How many homes can you build on a BC lot?

It applies if your lot is in a single-family or duplex zone, inside your community’s urban containment boundary, in a municipality with more than 5,000 people. If all three are true, your city must allow small-scale multi-unit housing on your lot. Rural areas, very small municipalities, and land outside the urban containment boundary are generally not covered. The provincial rule sets the floor; your city’s bylaw carries the detailed standards.

It depends on your lot size and your distance to frequent transit. The minimum is 3 units on a lot of 280 square metres (about 3,000 square feet) or smaller, and 4 units on a lot larger than 280 square metres. If your larger lot is near frequent bus service, the city must allow 6 units. These are minimums the province sets. A city can allow more, but it cannot allow less.

280 square metres, which is about 3,014 square feet. At or below that size the provincial minimum is 3 units; above it the minimum is 4. Because so many BC lots are larger than 280 square metres, 4 units is the baseline for a large share of single-family properties in the province.

Frequent transit means a bus route where a bus stops on average every 15 minutes or better, during set daytime hours on weekdays and weekends. If your lot is larger than 280 square metres and sits close to that kind of service, the city must allow up to 6 units. This is the same logic other reforms use: more homes where transit can carry the people who live in them.

Within 400 metres of a qualifying frequent-transit stop, the province tells cities they cannot require off-street parking for small-scale multi-unit housing. Outside that band, parking rules are set by your city. Removing the parking requirement is one of the biggest changes in practice, because a required parking pad often crowds out the fourth or sixth home on a narrow lot. Confirm the exact rule with your municipality, since the 400-metre detail is set in provincial policy guidance.

Most municipalities over 5,000 updated their bylaws by the original June 30, 2024 deadline, and the province required a further update by June 30, 2026 to match the Bill 25 clarification. If your city is behind, the provincial rules still describe what must be allowed, so it is worth checking your city’s zoning bylaw and the province’s SSMUH page together. A city that has not fully complied can still be required to follow the provincial floor.

Bill 25, passed in 2025, tightened the definition of a “restricted zone.” It clarified that if a zone contains even one lot limited to a single detached house or a duplex, the whole zone must meet the minimum-unit rules on every lot. This closed a loophole where some cities argued a mixed zone was exempt. Cities had until June 30, 2026 to bring their bylaws in line with this clarification.

It is meant to be as of right, meaning you do not need a rezoning or a public hearing to build the units the province requires. The use is permitted in the zone. You still need a building permit and must meet your city’s detailed standards for height, setbacks, and design. The point of SSMUH was to remove the slow, uncertain rezoning step for small projects, so an ordinary owner can build a few homes without a political fight.

The provincial rule sets minimum unit counts; whether you build for ownership as strata or as rental is generally your choice, subject to your city’s detailed rules. Some cities, including Vancouver, offer more floor area if you commit the building to rental, which can change the math toward more units. Check your municipality’s bylaw, because the ownership-versus-rental incentives are set locally on top of the provincial floor.

The province sets a floor: the minimum number of units a city must allow. Your city then writes the detailed rules for how big the building can be, how tall, how far from the property line, and how it must look. So two lots with the same provincial minimum can end up building very different projects depending on the city’s floor-area and design rules. The floor is the same across BC; the ceiling is local, and it is usually the local rules that decide what actually gets built.

The honest answer is that a clear province-wide count of homes built under SSMUH is not yet published. The rule is new, and the strongest data so far is city-specific rather than provincial. Vancouver, for example, has thousands of multiplex units in application but far fewer finished. It is fair to say the legal right now exists across the province, but building lags the legalization, which is the pattern in almost every reform on this hub.

SSMUH (Bill 44) covers small-scale housing of 3 to 6 units on ordinary residential lots across the province. A separate law, Bill 47, sets “transit-oriented area” rules that allow taller apartment buildings close to rapid-transit stations and major bus exchanges. They work together: SSMUH lifts the floor everywhere, while the transit-oriented rules allow much higher density in a tight radius around major transit. For most single-family lots, SSMUH is the rule that applies.

BC’s mandate is among the most ambitious anywhere: a whole province forcing 3 to 6 homes onto single-family lots, scaled by transit, with no city opt-out. It most resembles Washington State’s HB 1110 and New Zealand’s national MDRS. The open question is not ambition but durability and real uptake: whether BC ends up like Auckland, where homes actually got built and rents softened, or like the reforms where the right existed on paper but little was built. That is decided lot by lot.
