SSMUH in Surrey: How the City Is Applying the New Density Rules

Surrey applies Bill 44 by letting most former house and duplex lots hold 3, 4, or 6 homes without a rezoning. The count turns on lot size and whether the parcel sits in a Frequent Bus Stop Area mapped in Schedule F of Zoning Bylaw 12000. A lot under 280 m2 (3,014 sq. ft.) is capped at 3 units. A larger eligible lot is capped at 4, or at 6 if it is at least 281 m2 and inside that frequent-bus overlay.

Council adopted the rewrite on July 8, 2024. The City folded about 20 single-family, duplex, and gross-density zones into nine new small-scale zones and applied them to more than 72,000 lots inside the Metro Vancouver Urban Containment Boundary. About 13,000 of those lots, roughly 18 percent, sit in Frequent Bus Stop Areas where six units and no off-street parking minimum are on the table. That is a different map from a Surrey home search that still reads as one house on title.

You do not have to build the extra homes. A single detached house remains legal. What changed is the floor the zoning bylaw must allow, plus the form rules Surrey wrote on top of that floor.

How Surrey translated Bill 44 into Zoning Bylaw 12000

Bill 44, the Housing Statutes (Residential Development) Amendment Act, 2023, forced municipalities over 5,000 people to permit 3, 4, or 6 units on restricted residential lots. Local governments had until June 30, 2024 to rewrite zoning. Surrey met that deadline with Corporate Report R109 and a full replacement of Parts 12 to 18 of Zoning Bylaw 12000.

According to the City of Surrey, the Province defines small-scale multi-unit housing as a range of buildings that can deliver more attainable homes for middle-income families. The local bylaw then decides which combination is legal on which lot. Surrey chose consolidation instead of leaving the old RF, RF-12, and RH labels in place.

The practical result is a new zone letter on COSMOS, not a blank cheque. Setbacks, height, lot coverage, lane access, and parking still decide whether four units fit. A Frequent Bus Stop Area lot and a quiet cul-de-sac lot do not pencil the same.

The unit table Surrey is using

The provincial 3 / 4 / 6 floor is the starting line. Surrey wrote it into each new zone and then added location tests.

A prescribed frequent stop is not every bus pole on King George or Fraser Highway. Schedule F lists the lots that sit wholly or partly within 400 metres of a stop with 15-minute average service. Confirm the overlay on the City mapping tool at surrey.ca/ssmuh before you treat six units as a given on a first-time buyer offer.

The nine zones that replaced the old house labels

Surrey did not keep RF, RF-12, RF-9, RH, and RQ as living zone names. Those labels were grouped by lot size and replaced. Gross-density and duplex zones were then assigned to one of the new labels based on the actual parcel area.

Specialist labels still exist beside that core set. RF-O oceanfront lots became R2-O. RF-9S and RF-10S became R5-S. Semi-detached RF-SD lots became R6. More than 4,600 Comprehensive Development lots kept their CD zone. Part 52 of the bylaw then adds SSMUH permissions to those CD lots by lot size instead of forcing a map change.

If the listing still says RF, treat that as history. Pull the current zone on COSMOS and read the matching part of Bylaw 12000. The old brochure language will not tell you whether a houseplex is even a legal form.

Where six units and zero parking actually apply

Six units are not a citywide default. They attach to eligible lots between 281 m2 and 4,050 m2 that sit wholly or partly inside a Frequent Bus Stop Area. The City puts that overlay at about 13,000 lots, or 18 percent of all SSMUH lots.

Inside that overlay, Sections 481.3(5) and 525(1.1) of the Local Government Act remove the off-street parking and loading minimum for the residential SSMUH use. Outside the overlay, the zone parking table still applies. A draft City summary used two spaces per principal unit and one space per accessory unit as the starting point for those other lots.

That split shows up on the ground in Fleetwood and along Fraser Highway RapidBus more than it does on a quiet Newton cul-de-sac. A buyer who prices six lock-off suites on a lot with no Schedule F shading is counting density the bylaw does not give.

The R3 houseplex rule Surrey added on top of the provincial floor

A houseplex is Surrey's name for a building that looks like a large house and holds three or four principal units. The City limited that form to the R3 Urban Residential zone. Most former RF lots now sit in R3, but not every R3 lot can take a houseplex.

According to the City of Surrey houseplex permit page, the lot must have rear lane access or two street frontages as a corner or through lot, and it must sit outside a Transit-Oriented Area. The minimum building width is 15 metres, which typically needs an 18-metre lot. Parking must sit in a detached garage or pad, not in an attached garage. Secondary suites are not permitted inside a houseplex.

Six units on an R3 frequent-bus lot therefore usually mean a four-unit houseplex plus two coach houses, not a fourplex stuffed with basement suites. Corporate Report R109 listed that coach-house combination when Council adopted the framework. Width, lane, and the no-suite rule are what knock a lot out of the six-unit pencil before parking even enters the file.

What Surrey carved out of the SSMUH map

The new density does not blanket the whole city. The 3-to-6 table applies to lots under 4,050 m2 inside the Metro Vancouver Urban Containment Boundary. Several statutory and local carve-outs then pull parcels back off that table.

•       Transit-Oriented Areas around SkyTrain stations and bus exchanges, which follow Bill 47 density and height floors instead.

•       Lots larger than 4,050 m2, and zones whose minimum subdivision size is 4,050 m2.

•       Lots not connected to municipal or regional water and sewer.

