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.
