The former City of York is dominated by mutual and shared driveways - two neighbours, one strip of asphalt. Resolving that easement is the first task on nearly every Weston or Silverthorn garden-suite project, because a shared drive changes both the construction access plan and the parking calculation the city reviews. City of Toronto laneway and garden suite by-laws apply; the York grid around Weston and Mount Dennis retains service lanes that qualify for laneway suites.
Older narrow semi-detached lots on a laneway grid, with frequent shared-driveway conditions that must be resolved before permit. York sees 124 cm of snow and -3.9°C winter averages. Ontario's 1.2 m frost-depth requirement governs every footing we pour for prefab and modular buyers, and the April-November season sets the excavation window.
Modular delivery in York is decided by the crane pick, not the drawings: the truck route, the overhead wires on your street and the setup radius determine whether a two-module unit is deliverable at all. We survey the pick before contract - overhead clearance, boom position, road closure requirements with City of Toronto - so the crane day is booked against a route that has already been proven. Where the pick fails, the same design is normally buildable stick-built on the identical 1.2 m foundation, so the feasibility work is never wasted.

Older narrow semi-detached lots on a laneway grid, with frequent shared-driveway conditions that must be resolved before permit. York scores 63/100 on walkability, so many tenants here do not need the extra parking space - that frees rear-yard area for the unit itself. We work regularly in Weston, Mount Dennis, Silverthorn.

Three things, in this order: overhead wires on the street, a side-yard or frontage too narrow for the crane setup radius, and a truck route that cannot legally carry the module. We check all three in York before contract, because a failed pick is the one problem no amount of design revision fixes on delivery day.
