The purpose of this Guide is to help Code users understand and apply the provisions in Part 9 of the National Building Code of Canada 2015 (NBC). It is a companion document to NBC Part 9—not a stand-alone document.
The Canadian Commission on Building and Fire Codes (CCBFC) develops Canada’s five National Model Codes. The National Building, Energy, Farm Building, Fire, and Plumbing Codes are adopted, with or without modifications, and enforced by many provinces and territories. When adopted by a provincial, territorial or municipal authority, the National Model Codes become legal documents and their enforcement is then administered in conformance with the appropriate regulations of that authority
In the National Model Codes, most provisions in Division B (acceptable solutions) are linked to at least one objective and functional statement found in Division A. These linkages play an important role in allowing these objective-based codes to accommodate innovation. It is expected that the majority of Code users will primarily follow the acceptable solutions given in Division B and that they will consult Division A only in cases where it may serve to clarify the application of Division B’s provisions to a particular situation or when they are considering an alternative solution.
