Definition of Accessory suite

Secondary Suite is an urban planning term for an additional separate dwelling unit on a property that would normally accommodate only one dwelling unit. A secondary suite is considered "secondary" or "accessory" to the primary residence on the parcel. It normally has its own entrance, kitchen, bathroom and living area. Such a suite often is one of the following types:

• A suite above a rear detached garage,
• A suite above the main floor of a single-detached dwelling,
• A suite below the main floor of a single-detached dwelling (a "basement suite").
• A suite attached to a single-detached dwelling at grade, or
• A suite detached from the principal dwelling (a "garden suite" or "guesthouse").
