How many units can I build on my lot in Surrey?

Most former single-family lots in Surrey now allow up to 4 dwelling units on a standard lot (between 280 m² and 4,050 m²), and up to 6 units on eligible lots inside a Frequent Bus Stop Area. Small lots under 280 m² are capped at 3 units, and very large estate lots over 4,050 m² are limited to 2. Run your address to get the figure for your specific parcel.

Which Surrey zones allow small-scale multi-unit housing?

Surrey rewrote its residential zones to implement Bill 44 (SSMUH): RA (Acreage Residential), R1 (Suburban Residential), R2 (Quarter Acre Residential), R2-O (Oceanfront Residential), R3 (Urban Residential), R4 (Small Lot Residential), R5 (Compact Residential), R5-S (Special Compact Residential) and R6 (Semi-Detached Residential) all now permit multiple units by lot size. Every one of them allows up to 6 units on an eligible lot inside a Frequent Bus Stop Area.

Do I need to rezone to build a multiplex in Surrey?

No. Small-scale multi-unit housing is a permitted use in Surrey's residential zones, so an eligible project proceeds to development and building permits rather than a discretionary rezoning. You still have to meet the zone's floor-area ratio, coverage, height, and setback rules.

When can I get 6 units on a Surrey lot?

In any of the nine small-scale residential zones (RA, R1, R2, R2-O, R3, R4, R5, R5-S and R6), a lot of 280 m² up to 4,050 m² can have up to 6 dwelling units if it is an eligible lot inside a Frequent Bus Stop Area. Which areas qualify is mapped in Schedule F of the Zoning Bylaw. The 6 counts every dwelling unit on the lot, so it comes from a house or duplex plus secondary suites, a garden suite or a coach house. Outside those areas the cap is 4.

Why would my Surrey lot only allow 2 units?

Three situations drop a lot back to 2 units: a lot larger than 4,050 m² (estate-scale), a lot that is not connected to community water and sewer, or a heritage-protected property. Lots inside a Provincial Transit-Oriented Area are also outside the SSMUH framework - they're governed by higher-density transit rules instead.

How is buildable area measured in Surrey?

Unlike Burnaby, Surrey regulates density with floor-area ratio (FAR). A duplex is generally FAR 1.0 on the first 560 m² of lot plus 0.60 on the remainder (basements included), with height up to 11 m / 3 storeys and lot coverage up to 50–60%. A single detached house alternative uses a lower FAR. Garage-area requirements are waived inside Frequent Bus Stop Areas.

Until 2024, most residential lots in Surrey were limited to a single house - often with a suite or coach house. That changed when the province passed Bill 44, the Small-Scale Multi-Unit Housing (SSMUH) legislation, and Surrey responded by rewriting its residential zones so that small multiplexes are permitted outright on ordinary lots.

The short version: a standard Surrey lot (between 280 m² and 4,050 m²) now permits up to 4 dwelling units - and up to 6 units on eligible lots inside a Frequent Bus Stop Area. Secondary suites count toward the total.

Small lot Up to 3 units Under 280 m² Standard lot Up to 4 units 280 m² – 4,050 m² Near frequent transit Up to 6 units Eligible lot in a Frequent Bus Stop Area, any of the nine zones The honest caveat

These are the framework numbers from Surrey's residential zone schedules. Your actual entitlement depends on lot area, transit proximity, servicing, and heritage status - and a few situations (estate lots over 4,050 m², lots off community water/sewer, heritage properties, or Transit-Oriented Areas) change the answer. Always confirm against the current bylaw - or just run your address and let ZoneScout pull the figure for your parcel.

What Bill 44 actually requires

Bill 44 - the Housing Statutes (Residential Development) Amendment Act, passed in late 2023 - requires most BC municipalities over 5,000 people to allow Small-Scale Multi-Unit Housing on land previously reserved for single-family homes or duplexes. The provincial minimums are:

At least 3 units on most lots previously zoned single-family or duplex.
At least 4 units on lots larger than roughly 280 m².
Up to 6 units on larger lots within 400 m of frequent (bus or rail) transit service.

Surrey implemented these requirements by restructuring its residential zones - and the 280 m² lot-area threshold in the bylaw maps directly onto the provincial line.

How Surrey implemented it: nine residential zones

Rather than create one new zone, Surrey folded SSMUH into its existing residential districts. If your property is in one of these, it now carries the small-scale multi-unit rules:

R1 - Suburban Residential and R2 - Quarter Acre Residential: larger-lot districts; up to 4 units on standard lots, 2 on estate lots over 4,050 m².
R3 - Urban Residential: Surrey's most common urban lot; up to 4 units on standard lots. R3 is also the only one of these zones that permits a houseplex - a building of 3 or 4 principal units with no secondary suites - and only on a corner lot, a through lot, or a lot with lane access.
R4 - Small Lot Residential: compact lots; up to 4 units on standard lots, 3 on lots under 280 m².
R2-O - Oceanfront Residential: the same tiers with larger setbacks protecting the waterfront character.
RA - Acreage Residential, R5 - Compact Residential, R5-S - Special Compact Residential and R6 - Semi-Detached Residential: the same unit tiers on acreage, compact and semi-detached lots.

In every one of these nine zones, an eligible lot of 280 m² up to 4,050 m² inside a Frequent Bus Stop Area can go from 4 units to 6.

All of this is outright - permitted by the zone - so an eligible project goes straight to development and building permits instead of a rezoning.

What actually drives your unit count

Lot area

Surrey uses three lot-size bands: under 280 m² caps you at 3 units, 280–4,050 m² allows up to 4, and over 4,050 m² drops back to 2 (these estate-scale lots are treated as large single-family parcels). A typical Surrey residential lot sits comfortably in the middle band.

Transit proximity

The jump from 4 to 6 units is about location, not zone or lot shape: every one of the nine zones allows 6 on an eligible lot inside a Frequent Bus Stop Area, the areas around frequent bus stops mapped in Schedule F of the bylaw. The 6 counts every dwelling unit, so it is built as a house or duplex plus suites, a garden suite or a coach house; a houseplex alone tops out at 4. Inside these areas Surrey also waives the required garage area.

Servicing and heritage

Two things quietly cap a lot at 2 units regardless of size: not being connected to community water and sewer, and being a heritage-protected property. It's worth checking both before you count on a multiplex.

Floor-area ratio, not just coverage

Unlike Burnaby's R1 zone, which controls size purely through lot coverage, Surrey uses floor-area ratio. A duplex is generally FAR 1.0 on the first 560 m² plus 0.60 on the remainder (basements included), within an 11 m / 3-storey envelope and 50–60% coverage. A single-detached house alternative uses a lower FAR.

Transit-Oriented Areas are different

If your lot falls inside a Provincial Transit-Oriented Area (around SkyTrain stations and major bus exchanges), the SSMUH rules don't apply - those lots are governed by higher-density transit-oriented rules that typically allow far more than 6 units. Run your address to see which framework applies to you.
