What makes a Whitby suite legal, and what only makes it rentable
Whitby, like Ajax and Oshawa, requires an additional dwelling unit to go on the municipal register, and that registration follows building, electrical and fire inspections rather than a form. Provincial rules reportedly allow up to three units on most urban residential lots now, but permission to build differs from a unit that has passed inspection. When a listing says apartment or in-law suite, ask the listing side for its registration number and permit history; if neither exists, price the work of adding fire separation between floors, interconnected smoke alarms, a bedroom window big enough to climb out of, and ceiling height that meets the code. Parking matters in Whitby too, since the Town expects a space for the second unit and some 1960s driveways in Blue Grass Meadows hold two cars at most. The same questions apply across the town line, so use them in Oshawa and Ajax as well, then let the Millers compare what each suite could reasonably bring in.
