Etobicoke ADU Permit Process - City Bylaws
In Etobicoke, Ontario homeowners who want to add an accessory dwelling unit (ADU) — a basement apartment, garden suite or secondary unit — must follow City of Toronto building, zoning and safety rules. This guide explains the typical permit process, which departments enforce the rules, common compliance issues, and practical action steps to apply, inspect and legalize an ADU. Requirements vary by property, and some projects may need a zoning review or Committee of Adjustment application before a building permit can be issued.
Overview of the Permit Process
The ADU process generally includes site and zoning review, preparing construction drawings, submitting a building permit application, paying applicable fees, and passing inspections before occupancy. Depending on lot size, parking and other zoning rules, you may need a variance or approval before applying for a building permit.
- Prepare plans and drawings to meet the Ontario Building Code and Toronto zoning rules.
- Confirm property zoning and permitted unit types with the city planning pages.
- Apply for a building permit with Toronto Building; include HVAC, plumbing and electrical plans.
- Allow time for review and possible requests for revisions from reviewers.
Penalties & Enforcement
Enforcement for unpermitted ADUs in Etobicoke is carried out by Toronto municipal departments. Municipal Licensing and Standards (MLS) and Toronto Building can issue orders to stop work, require compliance or initiate prosecutions where a structure does not meet building or property standards. Administrative fines, court prosecution, and stop-work orders are possible remedies; specific fine amounts for ADU-related violations are not specified on the cited page.
Inspections and complaints are handled via the city's building services and bylaws. For inspections, permit status, or to report an unsafe or unpermitted unit contact Toronto Building through the city apply-for-a-building-permit page Toronto Building - Apply for a Building Permit[1].

Appeals and reviews vary by decision type: zoning decisions, Committee of Adjustment rulings and some planning approvals have appeal routes to the Ontario Land Tribunal; building permit refusals have administrative and judicial review options. Exact time limits for appeals are stated on decision notices and relevant statutes; check the decision or contact the issuing office for deadlines.
