How to Build a Multiplex in Vancouver
A concise 2026 guide to eligibility, permits, costs, financing, and timelines to deliver 3-6 units on a detached lot.
Building a multiplex in Vancouver means converting a single-family lot into 3 to 8 dwelling units under the city's R1-1 zoning district, which replaced all RS zones in 2024 following BC's Bill 44. Most R1-1 lots qualify for 3 to 6 strata units, or up to 8 secured rental units on larger lots. The total project cost for a typical 5,200 sq ft fourplex runs about $5.6 million — roughly $2.8M land, $2.25M construction, and $550K in soft costs and contingency. VanPlex has guided multiplex projects from feasibility through construction across Vancouver, Burnaby, and the Fraser Valley. Plan approximately 20 months from feasibility to occupancy, with 6 to 9 months in permitting. Source: City of Vancouver R1-1 zoning bylaw, June 2024; VanPlex project data, 2026.
Quick overview
- Most R1-1 lots can support 3-6 units (or 8 rental-only units) depending on width, depth, and context. For projects with 5 or more dwelling units, a registered architect is required under the Architects Regulation.
- Two approvals are typical: Development Permit followed by Building Permit
- FSR is 1.0 base, upgradeable to 1.25 with net-zero energy design
- Plan approximately 20 months end-to-end, with 6-9 months in permitting
- Median ROE is 15% (2026), though returns vary by property
Step-by-step

- Run feasibility with an architect and builder
- Submit Development Permit with complete drawings

FAQs
How many units can I build?
Most eligible lots can deliver 3-6 units based on lot size, frontage, and design. Corner and wider lots often allow more flexibility.
What are the key constraints?
Height, setbacks, FSR, site coverage, trees, utilities, and parking shape massing and layouts.
Can I keep a unit for my family?
Yes. Many owners retain one or two homes and sell the remainder to capture value and support multigenerational living.
Is net-zero worth it?
If feasible, net-zero can add buildable area and marketing value. Assess early with your architect and energy consultant.
