Building Permit Costs in the GTA: 2026 Breakdown
In this article
The number on your permit invoice is rarely the only number you pay. Homeowners across the GTA permit drafting regularly tell us they were quoted “around $1,500 for the permit” and ended up paying three or four times that by the time the project was permit-ready. The fees are straightforward once you know what’s on the list. Here’s the 2026 breakdown for the most common residential permit types in Toronto and the surrounding municipalities, plus the line items most quotes leave out.
What you’re actually paying for
A building permit fee is a per-square-metre charge, not a flat fee. Toronto Building bases its 2026 residential permit on the floor area of new or altered space, with a minimum fee that catches small jobs. On top of the building permit there are usually plumbing, HVAC, and (separately through ESA) electrical permits, plus a deposit that gets refunded after final inspection.
Toronto residential permit fees in 2026
These ranges are the actual permit fees only. They don’t include the items below.
The fees that catch homeowners off guard
- Development charges. Toronto residential development charges in 2026 can add $25,000 to $90,000 for new dwelling units, including secondary suites in some cases. The city has phased in exemptions for ARUs but the rules change yearly. Confirm before you commit.
- Parkland dedication or cash-in-lieu. Triggered on new dwelling units. Several thousand dollars to tens of thousands.
- Education development charges. Separate from city DCs, billed by the school boards.
- Security deposit. Refundable but Toronto holds 2 to 5 percent of construction value until final inspection passes.
- Demolition permit. Separate fee if you’re tearing anything down, including an existing garage.
- Tree protection or removal permits. Required for any city-owned tree within 6 metres of the work area, and for private trees over 30 cm DBH in Toronto.
- Heritage permit fees. Add a fee and add weeks if you’re in a Heritage Conservation District.
- Committee of Adjustment fees. Roughly $2,500 for a standard residential minor variance application in Toronto in 2026.
- Conservation Authority fees. If you’re near a regulated area, you’ll pay TRCA or another CA for review.
- ESA electrical permit. Separate from the building permit, billed directly by the Electrical Safety Authority.
- TSSA gas inspection. If you’re touching any gas appliance or gas line.
Mississauga, Vaughan, and the 905 in 2026
Permit fees are competitive across the GTA but development charges are not. City of Mississauga Building runs slightly lower building permit fees than Toronto for equivalent scopes but the regional development charge (Peel Region) is steep. Vaughan Building Standards is similar. If you’re planning a project in Mississauga permit drawings or Vaughan permit drawings, run the development charge calculation before the design is final, because adding a second unit to a project can flip the math.
Designer and engineer fees: what to budget
Permit drawings, structural calculations, and energy compliance reports are not city fees, but they’re permit costs. Typical 2026 ranges for residential work in the GTA:
- Permit drawings for a renovation: $1,800 to $4,500
- Permit drawings for an addition: $3,500 to $8,000
- Permit drawings for a new house: $7,000 to $18,000
- Structural engineer review and seal: $800 to $2,500 depending on scope
- Energy compliance (SB-12): $300 to $700
- Surveyor’s Real Property Report: $1,200 to $2,800
- Soil report (if required for underpinning or new builds): $1,500 to $3,500

How to keep costs predictable
- Get a written scope before drafting. Vague scopes lead to scope creep and revision fees.
- Confirm development charge exposure early. One question to the city saves five-figure surprises.
- Bundle related permits. Don’t pull a separate permit for the deck if it’s part of the addition.
- Avoid Committee of Adjustment if you can design within zoning. The cost of a redesign is usually less than the cost of a variance hearing.
- Use a designer familiar with your city. Local examiner familiarity reduces revision rounds, and revision rounds cost money.

Frequently asked questions
Are permit fees the same across the GTA?
No. Each municipality sets its own rates and adjusts them annually. Toronto fees are typically the highest, followed by Mississauga and Vaughan, with smaller 905 municipalities running lower.
What’s the difference between a permit fee and a development charge?
The permit fee covers the city’s review and inspection costs. Development charges fund infrastructure for new dwelling units and apply mainly to additions that add bedrooms or new units. Development charges can dwarf the permit fee on a second unit project.
Do I need to pay drafting and engineering costs on top of the permit fee?
Yes. The permit fee is just the city’s portion. Drafting fees for residential projects in the GTA in 2026 typically run from $1,500 for a basement permit to $8,000+ for a custom home. Structural engineering adds $800 to $3,500 depending on the scope.
Can I avoid permit fees by skipping the permit?
No. Working without a permit triggers double fees plus a stop-work order, and the city can require demolition of unpermitted work. The risk is never worth the savings.
