National Building Code of Canada 2005

The 2005 edition of the National Building Code of Canada (NBC) is now available. Over 800 technical changes have been incorporated in this new edition. The NBC sets out technical provisions for the design and construction of new buildings. It also applies to the alteration, change of use and demolition of existing buildings.

New information has been added to make the NBC 2005 clearer, easier to apply to existing buildings and more accommodating to innovation. It explains the objectives that the Code's provisions are intended to achieve and describes the functions that a building or its components must perform to fulfill these objectives.

The NBC is available in two volumes and has a new organizational layout that comprises three divisions: Divisions A, B and C. Division A includes the compliance options, the objectives and the functional statements. Division B contains the provisions - now referred to as "acceptable solutions" - relating to such issues as fire protection, occupant safety and accessibility, structural design, environmental separation, heating, ventilating and air-conditioning, plumbing services and housing and small buildings. Division C contains administrative provisions. Volume 1 contains Divisions A, B and C, and Volume 2, the appendices to these divisions as well as the index.

The NBC 2005 complements the National Fire Code of Canada 2005, and both are indispensable for officials, educators and construction professionals.
