Code Requirements


The BC Building Code 2018 combines the requirements of the National Building Code 2015 with B.C.’s existing requirements to achieve a higher level of building accessibility. New requirements help improve accessibility in small retail shops, and common areas of condominium and apartment buildings, as well as allow greater flexibility in design choices. More information on this update can be found in technical bulletin B18-05.

Find illustrations and explanations related to accessibility requirements in the  Building Access Handbook (PDF, 3.6MB). A new edition of the Building Access Handbook will be created to assist code users to learn about the new accessibility requirements in the BC Building Code 2018.

Alternative Solutions

'Alternative solution' replaces the term 'equivalency' used in the 1998 BC Building Code. Code users may propose alternative solutions, or alternative ways of meeting BC Building Code requirements. Alternative solutions require local authority approval.

BC Energy Step Code

The BC Energy Step Code is an optional compliance path in the BC Building Code. It came into force in April 2017. It provides an incremental and consistent approach to achieving more energy-efficient buildings that go beyond the requirements of the base BC Building Code. Find more information on the BC Energy Step Code web page.

Bedroom Windows

The BC Building Code requires at least one window suitable for egress in each bedroom within a house or small multi-family residential building. The window opening must be 0.35M2 with no dimension less than 380mm. If the suite is sprinklered, an egress window is not required. 

City of Vancouver Building Bylaw

The BC Building Code does not apply in the City of Vancouver. Vancouver has its own building bylaw.

Existing Buildings

Buildings are required to conform to the version of the BC Building Code in force when they are constructed. Existing buildings are not automatically required to be upgraded when codes change.

The current building code does apply if an existing building:

  • is altered or renovated
  • has a change to its use or occupancy
  • has components replaced
