How Much Does a Shed Permit Cost in Toronto?

Most Toronto homeowners pay between $200 and $500 for a shed building permit, though this varies based on square footage and whether your project triggers zoning reviews. The City of Toronto calculates permit fees using the construction value and floor area, so a simple 100 square foot garden shed costs significantly less than a 200 square foot workshop with electrical. Before you budget, the more important question is whether you need a permit at all, since sheds under 10 square metres (about 108 square feet) are often exempt.

When Do You Actually Need a Shed Permit in Toronto?

The Ontario Building Code exempts certain small accessory structures from permit requirements, but Toronto's local bylaws add conditions that trip up many homeowners. Generally, you do not need a building permit if your shed is under 10 square metres in floor area, is one storey, has no plumbing or electrical, and meets all setback requirements from property lines.

However, you will need a permit regardless of size if your shed includes electrical wiring, plumbing connections, or heating systems. Sheds built closer to property lines than your zoning allows also require permits, and often a Committee of Adjustment variance application on top of that. In older Toronto neighbourhoods like The Beaches, Leslieville, or High Park, tight lot coverage restrictions mean even modest sheds can exceed allowable lot coverage percentages.

• Sheds over 10 square metres (108 sq ft) always require a permit
• Any shed with electrical, plumbing, or HVAC needs a permit
• Sheds violating setback requirements need permits plus possible variances
• Properties in heritage conservation districts have additional review layers
• Flood plain or ravine properties face extra scrutiny from TRCA

City of Toronto Shed Permit Fee Breakdown

Toronto calculates building permit fees based on construction value and floor area, with minimum fees applying to small projects. For a typical residential shed, you are looking at a base permit fee plus any applicable zoning review charges. The City updates its fee schedule periodically, so always confirm current rates before submitting.

A straightforward shed under 50 square metres that complies with zoning usually falls into the minimum permit fee category. Expect the base building permit to run between $200 and $400 for most backyard sheds. If your project requires zoning examination because it exceeds height limits, sits too close to property lines, or pushes lot coverage over the threshold, add another $300 to $600 for zoning review fees.

Additional Costs Beyond the Permit Fee

The permit fee itself is rarely the full cost. Many homeowners forget about permit drawings, which the City requires for any permitted structure. Professional permit drawings for a shed typically cost between $300 and $800 depending on complexity. At PermitsHub, we handle shed permit drawings regularly and can often bundle them with the application process to save time.

• Permit drawings: $300 to $800 depending on shed complexity
• Site plan or survey update: $200 to $500 if required
• Electrical permit (if applicable): separate fee based on circuits
• Committee of Adjustment variance: $4,000 to $6,000 if zoning relief needed
• TRCA permit: additional fee for properties near ravines or waterways

Why Some Shed Permits Cost More Than Others

Two identical sheds on different properties can have wildly different permit costs. The main factors are zoning compliance, lot location, and what services you want in the shed. A property in North York with generous setbacks and low lot coverage might breeze through with just the base permit fee. The same shed on a narrow lot in Little Portugal might require a variance application that costs more than the shed itself.

Electrical adds complexity and cost. A shed with lighting and outlets needs both a building permit and an electrical permit, plus drawings that show the electrical layout. If you want to run a sub-panel for power tools or heating, the electrical permit fees increase based on amperage. Plumbing is even more expensive to permit, and most homeowners avoid it in sheds for this reason.

The permit fee is predictable. What surprises people is discovering their shed needs a $5,000 variance because their lot coverage is already maxed out from a previous deck or addition.

How to Apply for a Shed Permit in Toronto

Toronto accepts shed permit applications through its online portal for straightforward projects. You will need to create an account, upload your permit drawings, complete the application form, and pay fees online. The City aims to review simple residential applications within a few weeks, though complex projects or those requiring zoning review take longer.

Your submission needs to include a site plan showing the shed location relative to property lines and existing structures, floor plans with dimensions, elevation drawings showing height and appearance, and construction details if the shed is custom-built. Pre-fabricated shed kits from major retailers sometimes come with permit-ready drawings, but these often need modification to meet Toronto's specific requirements.

Common Reasons Shed Permits Get Rejected

Incomplete drawings cause most initial rejections. The City wants to see exact setback dimensions, not approximations. Missing the height measurement to the peak, failing to show existing structures on the site plan, or omitting construction details all trigger requests for additional information. Each revision cycle adds weeks to your timeline.

Zoning non-compliance is the other major rejection reason. If your shed exceeds the maximum accessory structure size for your zone, sits in a required setback, or pushes your lot coverage over the limit, the building permit cannot be issued without zoning relief. This is why checking zoning before you design saves significant time and money.

Shed Permits in GTA Municipalities Outside Toronto

If your property is in Mississauga, Brampton, Vaughan, Markham, or another GTA municipality, permit requirements and fees differ from Toronto's. Each municipality sets its own fee schedule and has its own interpretation of the Ontario Building Code exemptions. Mississauga, for example, has different lot coverage calculations that can affect whether your shed triggers zoning review.

The 10 square metre exemption from the Ontario Building Code applies across Ontario, but local zoning bylaws layer on additional requirements. Some municipalities require permits for any accessory structure regardless of size if it has a concrete foundation. Others have stricter setback requirements that effectively require permits for sheds that would be exempt in Toronto. Always check with your local building department before assuming you are exempt.
