How many units can you build on your BC lot?
Most BC municipalities must now permit 3 or 4 homes on lots that were zoned for one house or a duplex. Near frequent bus service the minimum is 6. If you own one of those lots, it may carry more building rights than the house suggests. If you are buying one, the zoning is part of the price.
The three tiers
| Units | Lot area | Distance to frequent transit |
|---|---|---|
| 3 | 280 m² or smaller | Does not matter |
| 4 | Larger than 280 m² | Does not matter |
| 6 | Larger than 280 m² | Within 400 m of a qualifying stop |
The 280 m² (3,014 sq ft) line falls on the three side. A parcel of exactly 280 m² (3,014 sq ft) carries 3. Only a larger one reaches four. The six-unit tier needs both conditions, a lot of at least 281 m² (3,025 sq ft) and a qualifying stop within 400 m.
“Frequent” is defined in B.C. Reg. 262/2023, section 2(4). A route must have a bus at least every 15 minutes on average, 7 a.m. to 7 p.m. Monday to Friday and 10 a.m. to 6 p.m. Saturday and Sunday. Many stops fail the weekend test.
Every figure is a minimum a municipality must permit. It is not a cap and not a permit. Height, setbacks, lot coverage and parking decide what fits. Two of the five municipalities below offer no six-unit tier.
Lots the rules do not reach
For much of British Columbia the exclusions are the answer. The urban containment boundary removes the most land, and explainers leave it out.
Before the unit count — the gates, in order
Three, four and six are the last thing to work out, not the first. A parcel has to clear every test below before any of those numbers is reachable, and the first one it fails ends the exercise. They are listed in the order that costs the least to check.
Start with the Province’s own map. British Columbia publishes the small-scale entitlement parcel by parcel — search an address and it returns what that lot is entitled to. It is the authoritative answer for gates 2 and 3 below and it is free. Find it from the Province’s small-scale housing page.
Two things it will not tell you, and they are the two that end most Fraser Valley projects. It is a snapshot taken when the bylaws landed, so a parcel subdivided or rezoned since can read wrong. And it does not show servicing — whether the lot is on municipal water and sewer, let alone whether there is capacity to connect. That is gate 4, it is not on any map, and it is the rest of this page.
1.Is the municipality inside the Act at all?
Any parcel wholly or partly inside an urban containment boundary set by a regional growth strategy is covered, whatever the size of the municipality. Elsewhere the Act reaches parcels inside a municipality’s own urban containment boundary where the municipality has a population above 5,000.
How to check: Ask the local government whether it adopted a small-scale housing bylaw. If it never had to, there is nothing to apply.
2.Is the parcel inside the urban containment boundary?
This is the test that removes the most land in British Columbia and the one almost every explainer omits. The boundary is a regional growth-management line — in Metro Vancouver it comes from the regional growth strategy, elsewhere a municipality may set one through its Official Community Plan. Outside it, the requirement does not apply, whatever the zoning says. Two neighbours on the same road can land on opposite sides of it.
How to check: The boundary is mapped. Ask planning whether the parcel is inside it before checking anything else — it is a one-question answer and it ends the exercise more often than lot size does.
If it fails: Failing this one is not a dead end. The Province is explicit that land outside the boundary, in zones restricted to single-family use, still has to be allowed a secondary suite or an accessory dwelling unit. That is one home plus one more, rather than three or four — a smaller answer, not no answer.
3.Is the zone a restricted zone?
The rules apply to zones limited to detached houses and duplexes. Bill 25 (2025) widened this: Bill 44’s definition stopped at a house with one extra unit, so a zone that permitted a house plus a suite plus a detached accessory dwelling fell outside. It is now inside. A zone counts as restricted across all of its lots if any parcel in it is limited that way.
How to check: If a lot was assessed in 2024 or 2025 and ruled out on the already-allows-three argument, that answer is worth asking again — the ground moved under it on June 30, 2026.
4.Is the zone’s own minimum lot size 4,050 m² (43,594 sq ft) or less?
