Garden Suites in Toronto
A garden suite is a detached home in the rear yard of a property. Here is what to know before you plan one.
WHAT IS A GARDEN SUITE?
A garden suite is a detached, self-contained dwelling unit in the rear yard of a residential property, separate from the main house. It is not on a laneway.
WHAT YOU NEED
• A building permit is required.
• Drawings and documents are required with the application.
• Zoning rules apply — for example size, height and setbacks — so check them first.
• Related plumbing and mechanical permits may apply, including for connecting water and sewer services.
CITY RESOURCES
Toronto provides garden suite application information and has published pre-approved garden and laneway suite resources to help owners start from designs that have already been reviewed.
PLANNING TIP
Talk to a designer and contractor early about servicing (water, sewer, electricity), access for construction and tree protection.
