Building a deck is one of the most popular home projects in Toronto — and one of the most common to get wrong on the permit side. The good news: deck permits are straightforward, cheap, and fast. The bad news: skipping the permit (or botching the application) can cost you way more than the $214.79 fee.
Here's your complete checklist for getting a deck permit in Toronto in 2026.
Do You Even Need a Deck Permit?
Not every deck requires a permit. Here's the rule:
You NEED a permit if:
- The finished deck level is more than 60 cm (24 inches) above adjacent finished grade, OR
- The deck is attached to the house, OR
- The deck forms part of a required exit (e.g., a second-floor exit)
You DON'T need a permit if:
- It's an uncovered platform
- The finished level is 60 cm or less above grade
- It doesn't form part of a required exit
- It complies with all zoning requirements
In practice, most backyard decks in Toronto need a permit. If your yard slopes and any part of the deck is more than 24 inches off the ground — which is common — you need a permit.

What It Costs
Permit fee: $214.79 (flat fee for residential decks, porches, and carports in 2026)
That's it. No per-square-metre calculation, no add-ons. Just the flat minimum fee.
If you build without a permit and get caught, the City adds a 50% surcharge — making it $322+ instead of $214.79. Don't risk it.

The Express Advantage: 3-Day Review
Decks qualify for Express Services (formerly FASTRACK). That means the City targets a review within 3 business days after intake — compared to 10+ days for projects that go through House Stream.
After approval, the permit is typically issued within 1 business day of payment. So from submission to permit in hand: roughly 1 week if everything is in order.

Your Deck Permit Checklist
Here's everything you need to prepare before submitting:
☐ 1. Application Form
Use the Application for a Permit to Construct or Demolish. As of February 16, 2026, you must use the updated version — the old form will be rejected.
Download from the Toronto Building Forms Index.
☐ 2. Site Plan
A drawing of your property showing:
- Property boundaries with dimensions
- Location of your house on the lot
- Proposed deck location with dimensions
- Setbacks from all property lines (front, rear, side)
- Any existing structures (sheds, garages, pools)
The site plan doesn't need to be professionally drafted for a deck, but it must be to scale and clearly show all measurements.
☐ 3. Deck Drawings
Include:
- Plan view (top-down) showing deck dimensions, post locations, and beam layout
- Elevation/section view showing height above grade, post depth, beam sizes, joist sizes, and railing height
- Details of post footings, connections, and railing/guard construction
For a standard residential deck, these can be hand-drawn as long as they're clear, dimensioned, and show the structural details.
☐ 4. Structural Details
Your drawings should show:
- Post footings: Depth below grade (must be below frost line — 1.2 m / 4 feet in Toronto)
- Post sizes and spacing
- Beam sizes
- Joist sizes and spacing
- Ledger board connection (if attached to house)
- Guard/railing height: Minimum 1.07 m (42 inches) for decks more than 60 cm above grade per OBC Section 9.8
☐ 5. Zoning Compliance Check
Before submitting, confirm your deck complies with zoning:
- Setbacks: Your deck must meet minimum distances from property lines. These vary by zone — check your property's zoning designation.
- Lot coverage: The deck adds to your total lot coverage. If you're already close to the maximum, the deck might push you over.
- Height: Generally not an issue for decks, but second-storey decks need careful review.
Pro tip: For Express Services, a formal ZAP certificate is typically not required for simple decks. But if you're close to setback limits, getting zoning clarification upfront avoids problems.
☐ 6. TRCA Check (If Applicable)
If your property is in a Toronto and Region Conservation Authority (TRCA) regulated area — typically near ravines, rivers, or the waterfront — you may need a separate TRCA permit. Check the TRCA mapping tool before you apply.
☐ 7. Submit Online
Deck permits are submitted through Toronto's online portal for Express Services.

Upload your application form, site plan, and deck drawings. You'll get a confirmation and intake notification.
Common Deck Permit Mistakes
These are the issues that delay or derail deck permits. Avoid them:
1. Ignoring Setback Requirements
Your deck can't sit right on the property line. Every zone has minimum setback distances, and decks count. Check before you design — it's much easier to adjust the deck size on paper than after you've poured footings.
2. Forgetting Lot Coverage
Toronto's zoning by-law limits how much of your lot can be covered by structures. Your house, garage, shed, AND deck all count toward this limit. If you're at 35% coverage and the limit is 35%, your new deck pushes you into non-compliance — and your permit will be denied.
3. Underestimating Height Above Grade
Yards in Toronto often slope. The front of your deck might be 18 inches above grade, but the back could be 36 inches. If any part exceeds 60 cm, you need a permit. Measure from the lowest adjacent grade, not the highest.
4. Skipping the Railing Details
Guards (railings) are a code requirement for decks more than 60 cm above grade. They must be at least 1.07 m (42 inches) high, and the spacing between balusters can't exceed 100 mm (4 inches). Missing or incorrect railing details are a common deficiency note from examiners.
5. Ignoring the Ledger Connection
If your deck is attached to the house, the ledger board connection is critical — it's how the deck transfers load to the house structure. A poorly detailed ledger connection is both a code issue and a safety issue. Show the connection method clearly in your drawings.
6. Building Before the Permit Is Issued
Submitting your application is not the same as having a permit. Don't start construction until you have the actual permit in hand. Starting before approval can result in a stop-work order and the 50% surcharge.
After You Get the Permit
Once your permit is issued:
- Post the permit on your property in a visible location during construction
- Build according to the approved drawings — no freelancing
- Book inspections at required stages (typically footing/foundation and final)
- Close the permit after final inspection approval
An open permit stays on your property's record forever — and it will show up when you sell. Always close your permits.
