What is a secondary suite?
A secondary suite is an approved dwelling unit (with its own kitchen and living area as well as separate external access) within a larger one-family or two-family dwelling.
Secondary suites may share internal access with the main dwelling unit.
Review the steps to creating or legalizing a secondary suite before submitting an application.
Add a new secondary suite to your home or legalize a secondary suite that was created without permits.

Removing your secondary suite?
If you no longer want a secondary suite in your home, you will need to apply for the appropriate permit(s) before you:
- Remove the kitchen/cooking facilities (for example, the range, etc)
- Resolve any other work that was previously completed without a permit
Contact the Services Centre for further information about the permit application process.
Buying a home with a secondary suite?
Did you know that you when you purchase a property, you are responsible for any work completed without a permit even if the work was competed by a former owner or before you lived there? This includes secondary suites.
Request an approved use letter to find out if the secondary suite in your home is permitted.
Important note Our Zoning and Development By-law only allows one secondary suite per single family home.