A separate question from how big the parcel is, and an easy one to miss. Township of Langley lists both: a property must not be larger than 4,050 m² (43,594 sq ft), and must not sit in a zone whose minimum lot size exceeds 4,050 m² (43,594 sq ft). A modest parcel inside an acreage-minimum zone fails on the second test while passing the first.
How to check: The zone’s minimum lot size is in the zoning bylaw, under the zone the parcel carries. Read the zone, not just the parcel.
5.Is it on municipal water AND sewer?
Both, not either. Land without a connection is outside the requirement, and this is the gate people miss most often locally, because a property can sit on a paved road among ordinary houses and simply not be on municipal sewer. It takes in much of the rural Fraser Valley.
How to check: Confirm with the municipality rather than inferring from the neighbourhood. It is a five-minute question that decides the whole exercise. Two traps the Province spells out: being inside a service area is not enough — the land has to be connected — and a strata’s own on-site water and wastewater does not count, because the system has to be operated by a local government. If a property connects later, the zoning may need updating before the density applies.
If it fails: Same as the boundary: not a dead end. Unserviced land in a single-family zone still gets a secondary suite or an accessory dwelling unit.
6.Is it in the Agricultural Land Reserve?
The Reserve is not on the Act’s list of exclusions, but the Agricultural Land Commission Act overrides any bylaw that permits more than it allows. Reserve land zoned for single-family use must still permit a secondary suite or accessory dwelling unit, and in a limited number of communities the 3-unit minimum can apply. For most Reserve land the Commission’s framework governs, which asks what size of additional residence a parcel may carry rather than how many units it may hold.
How to check: Reserve status is mapped and public. Check it directly rather than assuming from the zoning.
7.Is the parcel 4,050 m² (43,594 sq ft) or smaller?
About an acre. Larger parcels sit outside the requirement — which catches a great many Fraser Valley acreages that are otherwise serviced, urban-feeling and inside the boundary.
How to check: Lot area is on the assessment record and on title.
8.Is it free of a heritage designation or a hazard?
Narrower than it sounds, and the timing is the point. The heritage exemption covers land protected under the Heritage Conservation Act, land designated as protected under section 611 of the Local Government Act on the day the legislation came into force, and heritage revitalization agreements entered into before that day. A property designated since does not escape — the municipality still has to allow the minimum density, and cannot unreasonably restrict it. A heritage conservation area is not on that list at all: it governs form and character, which changes the design and the timeline rather than the unit count.
How to check: Ask planning which of the three, if any, applies — and when it was made. For hazard land the exemption needs a report from a qualified professional certifying both that the hazard exists and that the risk would increase at the permitted density.
The gates are provincial; the thresholds they use are in the Codex entry. Every one of them is a question for the municipality about a specific parcel, and none of them can be settled from a map on a website — this one included.
What changed in 2026: Bill 25
Bill 25 (the Housing and Municipal Affairs Statutes Amendment Act, 2025) received Royal Assent on November 27, 2025. It changed which lots the rules reach. It did not change a unit count or a threshold.
Bill 44 counted a zone as restricted if it allowed only a house, a house plus one extra unit, a duplex, or a duplex plus extras. A zone allowing a house, a suite and a coach house fell outside. Bill 25 brings it in. A zone with any parcel limited to a detached house or duplex is restricted across all its lots.
Bylaws were due by June 30, 2026, unless the Province granted an extension. Where one has not complied, the minister can enact it by order. If a lot was ruled out in 2024 or 2025 because its zone allowed a suite and a coach house, ask again.
Bill 25 also bars a municipality from requiring off-street parking for the units a lot must carry under the six-unit tier. Elsewhere the local bylaw sets parking.
Township of Langley
Read the Township of Langley guide and the Surrey guide for the local answers. For the village, the Fort Langley density year covers the four council votes that put small-scale housing into force at village scale.
Township of Langley adopted its zoning amendments on November 18, 2024, after the June 30, 2024 deadline.
- 3 units on eligible lots of 280 m² (3,014 sq ft) or smaller.
