Laneway Housing: Toronto’s next big buzzword.

While Toronto Real Estate is a hotly contested issue across the city, there’s no denying the existence of supply issues. With staggering immigration backlogs, slow construction, and continued roadblocks to development, the solution is clear: we need to build, and we need to build now.

Increasing affordable housing supply with condominiums is a noble effort undertaken by developers. The issue, however, is that developments move at a relatively glacial pace. Consolidation efforts are often tedious and under constant protest, development applications are disputed ad nauseam, and construction of towers can take years at a time.

City residents must get creative with housing supply. In addition to Legal Basement Apartments, city residents now have an additional way to provide affordable accommodation and earn passive income: Laneway Housing.

What is Laneway Housing?

A Laneway House is a detached secondary suite, constructed on an existing lot, with its main entrance facing a Public Laneway.

Toronto Laneway Housing Basic Requirements

There are four typical qualifying elements for Laneway Housing eligibility in Toronto:

  1. The subject property must have a minimum of 3.5 meters abutting a public laneway at the rear or side of the property. Public laneways must be city-recognized public laneways.
  2. There must be access from the front of the property to the laneway suite via a path being minimum 0.9 metres wide by 2.1 metres high. This can be obtained either on your own property or via an agreement with your neighbor.
  3. There must be a maximum distance of 45 metres between the public street and the laneway house, or, 90 metres distance from the street to the laneway house via public laneways (see sample sketch below). For fire safety, a hydrant must be located within 45 metres of the starting point of measurement.
  4. There must be no trees covered by Toronto’s Tree Protection within the proposed building envelope of the laneway suite.
