What Is Small-Scale Multi-Unit Housing, and Does It Apply to My North Shore Lot?
BC's small-scale multi-unit housing rules let 3 to 6 homes onto lots that used to allow only one. Here's what the rule actually says and how to check your own North Shore property in about ten minutes.
“• Small-scale multi-unit housing, or SSMUH, is a provincial rule (Bill 44, tightened by Bill 25 in late 2025) requiring BC municipalities over 5,000 people to allow more than one home on lots that used to be single-family only
• Lots under 280 square metres can now hold up to 3 units; lots 280 square metres or larger can hold up to 4; lots near frequent bus service can hold up to 6, with no minimum parking required
• All three North Shore municipalities have to comply, though each is handling the rollout on a different timeline and in a different way
• Checking whether your own lot qualifies takes about ten minutes with your municipality’s zoning map and a bit of arithmetic”
What SSMUH Actually Requires
Small-scale multi-unit housing is the province's shorthand for a rule most homeowners have heard about in passing but haven't actually read. The short version: the BC government passed legislation, known as Bill 44, that requires every municipality with more than 5,000 residents to update its zoning bylaws so that lots previously restricted to a single detached house can now hold multiple homes, things like a duplex, triplex, or small multiplex, without the owner needing to apply for a rezoning first. In November 2025, the province passed a follow-up law, Bill 25, that tightened and clarified how that original rule gets applied.
Here's the part that actually matters if you own a lot: the number of units you're allowed depends on your lot's size and how close it sits to frequent transit. A lot under 280 square metres can now host up to 3 units, think a house with a secondary suite and a garden suite. A lot of 280 square metres or larger can host up to 4 units. And if your lot sits within about 400 metres of a bus stop with frequent service (roughly every 15 minutes during the day, both on weekdays and weekends), it can host up to 6 units, and municipalities can't require you to add parking for them.
That last piece surprises a lot of owners: the province defines "frequent transit" specifically, not just "near a bus route." It has to be a stop where a bus actually shows up every 15 minutes or so through most of the day, which on the North Shore mostly means the busier corridors rather than every residential street.
How to Actually Check Your Own Lot
This part is more mechanical than most zoning questions, which is good news. Three things to look up:
Your lot's zoning designation. Your municipality's online zoning map will show whether your property sits in a zone that's already been updated for SSMUH. Some municipalities have built dedicated lookup tools for exactly this question, which are faster than reading a zoning bylaw PDF cover to cover.
Your lot's size. This determines the 3-unit versus 4-unit threshold and is usually listed right on the same zoning map or in your property's BC Assessment record.
Distance to a frequent transit stop. This is the piece most owners haven't checked, and it's the one that can bump you from 4 units to 6.
All three North Shore municipalities are required to comply with SSMUH, but they're not all at the same point in adopting it, and the differences matter more than the province's baseline rule does if you're trying to figure out your own lot's actual status right now. I've written up how the City of North Vancouver, the District of North Vancouver, and West Vancouver are each handling the rollout differently, since the local details are moving faster than most people expect.
If your address is anywhere near a bus corridor or you're not sure how your specific lot has landed, your municipality's planning department will confirm it directly, and it's worth the phone call before you assume anything either way.
What This Means for You
Qualifying for more units doesn't mean you have to do anything with that. Most owners I talk to have no interest in redeveloping their own home, and that's completely fine. What it does mean is that your lot's underlying value to a future buyer, particularly a builder, may be different than it was a year or two ago, and that's worth knowing even if you're nowhere near ready to sell. It can also shift how a property's assessed and market value get talked about, since redevelopment potential is one of the things that separates a lot's land value from what the existing house alone would fetch. If you're weighing where to buy with a family in mind, added density is one more factor sitting alongside the broader North Vancouver versus West Vancouver trade-offs worth thinking through before you commit to a neighbourhood.
None of this calls for a fast decision. Zoning potential is one input among several, and it sits alongside your own timeline, your lot's physical constraints, and where the market happens to be when you're ready to act.
If You Want a Second Set of Eyes on This
If you're not sure how your own lot has landed under these rules, or you're weighing a purchase where redevelopment potential is part of the appeal, send me your address and I'll take a look with you, no pressure, just a clear read on where things actually stand.
