What changes the answer
The City lists a storage-shed exemption with conditions on area, height, attachment, use and plumbing. Its permit-required list also includes structures 15 m² or greater. Confirm a shed at exactly 15 m² with Toronto Building before relying on an exemption.
Setbacks, lot coverage and location rules can apply separately from permit thresholds.
Toronto lists accessory structures such as detached garages, workshops, carports and pool houses larger than 10 m² as permit-required; attached structures or those with plumbing require a permit regardless of size.

Common questions
Can I put a shed right on the property line in Toronto?
Do not assume so. Setback and placement rules can apply even when the structure does not need a building permit.
Does a backyard office follow the same rules as a storage shed?
Not necessarily. Occupancy and intended use can materially change the applicable requirements.
