Accessible and Barrier-Free Units in Caledon - Design, Permits, Construction

Most of Caledon sits inside the Greenbelt or on the Niagara Escarpment, and almost every rural property runs on private well and septic. An accessory dwelling unit here starts with a septic loading calculation - the existing bed often cannot legally take another bedroom, and a new tile field, not the building, becomes the largest single line in the budget. Caledon permits additional residential units, but most rural properties require a septic capacity assessment and, on the escarpment, Niagara Escarpment Commission approval.

Rural acreages on private well and septic; Greenbelt and escarpment overlays cover a majority of the town's land area.

Accessible design is dimensional before it is decorative: a barrier-free Caledon unit needs a level entry route from the driveway, 34-inch clear door openings, and turning circles that a standard 500 sq ft plan does not leave room for. We set the finished floor to grade at design stage, which changes the foundation detail on a 1.2 m footing and has to be resolved before the permit set is drawn, not after. 152 cm of annual snow makes the level entry a maintenance question too - we detail a covered, drained approach rather than a flush threshold that ices over.
