Check the zoning of an address

Before you buy a commercial unit or lease a storefront, check that the business is allowed on that land. Pick the city, enter the address, and we read the zoning from the city’s official zoning map data and explain it in plain words.

  1. Pick the city and type the address.
  2. Choose the matching address.
  3. Read the zone and the warnings, then confirm on the official map.

The address you type is sent directly to that city’s official server for the search. Korean Homes does not store it.

What the categories mean

Zone names differ by city, but grouped by use they fall into these groups. The grouping is to help you read the result; the zone’s list of permitted uses is what counts.

  • CommercialZones mainly for shops, restaurants and services. Each business type is still allowed or not by the zone’s list of permitted uses.
  • Mixed use (commercial + residential)Zones that allow commercial and residential uses together, such as shops at street level with homes above. Conditions can depend on the business and the floor.
  • OfficeZones mainly for offices. Some commercial or service uses may also be allowed.
  • Employment / industrialZones for jobs such as manufacturing, warehouses, logistics, auto service and some offices. Retail and restaurants are often limited or conditional.
  • ResidentialZones for homes. Shops and offices are usually not allowed, except very limited cases such as some home businesses.
  • InstitutionalZones for schools, hospitals, places of worship and similar institutions.
  • Open spaceParks, green space and natural areas. Commercial uses are rarely allowed.
  • Agricultural / ruralZones for farming and rural uses.
  • OtherUtilities, transportation, special planning areas and similar. Check the official map for details.

Why the map result is not the final word

  • A "commercial" zone does not allow every business. Restaurants, bars, auto repair, clinics, schools and others often have their own conditions.
  • Site-specific exceptions or special provisions change the permitted uses for that land.
  • With a holding (H) symbol, the listed uses cannot be used yet.
  • A business operating against today’s zoning may be a protected legal non-conforming use, but stopping or changing the use can lose that protection.
  • A business allowed by a temporary use by-law may have to stop when it expires (up to three years at a time).
  • Changing only the use (for example store → restaurant) can need zoning approval and a building permit even without construction.
  • City maps and data can lag behind recent amendments and Ontario Land Tribunal decisions.

The law behind it

What the official sources say 6
Planning Act — Power to pass zoning by-lawsPlanning Act, R.S.O. 1990, c. P.13, s. 34 (1), paras. 1 and 4
Zoning by-laws may be passed by the councils of local municipalities: … For prohibiting the use of land, for or except for such purposes as may be set out in the by-law within the municipality or within any defined area or areas … For regulating the type of construction and the height, bulk, location, size, floor area, spacing, character and use of buildings or structures to be erected or located within the municipality or within any defined area or areas …

In plain wordsA city council can use a zoning by-law to limit what land is used for and to regulate the type, height, bulk, location, size, floor area and spacing of buildings. So the same land allows different things depending on its zoning.

Planning Act — Holding provision (H)Planning Act, R.S.O. 1990, c. P.13, s. 36 (1)
The council of a local municipality may, in a by-law passed under section 34, by the use of the holding symbol “H” (or “h”) in conjunction with any use designation, specify the use to which lands, buildings or structures may be put at such time in the future as the holding symbol is removed by amendment to the by-law.

In plain wordsIf a zone code carries an H, the listed uses are allowed only in the future: council must amend the by-law to remove the H first.

Planning Act — Legal non-conforming usePlanning Act, R.S.O. 1990, c. P.13, s. 34 (9) (a)
to prevent the use of any land, building or structure for any purpose prohibited by the by-law if such land, building or structure was lawfully used for such purpose on the day of the passing of the by-law, so long as it continues to be used for that purpose

In plain wordsA use that was lawful before the by-law was passed is not stopped by it, as long as that use continues. A business operating against today’s zoning may be in this situation, but stopping or changing the use can lose the protection.

Planning Act — Temporary use by-lawPlanning Act, R.S.O. 1990, c. P.13, s. 39 (1), (2)
authorize the temporary use of land, buildings or structures for any purpose set out therein that is otherwise prohibited by the by-law. … which shall not exceed three years from the day of the passing of the by-law.

In plain wordsA city can allow an otherwise prohibited use for a limited time, no longer than three years at a time. A business running under a temporary use by-law may have to stop when it ends, so check the expiry date.

Planning Act — Minor variancePlanning Act, R.S.O. 1990, c. P.13, s. 45 (1)
may, despite any other Act, authorize such minor variance from the provisions of the by-law, in respect of the land, building or structure or the use thereof, as in its opinion is desirable for the appropriate development or use of the land, building or structure, if in the opinion of the committee the general intent and purpose of the by-law and of the official plan, if any, are maintained.

In plain wordsThe committee of adjustment can allow a minor variance from the by-law. It takes an application and a hearing, and it must keep the intent of the by-law and the official plan, so the result is not guaranteed.

Planning Act — By-laws must conform to the official planPlanning Act, R.S.O. 1990, c. P.13, s. 24 (1)
where an official plan is in effect, no public work shall be undertaken and, except as provided in subsections (2) and (4), no by-law shall be passed for any purpose that does not conform therewith.

In plain wordsWhere an official plan is in effect, a by-law that does not conform to it cannot be passed. So before hoping for a rezoning, check whether the official plan allows that use.
