Making changes to your home

An accessory permit is required when making changes to your home such as installing, constructing or renovating building components, HVAC systems, electrical, plumbing and gas equipment when it's separate from the original building construction.


Examples of the type of work that would require an accessory permit and inspection include:

*Please note: The permit list above is not all inclusive. If you are planning to work on your property, adding to or altering any system on a property, please contact Building Inspections to find out if a permit is required.

Apply for an accessory permit

Your permit application will be submitted to and reviewed by our Building Inspections department.

  • Starting January 2026, a fee of $100 will be applied to each homeowner-led trade permit (electrical, plumbing, and gas). This fee supports the resources needed to keep your project progressing smoothly, and aligns with fees in neighbouring municipalities and industry standards. For a full list of permit costs, please refer to the User Fees Bylaw (pdf). Hired contractors are exempt from this fee.