•       Heritage land protected under the Heritage Conservation Act, or designated under a Local Government Act heritage bylaw as of December 7, 2023.

•       Lots subject to a hazardous condition that makes the extra units unsafe.

•       Section 219 Land Title Act covenants that restrict housing. The City states those covenants still apply and take precedence.

Whalley and City Centre buyers run into the TOA carve-out most often. A lot two blocks from King George Station is not a sixplex candidate under SSMUH. It is a Bill 47 parcel with a different height and floor-space conversation.

What has actually been built so far

The zoning change is two years old. The building pipeline is still thin relative to 72,000 eligible lots, and it is skewed toward duplexes rather than six-unit houseplexes.

City reporting tied to the July 27, 2026 review put approved SSMUH activity at 465 building permits and 943 net new dwelling units. Of those extra homes, about 71 percent were duplexes, 22 percent were garden suites or coach houses, and 7 percent were houseplexes. An earlier October 14, 2025 Development Approval Process Improvement Task Force update had counted 138 additional SSMUH units and $4 million to $4.5 million in servicing connection costs.

The construction-value report for the first half of 2026 then recorded a 34 percent rise in new single-family dwelling units versus the same period in 2025, which staff tied to a surge in SSMUH permits for coach houses, garden suites, and duplexes. That is infill on existing streets, not a sudden fourplex skyline in Newton.

The July 2026 review and the servicing bill

On July 27, 2026, Council approved a comprehensive review of SSMUH regulations and implementation under Corporate Report R162. The July 8, 2024 zoning remains in force while staff look at neighbourhood fit, parking, addressing, building requirements, and engineering.

The same report is where servicing costs moved from a quiet permit condition to a Council issue. Engineering flagged about 260 kilometres of small-diameter water main and 100 kilometres of small-diameter sanitary sewer that could need upsizing over 40 to 50 years, at an estimated $820 million to $870 million if the City rather than the applicant paid. Staff answered with a tiered frontage package: road dedication on arterial and collector frontages, sidewalks on fronting and flanking streets, local-road works on duplex and houseplex files, and laneway upgrades on houseplex files.

Those conditions can change the budget faster than the unit count. A garden suite on a finished street is a different file from a four-unit houseplex that triggers curb, boulevard, lane drainage, and a sewer upsize from 150 mm to 200 mm. Ask for the current engineering checklist before you treat extra doors as free equity.

What a Surrey buyer should verify before pricing density

SSMUH is a zoning minimum, not a financed project. Lenders still haircut suite income, and a spec fourplex is underwritten differently from a house with one legal suite. Walk the numbers on the financing page before you bid as if four rents were already in place.

•       Confirm the current zone and Frequent Bus Stop Area shading on the City SSMUH map and COSMOS, not on an old listing sheet that still says RF.

•       Read the title for section 219 covenants, easements, and statutory rights of way. Zoning permission does not override a covenant that bans a second dwelling.

•       Measure lot width and check for a lane or second frontage if the plan is a houseplex. An R3 label alone is not enough.

•       Separate SSMUH lots from Transit-Oriented Area lots. A SkyTrain walk-shed follows Bill 47, not the 3-to-6 table.

•       Price servicing, trees, and development permit areas. Steep slope, floodplain, and sensitive ecosystem DPAs still apply and cannot unreasonably block the mandated density, but they can add drawings and time.

•       Treat extra units as optional. If the use case is one home and a future suite, shop the home buying process the same way you would for any other Surrey house, then layer density only after the title and map agree.

Langley is not a substitute checklist. The Township has no six-unit frequent-bus tier on the same terms, and the City of Langley rebuilt a different code. If you are comparing a Clayton R3 lot with a Willoughby house lot, start with the Langley page and the local bylaw, not a single Fraser Valley rule of thumb.

FAQ

How many units can I build on a Surrey lot under SSMUH?

On an eligible lot inside the urban containment boundary and under 4,050 m2, Surrey permits a maximum of 3 units on a parcel smaller than 280 m2, 4 units on a larger parcel, and 6 units on a parcel of at least 281 m2 inside a Frequent Bus Stop Area. Confirm the address on the City map before you price that number into an offer.

Is every former RF lot allowed a houseplex?

No. Houseplexes are permitted only in the R3 zone, and only on a lot with rear lane access or two street frontages. The City requires a 15-metre building width, which typically needs an 18-metre lot. Secondary suites are not permitted inside a houseplex.

Do I need parking for extra units in Surrey?

Not if the lot sits wholly or partly in a Frequent Bus Stop Area. About 13,000 lots, or 18 percent of Surrey SSMUH lots, have no off-street parking minimum for that residential use. Outside the overlay, the zone parking table still applies.

Does SSMUH apply next to a SkyTrain station?

No. Land inside a designated Transit-Oriented Area is exempt from the SSMUH 3, 4, and 6 unit table. Those parcels follow Bill 47 density and height floors around SkyTrain stations and bus exchanges.

Can a title covenant block the extra units?

Yes. The City of Surrey states that existing section 219 Land Title Act covenants that restrict housing still apply and take precedence. Order a title search before you treat four or six units as automatic.

Has Surrey started changing the rules again?

The July 8, 2024 zoning is still the rule set in force. On July 27, 2026, Council approved a full review plus updated servicing requirements. If you want a second set of eyes on a specific address, book a consult before you lock a construction budget or write a subject-free offer.
