Vancouver building code question

What are the Vancouver building code requirements for residential construction?

Vancouver enforces the BC Building Code with additional city by-laws that often exceed the provincial requirements. Residential construction in Vancouver must comply with the BCBC, the Vancouver Building By-law, and city-specific requirements for energy performance, seismic design, rain screening, and accessibility that reflect the city's climate and density context.

Vancouver is unique in Canada because it maintains its own building by-law that historically adopts and sometimes amends the BC Building Code with additional requirements. Residential projects in Vancouver must navigate both the BCBC and the Vancouver Building By-law, along with zoning by-laws and specific requirements for the city's climate conditions.

What to check first

  • Vancouver maintains its own building by-law that can exceed the BC Building Code requirements in specific areas.
  • Energy performance requirements in Vancouver are typically ahead of the base BCBC through the BC Energy Step Code adoption levels.
  • Rain screening, seismic design, and building envelope requirements reflect Vancouver's specific climate and hazard conditions.

Jurisdiction notes

BC Building Code

The BCBC is the provincial building code. Vancouver adopts it through the Vancouver Building By-law with specific amendments and additions.

Vancouver Building By-law

Vancouver's building by-law can include requirements that exceed the BCBC. Check the current by-law for Vancouver-specific provisions before assuming the BCBC alone applies.

Energy Step Code

Vancouver typically adopts higher BC Energy Step Code levels than the provincial minimum. Confirm the current required step for your project type.

Work through it in this order

  1. Check the current Vancouver Building By-law for any requirements that exceed the BCBC for your project type.
  2. Confirm the applicable BC Energy Step Code level for the project.
  3. Verify seismic design, rain screening, and building envelope requirements specific to the Vancouver context.
  4. Coordinate building code compliance with Vancouver zoning and development permit requirements.

Common questions

Does Vancouver follow the BC Building Code exactly?

Not always. Vancouver maintains its own building by-law that adopts the BCBC with amendments. Some Vancouver requirements exceed the provincial code.

What Energy Step Code level is required in Vancouver?

Vancouver typically requires higher step levels than the provincial minimum. The required level depends on the project type and the current by-law. Check the city's current requirements.

Are rain screen walls required in Vancouver?

Rain screening requirements are part of the building envelope strategy in Vancouver. The specific requirements depend on the building type, height, and by-law provisions. This is a critical design consideration for the local climate.