- 4 units on eligible lots from 280 m² (3,014 sq ft) up to 4,050 m² (43,594 sq ft, about one acre). A larger lot is not eligible.
- Parking: at least one space per unit and at least two per lot.
- No six-unit tier appears in the Township’s published guidance. Land in the Willowbrook Transit-Oriented Area is outside these rules.
A lot that fails an eligibility test is not left with nothing. The Township says it is eligible for one home plus one secondary suite or accessory dwelling unit, depending on zoning.
On April 27, 2026 council adopted Schedule 4 of the Official Community Plan. It creates a development permit area with form-and-character guidelines for small-scale housing. A development permit is required unless the project meets the exemption conditions.
Check the live bylaw and zoning map before you rely on this for a lot. Bylaws amend.
Where each Fraser Valley municipality landed
The Province set a minimum. Each council wrote its own bylaw on its own timetable. Two of the five below have no lot that reaches six units.
“Langley” is two municipalities with separate councils and bylaws, and they landed differently. The Township amended Zoning Bylaw 2500 in November 2024. The City of Langley replaced its zoning with Zoning Bylaw 2025, No. 3300, adopted March 9, 2026. The City’s bylaw provides for six units within 400 m of frequent bus service. Check which Langley a property is in first. The addresses interleave along the boundary.
| Municipality | The bylaw | Adopted | Most units | Local detail |
|---|---|---|---|---|
| Township of Langley | Zoning Bylaw 2500, amended in November 2024 | Nov 18, 2024 | 4 | The Township’s page lists three or four units by lot size and describes no six-unit tier. "Houseplex" is Surrey’s word, not the Township’s. |
| City of Langley | Zoning Bylaw 2025, No. 3300 (a complete replacement, not an amendment) | Mar 9, 2026 | 6 | A different municipality from the Township, with a different answer. Permits plexes citywide and carriage homes, and provides for six units within 400 m of frequent bus service. |
| Surrey | Zoning Bylaw 12000, small-scale housing amendments | date not confirmed | 6 | Twenty single-family, semi-detached, gross-density and duplex zones consolidated into nine small-scale zones. Six units where a lot of at least 281 m² sits within 400 m of a prescribed bus stop with 15-minute service. Comprehensive Development lots keep their CD zoning with small-scale permissions added by lot size. |
| Maple Ridge | Zoning Bylaw 7600-2019, amended for small-scale housing | date not confirmed | 6 | Did not create new zones; added an Urban Infill Residential use to the existing ones, so the zone on title is unchanged. Six units on a lot above the 280 m² (3,014 sq ft) line and within 400 m of a stop running at least every 15 minutes, 7 a.m. to 7 p.m. on weekdays. |
| Abbotsford | Zoning regulation and map bylaws, with an Official Community Plan amendment | date not confirmed | 4 | The map bylaw covers properties inside the Urban Development Boundary. No stop currently meets the frequent-service standard. |
Township of Langley and the City of Langley dates come from the municipalities’ own pages. Rows marked “date not confirmed” have not been checked against a bylaw. Confirm any row against the current bylaw and zoning map.
Free provincial designs
The Province publishes free standardized designs: seven concepts for small-scale multi-unit housing and three for accessory dwelling units. Most are building blocks that stack up to three storeys, in duplex, triplex, quadplex and townhouse forms.
They comply with the 2024 BC Building Code and still need adapting to a lot. The Province notes that minor amendments may be required for site conditions.
Investor considerations
- Form versus unit count. Four units as townhouses, as a stacked fourplex, or as a house with a suite and coach house differ in cost, marketability and strata options.
- Stratification. Subdividing under the Strata Property Act lets you sell each unit. It adds strata fees and management, and widens the buyer pool.
- BC home flipping tax. It applies to a sale within 730 days. The Province exempts building activity: demolishing a housing unit and building new ones, or adding a unit to a property that has one. The work must follow local bylaws and the Building Code. A return may still be filed, so confirm the exemption against your facts.
