Toronto Garden Suite Zoning, Permits & Feasibility Analysis
A garden suite is a detached residential unit in the rear yard of a property that does not rely on laneway frontage.
Eligibility depends on rear yard depth, separation from the main house, firefighter access, soft landscaping, and angular plane controls.
Check this against your actual Toronto property.
