Building Permits

The following information is designed to assist homeowners with building or home renovation projects. To ensure that your project aligns with all regulations, please review our Zoning By-law and the Ontario Building Code (OBC).

Before you apply

If your project does not comply with the Zoning By-law, you may be required to apply for a minor variance.
If your property is in an area subject to site plan control, you may have to submit an application for site plan approval.

Depending on the nature of your building project, you may need to consult one or more of these agencies to get approval before you apply:
