Your deck may or may not need a building permit. The zoning by-law outlines the specific regulations for deck locations.
Distance from property line: Decks may encroach up to 3 metres (9-10 feet) into the required yard setbacks, but must always remain at least 1.2 metres (3 -11 feet) from your property line. If you live beside an Open Space zone (OS4 or OS5), you must increase that to a 3 metres (9 -10 feet) setback. It's always best to verify the zoning around your house prior to planning your deck, to avoid costly errors. This can be done by calling 519-930-3510.
New subdivisions: Make sure you do not affect or alter the way water flows across your property. Do not start construction until after the subdivision is assumed. Property lines, grading and other alterations may change, which can the height and location of your deck.
Balconies, porches and enclosed decks: If the words balcony, porch, or enclosed deck (walls around your deck) better define your project, there are other regulations that may affect your design. Contact a Municipal Law Enforcement Officer prior to planning your construction to discuss the correct definition for your project and ensure the right regulations apply. Call the zoning office at 519-930-3510.
The zoning by-law regulates requirements for all accessory structures such as sheds and detached garages.
The total lot coverage of all accessory buildings or structures on a lot cannot exceed 10% of the lot area in every residential zone. If you add up the floor area of all the accessory structures on your property, they cannot cover more than 10% of your lot. You need to know your lot dimensions, the "footprint" of your house, the dimensions of all existing and proposed accessory structures, and the coverage that your zone permits when determining the size of a new accessory structure.
The height of an accessory structure is measured from the average finished grade (ground) to the upper-most point of the building structure, and shall not exceed 4 metres (13.1 feet).
You can increase the height up to 6 metres (19.7 feet) as long as you increase the distance from the property line by the same amount that you increase the height. For example, if you want to build 1.5 metres taller (than the permitted 4 metres), then you need to move the building 1.5 metres farther from the property line than the minimum.
Minimum setbacks and building location
Accessory buildings and structures are only permitted in the interior side yard or rear yard, not the front or exterior side yards.
They can be no closer than 0.6 metres (2 feet) to the side or rear lot lines.
If the height exceeds 4 metres (13.1 feet) the setback from the side and rear lot lines must be increased by the difference in the height above 4 metres (13.1 feet), to a maximum of 6 metres (19.7 feet).
Note: Sheds and other accessory structures less than 10 square metres (108 square feet) are exempt from the setback requirements. However, no part of the accessory structure can overhang the property line and the structure must be entirely in the rear yard.
Along with sheds, detached garages, shops, cabanas, pool houses, and "without limiting the generality of the foregoing, a heat pump, air exchanger, air conditioner or a swimming pool - either above or below ground - are structures" according to the by-law.
As many as you want, provided that you don't cover more than 10% of your lot with accessory structures, nor exceed the overall coverage as described by your zone.
