Missing Middle Housing in British Columbia

From Vancouver to Kelowna, BC is restoring the housing types that were banned for decades. Multiplexes, rowhouses, and cottage courts are creating attainable homes in established neighbourhoods—filling the gap between detached houses and towers.

What missing middle means in BC

British Columbia's housing market has been shaped by a peculiar zoning legacy. After World War II, most municipalities restricted residential land to single-family homes, while concentrating multi-family housing in narrow tower zones along transit corridors. The result was a binary housing landscape: houses or apartments, with almost nothing in between.

The "missing middle" refers to the building types that this zoning erased—duplexes, triplexes, fourplexes, rowhouses, and cottage courts. These forms were common in BC's pre-war neighbourhoods and remain common in cities worldwide. They provide more density than detached homes at a fraction of the cost and complexity of tower development.

With provincial legislation (Bill 44) now requiring municipalities to permit multi-unit housing, missing middle is rapidly returning to BC. Each city implements the mandate differently, but the objective is the same: diverse, attainable housing in every neighbourhood.

The density spectrum

+1 unit

Laneway / ADU

Secondary dwelling added to existing lot. Lightest intervention.

2 units

Duplex

Two dwellings in one structure. Side-by-side or stacked.

3 units

Triplex

Three units. Often stacked over three floors.

4 units

Fourplex

Four independent homes. Most common SSMUH form.

6 units

Sixplex

Maximum density in most SSMUH bylaws. Best lot economics.

4-6 units

Cottage court

Detached small homes around shared green space.

Which BC cities are enabling missing middle

Every municipality in BC is required to update its zoning to permit multi-unit housing under Bill 44. Here is where the major cities stand in their implementation.

Vancouver

Active

R1-1

3-6 strata units or 8 rental. Net-zero FSR bonus. No public hearing for conforming.

Burnaby

Active

R1 SSMUH

3-6 units. No FSR cap—envelope controls. Fee-simple titles available. FTNA parking exemptions.

Surrey

Active

SSMUH zones

3-6 units on residential lots. Focus on servicing and infrastructure coordination.

Coquitlam

Active

Bill 44 compliance

Multi-unit housing permitted. Transit-oriented areas near Evergreen Line stations prioritized.

New Westminster

Active

Updated R zones

Missing middle forms enabled across residential areas. Historic neighbourhood design guidelines.

Kelowna

In progress

OCP update

Interior BC leader in missing middle. Infill housing strategy targeting established neighbourhoods.

Comparing density options

Not every missing middle form suits every lot or every owner. Here is how the main options compare on key dimensions.

Type Units Build cost/unit Timeline Best for
Laneway / ADU +1 $250K-$400K 8-14 months Rental income, aging-in-place
Duplex 2 $350K-$500K 14-18 months Owner-occupant with rental
Triplex 3 $300K-$450K 16-20 months Multi-generational families
Fourplex 4 $280K-$400K 18-22 months Best balance of density and simplicity
Sixplex 6 $260K-$380K 20-26 months Maximum density and ROI
Cottage court 4-6 $300K-$450K 20-28 months Premium product, detached units

Costs are approximate and vary significantly by city, lot conditions, and design choices

The policy landscape: Bill 44 and beyond

BC's provincial government has created the most progressive missing middle housing framework in Canada. Here are the key policy pillars supporting the movement.

Bill 44: Housing Statutes Amendment Act

Requires all BC municipalities to permit multi-unit housing on residential lots. Sets minimum density thresholds based on community size: 3-4 units in smaller communities, up to 6 units in larger cities. Municipalities must update bylaws within prescribed timelines or provincial standards apply automatically.

Bill 46: Transit-Oriented Development

Enables higher density near transit stations, complementing missing middle housing in surrounding neighbourhoods. Creates a density gradient from transit hubs outward: highest density at stations, medium density along corridors, and gentle density in residential areas.

Municipal SSMUH bylaws

Each city implements provincial requirements through its own Small-Scale Multi-Unit Housing bylaw. These bylaws set specific height limits, setbacks, parking ratios, and design guidelines. The variation between cities creates different opportunities—understanding your municipality's specific SSMUH rules is essential.

BC Building Code updates

The BC Building Code has been updated to accommodate missing middle building types, including provisions for wood-frame construction up to six storeys, energy efficiency requirements aligned with the BC Energy Step Code, and accessibility standards that ensure inclusive design.

Frequently asked questions

What does 'missing middle housing' mean in a BC context?
In BC, missing middle housing refers to multi-unit residential buildings between single-family homes and mid-rise apartments: duplexes, triplexes, fourplexes, sixplexes, rowhouses, and cottage courts. These housing types were common before post-war zoning restricted most residential land to single-family use. Bill 44 and municipal SSMUH bylaws are now restoring them across the province.
Which BC cities are enabling missing middle housing?
Vancouver (R1-1 zoning), Burnaby (R1 SSMUH), Surrey, Coquitlam, New Westminster, and Port Coquitlam are the most active. Kelowna, Victoria, and Nanaimo are also advancing missing middle policies. Smaller communities like Squamish, Whistler, and Kamloops are in various stages of bylaw updates to comply with Bill 44 requirements.
What is the difference between a laneway house, duplex, fourplex, and sixplex?
A laneway house adds one small unit (500-750 sq ft) to the rear of an existing lot. A duplex divides one building into two units. A fourplex contains four independent units and typically replaces the existing home. A sixplex contains six units and represents the maximum strata density under most SSMUH bylaws. Each step up delivers more housing per lot.
How does missing middle housing compare to towers on affordability?
Missing middle units typically cost 25-40% less per square foot than new tower condos because construction is simpler (wood-frame vs. concrete, no underground parking, no elevators). Units also avoid the $400-$800/month strata fees common in towers. Total cost of ownership for a missing middle unit is often 20-30% lower than a comparable tower condo.
What is the BC policy landscape for missing middle housing?
Bill 44 (Housing Statutes Amendment Act) requires municipalities to allow multi-unit housing on residential lots. Bill 46 enables transit-oriented development with higher density near transit. Together, these provincial laws create the legal framework for missing middle housing, while individual municipalities set specific zoning parameters (height, setbacks, unit counts) through their SSMUH bylaws.
