How to register a building investigation request

Make your investigation request by any of the methods listed below. Please have ready the address of subject property and your reason or concern.

After your inquiry is registered with our office, a building inspector is sent to investigate the situation.

Where a building inspector finds construction at the subject property in violation of the Building Code Act, they will issue the property owner with an Order to Comply.

The building inspector will contact the person who made the inquiry with the initial results of the investigation.
