Short answer: Etobicoke follows the City of Toronto's garden suite rules. Most lots are under Zoning By-law 569-2013, s. 150.7: up to 120 m² (60 m² for one storey), 4.0 m or 6.3 m high depending on distance from the house, and a building permit is always required. Two Etobicoke-specific checks come first: whether your lot is still under a former municipal by-law, and whether ravine, tree or TRCA rules apply. For the full Toronto process, read the Toronto laneway and garden suite permit guide.

Which by-law applies in Etobicoke
The former City of Etobicoke had its own zoning by-law before amalgamation in 1998. Zoning By-law 569-2013 harmonized most of those rules, and it is the by-law for most Etobicoke lots. The City says a property shown in grey on its interactive map is still subject to a former municipal zoning by-law. Check your address first; if it is grey, Toronto Building Customer Service can confirm which rules apply, and the 569-2013 garden suite figures below may not.
Garden suite rules under By-law 569-2013
- Size: 120 m² of gross floor area at most, or 60 m² if one storey (s. 150.7).
- Height: 4.0 m when the suite is less than 7.5 m from the house; 6.3 m when it is 7.5 m or more away.
- Separation: under By-law 849-2025, at least 4.0 m from the main wall of the house if the suite is no taller than 4.0 m, and at least 7.5 m if it is taller. (A 5.0 m east-end exception in the by-law does not cover Etobicoke.)
- Rear setback: on lots deeper than 45.0 m, the greater of 1.5 m or half the suite's height; otherwise 1.5 m. Add 1.5 m where rear-wall windows sit above 4.0 m.
The Toronto guide covers fire access, the Made-in-Toronto pre-approved plans, fees and the full permit process. We do not repeat them here: see Toronto laneway and garden suite permits.
Etobicoke local checks
- Ravines and trees: on lots near a ravine or creek valley, Toronto says a permit is required to injure or remove a by-law-protected tree, ravine or natural feature, and the tree by-law changes that took effect September 1, 2026 strengthen protections (City of Toronto).
- TRCA: if the lot is in a Toronto and Region Conservation Authority regulated area, you need a TRCA permit as well. TRCA has a regulated area search.
- Minor variances: designs that miss a zoning standard go to the Committee of Adjustment before the building permit.
Permit steps
- Check the lot. Confirm the by-law (569-2013 or former municipal), the survey, ravine and TRCA status, trees, servicing and fire access. Start with our free feasibility check.
- Resolve variances or permits first. Committee of Adjustment, tree or ravine permits, and TRCA permits come before or alongside the building permit.
- Apply for the building permit with the City of Toronto, then build and inspect through occupancy.
