What Permits Do You Need Before Starting a Home Renovation in Ontario?

Before starting any home renovation in Ontario, it’s crucial to know which permits are required. Renovating without proper permits can lead to fines, delays, and complications when selling your home.

Common Renovation Permits in Ontario

1. Building Permit

   • Required for structural changes like removing or adding walls, finishing basements, or building extensions.

   • Ensures your renovation meets Ontario building codes.

2. Plumbing Permit

   • Needed for major plumbing work, such as relocating pipes, installing new bathrooms, or adding kitchens.

3. Electrical Permit

   • Required for rewiring, new lighting, or adding electrical outlets.

4. Demolition Permit

   • Necessary if you’re tearing down walls or removing major parts of your home.

5. Zoning and Property Use Permits

   • Ensures your renovation complies with local zoning laws, lot coverage, and property use restrictions.

6. Heritage or Conservation Permits

   • Needed for homes in heritage districts or designated conservation areas.

Tips for Navigating the Permit Process

1. Check with your local building department before starting any work.

2. Hire a licensed contractor — they can help secure the necessary permits.

3. Factor permit time into your project schedule — approvals can take weeks.

4. Keep all permit documents in case of inspections or future home sales.

5. Avoid DIY major structural, plumbing, or electrical work without permits — it’s illegal and risky.
