Oshawa runs a residential rental housing licensing by-law covering the wards around Ontario Tech and Durham College, so in Windfields and Northglen a new secondary suite needs a licence as well as a permit. Owners planning student tenancy get the licensing test folded into the design brief, because it sets bedroom count and parking. Oshawa permits additional dwelling units and operates a rental-housing licensing regime in the university district that a new suite must satisfy.
Older large-lot neighbourhoods near downtown, plus student-rental territory around Ontario Tech and Durham College where licensing applies. Oshawa sees 134 cm of snow and -4.1°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 Oshawa 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 Durham Region - 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 large-lot neighbourhoods near downtown, plus student-rental territory around Ontario Tech and Durham College where licensing applies. At 50/100 walkability, Oshawa suites usually keep one parking space: enough to clear the zoning review without surrendering the whole yard. We work regularly in O'Neill, McLaughlin, Northglen.

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 Oshawa before contract, because a failed pick is the one problem no amount of design revision fixes on delivery day.
