Etobicoke is really two build zones. South of the Gardiner in Mimico, New Toronto and Long Branch the original streetcar-suburb grid still has rear lanes, so laneway suites are permitted; north in The Kingsway and Markland Wood the lots are large and treed, which turns almost every project into a garden suite with an arborist report attached. Covered by the City of Toronto laneway and garden suite by-laws; the older Mimico and New Toronto grid does carry laneways, the Kingsway and Markland Wood do not.
Split personality - laneway-served lakeshore grid in Mimico and New Toronto, versus large treed lots in The Kingsway where garden suites dominate. Lake-moderated winters in Etobicoke - 115 cm of snow, -3.7°C average - give one of the longest build seasons in the region (April-November), which shortens the permit-to-occupancy timeline on adu building permit.
The permit is the whole project's critical path in Etobicoke: nothing is ordered and no crew is scheduled until the application clears, and approvals here run $8,000-$14,000 under the City of Toronto fee schedule. We prepare and submit the application, answer the plans-examination comments, and carry the file through zoning, building and - where the lot needs it - Committee of Adjustment, with City of Toronto as the reviewing authority. Approvals are quoted separately from construction on every contract we write, so a fee increase at City of Toronto is visible rather than buried in a build number.
