​Building a Secondary Dwelling

Building permits give legal permission to begin construction, subject to other required municipal approvals. Building permits ensure that the proposed construction will meet the minimum life and fire safety requirements contained within the Building Code.

Please refer to Building Services Announcements for up-to-date information about impacted services during the COVID-19 pandemic.

A secondary dwelling (sometimes referred to as garden suite) is a detached standalone dwelling unit which is in addition to the principal dwelling unit on the property. A secondary dwelling can only be one unit. It is often used as a rental property and must be registered with the City. This is different than a second suite contained within the principal dwelling. 

Pre-submission Inquiry

Prior to doing any planning on a potential secondary dwelling, it is advisable that you contact planneroftheday@barrie.ca to determine if a secondary dwelling is permitted on your property. These units are permitted on residentially zoned parcels that have municipal frontage and a primary unit on site. If permitted, you will be provided direction on how to proceed.
