Garage Suite Conversion in North York

Only if the existing garage exceeds zoning performance standards (setbacks, height, lot coverage) under North York By-law 569-2013. About 70% of pre-1970 garages on narrow downtown lots require a minor variance; most post-1970 garages in North York, Scarborough, and Etobicoke meet as-of-right standards. We provide a written zoning review within 5 business days of receiving your survey.

A garage suite reuses an existing detached accessory structure (or its slab and footings); a garden suite is a purpose-built new dwelling. Garden suites have their own dedicated rules under By-law 89-2022 and the July 2025 amendments under By-law 849-2025, with different height and footprint allowances. Costs and timelines are similar, but if your existing garage is in good shape, the conversion path is faster and 15-25% cheaper.

Yes. Since Bill 23 (in effect since 2022) and North York's 2024-2025 By-law 569 amendments, up to four dwellings are permitted per lot as-of-right: main house, basement apartment, garage/garden suite, and one additional. The fourth unit typically requires Site Plan Control review. We routinely deliver three- and four-unit conversions on a single property.

Habitable rooms require 2.1 m (6'11") clear ceiling height per OBC 9.5.3, with 1.95 m (6'5") permitted under beams and bulkheads. Bathrooms, hallways, and storage have lower minimums. Older garage roofs with low collar ties often need to be raised, which is included in our Standard tier scope.

No. North York eliminated parking minimums for ARUs in 2022, harmonizing with Bill 23. You are not required to add or retain on-site parking for the garage suite. Two bicycle parking spaces are required (wall hooks or a simple rack).

North York Building Division targets 4 to 8 weeks for as-of-right ARU permits and 8 to 12 weeks for projects with a minor variance. We submit a complete package (architectural, structural, mechanical, electrical, OBC matrices) to maximize first-round approval and minimize back-and-forth.

A 1BR garage suite rents for $2,400 to $2,900/month in Leslieville, Roncesvalles, Bloor West, and Riverdale; $1,800 to $2,200 in North York and Scarborough; $1,750 to $1,950 in Mississauga and Brampton. Two-bedroom suites add 25 to 35% to the rent. Numbers reflect 2026 GTA market rents and assume the suite is registered, legal, and insured.

Yes — and this is critical. Once you have an occupancy permit, you must declare the ARU to your home insurer. Failing to disclose voids your policy at claim time. We provide the occupancy certificate and a one-page summary letter for your broker, who will re-rate the property as multi-unit residential (typically a $400 to $900/year premium increase).
