Garden suites are an innovative solution for homeowners in Toronto and the Greater Toronto Area (GTA) who want to add value to their properties, create additional living spaces, or provide accommodations for family members or tenants. However, constructing a garden suite requires specific permits to ensure compliance with zoning by-laws and the Ontario Building Code (OBC).
To build a garden suite, homeowners must apply for a building permit. This process involves meeting key requirements, such as adhering to zoning regulations, emergency access routes, and tree protection laws. Some of the critical considerations include:
Garden suites have different zoning and access rules than laneway suites. If your property abuts a public laneway, the project may need to be reviewed under laneway suite rules instead. Source: City of Toronto garden suites
