BC’s New Zoning Rules Explained: What You Can Actually Build on Your Lot Now

BC’s New Zoning Rules Explained: What You Can Actually Build on Your Lot Now

Since the province passed Bill 44 in late 2023, most single-family lots in BC’s larger urban areas, Surrey, Burnaby, and Vancouver included, are no longer restricted to just one home. The rules are collectively known as Small-Scale Multi-Unit Housing (SSMUH), and they set a province-wide minimum for how much density a municipality has to allow, even if the local zoning map still says “single-family.” That’s a real opportunity for homeowners sitting on an ordinary lot, but the actual number of units you can build depends on specifics that are easy to get wrong from a quick search. Here’s how it actually breaks down.

What the province actually requires

SSMUH applies to municipalities with more than 5,000 people, which covers Surrey, Burnaby, Vancouver, and most of Metro Vancouver. It sets a floor, not a ceiling: cities can allow more density than the province requires, but they can’t zone a qualifying single-family lot down to one unit anymore. The baseline looks like this:

“Frequent transit” has a specific meaning here: a bus or SkyTrain stop with service roughly every 15 minutes through most of the day, not just any bus route. That distinction is exactly why two lots that look identical from the street can qualify for very different unit counts.

Parking rules changed too, and this is the part people miss

What still depends on your specific lot and city

The province sets the minimum, but each municipality has been rolling its own bylaws, design guidelines, and application processes out on its own timeline, and Surrey, Burnaby, and Vancouver don’t all handle the details the same way. Before assuming a number, it’s worth confirming:

• Whether your lot actually falls within the urban containment boundary the rules apply inside, generally not to larger rural or acreage-style properties.
• Whether you’re inside a designated frequent transit area a few hundred metres can be the difference between a 4-unit and a 6-unit allowance.
• What your city’s own design guidelines require setbacks, height, and site coverage rules still apply on top of the unit count, and they vary by municipality.
• Whether services can support it sewer, water, and drainage capacity are checked at the application stage, and older infrastructure in some neighbourhoods can limit what’s realistic even where zoning allows more.
• Any existing restrictive covenants these can still override the new zoning on a specific title.

We covered how to weigh unit count once you know what’s allowed in our duplex vs. multiplex breakdown, this article is really about the step before that: confirming what your lot is actually entitled to build in the first place.

Why this is worth checking before you commission a design

We’ve seen homeowners come to us with a design already sketched around an assumed unit count, only to find their specific lot qualifies for fewer units than they’d planned, or more than they realized. Either way, that’s a conversation worth having before money goes into drawings, not after. A short zoning and site review upfront, checking lot size, transit proximity, service capacity, and your municipality’s current bylaw, tells you what’s actually realistic for your property before you commit to a design direction.
