Classify the structure before checking rules
The direct answer is that a Toronto home buyer should measure and identify every detached shed or accessory building, verify its permits and zoning status, compare its location with the survey, and inspect its structure, drainage and services before assigning value to it. A small storage shed, workshop, cabana and detached garage can follow different approval rules even when they look similar.
Record the exterior dimensions, approximate gross area, height, number of storeys, attachment to other structures, plumbing, electrical service and actual use. Ask when it was built or moved and request receipts, plans, permits, inspection records and warranties. Sam Kamra recommends describing the existing building precisely rather than relying on a listing label such as “studio” or “workshop.”
Separate permit exemption from zoning compliance
The City of Toronto says a shed can be exempt from a building permit when it is not more than 15 square metres in gross area, is one storey, is detached, is used only for storage accessory to the main building and has no plumbing. A shed of 15 square metres or more requires a permit. Other accessory structures larger than 10 square metres—such as workshops, detached garages, carports, pool houses or cabanas—can require permits, and attachment or plumbing can trigger a permit regardless of size.
Permit exemption does not mean unrestricted placement. Toronto's accessory-structure guide requires permit applications to show property lines, easements, setbacks, grade, lot coverage, parking, driveways and distances to other buildings. Zoning standards vary by property and may include exceptions from older municipal by-laws, so obtain a zoning review for the actual address instead of copying a neighbour's layout.
Compare the shed with survey and City records
Measure accessible setbacks to fences, lot lines, the house, lane and other buildings, then compare them with a current survey or site plan. Fences are not reliable proof of the legal boundary. Check for encroaching eaves, gutters, foundations, doors and roof overhangs, plus access needed for maintenance. The GTA survey and boundary checklist supports this review.
Ask Toronto Building for permits, approved plans, inspections and any open orders connected to the structure. Where the shed is permit-exempt, preserve evidence supporting the exemption, including measurements and intended storage use. Have the lawyer review title for easements, rights of way or restrictions that affect the area. Do not assume an unapproved building can be legalized or rebuilt in the same location later.
Inspect condition, utilities and drainage
Examine accessible roof covering, sheathing, framing, siding, doors, windows, floor, foundation or skids and connections. Note settlement, rot, corrosion, leaks, mould-like staining, pest entry, broken glazing and contact between wood and soil. Look at the condition in context: a freshly painted wall can conceal only appearance, not establish the integrity of framing or foundations.
Trace roof water and grading. Gutters, downspouts and hard surfaces should not create ponding at the house or discharge onto neighbouring property. If the structure has wiring, heating, fuel, plumbing or drainage, request the appropriate contractor and inspection records and ask the insurer whether the installation and intended use are acceptable. Sam Kamra's buyer guidance can help organize these questions, while additional GTA property resources support the wider ownership file.
Resolve use and repair plans before closing
Decide what the buyer actually intends to do there. Storage approval does not establish that a shed can lawfully become an office, sleeping room, rental unit, workshop with plumbing or accessory dwelling. Ask the City and qualified professionals about any conversion before paying for that future potential. Price removal, relocation, foundation, roof, drainage, electrical and landscaping work with written scopes, including access and disposal.
CB Herald's discussion of Sam Kamra and public LTB data illustrates evidence-based property review, while Barchart's report on the RealEstateBuyer.ca launch covers Sam Kamra's broader property-services work. The conclusion is practical: classify, measure, verify and inspect. Take unresolved issues to Toronto Building, the lawyer, insurer and qualified contractor before waiving conditions.
Questions and answers
Toronto Backyard Sheds FAQ
When does a Toronto shed need a building permit?
Toronto says a shed of 15 square metres or more requires a permit. A smaller shed is exempt only when it meets all stated conditions, including one storey, detached construction, storage-only use and no plumbing.
Does a permit-exempt shed still have to follow zoning?
Yes. Zoning rules can regulate location, setbacks, height, coverage and separation from buildings. The rules depend on the property and applicable zoning by-law.
Can a storage shed be used as a home office or sleeping space?
Do not assume so. The permit exemption applies to storage-only sheds meeting specific conditions. A different use or added services can require separate zoning, building and safety review.
What shed records should a buyer request?
Request plans, permits, inspection records, invoices, warranties, electrical or plumbing approvals, survey or site-plan evidence, and documents showing when and how the structure was built.
What physical shed problems should a buyer check?
Check for settlement, roof leaks, rot, corrosion, damaged framing, unsafe wiring, pest entry, soil contact, broken doors or glazing, ponding and drainage toward buildings or neighbouring property.
