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.
ADU Design & Construction in Caledon
Every Caledon project we take on begins with two checks: the regulatory one - Caledon permits additional residential units, but most rural properties require a septic capacity assessment and, on the escarpment, Niagara Escarpment Commission approval. - and the physical one, because Rural acreages on private well and septic; Greenbelt and escarpment overlays cover a majority of the town's land area. We build across Bolton, Caledon East, Inglewood, Alton, Palgrave. Expect $9,000-$16,000 including Peel Region and septic permit charges in approvals cost on a typical Caledon lot, distinct from construction. The city's 76,581 residents and its employment base - Husky Injection Molding, Caledon Hills, Region of Peel among them - set the rental market a second unit enters, and the May-October season determines the realistic schedule from permit to occupancy.
