The single-family lot as most people picture it (one house, maybe a basement suite) is quietly becoming a thing of the past across much of British Columbia. A provincial law called known as Bill 44 has rewritten what you’re allowed to build on a huge number of residential lots across the province. If you own a home, you may be sitting on far more possibility than the house on it suggests.
Here’s the plain-language version: what changed, what it means for your lot, and — just as important — what stands between “allowed” and “built.”
What is ‘SSMUH’?
SSMUH stands for Small-Scale Multi-Unit Housing. It came out of the province’s Bill 44 in 2023 and was sharpened by Bill 25 in 2025. In plain terms, the province told most municipalities to stop reserving residential neighbourhoods for single-family houses, and to allow more ‘gentle density’ homes — secondary suites, garden suites, laneway homes, townhouses, and small multiplexes — on lots that used to permit only one or two.
The idea of gentle density is one way to address the housing crisis: more homes in the neighbourhoods we already have, close to the schools, shops, and transit that are already there — without reaching for high-rises.
This approach keeps property taxes low while allowing communities to upgrade infrastructure. In exchange, homeowners have the opportunity to add more housing (for themselves, renters, or others) in areas where only single-family homes were previously allowed.
What you can actually build
How many homes you can build comes down mainly to two things: how big your lot is, and how close it is to frequent transit. The province set minimums that municipalities have to allow — they can allow more, but never less:
- A secondary suite (and in most cases a detached unit like a garden or laneway suite) is now allowed alongside a single-family home in communities across BC.
- On a typical lot in a municipality of 5,000 or more people: 3 units on smaller lots (up to 280 m²) and 4 units on larger lots (over 280 m²).
- On a larger lot near frequent transit — over 280 m² and within 400 metres of a bus stop served roughly every 15 minutes through the day: up to 6 units, with no minimum parking required.
In practice, those units can be a mix. A main house, a basement suite, and a laneway home together make three; a purpose-built fourplex is four. What matters is that the combination stays within the total your lot allows.
Here’s the part that surprises people most: for a project that meets the rules, this is as-of-right. No rezoning, no public hearing, no discretionary approval.
If your design meets the objective standards in the bylaw, the municipality has to allow it.
What SSMUH doesn’t change
SSMUH sets a floor for density — it isn’t a free pass. Several things still apply:
- The rest of the rulebook. Height limits, setbacks, lot coverage, and the BC Building Code all still inform your design.
- Servicing. The added density is only allowed on lots connected to municipal water and sewer (not well and septic.)
- Protected land. Environmentally sensitive areas, agricultural land (the ALR), and heritage properties keep their existing protections and may carry extra requirements.
- Old suites aren’t auto-legal. An unpermitted basement suite doesn’t become legal just because the zoning changed — you still need permits and code compliance to bring it onside.
From “allowed” to “built”
So you have the rights. What’s the path from there?
Roughly four steps:
- Confirm what your lot allows. Check your municipality’s current zoning for your specific address — lot size, transit proximity, and the local site standards decide your real number.
- Test feasibility. Can the lot physically and financially carry the units? This is where servicing, site constraints, and budget come in — and where projects most often end up smaller than the zoning would allow (more on this in a later blog.). You’ll want to look at market sale prices, rental rates, and compare them with the cost of construction in your community.
- Design it. A good design hits your unit target while keeping the homes efficient, comfortable, aligned with your budget, and a good fit for the street.
- Permit and build. With a compliant design you’re on the as-of-right path — no rezoning — but still working through building permits and construction.
The bottom line
The headline is genuinely good news. Across BC, ordinary lots now carry building rights they simply didn’t have a few years ago, and gentle density is no longer a fight you have to win one lot at a time.
This shift opens real options for homeowners who want to add a suite for family, create rental income, or help a neighbourhood grow without losing what makes it feel like home.
But “allowed” does not mean “easy,” and the space between the two is where most people get stuck.
That’s exactly the gap Small Housing works to close. With plain-language guidance, resources, and tools that help you get from an idea to a plan you can actually build.
