Convert Your Vancouver House to a Multiplex
How R1-1 zoning lets you transform a single-family lot into 3-6 units — and why demolish-rebuild usually beats renovation.
R1-1 conversion options in Vancouver
Vancouver's R1-1 zoning (formerly RS zones) now permits multiplex development on nearly every single-family lot in the city. Property owners have three primary paths:
Demolish & Rebuild
Remove the existing house and build a purpose-designed multiplex from scratch. This is the most common and usually most profitable approach.
Best for: Most properties. Maximizes units, FSR, and value.
Renovate & Add Units
Keep the existing structure and add units through internal subdivision, additions, or laneway house. Limited by existing building constraints.
Best for: Heritage homes or when budget is very constrained.
Hybrid Approach
Retain part of the existing structure (often the front portion for streetscape continuity) and build new units behind or above.
Best for: Character areas where streetscape context matters.
Demolish vs. renovate: the numbers
| Factor | Demolish & Rebuild | Renovation/Conversion |
|---|---|---|
| Typical unit count | 4-6 units | 2-3 units |
| Construction cost | $2.0M-$2.5M | $1.6M-$2.2M |
| Total project value | $5.5M-$7.0M | $3.5M-$4.5M |
| Timeline | 18-24 months | 14-20 months |
| ROE | 12-20% | 8-14% |
| Energy efficiency | Step Code 3-5 compliant | Limited by existing envelope |
| Design flexibility | Full control | Constrained by existing structure |
Vancouver-specific considerations
- R1-1 base FSR is 1.0, upgradeable to 1.25 with net-zero energy design — this bonus only applies to new construction
- Tree protection is strict in Vancouver. Significant trees (20cm+ diameter) require arborist assessment and may limit building placement
- Development Cost Levies in Vancouver range from $25-$35 per sq ft — budget $130K-$180K for a typical fourplex
- Parking requirements have been reduced under SSMUH but lane access still determines the parking layout
- Heritage-listed properties face additional constraints — check the Vancouver Heritage Register before planning demolition
Timeline for a Vancouver house-to-multiplex conversion
- Feasibility and design: 2-3 months — zoning check, proforma, architect engagement
- Development Permit: 4-6 months — Vancouver's DP process is thorough
- Building Permit: 2-3 months — can overlap with late DP review
- Demolition: 2-4 weeks — requires separate demolition permit
- Construction: 10-14 months — foundation through finishing
- Occupancy and sales: 1-2 months — final inspections and handover
Total: approximately 20-28 months for demolish-rebuild in Vancouver.
FAQs
Can I convert my existing Vancouver house into a multiplex?
Under R1-1 zoning, most single-family lots now allow 3-6 units. However, most projects involve demolishing and rebuilding to maximize units and meet modern building codes.
Should I demolish or renovate?
Demolish is usually better financially. Renovation costs 80-90% of new construction while delivering fewer units and compromised layouts. New construction maximizes FSR and creates marketable modern units.
How many units can I build on my R1-1 lot?
Most R1-1 lots support 3-6 strata units or up to 8 rental-only units, depending on lot width, depth, and lane access.
