What BC's landmark housing legislation means for buyers, investors, and existing multi-family property owners — which cities it applies to, what you can build, and what to ask before you buy.

Small-Scale Multi-Unit Housing (SSMUH) refers to BC's November 2023 legislation — formally Bill 44, the Housing Statutes (Residential Development) Amendment Act — that requires municipalities to allow a minimum of 3 to 6 residential units on lots previously zoned for a single-family or duplex home.
The legislation was introduced in response to BC's severe housing shortage. For decades, local zoning bylaws restricted most residential land to single-family use, preventing gentle intensification even on large lots steps from transit. By mandating multi-unit zoning across the province, the BC government aims to increase housing supply without requiring large-scale rezoning campaigns or developer applications.
SSMUH doesn't force anyone to build — it removes the bureaucratic barrier to building. A lot owner can still maintain their single-family home as-is. The legislation simply means they no longer need to apply for rezoning to add legal secondary suites, a carriage house, or a fourplex.
All BC municipalities with populations over 5,000 were required to comply with SSMUH by June 2024. For buyers in Metro Vancouver, this covers every major city in the region:
3–6 units on most RS zones, up to 6 near transit
3–4 units on most R1/R2 lots
3–4 units, varies by lot size
3–4 units, lot size minimums apply
4 units on most residential lots
3–4 units, rural areas may differ
3–4 units by right
3–4 units, heritage lots exempt
3–4 units on standard lots
Compliant but has stricter local rules
Each municipality implements SSMUH differently — always verify the specific rules (setbacks, height, lot coverage) with the municipality or a licensed designer before purchasing a lot for multi-unit development.
"By right" means that a property owner is permitted to build a specified number of units without needing to apply for rezoning — the most time-consuming and uncertain part of any development process. Under SSMUH, up to 4 units are allowed by right on most residential lots; up to 6 units are allowed on lots that are:
The 4 (or 6) units can take many forms, depending on site constraints:
By right means no rezoning — but it does not exempt you from building permits, development permits, Development Cost Charges (DCCs), or compliance with building codes. You still need to go through the city's normal permitting process. By-right simply means the land use is already approved; the specific project still needs its own permit.
SSMUH opens a compelling new investment strategy: purchasing a modest single-family home on a qualifying lot, retaining or renting the existing house while obtaining permits to add additional units, and gradually building a multi-unit rental portfolio without commercial financing. This "buy, hold, and add" approach is now viable in cities that previously required expensive rezoning applications.
Existing multi-family properties — particularly older duplexes and fourplexes — still deliver reliable rental income. However, SSMUH creates new competition from freshly built multi-unit properties on previously single-family lots. The net effect on value depends on your specific property:
If you are selling a duplex or fourplex on a large lot in a qualifying SSMUH municipality, the redevelopment potential is now a legitimate selling point. Have your agent quantify the density potential — how many units could be built under SSMUH — and include that analysis in your marketing materials.
Before purchasing a property specifically to leverage SSMUH density, due diligence requires more than checking the zoning. Ask the following:
Commission a pre-purchase feasibility letter from a licensed architect or residential designer. For $500–$1,500, they can tell you exactly what can be built on the lot, what permits are required, and a rough cost estimate. This is money well spent before a $1.5M+ purchase.
The impact of SSMUH on property values is nuanced and continues to evolve as the market digests the legislation. Here is what the current data and experience suggest:
Lots that are large enough to support the maximum allowable density under SSMUH are being priced at a premium relative to smaller lots in the same area. Buyers are essentially purchasing an option on future development. This is most visible in Burnaby and Vancouver where 33' × 122' lots near SkyTrain have seen increased investor interest.
Well-maintained duplexes and fourplexes with legal suites, good parking, and current electrical (200-amp panels per unit) continue to trade at strong multiples. Buyers who want rental income today — without the 12–24 month permitting and construction cycle — pay a meaningful premium for turnkey income properties.
Older multi-family properties in poor condition, with non-permitted suites, outdated wiring, or deferred maintenance may become relatively less attractive as SSMUH makes new-build alternatives easier. Sellers of these properties need realistic pricing expectations in 2025 and beyond.
SSMUH stands for Small-Scale Multi-Unit Housing. BC’s Bill 44 (November 2023) requires all municipalities with populations over 5,000 to allow a minimum of 3 to 6 residential units on lots previously zoned for single-family homes — without requiring rezoning applications. The goal is to rapidly increase housing supply across BC by enabling gentle densification on existing residential land.
All BC municipalities with populations over 5,000, including Vancouver, Burnaby, Surrey, Richmond, Coquitlam, Abbotsford, Langley, New Westminster, North Vancouver, West Vancouver, and Victoria. Each city implements its own rules for setbacks, height, and lot coverage within the provincial minimums.
"4 units by right" means that on a standard residential lot in a qualifying municipality, a property owner can build up to 4 residential units — duplexes, triplexes, fourplexes, carriage houses — without applying for rezoning. Sites near frequent transit can support up to 6 units. By-right approval removes the rezoning step but does not eliminate the need for building permits, development permits, or Development Cost Charges.
Yes, in multiple ways. Larger lots with redevelopment potential are seeing premiums from buyers who value the density optionality. Well-maintained income properties with legal suites retain strong values because they produce rental income immediately, without going through permitting. Older, poor-condition properties face pricing pressure as new-build alternatives become easier under SSMUH.
Key questions: (1) Has the municipality updated zoning to comply with SSMUH? (2) What is the maximum density — 3, 4, or 6 units? (3) What are the setback, height, and lot-coverage rules? (4) Does existing water/sewer infrastructure support multiple units? (5) Is parking required, and is there room for it? (6) What are the Development Cost Charges per added unit? Have a licensed architect provide a feasibility assessment before purchase.
Not on every lot. Site-specific constraints — lot size, setbacks, lot coverage maximums, height limits, and servicing capacity — determine what is actually buildable. SSMUH removes the rezoning barrier but doesn't override other municipal rules. Always commission a site-specific feasibility assessment before purchasing specifically for SSMUH development.
Near frequent transit, municipalities cannot require more than one parking stall per unit and cannot require any parking close to frequent bus stops. Away from transit, parking requirements vary by municipality. In practice, many urban Metro Vancouver lots will have reduced or eliminated parking minimums under SSMUH — which increases buildable density but can affect tenant demand from car-owning renters.
