Laneway houses in Oshawa

Oshawa is century houses around the downtown, 1920s and 1930s streets north of it, wartime and 1950s houses through the middle, and newer subdivisions north of Taunton. In Oshawa that means checking the lane, the fire access route and the lot depth against the rules before the design starts. A laneway house is a self-contained home at the back of a lot that fronts a public lane, built where the garage stood, and the lot check comes before anything is drawn.

Laneway houses · Oshawa

Oshawa, on the ground.

The Oshawa brief is usually a whole-home renovation of a century house, a second storey on a 1950s bungalow, or a lowered basement for a legal suite. The garage comes down, the services are trenched from the house or the street, and the new house goes up at the back of the lot with deliveries from the lane.

Permits in Oshawa

Paper first.

A laneway house needs a building permit with engineered drawings and a demolition permit for the garage, and the fire access route is part of the review. The City of Oshawa issues the permit, and heritage designation downtown adds a review to exterior work.

  • A building permit with engineered drawings is required, plus a demolition permit for the garage.
  • In Toronto, laneway suites are permitted as-of-right on qualifying lots under the City's by-law; a lot outside the rules goes to the Committee of Adjustment.
  • The fire access route from the street is part of the permit review.
  • Other municipalities have their own additional residential unit rules. [Kam confirms which ones Savino has built under.]

The paperwork wall: WSIB, insurance, licences, the HCRA status and the warranty, on one page and dated.
