GTA / Free address check

Check the address
before you spend.

Start with the address. BuildRules identifies the supported GTA municipality, then shows the relevant project rules and a free printable Project Brief. Toronto currently adds mapped zoning and property-level findings.

Start with the street number and name. Add the city or postal code for the fastest match.

GTA coverage & address data

Toronto includes mapped property zoning. Peel, Durham and Oakville use public municipal or regional address data; other current GTA cities can still route by municipality while exact civic-address validation is added.
