BC Housing Laws Explained — Part 2: Can You Really Build 6 Homes on One Lot?
This is the question I get more than any other since Bill 44 passed: "Can I actually put six homes on my lot?" The honest answer is — maybe, and it depends on three things: your lot size, your municipality, and whether you're close to frequent transit.
This is Part 2 of the series, and it's the practical one: the actual numbers behind Bill 44. I'll walk through the lot-size rules first, then transit areas, then the exemptions that trip people up — because two properties on the same street can have very different development potential, and most owners have no idea which side of that line they're on.
What Bill 44 actually changed
Bill 44 requires local governments to allow small-scale multi-unit housing across most single-family and duplex zones. The province set the framework; municipalities had to update their bylaws to match it — and how many units apply depends on the specific parcel and its location.
Here's the mental shift I ask clients to make: "single-family lot, single-family use" is no longer the automatic baseline in most BC communities. The new rules set a housing floor, not just a rezoning possibility you'd have to fight city hall for.
The lot-size math, in plain terms
For most eligible parcels: lots at 280 square metres or smaller must allow at least three units. Lots larger than 280 square metres must allow at least four. That's why I tell people to pull out their lot dimensions before they get excited about anything else — the size alone can change your baseline options before design or budget even enter the conversation.
Local variations exist here and there, but the core rule is easy to remember: small lot, three units; standard lot, four units. Lot measurements and servicing capacity should be one of the very first things you check, whether you're evaluating your own property or one you're considering buying.
Transit changes the math completely
Here's where it gets interesting: for lots larger than 280 square metres inside a designated frequent transit area, municipalities must allow a minimum of six units. That's the actual source of the "six homes on one lot" headline you've probably seen.
"Frequent transit" isn't just any bus stop, though — it's tied to a specific provincial definition of high-frequency service, and whether your property qualifies comes down to the local transit-area maps. I've seen two nearly identical lots a block apart land on completely different sides of that line. It's worth checking directly rather than guessing based on "it feels close to transit."
Not every property qualifies — here's what's excluded
Even with rules this broad, there are real exemptions: properties outside municipal servicing areas, very large parcels, certain heritage sites, and some protected or special-designation areas all fall outside the standard framework.
This is exactly why I never let a client stop at the headline number. You need to know whether the lot is serviced, whether it's inside a transit area, and whether any exemption or local condition changes the baseline — because "the law says six units" and "your specific lot allows six units" aren't always the same statement.
What this actually means for you
For homeowners, this creates more redevelopment potential than before — but not automatic redevelopment. Nobody's forcing you to build a fourplex tomorrow. For buyers, the real shift is that a lot is now also a future housing opportunity, not just a place to live today.
That makes due diligence more important, not less. Before you buy or sell, check the actual municipal zoning rules, confirm your lot size, and pull up the province's transit-area map so you know what the current baseline genuinely allows — not what a headline implied.
