Toronto’s garden-suite fire-access guidance sets a route between the public street and the proposed suite. The required route depends on the suite’s sprinkler status and other design details. These published criteria are specific to Toronto garden suites; they do not establish compliance for a particular lot or apply automatically to a laneway suite or another municipality.

Published route criteria

The City of Toronto’s current guidance describes these minimum unobstructed path dimensions:

Garden-suite condition Minimum path width Minimum clear height
Sprinklered 0.9 m 2.1 m
Non-sprinklered 1.0 m 2.1 m

The city says the ordinary path may be up to 45 m from the public street to the garden-suite entrance. A route up to 90 m may be considered with an additional fire-safety measure acceptable to the city. The guidance also describes a hydrant-distance check tied to where a firefighting vehicle would park. Confirm the measurement points, route, applicable code, and acceptable measures with Toronto Building and Toronto Fire for the actual design.

If the required width cannot fit on the owner’s property, Toronto describes a Limiting Distance Agreement as a possible way to establish shared fire access over a neighbouring property. The agreement has a city template and title-registration process. It does not grant general access to tenants, and signing one does not guarantee a building permit; the project must still comply with zoning, the Building Code, and other applicable law.

Prepare the property-specific check

Have a qualified designer measure and show the route on an accurate site plan, including property lines, buildings, obstructions, route width and height, hydrant and vehicle locations, and any proposed shared area. Confirm whether the design is sprinklered, which distance pathway is proposed, and what supporting fire-safety measures the city will accept. If access crosses another property, obtain legal advice and confirm the city’s current agreement and registration requirements.

Do not use these figures to self-certify a route or design fire-safety systems. The city’s guidance is a review path, not a site approval. For broader route and authority questions, see ADU lanes, alleys, driveways, and fire access.
