Laneway suites in Toronto, made simple.

The rules, the approvals, and the smartest way to build a laneway home — handled end-to-end by one team.

Toronto Laneway Suite By-Laws & Approvals

In the summer of 2018, the City of Toronto officially amended its zoning by-laws to permit laneway housing as-of-right. Before this milestone, building a laneway suite required complex zoning amendments and expensive, time-consuming appeals. At Kasa Suites, we use these exact rules to take your project from drawings to keys without the friction.

The basics

What are laneway suites?

A laneway suite is a custom backyard home built on a lot that backs onto a public alley. At Kasa Suites, we design these premium detached units as a superior alternative to basement apartments — providing high-quality living space and excellent rental income without disrupting your main home.

Laneway suite dormers

Dormers & smart design

In Toronto, roof dormers are a smart way to maximize second-floor space. While they can extend beyond the required angular plane, their total width cannot exceed 30% of the suite’s front main wall (measured at 4.0m above grade). At Kasa Suites, we expertly design dormers that follow these exact rules — adding valuable headroom and natural light to your backyard home without zoning delays.
