Building Inspections

Building inspections are required during construction to ensure all work is done according to the approved plans and the Ontario Building Code.

Required inspections must be completed prior to covering any work or proceeding to the next stage of construction. Failure to comply may result in the contractor/builder uncovering the work required for the inspection at his/her expense before proceeding with construction. If you wish to make changes to the construction authorized by your permit, consult the inspector assigned to your project.

Be sure to check the back of your yellow permit card for your required inspections. The approved permit plans must be kept at the construction site and made available to the inspector.
