Laneway Homes 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.

Deep post-war bungalow lots, commonly 50 ft × 120 ft, with rear yards large enough for a detached garden suite plus the required 1.5 m separation.

A laneway house is only buildable where the rear lane is a registered public right-of-way with the clear width the fire route table demands, so the first thing we measure in North York is the lane itself - width, surface, and the unobstructed path from the lane edge to the proposed front door. Servicing runs from the main house, not the lane: water, sanitary and the electrical feed are trenched across the rear yard, which is why the excavation has to land inside the April-November window rather than after it. Two storeys over a 1.2 m frost footing is the usual envelope, with the second floor set back from the lane face to hold the angular-plane limit.
