Garden Suites in North York - Design, Permits, Construction

North York's 1950s-60s bungalow belt around Willowdale and Don Mills gives us the deepest rear yards inside Toronto's boundary - 120 ft lots where a 700 sq ft garden suite still leaves usable green space. Almost none of these lots have a laneway, which is why nearly every North York project we build is a garden suite rather than a laneway house. Falls under the City of Toronto garden suite by-law; North York's post-war lots rarely have laneways, so garden suites (not laneway suites) are the usual permitted form.

A garden suite is a free-standing building in the rear yard, so the governing numbers on a North York lot are rear and side setbacks, the soft-landscaping percentage that has to survive, and the separation distance to the main house required for fire spread. Because it is new construction on undisturbed ground, the footings go to 1.2 m and the roof is engineered for 133 cm of annual snow load - both poured and framed inside the April-November season. Rear-yard access for the excavator is the practical gate: where deep post-war bungalow lots, commonly 50 ft × 120 ft, with rear yards large enough for a detached garden suite plus the required 1, we plan side-yard machine access or crane placement before pricing.
