What Does a Multiplex Actually Cost to Build in Metro Vancouver?
SSMUH and Bill 44 have made it legal to build a 3-to-6-unit multiplex on most single-family lots across Burnaby, Vancouver, Coquitlam, Port Coquitlam, Port Moody, North Vancouver, West Vancouver, Pitt Meadows, Maple Ridge, and Richmond. But “legal” and “affordable” are two different questions. Before you commit to a design direction, you need a realistic construction budget — one that accounts for demising walls, fire and sound separations, parking, servicing, and the soft costs that don’t show up on a floor plan.
We build detailed cost estimates and tender packages for multiplex projects across the Lower Mainland, broken down by system — structure, envelope, mechanical/electrical/plumbing, fire and sound separation, parking, and amenity space — so you know where your money is going before you break ground, not after.
Every municipality prices differently: development cost charges, servicing requirements, and parking mandates vary city by city. We factor your specific municipality’s requirements into your budget from day one, so your numbers hold up through permit review and tender. Site conditions matter too: in Richmond, raised flood construction levels and soft soils affect foundations and grading, which our Richmond home design and permit drawing service plans for from the start.

Where Multiplex Construction Budgets Actually Go
- Hard Costs: Foundation, framing, envelope, roofing, and finishes — the physical materials and labour of the building itself.
- Fire & Sound Separation: Party walls between units cost meaningfully more than a standard interior wall — often $30-$80+ per square foot depending on the fire and sound rating required, versus $15-$25 for a standard wall.
- Soft Costs: Building permits, development cost charges (DCCs), architectural and engineering fees, and municipal servicing hook-ups.
- Parking & Site Work: Laneway access parking, grading, drainage, and shared outdoor amenity space required by most municipalities.
- Contingency: We recommend budgeting 15% of your total project cost for the unexpected — site conditions, material delays, or inspection revisions.
Why Budgeting Before Design Saves You Money
The most expensive mistake in multiplex development is designing first and pricing second. We prepare a preliminary cost estimate early — before you invest in full construction drawings — so your design direction matches your actual budget from the start. That preliminary “stop/go” checkpoint prevents thousands of dollars in wasted design fees on a plan you can’t afford to build.
Once your design is locked, we prepare detailed tender packages — construction drawings, specifications, and a line-item bill of quantities — so contractor bids are comparing apples to apples, not guesswork.
