicable.

This edition of the NBC succeeds the 2010 edition.
