The 2024 BC Building Code came into effect on March 8, 2024. However, seismic and adaptable dwelling unit provisions from the 2018 BC Building Code remained in effect for projects with building permits applied for before March 10, 2025. Starting March 10, 2025, all projects with building permits must fully comply with the 2024 BC Building Code, including the updated seismic design requirements.
What is Seismic Design?
Seismic design is the process of engineering buildings to withstand earthquakes and high winds. The goal is to enhance safety and minimize damage to buildings and infrastructure during seismic events.
Seismic Design Requirements
All new buildings constructed in British Columbia, including those in areas that previously did not require seismic considerations—such as Creston—must now comply with BC Building Code 2024 Section 9.23. The redesign of Section 9.23 introduces significant changes to accommodate increased seismic activity, particularly Subsection 9.23.13, which addresses bracing to resist lateral loads caused by wind and earthquakes.
BC has some of the highest seismic hazard values in Canada, making these updates essential. The revised methods for lateral load resistance provide new solutions that allow designers to continue working within the parameters of Part 9 of the BC Building Code.

To help builders and designers navigate these important updates, the Town of Creston is offering a specialized course covering the changes to Part 9 bracing requirements for wood frame construction. These new requirements, taking effect March 10, 2025, will apply to all Part 9 housing in BC, including areas with historically low seismic and wind risk.
This course is highly recommended for builders, contractors, designers, and anyone involved in residential construction in BC.
