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. North York sees 133 cm of snow and -4.2°C winter averages.
An investment ADU is underwritten before it is designed: the build cost, the $8,000-$14,000 under the City of Toronto fee schedule in approvals and the achievable North York rent decide the unit size, not the other way round. We price the feasibility stage as a standalone deliverable so the numbers can be tested against your North York parcel before any commitment to design. A legal second unit changes the appraisal basis of the property, which is the return most owners underestimate next to the monthly rent.

A legal, permitted second unit changes how the property is appraised in North York - it is valued partly on income rather than purely on comparables. An unpermitted suite does the opposite: it is discounted or excluded entirely, and it surfaces on every purchaser's title and insurance review.
