Introduction
Thinking about giving your bathroom a fresh new look? Whether it’s a simple upgrade or a full remodel, many homeowners don’t realize that certain permits are required for a bathroom renovation in Toronto. Skipping this step could lead to costly fines, inspection delays, or even trouble when selling your home.
In this blog, we’ll walk you through everything you need to know about bathroom renovation permits in Toronto—from when you need one to how to apply. With the right planning, you can stay on the right side of the law, avoid unexpected surprises, and enjoy a smoother renovation from start to finish.
Why You Need Permits for Toronto Bathroom Renovations
Getting the right permits for a bathroom renovation in Toronto is more than just paperwork—it’s about protecting your home, your safety, and your investment. The City of Toronto requires permits for any work that affects your home’s structure, plumbing, or electrical systems. These permits ensure the renovation meets the Ontario Building Code, which is designed to keep your home safe and up to standard.
Failing to get the proper permits can lead to serious problems. You might face delays, fines, or even be forced to undo completed work. Worse yet, your home insurance may not cover damages if unpermitted work is involved. This becomes especially risky when selling your home—buyers and home inspectors often check for permits, and missing paperwork could reduce your property’s value or delay a sale.
Permits also mean professional inspections. This gives you peace of mind that your bathroom renovation has been done right—from secure plumbing connections to safe electrical wiring. In the long run, following Toronto’s permit rules ensures that your renovation is not only beautiful but also legal, safe, and long-lasting.
What Specific Permits Are Required?
When planning a bathroom renovation in Toronto, it’s important to know which permits you’ll need based on the type of work you’re doing. The City of Toronto has clear rules to make sure that all renovations meet safety and building standards.
1. Building Permit (Structural Work)
If your renovation involves removing or adding walls, changing the layout, or enlarging the space, you’ll need a building permit. This is required for any work that affects the structure or load-bearing components of your home.
Examples that require a building permit:
- Removing or moving interior walls
- Adding a window or skylight
- Expanding the bathroom footprint
2. Plumbing Permit
You’ll need a plumbing permit in Toronto if you’re moving or installing new plumbing fixtures like a toilet, bathtub, or sink. Even relocating a drain or water line requires approval.
Common plumbing changes that need a permit:
- Moving a bathtub or shower
- Installing a new toilet location
- Adding or relocating water supply or drain pipes
3. Electrical Permit (ESA Certificate)
For any electrical upgrades, such as new outlets, lighting fixtures, heated floors, or exhaust fans, you’ll need a permit from the Electrical Safety Authority (ESA). This ensures the electrical work is safe and meets Ontario’s code.
Electrical work that needs a permit:
- Installing heated flooring
- Adding GFCI outlets near sinks
- New or relocated light fixtures or switches
4. Mechanical Permit
If your renovation includes updates to your ventilation system, such as adding a bathroom fan or connecting to HVAC ductwork, a mechanical permit may be required. This is especially important for proper airflow and moisture control.
When Permits Are Not Required
Not every bathroom update requires approval from the city. In Toronto, permits for a bathroom renovation are usually needed only when structural, plumbing, or electrical changes are involved. If you’re planning minor cosmetic improvements, you may be able to skip the paperwork altogether.
Common Updates That Don’t Require Permits in Toronto:
- Replacing tiles, countertops, or flooring
- Painting or wallpapering
- Installing a new vanity in the same location
- Replacing a toilet, tub, or faucet—without changing plumbing lines
- Upgrading mirrors, shelves, or towel bars
- Changing light fixtures (if wiring remains unchanged)
These cosmetic upgrades help refresh your bathroom’s look without altering its structure or systems, so they’re generally considered safe to do without permits. However, if you’re unsure whether your changes might involve plumbing or electrical work, it’s always a good idea to consult with a licensed contractor or the City of Toronto’s building department.
Remember, even if a permit isn’t required, your renovation should still follow basic building and safety standards. Hiring a qualified contractor ensures the job is done properly—even for small projects.
How to Apply for Permits in Toronto
If you’re planning a bathroom renovation in Toronto that involves structural, plumbing, or electrical work, applying for the proper permits is essential. Fortunately, the City of Toronto has made the process more accessible through online services and clear steps.
Step 1: Define the Scope of Your Renovation
Before applying, clearly outline what your renovation includes. Are you moving plumbing lines? Knocking down walls? Installing new lighting? Understanding your scope helps determine which permits you need—building, plumbing, electrical, or mechanical.
Step 2: Prepare Required Documents
You’ll need to submit specific documents, which may include:
- Floor plans and drawings (before and after renovation)
- Construction details and material specifications
- Contractor or engineer credentials (if applicable)
These drawings should show dimensions, locations of fixtures, and any changes to the structure or systems.
Step 3: Submit Your Application Online
In Toronto, you can apply for most renovation permits through the Toronto eServices portal. Visit toronto.ca/building-permits to get started.
Once submitted, your application will be reviewed for compliance with the Ontario Building Code and local bylaws.
Step 4: Pay Permit Fees
Permit fees vary depending on the scope and size of the project. Most bathroom renovation permit fees in Toronto range from $150 to $500, depending on what work is being done.
Fees may apply per type of permit (e.g., separate fees for plumbing and electrical work), and are calculated based on the value of construction or type of alteration.
Step 5: Schedule Inspections
After your permits are approved and work begins, you’ll need to book inspections at key stages:
- Rough-in Inspection: For plumbing and electrical before walls are closed
- Framing/Structural Inspection: If walls or supports were changed
- Final Inspection: Ensures all work is completed to code
These inspections help confirm your renovation meets all safety and legal standards.
Permit Fees & Costs in Toronto
When planning a bathroom renovation in Toronto, it’s important to budget not only for materials and labour—but also for the required permit fees. These costs vary based on the type and scope of the renovation, but understanding the basics can help you plan with confidence.
How Permit Fees Are Calculated
The City of Toronto typically calculates permit fees based on:
- The type of work (structural, plumbing, electrical, etc.)
- The value of the renovation (total construction cost)
- Whether the application includes multiple permit types
Fees are charged per permit category, so if your bathroom renovation includes electrical and plumbing changes, you may need to pay for each separately.
Conclusion
Planning a bathroom renovation in Toronto is an exciting opportunity to improve both comfort and home value. But without the right permits, your project could face legal issues, fines, or failed inspections. Whether it’s a plumbing permit, electrical upgrade, or structural work, understanding what’s required ensures everything is done safely and up to code. Taking the time to secure proper renovation permits in Toronto protects your investment and gives you peace of mind.
