How are the codes developed?
Codes in BC are based on the National Codes of Canada (external link) from Codes Canada, but some changes are made to address specific needs for BC.
The model National Codes are developed through a consensus-based committee process with representation from all provinces and territories, related industries and the public. BC participates in the national code development system.
How are the codes enforced?
Local governments have authority to enforce the BC Codes. Check with your local government's building department for info about code enforcement or building permits.

How are the codes organized?
Each code is organized into three sections
- Division A:
- Outlines the main objectives and functional statements for technical building requirements
- Explains why a requirement must be met and how to evaluate other ways to meet the acceptable requirements through alternative solutions
- Division B:
- Outlines Code provisions or acceptable solutions and notes the specific objectives and functional statements used to explain the purpose of each provision
- Division C:
- Outlines administrative requirements under the code such as providing guidance for alternative solutions to the code
