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 Arran-Elderslie rule still apply.
Deck
Provincial baseline: decks can need permits when attached, elevated, structurally complex, or serving an entrance. We have not verified Arran-Elderslie'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 Arran-Elderslie 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.
