If you've ever tried to read the City of Toronto's official fee schedule, you know it reads like a tax return crossed with a spreadsheet. Service indices, hourly examination rates, Part 9 vs. Part 3 — it's a lot.
So let's cut through it. Here's what Toronto building permits actually cost in 2026, in plain English, for the projects real homeowners actually do.
What Changed in 2026?
Effective January 1, 2026, all Toronto building permit fees went up by 4% — the annual Cost of Living Adjustment. That means every rate, every flat fee, and every minimum just got a little pricier.
The good news? For most small residential projects, we're still talking hundreds of dollars — not thousands.

The Minimum Fee: $214.79
Here's the number to remember: $214.79. That's the minimum permit fee for any work in Toronto in 2026. A lot of common projects — decks, sheds, detached garages, basic HVAC — land right at that flat fee.
If your project is small enough, $214.79 is your total permit cost.
How Toronto Calculates Permit Fees
For larger projects, the City uses a formula:
Permit Fee = Service Index (SI) × Floor Area (m²)
The "Service Index" is a rate per square metre that varies by building type and work type. For a single-family home, the 2026 rate is $18.56/m². For interior alterations, it's $11.53/m². For basement finishing, just $6.20/m².
If the formula result is less than $214.79, you pay $214.79.
What Common Projects Actually Cost
Here's what real homeowners in Toronto can expect to pay in permit fees for 2026:
| Project | Permit Fee (2026) |
|---|---|
| Deck or porch | $214.79 (flat) |
| Detached shed or garage | $214.79 (flat) |
| Pool fence enclosure | $214.79 (flat) |
| Furnace/boiler replacement | $214.79 (flat) |
| A/C unit addition | $214.79 (flat) |
| Full HVAC (heating + A/C) | $270.64 (flat) |
| Basement finishing (93 m² / 1,000 sq ft) | ~$577 |
| Interior renovation (46 m² / 500 sq ft) | ~$531 |
| Addition (37 m² / 400 sq ft) | ~$687 + $56.33/unit |
| New single-family home (186 m² / 2,000 sq ft) | ~$3,452 + $56.33/unit |
| Garden or laneway suite (56 m² / 600 sq ft) | ~$1,096 + $56.33/unit |
| Re-roofing, non-structural (186 m² / 2,000 sq ft) | ~$214.79 (min) |
Note: These are permit fees only. They don't include your Zoning Applicable Law (ZAP) certificate, design costs, or professional drawings.
Don't Forget the ZAP Certificate
For anything beyond simple interior work, you'll likely need a Zoning Applicable Law Certificate — and it has its own fee:
| ZAP Type | 2026 Fee |
|---|---|
| Accessory structures (garages, porches) | $214.79 |
| New house, additions, alterations | $644.38 |
| New laneway or garden suite | $644.38 |
| Non-house buildings ≤300 m² | $888.14 |
| Non-house buildings >300 m² | $1,863.82 |
Without a ZAP, your application is considered incomplete — and incomplete applications have no guaranteed review timeline. That's the #1 reason permits get delayed.
Plumbing Fees Add Up Quickly
If your renovation involves plumbing, budget for these on top of the base permit:
- Plumbing fixtures (single-family): $23.20 each
- Water services / buried piping: $214.79 flat
- Backwater valves: $38.67 each
- Backflow prevention devices: $92.79 each
A bathroom reno with a new toilet, sink, and shower? That's about $70 in plumbing permit fees on top of whatever the building permit costs. Not bad — but it catches people off guard when they don't expect it.
The Penalty You Want to Avoid
Here's the fee that should scare you: the construction-without-permit surcharge.
If you build without a permit and get caught, the City charges an additional 50% of the permit fee (minimum $214.79, maximum $29,456.99). That's on top of having to retroactively apply, potentially tear out work, and deal with all the other consequences.
A $214.79 deck permit becomes $322+ after the surcharge. A $3,452 new-home permit becomes $5,178+. It's not worth it.
How to Pay
Toronto accepts:
- Credit card (Visa, Mastercard, Amex) — up to $20,000
- EFT / wire transfer — for larger amounts
No cheques. No Interac e-Transfer. Plan accordingly.
How to Save on Permit Costs
The permit fee itself is non-negotiable — it's set by the City. But you can save on the overall process:
- Submit a complete application the first time. Resubmissions cost time and sometimes additional fees.
- Use Express Services for qualifying projects. Decks, sheds, garages, interiors, and standalone plumbing get 3-day review — no wasted time.
- Check if you even need a permit. Some projects are exempt. Use our free permit checker before spending a dollar.
- Consider a permit service. The time savings alone can pay for itself, especially if you're comparing DIY vs. professional help.
