Can I build a multiplex on my single-family lot in Vancouver now?

Yes, you can likely build a multiplex on your single-family lot in Vancouver — this is now one of the most significant zoning changes in the city's history, allowing 3-6 ownership units or up to 8 secured rental units on most former single-family lots.

Vancouver's new R1-1 Residential Inclusive Zone has replaced the old RS single-family zones across most of the city, including areas like Kitsilano, Shaughnessy, and other previously single-family neighbourhoods. This multiplex policy launched in 2024 and has already generated tremendous interest — multiplexes now represent approximately 50% of all new residential applications in R1-1 zones as of early 2025.

Key requirements for your multiplex project include full compliance with the BC Building Code 2024 (which introduced updated seismic and adaptable dwelling provisions effective March 10, 2025), BC Energy Step Code requirements (currently Step 3, moving to Step 5 by 2032), and all standard City of Vancouver permit processes. You'll need to use a Licensed Residential Builder registered with BC Housing, as any new home construction — including multiplexes — must be covered by the mandatory 2-5-10 home warranty insurance (2 years for materials/labour, 5 years for building envelope, 10 years for structural defects).

The city is launching a streamlined concurrent development and building permit process specifically for smaller multiplexes (up to 4 units), which should help reduce the notorious Vancouver permitting delays. Standard permits currently take 4-8 weeks for simple projects, but complex multiplex developments can take 3-6+ months.

Important considerations include lot size, setback requirements, height restrictions, and parking provisions. Your specific lot's feasibility will depend on dimensions, topography, and any heritage designations. Costs typically range from $200,000-$500,000+ per unit depending on size, finishes, and site complexity — Vancouver construction costs are among Canada's highest, roughly 15-25% above national averages.

Contact the City of Vancouver building department at 311 or vancouver.ca/home-property-development/building-permits to confirm your lot's zoning status and get preliminary guidance.
