About the BC Building Code

The BC Building Code, which includes the BC Plumbing Codes, regulates how new construction, building alterations, repairs and demolitions are done in BC. This code sets minimum requirements for safety, health, accessibility, fire and structural protection of buildings and energy and water efficiency. 

The BC Building Code applies to all buildings in B.C. except for

The most recent BC Building Code applies to buildings

  • That are constructed (new buildings)
  • That are altered or renovated
  • Where the use or occupancy changes
  • Where components or parts of a building are replaced

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
  • Has components replaced

Find out more about the BC Codes

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.

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.

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

Our website has links to summaries from recent Codes Canada Public Reviews.

BC-specific code changes are open to public review before they are finalized. Information about current or recent BC reviews are found on our Public Review page.
