What Permits Do You Need for a Bathroom Renovation in Toronto?

Thinking of giving your bathroom a facelift? Whether you’re adding a new shower, moving your sink or redoing the whole space, it’s exciting to start a renovation. But before you grab a hammer, there’s one important step many Toronto homeowners overlook — getting the right bathroom renovation permits in Toronto.

Knowing what permits you need can save you from fines, delays and even having to redo your renovation. In this blog we’ll walk you through all the permits required for a bathroom renovation in Toronto, when you need them and how BathGuys make the process easy and painless.

Do You Need a Permit for a Bathroom Renovation in Toronto?

So you’re planning a bathroom remodel in Toronto and your first question is, “Do I need a permit?” The answer is, it depends on the work you’re doing. Not all bathroom upgrades require a permit — but when you’re changing plumbing, electrical systems or the room’s layout the City of Toronto requires you to get approval before you start.

When You Do Need a Permit

You’ll need a bathroom renovation permit in Toronto if your project includes:

• Moving or adding plumbing fixtures like sinks, toilets or showers
• Changing the bathroom’s layout or removing walls
• Installing new electrical wiring or outlets
• Replacing or adding ventilation systems or exhaust fans
• Expanding the bathroom or adding new structural features

These changes affect the safety and structure of the home so they must follow the Ontario Building Code and Toronto building regulations. Getting the right permit means your renovation will be inspected and approved by the city.

When You Don’t Need a Permit

You usually don’t need a permit for small or cosmetic updates like:

• Replacing tiles, flooring or paint
• Installing new vanities or faucets in the same position
• Upgrading light fixtures (without changing wiring)
• Adding décor or mirrors

These are minor improvements that don’t change the plumbing or structure of the bathroom.

Why it is important

Skipping permits might seem like a quick shortcut but it can lead to fines, delays and even problems when you sell your home. Insurance claims can also be denied if unpermitted work causes damage later. That’s why it’s always best to check with Toronto Building Services before you start any major renovation — or simply hire professionals like BathGuys, who handle all permit requirements for you.

Types of Bathroom Renovation Permits in Toronto

Before you start your bathroom renovation in Toronto, its a good idea to get a handle on the various permits you will need. The type and number of permits required will depend on exactly what work you are planning to do. Getting a handle on this early on can save you a world of hassle down the line – avoided delays, failed inspections, and unexpected costs.

Below are the main types of permits you’ll need for a bathroom renovation in Toronto:

1. Building Permit

You’ll need a building permit if you’re planning to make any major changes to the layout or structure of your bathroom. This means moving walls around, changing the size of doors or windows, or even adding on a new room.

• Who issues it: The good folks at the Toronto Building Division
• Why is it important: Its all about following the rules, ie the Ontario Building Code, to make sure your renovation is safe and accessible.
• When you can skip it: If you’re only upgrading the finishes like tiles, paint, or cabinets. No permit needed in that case.

2. Plumbing Permit

If you’re planning to move, add or replace any plumbing fixtures – like a toilet, shower or bathtub – you’ll need a plumbing permit.

• Who can do the paperwork: Only a licensed plumber will do
• Why do you need it: Its a check to make sure any new plumbing work meets our local safety and sanitation standards
• Rule of thumb: Even if you’re just replacing a toilet in the same spot, if you move it to a different part of the bathroom, you’ll need a permit.

3. Electrical Permit

Whether you’re just adding some new outlets or putting in a fancy new vanity light, any electrical work in your bathroom requires an electrical permit.

• Who issues it: That’s the Electrical Safety Authority (ESA) in Ontario for you
• Who does the filing: A licensed electrician or electrical contractor will take care of this for you
• Why does it matter: Well, its all about safety, reducing the risk of electrical fires or shocks, especially in a bathroom where things get nice and damp.

4. HVAC or Ventilation Permit

If you’re planning on installing or moving an exhaust fan or ventilation duct, you might need an HVAC permit (Heating, Ventilation, and Air Conditioning).

• What its for: Its all about maintaining good airflow and stopping moisture from building up or causing mold to grow
• Who does the paperwork: Usually your trusty HVAC tech or contractor

How to Apply for a Bathroom Renovation Permit in Toronto

Getting a bathroom renovation permit in Toronto seems complicated but it’s really a straightforward process once you know the steps. The City of Toronto requires homeowners to follow certain procedures to ensure all work meets local safety and building standards. Here’s how to do it:

Step 1: Find Out Which Permits You Need

First, figure out what permits your project requires.

• A building permit is needed for any structural changes like removing walls or changing your bathroom’s layout.
• A plumbing permit is required if you’re moving drains, sinks, showers or toilets.
• An electrical permit is needed if new wiring or lighting is being installed.

If you’re not sure which permits apply, contact Toronto Building or consult your renovation contractor — professionals like BathGuys can assess your project and handle the paperwork for you.

Step 2: Prepare Your Application and Drawings

Next, gather your construction drawings and plans. These must show your existing bathroom layout and proposed changes. Make sure they’re accurate — incorrect or missing details are a common reason applications get delayed.

You’ll also need:

• Your property address and ownership details
• The completed Toronto Building Permit Application Form
• Supporting documents like plumbing diagrams (if applicable)

Step 3: Submit Your Application Online

The City of Toronto makes it easy to apply through the Toronto Building eServices portal. Upload your drawings, fill in the required information and pay your permit fees online. Once submitted you’ll get a confirmation email and an application number.

Step 4: Pay the Required Fees

Permit fees in Toronto are based on the size and value of your renovation project. For most small bathroom remodels, fees are around $200 to $500. This may increase if multiple permits (like plumbing or electrical) are required.

Always check the current fee schedule on the City of Toronto’s website, rates change regularly.

Step 5: Wait for Review and Approval

After submission a city building official will review your application. They’ll check if your renovation meets building codes, zoning by-laws and safety standards. Most residential permits are approved within 2–4 weeks depending on complexity.

Step 6: Schedule Inspections During the Project

Once approved keep the permit on site. You’ll need to schedule inspections at specific stages — like after plumbing rough-ins or before walls are closed.

What Happens If You Renovate Without a Permit in Toronto?

Starting a bathroom remodel without the right bathroom renovation permits in Toronto seems like a shortcut — but it can quickly become a costly mistake. The City of Toronto takes permit rules seriously and skipping them can lead to big financial and legal problems.

Here’s what can happen if you renovate without a permit:

• Stop Work Orders: City inspectors can issue an immediate Stop Work Order and you’ll have to stop construction until the proper permits are obtained. This will delay your project and cost more.
• Fines: Homeowners can be fined up to $25,000 for individuals or more for repeat offences under the Toronto Building Code Act. That’s more than the cost of getting a permit in the first place.
• Retroactive Permits (After-the-Fact Applications): You may have to apply for a retroactive permit which is often more expensive and complicated. Inspectors will require proof that all plumbing, electrical and structural work meets safety standards.
• Tear-Down Requirements: In some cases you may have to open up finished walls or remove new fixtures so city inspectors can check hidden work like pipes or wiring.
• Insurance and Resale Problems: If you ever file a home insurance claim or sell your house, unpermitted renovations can cause big problems.
  • Insurance companies may deny coverage for damages related to unapproved work.
  • Home buyers and real estate lawyers will ask for proof of permits — missing documentation can reduce your home’s value or delay the sale.
