Under the Building Code Act, a building permit is required for the construction of a new building, an addition, or alteration of any building or structure with a building area of over 10 square metres (approximately 108 square feet).
- Regardless of the deck’s walking surface area, if the deck is adjacent to or attached to the house and its walking surface is more than 600 mm (24 in.) above the adjacent grade, a permit is required.
- Regardless of the deck’s walking surface area, if the deck is an elevated deck providing principal access to a building a permit is required.
- If the deck is independent from the house (eg. is in the middle of the yard) and has a walking surface greater than 10 square metres (approximately 108 square feet) in area and its walking surface is more than 600 mm (24 in.) above the adjacent grade, a permit is required.
The Ontario Building Code outlines the minimum requirements for various elements, such as joist size, beam size, foundation requirements, guard requirements, and can be viewed on the Ontario Ministry of Municipal Affairs and Housing website.

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 sundeck, please refer to the following table.
