Ultimate Guide to Renovation Permits in Toronto & GTA

1. Do You Need a Permit?

Any work that involves:

• Structural changes (moving walls, foundations, decking, etc.)

• Altering exterior envelopes (windows, siding)

• Major systems (electrical, plumbing, HVAC)

• Changing use or occupancy

requires a permit under the Ontario Building Code and local bylaws. If it's just cosmetic—like painting or flooring—no permit is needed

2. How Much Do Permits Cost?

City of Toronto Permit Rates

• Minimum base fee: CA$206.53 (2025) for any scope
• Inspection & review: $89.22/hr.
• Fee-by-area formula: Permit Fee = Service Index (SI) × area (m²)
• Interior reno SI = 4.93/m², additions SI = 17.16/m² .
• Example: 50 m² basement → 50 × 4.93 = CA$246.50, plus the $206 minimum.
• Kitchen/bathroom additions (100 m²): 100 × 17.16 = CA$1,716.
• Zoning fee: Additional 25% of permit cost for new/additions
• After-the-fact fee: 50% surcharge on permit fees if unpermitted work detected
