What to know about changes to the BC Building Code

The Province is adopting changes to the BC Building Code (BC Code), a provincial regulation that governs how buildings in B.C. get built. Most code changes will come into effect on March 8, 2024, except for adaptable dwellings and earthquake-design changes which will come into effect on March 10, 2025.

A summary of the changes to new residential buildings:

Accessibility:

  • Power-operated doors in all building entrances and universal washrooms.
  • An elevator in all large two- and three-storey apartment buildings.
  • Designated wheelchair spaces in event facilities.
  • More inclusive signage to increase wayfinding and building safety.
  • Full-size change tables in universal washrooms.
  • Assisted-listening systems for people with hearing loss.

Cooling requirements:

  • All new residential buildings must provide one living space that is designed not to exceed 26 C. This may require a cooling appliance in many parts of the province, depending on weather and site conditions.

Mass-timber construction:

  • The Province has permitted the use of mass-timber buildings, in harmonization with the National Building Code 2020, across B.C.

Radon safety:

  • Provincewide adoption of a rough-in for a radon-extraction system.

The Province is deferring the effective date on adaptable dwellings and earthquake-design changes to March 10, 2025, to provide a one-year transition period.

Adaptable dwellings:

Adaptable dwellings are designed and built with features that can be changed to meet occupants’ needs, allowing them to stay in their homes through illness, injury, and/or aging.

  • All residential suites in large residential buildings and ground-floor suites in small apartment buildings will have:
    • accessible clearances through doorways and along paths of travel to living spaces;
    • manoeuvring space in a bedroom, bathroom and kitchen;
    • switches and other controls at an accessible height; and
    • reinforcement of bathroom walls to allow future installation of grab bars.
  • Modest increases for smaller residential housing, such as single-detached homes, townhomes and row homes, will require:
    • reinforcement of bathroom walls to allow future installation of grab bars.

Earthquake design:

  • New methodologies for earthquake design for small buildings, in harmonization with the National Building Code.
  • These changes respond to increased earthquake risks and new national standards to protect new buildings and life safety.
