Coverage
Municipal rule
Shed
A shed follows the provincial 15 square metre exemption, but a detached garage or other accessory building needs a permit at 10 square metres (about 108 square feet) or more.
Deck
A deck or porch higher than 0.6 m (about 24 in) above grade needs a building permit in Kitchener. Lower decks do not.
Fence
Fences need no building permit; the fence bylaw sets height limits. Pool enclosures need a separate permit.
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.
