Uxbridge calls itself the Trail Capital of Canada, and the moraine kettle-and-kame topography that makes those trails also makes the building sites: sharply rolling ground where a level 700 sq ft ADU pad often needs a retaining wall. We budget site grading as a distinct line here, not as a rounding error. Uxbridge permits additional dwelling units; the Oak Ridges Moraine covers most of the township and the historic downtown carries heritage designations.
Moraine acreage on private servicing surrounding a compact serviced village with Victorian-era lots.
A laneway house is only buildable where the rear lane is a registered public right-of-way with the clear width the fire route table demands, so the first thing we measure in Uxbridge is the lane itself - width, surface, and the unobstructed path from the lane edge to the proposed front door. Servicing runs from the main house, not the lane: water, sanitary and the electrical feed are trenched across the rear yard, which is why the excavation has to land inside the May-October window rather than after it. Two storeys over a 1.2 m frost footing is the usual envelope, with the second floor set back from the lane face to hold the angular-plane limit.

Yes - a laneway suite requires frontage on a public lane that meets the emergency-access width, and we confirm that from the municipal lane register before any design work. If your Uxbridge lot has no qualifying lane, the same rear-yard area usually supports a detached garden suite instead, which is reviewed under the same uxbridge permits additional dwelling units; the oak ridges moraine covers most of the township and the historic downtown carries heritage designations pathway.
