Building Permits & Inspections

Building permits ensure that construction within our municipality meets the standards set out in the Ontario Building Code.

The Building Division reviews all applications for building permits to ensure compliance with all applicable zoning by-laws and building code requirements.

For detailed information about the permit process and submission requirements, please see the following guides:

Mandatory Inspections

We perform inspections as mandated by the Building Code Act to ensure work complies with the approved plans and the Ontario Building Code.

By enforcing building codes, and assisting builders, designers and homebuilders, we ensure that the structures they create are safe not only for today, but for many years to come.

Construction may commence upon issuance of the Building Permit. Mandatory inspections are required to ensure that all work is done according to the approved plans including changes noted by the plans examiner.  Your building permit will include a list of the required inspections for your specific project.

Examples of construction stages when inspections are required:

  • "Prior to"
  • "Completion of"
  • "After fixtures installed"
  • "Final Inspection"
