Build Your Multiplex

In most cases, yes. BC's Bill 44 (2023) now requires municipalities to allow small-scale multi-unit housing on most residential lots. This means lots previously zoned for single-family homes can now accommodate duplexes, triplexes, or fourplexes depending on lot size and location. Your specific eligibility depends on your municipality's updated zoning bylaws, lot dimensions, and servicing capacity.

A typical multiplex build in Greater Vancouver takes 12 to 24 months from initial planning to occupancy. This breaks down roughly as: 1–3 months for design and architecture, 2–6 months for permits (varies significantly by municipality), and 8–14 months for construction. Factors like lot conditions, design complexity, and seasonal weather can affect timelines.

It depends on your municipality and the specific zoning provisions. Some cities require owner-occupancy for certain multiplex types, while others allow full rental of all units. For example, some Vancouver zoning districts require the owner to occupy one unit in a duplex. Your consultation will clarify the rules for your specific lot and city.

Each municipality has slightly different rules under Bill 44. Vancouver allows up to 6 units on larger lots in certain zones. Burnaby permits up to 4 units on standard residential lots. Surrey has adopted policies for up to 4 units on most single-family lots. Setback requirements, height limits, and lot coverage ratios vary by city. We'll review the exact rules for your lot during your consultation.

Construction costs in Greater Vancouver typically range from $350–$500 per square foot, depending on finishes and complexity. A duplex (2,400–3,200 sq ft total) might cost $850K–$1.6M to build, while a fourplex (4,000–5,500 sq ft total) could run $1.4M–$2.75M. These figures exclude land costs. Your consultation includes a personalized cost estimate based on your lot and goals.

In many cases, yes — especially for purpose-built rental multiplexes. BC's housing legislation encourages rental housing, and many municipalities offer incentives like reduced parking requirements or expedited permits for rental-focused projects. Some zoning categories may require owner-occupancy of one unit. We'll clarify the rental rules for your specific situation.

Several financing paths exist for multiplex construction: construction mortgages (draw-based lending during the build), CMHC's MLI Select program for rental housing, conventional mortgages for completed projects, and home equity lines of credit for existing homeowners. Some municipalities also offer development cost charge waivers or density bonuses. A specialist can help you structure the most advantageous financing.

Not necessarily. Some lots can accommodate a new multiplex alongside an existing structure (like a laneway house arrangement), while others may require demolition of the existing home. The decision depends on your lot size, the existing structure's condition, and your municipality's rules. In some cases, renovating and converting an existing home into multiple units is also an option.

Parking requirements have been significantly reduced across BC. Many municipalities now require just 0.5 to 1 parking space per unit for multiplexes, down from the previous 1–2 spaces. Properties near transit may qualify for further reductions or even zero parking requirements. This makes more of your lot available for living space.

Look for builders with specific multiplex or multi-family experience — it's different from single-family construction. Key qualifications include experience with your municipality's permit process, references from completed multiplex projects, familiarity with multi-unit building code requirements, and membership in industry associations like HAVAN or UDI. We can connect you with vetted builders during your consultation.
