Do You Need a Permit for Your Home Addition?

Most home additions in Toronto require a building permit to ensure safety and compliance. Your project will likely need approval if it involves:

✅ Expanding your home’s footprint (second-story additions, rear or side extensions).

✅ Structural modifications (removing or modifying load-bearing walls).

✅ Electrical, plumbing, or HVAC system upgrades.

✅ Changes to zoning requirements (lot size, height restrictions, property setbacks).

If your addition doesn’t comply with zoning bylaws, you may need to apply for a variance before obtaining a permit.

Key Steps to Obtain a Home Addition Permit in Toronto

Step 1 – Review Zoning & Bylaws

Toronto has strict zoning regulations that dictate:

✔ Maximum building height and lot coverage.

✔ Setback requirements from property lines.

✔ Design restrictions for specific neighbourhoods.

If your project doesn’t align with zoning rules, you’ll need to apply for a zoning variance through the Committee of Adjustment, which can add time to the process.

Step 2 – Prepare Your Permit Application

To apply for a Building Permit, you will need:

• Architectural drawings detailing the proposed addition.

• Structural engineering plans (if modifying the home’s foundation or structure).

• Site plans showing property layout and the planned extension.

• Energy efficiency reports (for projects impacting insulation or HVAC).

Submitting a complete and accurate application speeds up approval time.

Step 3 – Submit Your Application to the City of Toronto

Permit applications can be submitted through Toronto’s ePlans system. Standard processing times:

• Building Permits: 10–30 business days.

• Zoning Variance (if required): 3–6 months.

Step 4 – Approval & Inspections

Once approved, you must:

✔ Display your permit on-site during construction.

✔ Schedule mandatory inspections (foundation, framing, electrical, final review).