- GST. New units carry 5% GST. A first-time buyer who will live in the unit gets the full 5% back on a new home up to $1,000,000, falling to nothing at $1,500,000. See GST rebates on a new home.
Three lots, three answers
A 6,500 sq ft lot in the Township. That is about 604 m² (6,500 sq ft), over the 280 m² (3,014 sq ft) line and under 4,050 m² (43,594 sq ft). If it is serviced, inside the boundary and in a restricted zone, the Township permits 4 units. A stratified resale is the exit.
An 8,000 sq ft lot in Surrey. That is about 743 m² (8,000 sq ft). Six units need a qualifying bus stop within 400 m. A future station confers nothing. Once a SkyTrain station opens, the lots around it become a Transit-Oriented Area, which sits outside the small-scale rules. Check the stop before you price a sixth door.
A 6,500 sq ft Fort Langley parcel with a 1912 home. Heritage character does not exclude it. A designation under a heritage bylaw on the day the Act came into force does. Ask planning which applies, and check servicing and the Agricultural Land Reserve boundary.
Frequently asked questions
What is Bill 44 (2023) SSMUH?
Bill 44 is the Housing Statutes (Residential Development) Amendment Act, 2023. It received Royal Assent on November 30, 2023, and its main provisions came into force on December 7, 2023. SSMUH stands for small-scale multi-unit housing. In covered places, a lot zoned for detached houses or duplexes must permit 3 or 4 homes. A parcel of 280 m² (3,014 sq ft) or smaller gets 3. A larger parcel gets 4. Six are required on a lot over 280 m² within 400 metres of a qualifying bus stop. Zoning bylaws were due by June 30, 2024, unless the Province granted an extension. Source: Local Government Act, s. 481.3, and B.C. Reg. 262/2023 (bclaws.gov.bc.ca).The Act covers any parcel wholly or partly inside an urban containment boundary set by a regional growth strategy, whatever the municipality’s size. Elsewhere it covers parcels in a municipality with a population above 5,000. Township of Langley adopted its bylaw on November 18, 2024, after the deadline. Source: Local Government Act, s. 481.3 (4), and B.C. Reg. 262/2023, s. 2 (bclaws.gov.bc.ca).What did Bill 25 (2025) change?
It changed which lots the rules reach, not how many units they allow. The Housing and Municipal Affairs Statutes Amendment Act, 2025 received Royal Assent on November 27, 2025. Bill 44 counted a zone as restricted if it allowed only a house, a house plus one extra unit, a duplex, or a duplex plus extras. A zone allowing a house plus a suite plus a detached unit fell outside. Bill 25 brings those zones in. It also says a zone is restricted across all its lots if any parcel in it is limited to a detached house or duplex. Bylaws were due by June 30, 2026, unless the Province granted an extension. Source: Bill 25, 2025, section amending Local Government Act s. 481.3 (bclaws.gov.bc.ca).Are there lots the rules simply do not reach?
Yes. The Act excludes land outside the urban containment boundary, land not connected to municipal water and sewer, parcels over 4,050 m² (43,594 sq ft), and land in a zone with a 4,050 m² minimum lot size. It also excludes land under the Heritage Conservation Act, and land designated under a heritage bylaw on the day the Act came into force. Land in a transit-oriented area and hazard land with a professional’s report are excluded too. Source: Local Government Act, s. 481.4, and B.C. Reg. 262/2023, s. 3 (bclaws.gov.bc.ca).The Agricultural Land Reserve (ALR) is not on the Act’s list. The Agricultural Land Commission Act overrides any bylaw that permits more than it allows. Reserve land zoned single-family must still permit a secondary suite or accessory dwelling unit. On a parcel of 40 hectares or less, an additional residence can be up to 90 m² (969 sq ft) if the principal residence is 500 m² or less. Above 40 hectares it can be up to 186 m² (2,002 sq ft). Source: Agricultural Land Commission, Additional residential structures in the ALR guidelines (alc.gov.bc.ca), and the Province’s policy manual.How many units can I build on a single-family lot?
