Thirteen communities have signed on to be early adopters of tall wood buildings using mass timber technology. “Increasing and finding new uses of British Columbia forestry products means we are creating beautiful energy-efficient homes while supporting jobs and local economies,” said George Heyman, minister of environment and climate change strategy. “Changes to the building code to promote efficiency is part of our CleanBC plan to reduce emissions in new construction while improving energy efficiency in existing buildings.”
The move to large wood buildings has been controversial in many parts of the country. Ontario only recently amended it’s building code to allow six-storey wood structures, up from four. The degree of expansion and contraction in wood buildings can cause challenges with piping and ductwork and fire officials have expressed concern about the potential fire risk.
The new B.C. Building Code is also designed to increase the supply of homes by allowing secondary suites in multi-family buildings (duplexes and townhouses). The regulations remove maximum size restrictions but will require fire separations between residences.
Energy Step Code requirements have also been introduced for public sector buildings, such as hospitals, schools, community centres and university classrooms.

Changes to the B.C. Building Code are also designed to enhance the safety of residents. These changes include requirements for carbon monoxide detectors in commercial buildings and assembly buildings – such as schools, offices and places of worship, increased lighting in recycling rooms, and additional requirements for fire alarms and exits on roof-top enclosures – such as patios.
The building code changes apply to building permit applications on or after Dec. 12. The B.C. Building Code establishes minimum requirements for health, safety, accessibility, fire and structural protection, and energy and water efficiency.
The code applies to building construction and renovation throughout B.C., except for some federal lands and the City of Vancouver – which has its own building bylaw. An online version of the new B.C. Building Code is available free of charge and printed copies are available at a reduced rate.
