Before you start

What to know.

Where they are allowed
Toronto permits laneway suites and garden suites on most residential lots that meet its rules. Ontario also allows additional residential units province-wide, but each municipality sets its own standards, so we check yours.
Emergency access
Firefighters must be able to reach the suite from the street within a set distance and along a clear path. This is the requirement that most often decides whether a lot works.
Servicing
The suite normally takes its water, sewer and power from the main house, which can mean trenching across the yard.
