Expansion of single egress stairs usage in update to B.C. building code

The government of British Columbia has recently made updates to the BC Building Code (BCBC) in order to allow for single egress stair (SES) designs in low- and mid-rise buildings. This change eliminates the previous requirement for a second egress stairwell per floor in buildings up to six storeys, opening up new possibilities for housing projects on smaller lots and in different configurations.

By allowing for SES designs, the BCBC update aims to provide more flexibility for multi-bedroom apartments, increase density within transit-oriented developments, and potentially improve energy efficiency in buildings. Provincial minister of housing Ravi Kahlon emphasized the importance of innovating and building differently to address the housing shortage and meet the needs of individuals and families.

It is important to note that all new SES designed buildings will need to adhere to specific safety measures, such as sprinklers, smoke-management systems, and wider stairwells. These changes were developed following the release of a report in June 2024, which included input from industry professionals and stakeholders in the fire services community.

Moving forward, the provincial ministry of housing will continue to work with the Office of the Fire Commissioner to address any safety concerns raised during the engagement process. By implementing these updates to the BCBC, British Columbia aims to not only increase housing supply but also provide more options for residents to live, grow, and prosper in the communities they call home.

B.C. Building Code Update: Mass Timber Allowed in Buildings up to 18 Storeys

British Columbia Embraces Expansion of Mass Timber Construction

The use of mass timber in British Columbia is on the rise, with new building-code changes allowing for the construction of buildings up to 18 storeys using this innovative material. This marks an increase from the previous 12-storey limit and opens up exciting possibilities for the use of mass timber in a variety of building projects, including schools, libraries, housing, retail, industrial construction, and care facilities.

Housing Minister Ravi Kahlon heralds these changes as a significant step towards reducing carbon pollution, supporting the forestry sector, creating jobs, and increasing the availability of homes in the province. Mass timber, also known as engineered wood, offers a sustainable alternative to traditional building materials like steel and concrete. Made from smaller wood components connected with adhesives, dowels, nails, or screws, mass timber is not only strong and durable but also environmentally friendly.

Jagrup Brar, Minister of State for Trade and chair of the Mass Timber Advisory Council, views this expansion as a key opportunity to diversify both the forestry and construction industries in British Columbia. By embracing mass timber construction, the province is taking a proactive approach to addressing housing affordability and the climate crisis.

Betsy Agar, director of buildings at the Pembina Institute, a clean energy think tank, commends the province for incorporating mass timber into the B.C. Building Code as a tangible solution to the challenges of housing affordability and climate resilience. She emphasizes the importance of embodied carbon awareness in building design and highlights the benefits of living in safe, healthy, and energy-efficient homes that are affordable to heat and cool.

Overall, the expansion of mass timber construction in British Columbia is a positive step towards a more sustainable and resilient built environment. As the province continues to adopt this innovative building technology, it is not only creating economic opportunities but also contributing to a greener future for all Canadians.
