How to Get a Building Permit in Toronto: The Step-by-Step Checklist
The City of Toronto website is text-heavy and confusing. Our visual guide makes it simple.
Why This Matters
Building without a permit in Toronto can result in stop-work orders, fines up to $100,000, and complications when selling your home. A rejected application wastes time and money. Get it right the first time.
The Toronto Building Permit Process
Determine If You Need a Permit
Not all work requires a permit. Check our complete list of exemptions.Check Zoning Requirements
Before applying, verify your project complies with zoning bylaws. You may need a Zoning Certificate or apply for a variance through the Committee of Adjustment. .
Prepare Your Drawings & Documents
You'll need architectural drawings prepared by a licensed professional. For most residential work, a BCIN-qualified designer is sufficient. Larger projects may require a licensed architect.
Submit Your Application
Apply online through the City's portal or in person. Include all required forms, drawings, and fees. Incomplete applications are the #1 cause of delays.
Wait for Review & Approval
Complete applications for detached, semi-detached, or row houses fall under the "House Stream,"which targets a 10 business day review.
Complex projects or those with zoning issues can still take 20-30+ business days.
Tip: Doing a simple deck or shed? Check if you qualify for the 3-day Express Service.
