Do You Need a Building Permit for Your Renovation?
In Ontario, many renovation projects require a building permit. Working without one can result in fines, insurance issues, and problems when selling your home. Here's everything you need to know.
When You NEED a Permit
- Any structural changes (removing or adding walls, beams, posts)
- Adding or modifying a bathroom or kitchen
- Basement finishing or conversion to a secondary suite
- Adding a room, deck over 2 feet high, or garage
- Changing the use of a space (e.g., garage to living space)
- HVAC, plumbing, or electrical work (separate trade permits)
- New windows or doors that change opening sizes
- Roofing changes that affect structure
When You Typically DON'T Need a Permit
- Cosmetic updates: painting, wallpaper, flooring replacement
- Cabinet replacement (same location)
- Countertop replacement
- Like-for-like fixture replacements
- Minor repairs and maintenance
- Fences under 2 metres (check local bylaws)
The Permit Application Process
Step 1: Pre-Consultation. Many municipalities offer free pre-consultation to discuss your project before you apply. In Brantford, contact the Building Department at City Hall.
Step 2: Prepare Documents. You'll need: completed application form, site plan, floor plans (existing and proposed), structural drawings (if applicable), and the applicable fees.
Step 3: Submit & Review. Submit your application to the local building department. Review typically takes 10–20 business days for residential projects.
Step 4: Permit Issued. Once approved, you'll receive your building permit. Post it visibly at the job site.
Step 5: Inspections. Various inspections are required during construction: framing, plumbing rough-in, electrical rough-in, insulation, and final inspection.
Permit Costs in Ontario
Fees vary by municipality but typically range from $200–$2,000 for residential renovations, based on the project's estimated construction value.
