BC Building Code Requirements
Effective March 8, 2024, the new BC Building Code applies to all building permit applications.
BC Building Code changes to be incorporated in 2024 include:
- Requiring rough-ins for radon safety province-wide.
- 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.
*Buildings with permits in place under the BC Building Code 2018 will generally not be affected by the new BC Building Code.
Additional BC Building Code changes for new adaptable dwellings and earthquake design changes will come into effect March 10, 2025. These changes will include:
- Reinforcement of bathroom walls to allow future installation of grab bars.
- Early adopting national provisions to improve earthquake design changes for housing and small buildings with high seismic hazard values.
BC Energy Step Code
Compliance with Step 3 of the BC Energy Step Code is required throughout British Columbia, including the Squamish-Lillooet Regional District. All newly constructed and substantially reconstructed homes will require pre-building permit energy modelling performed by a certified Energy Advisor. Energy Advisors will be required to return mid-construction and prior to occupancy to confirm that the work meets the pre-construction modelling. Occupancy permits will be contingent upon the SLRD receiving a compliant final energy advisor report.
