Coverage
Provincial baseline
Shed
Provincial baseline: a detached one-storey storage shed up to 15 square metres, with no plumbing, does not need a building permit in Ontario. Zoning setbacks, lot coverage, conservation authority rules, and any stricter Dysart et al rule still apply.
Deck
Provincial baseline: decks can need permits when attached, elevated, structurally complex, or serving an entrance. We have not verified Dysart et al's local deck page yet, so check the municipal building department before building.
Fence
Provincial baseline: ordinary fences are usually handled by local fence bylaws, not by a province-wide building permit rule. Pool enclosures, corner lots, heights, and sightlines can trigger separate Dysart et al rules.
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.
