The intent of the Building Code is to detail the minimum provisions acceptable to maintain the safety of buildings, with specific regard to public health, fire protection, accessibility and structural sufficiency. It is not a textbook for building design. The Building Code concerns construction, renovation, and demolition. It also covers change of use projects where the change would result in increased hazard and/or maintenance and operation in the existing building. The Code sets out technical requirements for the aforementioned project types and does not pertain to existing buildings.
The 1995 National Building Code is split into 9 parts.
- Part 1 Scope and Definitions
- Part 2 General Requirements
- Part 3 Fire Protection, Occupant Safety and Accessibility
- Part 4 Structural Design
- Part 5 Environmental Separation
- Part 6 Heating, Ventilating and Air-conditioning
- Part 7 Plumbing Services
- Part 8 Safety Measures at Construction and Demolition Sites
- Part 9 Housing and Small Buildings
Part 1 gives the definitions and describes how the building code is applied. Houses and certain other small buildings (less than 3 storeys high and 600 m2) are considered "Part 9 Buildings" and only parts 1, 2, 3, 5, 6, 7, 8 and 9 apply. Larger buildings are considered "Part 3 buildings" and parts 1 through 8 apply. Part 3 is the largest and most complicated part of the building code. It is intended to be used by engineers and architects. Part 9 is very prescriptive and is intended to be able to be applied by contractors.
The building code also references hundreds of other construction documents that are legally incorporated by reference and thus part of the enforceable code. This includes many design, material testing, installation and commissioning documents that are produced by a number of private organizations. Most prominent among these are the Canadian Electrical Code, Underwriters Laboratories of Canada a subsidiary of Underwriters Laboratories, documents on fire alarm design, and a number of National Fire Protection Association documents.
