The short answerConditional

A detached storage shed up to the Town’s published 15 m² exemption and without plumbing can be permit-exempt. Larger storage sheds require a permit.

East Gwillimbury separately lists a general 10 m² exemption for detached buildings, so the 15 m² threshold should be used specifically for a qualifying storage shed.

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.
