Barrie’s Building an Addition quick-start guide states that all additions require a building permit.
The City directs applicants to confirm compliance with the Zoning By-law, conservation authority requirements and other applicable law where they apply.
For properties on a private septic system, Barrie says the existing system must be reviewed by a qualified designer for Ontario Building Code compliance.
Barrie directs applicants to use APLI and provides building forms, checklists and electronic document standards in its services portal.
