If you plan to build a new structure, add an addition, or alter an existing building in Ottawa, you’ll need a building permit if the area is over 10 square metres (about 108 square feet). Examples of additions that require a permit include sunrooms, solariums, attached garages, porches, and one or two-story additions.
The Ontario Building Code sets out the minimum requirements for elements like framing and foundation. You can access the code on the Ontario Ministry of Municipal Affairs and Housing website.
