BC Building Codes 2024 take effect March 8, 2024, except for adaptable dwellings and earthquake changes which take effect March 10, 2025.
BC Codes 2024 are largely based on the National Codes 2020 with some BC-specific variations to reflect the province’s geography, climate, local government needs, industry practices, and provincial priorities.
National Code changes incorporated into BC Building Code 2024:
- Enabling mass timber construction
- Requiring rough-ins for radon safety province-wide
- 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

Timing and relevant regulations
The BC Codes 2024 will come into effect on March 8, 2024, and will apply to building permits applied for on or after that date. Buildings with permits in place under the BC Codes 2018 will generally not be affected by the new BC Codes.
The effective date for the new adaptable dwellings and earthquake design changes will be deferred to March 10, 2025, to allow additional engagement and sufficient training to enable low or no-cost design solutions.
This measured approach aims to balance accessibility and housing supply priorities and considers human rights, equity for all people, accessibility engagement feedback, product availability and affordability, and moderate-to-minimal impacts for industry.
