Frequently Asked Questions

What is a commercial change of use permit in Ontario?

A commercial change of use permit is required when a building or unit is proposed to be used for a different occupancy classification than it was originally approved for. Examples include converting a retail store into a restaurant, an office into a medical clinic, or a warehouse into commercial office space. The permit ensures the property complies with the Ontario Building Code and local zoning by-laws.

Do I need a change of use permit if I am not renovating the building?

Yes. A change of use permit may still be required even if no construction work is planned. The municipality must verify that the existing building meets the life safety, fire protection, accessibility, occupant load, and other Ontario Building Code requirements for the proposed new occupancy.

What is included in a commercial change of use permit application?

A complete change of use permit application typically includes a zoning review, Ontario Building Code data matrix, architectural permit drawings, existing and proposed floor plans, occupancy analysis, and any required structural or mechanical documentation. Our team prepares the complete application package, submits it to the municipality, and manages the review process through to permit approval.
