Multiplex Zoning in British Columbia
A plain-language guide to zoning rules, zone designations, and how to determine whether your property qualifies for multiplex development.
How to check your property's zoning
Every property in BC has a zoning designation that determines what can be built on it. Before BC's SSMUH legislation, most residential lots were restricted to a single dwelling. Now, the majority of these lots allow 3-6 units — but the specifics depend on your municipality's implementation.
- Find your zoning designation — Use your city's online zoning map or enter your address in VanPlex for an instant lookup.
- Check the zone's permitted uses — Look for "multiple dwelling" or "multiplex" in the zone schedule. Note the maximum number of units.
- Review development standards — FSR, height, setbacks, site coverage, and parking requirements all shape what you can build.
- Identify overlays or special districts — Heritage areas, environmental zones, or design guidelines may add requirements.

Common zoning terms explained
FSR (Floor Space Ratio)
Total buildable floor area divided by lot area. A 5,000 sq ft lot with 1.0 FSR = 5,000 sq ft of building.
Setbacks
Minimum distances from property lines where building is not permitted. Front, rear, and side setbacks vary by zone.
Site Coverage
Maximum percentage of the lot that can be covered by buildings. Typically 40-60% for multiplex zones.
Height Limit
Maximum building height, usually 10-12 metres for residential multiplexes (roughly 3 storeys)
Lot Coverage vs. Buildable Envelope
The three-dimensional space defined by setbacks, height, and site coverage that determines the maximum building volume.
Density Bonus
Extra FSR granted for meeting certain criteria — rental tenure, accessible units, or net-zero energy performance.
FAQs
How do I check if my lot is zoned for a multiplex?
Each municipality has an online zoning map. In Vancouver, use the VanMap tool. In Burnaby, check the Burnaby Zoning Bylaw map. VanPlex can also check your property instantly — just enter your address above.
What is SSMUH and how does it affect zoning?
SSMUH (Small-Scale Multi-Unit Housing) is BC Bill 44, which requires municipalities with over 5,000 residents to allow multiplexes on single-family lots. It overrides local single-family zoning restrictions province-wide.
What does FSR mean for multiplex development?
FSR (Floor Space Ratio) is the ratio of total buildable floor area to lot size. A 5,000 sq ft lot with 1.0 FSR allows 5,000 sq ft of building. Higher FSR means more units and revenue potential.
Can I build a multiplex on an RS-zoned lot in Vancouver?
Yes. Vancouver renamed most RS zones to R1-1, which now permits multiplexes of 3-6 units. The specific number depends on lot width, depth, and whether the project includes rental-only units.
