Local knowledge
Renovating in Toronto.
Housing
In Toronto, much of the housing is pre-war: narrow semis and detached brick houses with plaster walls, old wiring and shared party walls.
Permits
Building permits in Toronto are issued by the City of Toronto (Toronto Building). We prepare the drawings, submit the application and book the inspections.
Areas we cover
We work throughout Toronto, including Leaside, The Annex, High Park, Riverdale, The Beaches, Forest Hill and Lawrence Park.
Suites and multiplexes
Toronto permits laneway suites, garden suites and, on most residential lots, up to four units in a house. That makes basement apartments and rear additions more feasible here than in many suburbs.
Tight lots
Narrow lots and shared walls mean additions and underpinning often need a minor variance or a neighbour's cooperation, so the approvals take planning.
