New BC Building Code in Effect March 8, 2024

The Province of B.C. has adopted the 2024 edition of the British Columbia Building Code, including Book II Plumbing Systems (BC Codes 2024).

The new BC Codes 2024 will come into effect on March 8, 2024, and will apply to all building permits submissions on or after that date. Buildings with permits in place, or applications deemed completed prior to March 8, 2024, will remain under the 2018 BC Building Code and will generally not be affected by the adoption of the new BC Codes.

Although the 2024 BC Building Code includes most of the 2020 National Building Code requirements, there are some BC specific code changes.  Further changes will come into effect in 2025.

BC specific changes effective March 2024:

  • More complete and specific language for constructing extended rough-ins for radon subfloor depressurization systems.
  • Adopting cooling requirements to provide one living space that does not exceed 26 degrees Celsius.
  • Retaining existing ventilation requirements for systems serving single dwelling units.

Applications received prior to March 8, 2024, must be deemed complete to be accepted under the 2018 BC Building Code. If we have not received all required documentation for a complete application by March 7, 2024, you will be required to meet the 2024 BC Building Code requirements.
