Coverage
Municipal rule
Shed
A detached one-storey shed up to 15 square metres, with no plumbing, needs no building permit in Vaughan. Larger, plumbed, or attached structures do.
Deck
An uncovered deck needs a permit once it is more than 0.6 m (about 23.6 in) above grade, or more than 18.6 square metres (about 200 square feet), or attached to the house. A small, low, freestanding deck does not.
Fence
Fences need no building permit; the fence bylaw caps height. Pool enclosures need a separate permit and inspection.
The provincial baseline
Under the Ontario Building Code, a detached one-storey storage shed of 15 square metres (about 160 square feet) or less, with no plumbing, does not need a building permit. Anything larger, with plumbing, or attached to another building does. Zoning rules (setbacks, height, lot coverage) always apply even when no building permit is needed.