The Province sets a minimum of 3 or 4 units, depending on lot size. A parcel of 280 m² (3,014 sq ft) or smaller carries 3. A larger parcel carries 4. A lot of exactly 280 m² (3,014 sq ft) gets 3. Six units are required on a parcel of at least 281 m² (3,025 sq ft) within 400 metres of a qualifying bus stop. A stop qualifies if a route has a bus at least every 15 minutes on average, 7 a.m. to 7 p.m. Monday to Friday and 10 a.m. to 6 p.m. Saturday and Sunday. These are minimums a bylaw must permit. Siting, height, setbacks and lot coverage come from the local bylaw. Source: B.C. Reg. 262/2023, s. 2 (bclaws.gov.bc.ca).The Province’s policy manual says municipalities should work with the transit operator to identify qualifying stops. It says the lowest level of service may be used where service varies seasonally. The regulation itself does not mention seasons. Abbotsford has no qualifying stop on the measurement this site made of BC Transit’s schedule data in September 2026. Township of Langley’s published guidance lists 3 or 4 units and no six-unit tier. Whether a bylaw without that tier meets the Act is a legal question for the Township. Source: Provincial policy manual, and Township of Langley, Small-Scale, Multi-Unit Housing (tol.ca).Did public hearings get abolished?
For two kinds of zoning bylaw, yes. A council must not hold a hearing on a bylaw whose sole purpose is to comply with s. 481.3. It also must not hold one when an Official Community Plan (OCP) is in effect, the bylaw is consistent with it, the sole purpose is residential development, and housing is at least half of the floor area. A rezoning that needs an OCP amendment still gets a hearing. Source: Local Government Act, s. 464 (3) and (4), as added by Bill 44 (bclaws.gov.bc.ca).Has Township of Langley adopted a SSMUH bylaw?
Yes. Township of Langley adopted its zoning amendments on November 18, 2024. Eligible lots get 3 units at 280 m² (3,014 sq ft) or smaller, and 4 units up to 4,050 m² (one acre). Lots outside the criteria get one home plus a secondary suite or accessory dwelling unit. On April 27, 2026, council adopted Schedule 4 of the Official Community Plan, a development permit area for small-scale housing. A permit is required unless an exemption applies. Check the Township’s current bylaw and zoning map for a specific lot. Source: Township of Langley, Small-Scale, Multi-Unit Housing (tol.ca).Can I subdivide and sell each unit separately?
Often, by stratifying the building under the Strata Property Act. Whether it works depends on the form: detached homes, attached townhouse-style units, or a house with a suite and a coach house. Splitting into separate fee-simple lots is a full subdivision application. Talk to your municipality’s planning department and a real estate lawyer before you design. Source: Strata Property Act, Part 2 (bclaws.gov.bc.ca).How does SSMUH interact with the Foreign Buyer Ban?
Zoning does not decide it. The federal Prohibition on the Purchase of Residential Property by Non-Canadians Act applies to a property based on its own definitions, not on the density its zone permits. The Act is set to end on January 1, 2027 unless the government extends it; the federal budget of November 5, 2026 proposes extending it to January 1, 2029 for existing homes, with new homes exempt, and that is not law yet. Check both the definition and the end date before structuring a purchase. Source: Department of Finance Canada, news release extending the prohibition to January 1, 2027 (canada.ca).How does SSMUH affect property values?
The law does not set a price. It sets a minimum number of homes a bylaw must permit, and the value of that right depends on what you can build and sell. That turns on construction cost, the bylaw’s siting and parking rules, and what finished units sell for nearby. A lot’s permitted unit count is a fact you can check. The price premium is a forecast. Source: Local Government Act, s. 481.3, which sets minimum permissions and nothing about price (bclaws.gov.bc.ca).What about Short-Term Rentals on SSMUH units?
Short-term rentals are limited to principal residences in many B.C. communities. A unit that is not the operator’s principal residence may not be eligible. Check the Province’s short-term rental rules and your municipality before counting any short-term income. Source: Government of British Columbia, Short-term rentals (gov.bc.ca).
