The short answerConditional

A qualifying shed up to 15 m² can be permit-exempt when it is one storey, detached, storage-only and has no plumbing.

Every condition matters. If the shed is larger, attached, used for more than ancillary storage or contains plumbing, do not rely on the exemption.

Know the zoning terms

The shed may be permit-exempt. The property rules still matter.

Placement, setbacks and lot coverage may still apply even where a shed is exempt from a building permit.

Setback

A setback is the required distance between a building or structure and a property line, street, another feature or another regulated reference point.

Lot coverage

Lot coverage is a zoning measurement describing how much of a lot is occupied by buildings or structures under the applicable municipal rules.

Zoning by-law

A municipal rule set that controls how land and buildings may be used and developed, including matters such as permitted uses, setbacks, height, lot coverage and other site-specific standards.
