Ontario Building Departments Directory
Building permits in Ontario are issued at the local municipal level — each city, town, and township runs its own building department that reviews applications, issues permits, and conducts inspections. Upper-tier counties and regions do not issue permits directly.
Use the directory below to find the building department for your municipality: phone, office address, official website, and — where the municipality uses an online system (such as Cloudpermit or CityView) — a direct link to file a building permit.

More on permits and code
Questions people ask
Which building department do I apply to?
The municipality the property sits in, not the county or region in most of Ontario. In single-tier cities it is the city; in two-tier areas it is the lower-tier township or town. Septic permits sometimes go to a different authority, so ask.
Can I apply for a building permit online in Ontario?
Most municipalities now take applications through a portal, and many require it. A few smaller townships still want paper. The department’s website lists its method, fees and current review times.
How long does a building department have to review a house permit?
The Building Code sets a 10 business day target for a house once the application is complete. The clock starts when the application is complete, which is the part that usually takes longest.
Got a code question this page did not answer?
Ask it in plain English and the OBC Code Navigator answers with the Part, Section and Article from the Ontario Building Code, in about ten seconds. Two questions free. Your municipality and inspector still have the final word, as they always have.
