- Zoning is set by the local government's zoning bylaw, so the answer for your lot comes from the municipality or regional district where it sits.
- Since the June 30, 2026 deadline, many single-family zones must allow extra units, but exemptions and late adopters mean you should check the current bylaw for your own lot.
- Zoning is only one layer: development permit areas, building permits and, in some places, Agricultural Land Reserve rules can also affect what you can do.
Before you buy a property, plan a suite, or think about building something new, you need to know what the zoning allows. A listing or a neighbour's comment is not a reliable answer. The rules that count are in the bylaw that applies to that exact parcel.
In British Columbia, zoning has also been changing. Provincial rules now require many local governments to allow more housing on lots that used to be limited to one house. This article explains where to look, how to read what you find, and what to double-check.
This article covers the law of British Columbia.
Start with the local government that covers the lot
Zoning is set through a zoning bylaw adopted by a municipality or regional district. How you find the right zone for a lot therefore depends on the local government, so that is the place to start. You first need to know which local government covers the property: a city, a district municipality, or a regional district electoral area.
The local government's planning or development services department is the natural place to confirm the zone for a specific address. Ask them to confirm it in writing if you are relying on it for a purchase.
- Find the property's civic address and legal description.
- Identify the municipality or regional district that covers it.
- Look for the zoning map or online mapping tool on that local government's website.
- Note the zone name or code (for example, a code for a single-family residential zone), then open the bylaw text for that zone.
How to read the zone in the bylaw
Each zone in the bylaw has its own section. It normally lists permitted uses, and then rules such as lot coverage, building height, setbacks from property lines and parking. Read the permitted uses first, then the conditions. Check the definitions section as well, because words like "secondary suite" or "accessory dwelling" have specific meanings.
Provincial law also places a limit on how local governments use their powers. Development permit area designations and land use regulation powers must not be exercised in a way that unreasonably prohibits or restricts the use or density of use required by section 481.3 of the Local Government Act, the provincial housing rules. If a bylaw looks stricter than the provincial minimums, that is worth raising with a lawyer or the local planning department.
- Permitted uses in the zone
- Maximum number of units or dwellings
- Setbacks, height and lot coverage
- Parking requirements
- Any special conditions or overlays noted in the bylaw
Small-scale multi-unit housing: what may now be allowed
The Province requires zoning bylaws to permit more housing in zones that used to allow only single detached homes. In a restricted zone, the bylaw must permit at least one additional unit inside the dwelling, such as a basement suite, and/or at least one additional unit in another building on the parcel, such as a laneway or garden suite. Secondary suites and detached accessory dwelling units are allowed province-wide in single-family residential zones where three- to six-unit zoning is not required.
| Situation | Minimum the bylaw must allow |
|---|---|
| Single-family or duplex parcel 280 m² or smaller, inside an urban containment boundary or in a municipality over 5,000 people | At least 3 units |
| Same type of parcel larger than 280 m² | At least 4 units |
| Parcel larger than 280 m² near a frequent transit bus stop, in a municipality or regional district of at least 5,000 people | Up to 6 units |
A frequent transit bus stop means a route with 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. on Saturday and Sunday. The required use and density apply only where residential use is permitted on the parcel.
Exceptions and timing: why you still need to check
Local governments had to update their bylaws by June 30, 2026 unless they applied for an extension. That date has passed, but some places had extensions or are still adopting bylaws, so the bylaw you read may not yet reflect the new rules. Confirm the current version with the local government.
Several exemptions can also apply. The 3 to 4 unit rule does not apply where the zone already allows three or more dwelling units on the parcel. The minimum unit counts do not apply to land that is not connected to a municipal or regional district water or sewer system, to parcels larger than 4,050 m² or zones with a 4,050 m² minimum subdivision lot size, or to certain heritage-protected land. A local government relying on one of these exemptions must give the minister written notice identifying the land and the exemption.
Siting, size and form standards can also be set by provincial regulation, and local governments must consider provincial guidelines. Specific limits on height, parking or setbacks vary by local government, so read the actual bylaw.
What else can affect the lot, and what to do next
Zoning is not the whole picture. In a designated development permit area, land generally cannot be subdivided and construction cannot start until a development permit is issued, unless an exemption applies. Those areas can be designated for reasons such as protecting the natural environment or protecting development from hazardous conditions. Land in the Agricultural Land Reserve has its own rules on subdivision and housing.
- Confirm the lot's legal description and the local government that covers it.
- Find the zone on the official zoning map and read the current bylaw text.
- Ask whether the lot is in a development permit area or the Agricultural Land Reserve.
- Ask the planning department whether the bylaw has been updated for the provincial housing rules.
- Get answers in writing before you rely on them for a purchase or build.
- Speak with a lawyer if the zoning affects a purchase condition or you think the bylaw is out of line.
Frequently asked questions
Can I find a property's zoning from its title search?
The zoning for a lot comes from the zoning bylaw adopted by the municipality or regional district that covers it. Contact that local government to confirm which zone applies. How a title search fits into your situation depends on the facts, so it is worth confirming with a lawyer.
Does my single-family lot now allow a basement or laneway suite?
It may. Secondary suites and detached accessory dwelling units are allowed province-wide in single-family residential zones, in all municipalities and regional district electoral areas, where three- to six-unit zoning is not required. Local conditions on siting and size vary, so check your bylaw.
Do the three, four and six unit rules apply to every lot?
No. They do not apply to some lots, such as land without municipal or regional water or sewer service, parcels over 4,050 m², or certain heritage-protected land. The 3 to 4 unit rule also does not apply where the zone already allows three or more dwelling units.
Is the zone the same as a development permit requirement?
No. A development permit is a separate approval needed in a designated development permit area before construction or subdivision, unless an exemption applies. Ask the local government whether your lot is in one.
