Builders and land agents have been working the Township for two years, and the pitch usually arrives as a number. Four units. Six units. A multiplex. Most owners I talk to have no idea whether their own lot qualifies, and a good share of them do not. Here is what the Township's bylaw permits as of October 2026, from its own report to Council and its small-scale multi-unit housing page.
The two tiers, and why they are maximums here
Small-scale multi-unit housing, SSMUH for short, is the provincial requirement that municipalities permit more than one home in zones that used to allow a single house or a duplex. The province set floors. On a parcel of 280 square metres or less, 3,014 square feet, a minimum of three units. On anything larger, a minimum of four.
The Township adopted its Zoning Bylaw amendments on November 18, 2024, under Bylaw No. 6020. It took the provincial floors and wrote them in as maximums. Three units on lots of 280 square metres or less, four units on lots above that. The staff report to Council says so in its own comparison table: the province's figures are a minimum, the Township's are a maximum. Single family houses are still permitted in all of these zones.
The six unit claim
This is where most of what is written about Langley goes wrong. Provincial law does require six units, but only on a parcel larger than 281 square metres that sits wholly or partly within 400 metres of what the regulation calls a prescribed bus stop. A prescribed bus stop is one served by at least one route scheduled to stop every 15 minutes on average between 7 am and 7 pm on weekdays, and between 10 am and 6 pm on weekends.
The Township's June 10, 2024 report to Council dealt with that directly. Six units must be permitted where bus frequency meets the Provincial Policy Manual, and in the Township there are no locations that meet the threshold. That is the Township's own analysis, and its SSMUH page still lists only the three and four unit tiers in October 2026. So a listing or article telling you a Langley lot near frequent transit can hold six is describing provincial law, not the bylaw that governs your property. Service levels do change, and the provincial manual expects municipalities to revisit this at the next planning update in 2030, so ask staff rather than assume.
Servicing decides eligibility, and it splits by neighbourhood
A lot has to clear six tests. It has to be inside the Urban Containment Boundary, connected to both municipal water and municipal sewer, free of a heritage designation by bylaw, outside a Transit Oriented Area, no larger than 4,050 square metres, and in a zone whose own minimum lot size is not larger than 4,050 square metres.
Water and sewer is the test that fails most often, and it does not fail evenly. The Township estimated that about 55 per cent of its single family and duplex lots, roughly 15,000 properties, would qualify for three or four units. Close to all of Walnut Grove and Murrayville qualify, 99 and 98 per cent. Brookswood sits at 15 per cent and Fort Langley at 22 per cent, both on servicing. Two houses worth about the same, one in Walnut Grove and one in Brookswood, can have opposite answers.
A lot that fails any of the tests is zoned for one dwelling unit plus a secondary suite or an accessory dwelling unit, depending on zoning. Still more than it carried before. A long way from four.
A bigger lot can get you less
The acre ceiling catches people. 4,050 square metres is almost exactly one acre, and a parcel above it is not eligible at all. Neither is a lot in a zone whose subdivision minimum is over an acre. Owners of large properties assume more land means more units. Here it runs the other way.
Willowbrook is its own case. On May 2, 2025, a provincial Order in Council designated the 800 metre radius around the proposed Surrey to Langley SkyTrain station on 196 Street as a Transit Oriented Area. Properties inside it are excluded from SSMUH, and in exchange the minimum allowable density runs from 3.0 floor area ratio and eight storeys at 400 to 800 metres out, up to 5.0 and twenty storeys within 200 metres. That is a different conversation than a fourplex, on a different timeline.
What four units looks like on a Langley lot
The province recommended 50 per cent lot coverage. The Township kept its existing maximums, 35 per cent in the standard R zones, and allows 45 per cent where the existing house is retained. Its own analysis produces the most useful figure in the report: on larger lots at 35 per cent coverage, four units of 82 to 105 square metres each, 880 to 1,128 square feet. Parking is one space per unit with a minimum of two per lot. Height stays at 9 metres, and front loaded lots have a maximum front setback of 7.5 metres, written in to stop principal dwellings being pushed to the rear with the front yard turned over to parking.
The staff report is candid that parking will be the key challenge, and that on street parking will absorb the shortfall. Four units of around 1,000 square feet with two parking spaces between them is the product.
The step that was added in April
On April 27, 2026, Council adopted Schedule 4 of the Official Community Plan, Bylaw No. 6116, creating a development permit area with form and character guidelines for SSMUH. A development permit is now required unless the project meets the conditions for an exemption. Most are decided by staff rather than Council, though three of the nine Council members can pull a project to the table. The guidelines cover details like a paved path to each unit's door and light reaching every unit from two sides.
Development cost charges apply to each SSMUH unit, except a secondary suite inside a single family home, because the single family rate already includes one. Where servicing capacity is not there, the upgrades are set under the Subdivision and Development Servicing Bylaw and have to be finished before a new connection is provided.
What this does to your number
Zoning permission is not land value. Langley's detached benchmark price was $1.471M in September 2026, down 6.7 per cent year over year, on 64 sales against 449 active listings. That is a sales to active ratio of 14 per cent, the low end of balanced. A builder choosing between a Langley fourplex site and waiting is running that arithmetic too, and servicing risk comes off the price of the land.
Three questions decide whether your lot trades above its value as a house. Whether municipal water and sewer both front it. Whether it sits between 280 and 4,050 square metres and can hold four units and their parking. And whether what fits is something a builder wants to build at current prices. An unsolicited offer is usually priced as though all three are yes, with the risk left sitting with you.
If you own in Langley
Start with servicing. The Township's Community Development Division will tell you whether municipal water and sewer front your property, and that answer moves your number more than the zoning does. In Walnut Grove or Murrayville it is usually yes. In Brookswood it usually is not, and the Brookswood-Fernridge Community Plan post covers why. For acreage, or anything in the Agricultural Land Reserve, read Fort Langley acreage and the ALR instead, because SSMUH is not what governs it.
I can tell you what your lot is designated for, what has sold nearby on a land basis, and what your property is worth as a house rather than as a development site. Start with what your Langley home is worth, or see what a Langley realtor is seeing across the Township.
