Feasibility Check
Does your lot qualify?
Start with your address — we'll check your city's zoning map instantly. No email required to see your result.
What's the property address?
We query the City of Toronto and Mississauga zoning maps directly. Takes about two seconds.
What this check actually tells you
Type an address and we read the zone code straight off the municipal map. That answers one question: whether the zoning on your lot permits a detached additional residential unit at all. It is a first screen, not an approval.
What it can determine
- The zone code the municipality has assigned to your property
- Whether that zone permits a garden or laneway suite in principle
- Which municipal rule set applies to your lot
What it cannot determine
- Whether your rear yard is deep enough once setbacks and separation are applied
- Whether a fire access path of the required width and height physically fits
- Whether protected trees, easements, grade or servicing distance rule the build out
- Whether your lot abuts a public lane, which decides garden suite versus laneway suite
Those four are the reasons most lots that look fine on a map do not proceed. They need a survey and a site visit, not a lookup.
Municipalities currently supported
Instant zone lookup covers Toronto and Mississauga. For Brampton, Oakville, Milton, Burlington and the rest of the GTA there is no instant zone code — we check those manually.
What happens if the lot looks feasible
We ask the lot questions the map cannot answer. If it still holds, we book a free site assessment and measure the things that actually decide the project. No obligation, and no cost.
This tool does not grant, guarantee or predict municipal approval. Zoning permission is the first of several tests, and the municipality is the only authority that can approve a suite.
