Required inspections
At key stages of building construction, your work must be inspected to ensure that the completed construction complies with the Ontario Building Code. The permit plans and specifications must be on site and made available to the Building Inspector at the time of inspection. To ensure the availability of a Building Inspector, you should book inspections 48 hours in advance. Failure to have the appropriate inspection performed may result in your having to uncover and expose the work for inspection, or other Orders issued, etc.
The Building Inspector's name and phone number are identified on the building permit. For a list of required inspections that may apply based on the proposed finished basement, please refer to the table below.
