How Long Does a Toronto Deck Permit Take, and What Does It Cost?
Budget $200 to $600 for the permit itself (the base residential fee is around $206, with larger projects priced on declared value) and 2 to 8 weeks from application to approval. The City's standard review target is 10 business days for a clean application, but revisions, zoning issues, heritage review, or ravine/TRCA involvement stretch real-world timelines. Drawings are the other cost most homeowners forget: professional permit drawings run several hundred to a couple thousand dollars if your contractor doesn't include them.
The real cost breakdown
| Item | Typical cost |
|---|---|
| Building permit fee | $200 - $600 (based on declared value) |
| Permit drawings (site plan + construction drawings) | $500 - $2,000 if not included by your builder |
| Property survey (if you don't have a current one) | $1,500 - $2,500 |
| Engineering (elevated/complex decks) | $500 - $1,500 |
| Minor variance (if you exceed zoning limits) | Several thousand dollars and months of time |
A straightforward attached deck with an existing survey and a contractor who includes drawings usually lands at just the permit fee. The expensive scenarios are missing surveys and zoning problems.
The timeline, step by step
- Prepare documents (1-2 weeks). Property survey, site plan showing the deck's location and setbacks, dimensioned construction drawings (footings, beams, joists, guards, stairs), and material specs. Engineer-sealed drawings need an Assumption of Responsibility form.
- Apply online. Toronto processes applications through its online portal (Cloudpermit). Fees are paid on submission.
- City review (10 business days standard). Clean applications can clear in that window. Comments or deficiencies restart the clock on each resubmission.
- Build. Post the permit visibly, keep approved drawings on site.
- Inspections. Typically footing inspection before concrete is poured, then final inspection. Your builder schedules these.
- Close the permit. Make sure the final inspection is passed and the permit closed; open permits resurface during home sales.
What slows applications down
- Incomplete drawings. The number one cause of comment cycles. Every dimension, footing, and guard detail the reviewer needs should be on the page.
- Zoning conflicts. Setback or lot-coverage problems mean redesign or a minor variance, which is a separate, slower process.
- Heritage listing. Add 30-60 days for Heritage Planning where applicable.
- Ravine/TRCA lots. Conservation approvals run on their own timelines.
- Season. Spring is peak season for applications. A winter application meets a quieter queue and has your permit ready for the first thaw.
The smart sequencing
Apply in January-March, build in April-May. You skip the spring permit rush, and builders' early-season calendars are still open. Leaving the permit to May often means enjoying your new deck in August instead of June.
From our side of the process: the difference between a fast permit and a slow one is almost never the city, it's the application. A complete drawing set that answers every question a reviewer could ask tends to move straight through. An application with a missing dimension or a vague footing detail earns a comment letter, and every comment letter restarts the clock. That's why we'd rather spend a few extra days getting the drawings right than win those days back one resubmission at a time, and why we steer clients toward off-season applications, when the queue is short and a comment cycle costs days instead of weeks.
FAQ
Can my contractor pull the permit for me? Yes, and good ones do it routinely, including drawings. Confirm it's in your quote and confirm the permit gets closed at the end.
Do I need an architect for deck drawings? No. Drawings must be complete and code-compliant, but for typical residential decks a qualified designer or experienced contractor produces them. Engineering comes in for elevated or unusual structures.
What if I already built without a permit? You can apply to legalize the structure. Expect drawings of the as-built deck, possible exposure of footings for inspection, and modifications if anything falls short of code. It's cheaper than a demolition order, but far more painful than permitting upfront.
Does the permit expire? Permits lapse if work doesn't start within a set period (and after long inactivity). If your project slips a season, check your permit's status before resuming.
