Does the BC Building Code apply to existing buildings?
If there has not been any changes to an existing building, it should meet the requirements of the BC Building Code that was in place when the building was constructed.
For example, if a building was constructed when the BC Building Code 2012 was in effect, it doesn't need to be upgraded to meet the requirements of the BC Building Code 2018.
The current BC Building Code does apply if an existing building
- Is altered or renovated
- Has a change to its use or occupancy

Does the BC Building Code apply to temporary buildings?
Temporary buildings might not need to meet the BC Building Requirements. Contact your local government for temporary building requirements (external link).

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
