Are tiny homes legal in Ontario? What 327 municipalities allow

Illustrative photoYes, but it depends on the type of tiny home. Of the 327 Ontario municipalities whose zoning by-laws we read in October 2026 (home to 89% of Ontarians), 299 allow a backyard suite and 322 allow a small house on a foundation, while only 2 allow a tiny home on wheels as a home outright.
What did we find across Ontario?
Backyard suites and small houses on a foundation are allowed almost everywhere we looked. Tiny homes on wheels and bunkies are where the rules split.
| Build type | Researched | Allowed | With limits | Needs approval | Not allowed |
|---|---|---|---|---|---|
| Backyard suite | 307 | 158 (51%) | 141 (46%) | 4 (1%) | 3 (1%) |
| Tiny home on a foundation | 323 | 194 (60%) | 128 (40%) | 0 (0%) | 0 (0%) |
| Tiny home on wheels or park model | 326 | 2 (1%) | 187 (57%) | 20 (6%) | 111 (34%) |
| Bunkie or sleeping cabin | 317 | 32 (10%) | 78 (25%) | 1 (0%) | 178 (56%) |
"Allowed" means permitted with standard limits, and a building permit is the only approval. "With limits" means permitted only in some zones, or under a condition such as municipal services or a minimum house size. "Needs approval" means a minor variance, rezoning or temporary use by-law. Municipalities whose by-law doesn't address a build type are counted in the total but not in any column.
Can I live in a tiny home on wheels in Ontario?
Usually only in a mobile home park, a mobile home zone or on a temporary permission. 111 of the 326 municipalities we researched don't allow one as a home at all, and 187 allow it only in certain zones or parks.
The province adds two rules of its own. A unit on wheels that stays in one place, is connected to water, sewage or power, or is anchored can count as a building that needs a permit and must meet the Building Code (Ontario guidance). And a park model trailer built to CSA Z241 meets the Code only as a seasonal recreational building (2024 Building Code).
Our take: if you want to live full-time in a tiny home, plan for a foundation or a permitted mobile home site from the start. A home on wheels parked on rural land without a permit is the half-measure most likely to end with an order to move it.
Is there a minimum house size in Ontario?
Not from the province, but many towns set one. No Ontario statute sets a minimum floor area for a main house, and the Province's own guide says an open-concept tiny home can be as small as 17.5 m² (Ontario guidance). But 128 of the 323 municipalities we researched set a minimum above 37 m² (398 sq ft) in their main residential or rural zones. Here's what some of the larger ones require:
| Municipality | Answer | Minimum dwelling size |
|---|---|---|
| Whitby | Allowed with limits | By-law 2585 (single detached dwelling): R1 zones 111 m² for 1 storey, 74 m² for 1½ storeys or more; R2 zones 79 m² / 56 m²; other zones 67 m² / 56 m² [source] |

Can I build a garden suite or backyard suite anywhere in Ontario?
On most serviced urban lots, yes. Ontario's Planning Act stops municipalities from banning one residential unit in a building ancillary to a detached house, semi-detached house or rowhouse, on land inside a settlement area served by municipal water and sewers, as long as the lot has no more than three units in total (Planning Act s. 35.1). Towns can't set a minimum size for that unit or require more than one parking space for it (O. Reg. 299/19).
Rural lots on a well and septic aren't covered by that protection, so the local by-law decides. That's why 141 municipalities allow a backyard suite only with limits, often a minimum lot size or full municipal services. Our guide to ADUs in Canada covers sizes and costs.
Are bunkies allowed in Ontario?
Less often than people expect. 178 of the 317 municipalities we researched don't allow a detached sleeping cabin, and most of those that do cap its size and ban a kitchen. Our bunkie rules guide has the sizes for cottage country.
How did we research this?
We read each municipality's own zoning by-law, consolidated where one exists, along with its guide pages for additional units, in October 2026. Each answer on a municipality's page quotes the by-law and links to the section it comes from. We started with the largest municipalities and have covered 327 of Ontario's 414 so far; the rest need a current by-law from the municipality or a check by our team.
By-laws change and many have exceptions by zone, lot and servicing. Treat these numbers as where to start, and confirm with your municipality's planning department before you buy or build.
Questions people ask
- Are tiny homes legal in Ontario?
- Yes, on a foundation and as backyard suites almost everywhere we researched. Tiny homes on wheels are the exception: most municipalities allow them only in mobile home parks or zones, if at all. Check your town on our Ontario zoning page.
- What is the smallest house you can build in Ontario?
- The province sets no minimum for a main house, and its guidance says an open-concept tiny home can be as small as 17.5 m². Your municipality may set a larger minimum for its residential and rural zones; our Ontario zoning pages quote each town's figure.
- Can I put a tiny home in my backyard in Ontario?
- On a serviced urban lot, provincial law lets you add one unit in a building beside your house, so a tiny home on a foundation built as a garden suite is usually allowed. It needs a building permit and must meet your town's setbacks and height limits.
- Do I need a building permit for a tiny home in Ontario?
- Yes for a home on a foundation. A tiny home on wheels can also need one once it stays in one place, is hooked up to services or is anchored. Builders of homes 37 m² or smaller can use a two-permit process when the home is built in one town and installed in another.
- Where can I park a tiny home on wheels in Ontario?
- In a mobile home park, a park model resort or a land-lease community that accepts tiny homes, or on land zoned for mobile homes. Our places to park page lists Ontario parks that say they accept tiny homes, with whether they're seasonal or year-round.
