Why You Must Get a Bathroom Renovation Permit in 2025
Getting a Toronto bathroom renovation permit isn’t just about following rules—it’s about protecting your home, your wallet, and your future plans. Whether you’re updating plumbing, moving walls, or adding a basement bathroom, most major renovations require a permit under the Ontario Building Code. In 2025, updated regulations make it even more important to stay compliant from the start.
Without the right permit, your project could be shut down by inspectors, and you might face costly fines or delays. Worse, unpermitted work can affect your home insurance, lower your resale value, and create safety risks if something goes wrong. A valid permit ensures your renovation is inspected at key stages, so everything meets Toronto’s safety and zoning standards.
If you’re working with a contractor, make sure they understand the local building code changes coming in 2025. At BathGuys, we guide clients through the entire process—from permit applications to final inspections—so you can renovate with confidence, knowing your home is in expert hands.
What Types of Bathroom Work Require Permits?
Not every bathroom upgrade needs a permit—but when your project involves plumbing, structure, or electrical work, a Toronto bathroom renovation permit is usually required. In 2025, the city continues to follow the Ontario Building Code, which outlines exactly when permits are needed.
Work That Requires a Permit:
- Moving or adding plumbing (e.g., relocating a toilet, installing a new shower)
- Altering electrical systems (e.g., adding a new circuit, upgrading lighting)
- Changing structural elements (e.g., removing or moving walls)
- Building a new bathroom (especially in a basement or attic)
- Converting space into a secondary suite with a bathroom
Work That Usually Doesn’t Require a Permit:
- Replacing tiles, flooring, or paint
- Installing new fixtures in the same location (e.g., swapping a vanity)
- Cosmetic upgrades like mirrors, shelves, or lighting covers
Keep in mind that even if the work seems minor, certain properties—like condos or heritage homes—may have additional rules or require approval from local authorities or condo boards.
When in doubt, it’s always better to ask. BathGuys regularly helps homeowners understand whether their project needs a permit. We also make sure every step meets city and code standards, so there are no surprises down the line.
Step-by-Step Permit Process for Toronto Bathroom Projects
Applying for a Toronto bathroom renovation permit may seem overwhelming, but breaking it down into steps makes the process simple and manageable. Whether you’re hiring a contractor or planning a DIY project, following these steps ensures your renovation is legal and safe.
1. Determine if You Need a Permit
Start by assessing the scope of your project. If you’re changing plumbing, electrical systems, or structural elements, you’ll need a permit. You can check this through the City of Toronto’s Building Permit website or consult a qualified contractor like BathGuys.
2. Prepare Required Documents
You’ll need:
- Detailed floor plans and elevation drawings
- Scope of work (what exactly will be done)
- Contractor information (if applicable)
- Mechanical, plumbing, or electrical diagrams (if changing these systems)
3. Submit Your Application
Apply online through Toronto’s ePermit Portal or in person at the Toronto Building Office. You’ll need to upload all required documents and pay the applicable fees.
4. Wait for Review and Approval
City officials will review your application for compliance with the Ontario Building Code, local zoning bylaws, and safety standards. This can take a few days to several weeks, depending on the complexity of your project.
5. Receive the Permit and Begin Work
Once approved, you’ll receive a permit. You must post this on-site and ensure that all work follows the approved plans.
6. Schedule Inspections
Inspections are required at different stages (e.g., after plumbing is roughed-in, before walls are closed). These inspections confirm your renovation meets all code requirements.
7. Final Approval
After the last inspection, your permit will be officially closed. This final approval is important for resale, insurance, and legal compliance.
2025 Toronto-Specific Permit Tips & Time Savers
Renovating in Toronto means dealing with detailed city regulations—but there are smart ways to speed up the process. With the right knowledge and planning, you can avoid delays and make the most of your Toronto bathroom renovation permit application in 2025.
1. Use Toronto’s ePermit System
Skip the paperwork. In 2025, the City of Toronto’s ePermit system is faster and more user-friendly than ever. Submitting your application and drawings online reduces wait times and lets you track progress in real-time.
2. Pre-Consultation Can Save Weeks
Before submitting your application, book a pre-application consultation. This is especially helpful for complex projects (like adding a bathroom in a basement or near load-bearing walls). City staff can flag potential zoning issues early, so you avoid rejections and revision requests.
3. Know the 2025 Updates
Toronto has updated several zoning and building code guidelines for 2025. These include stricter requirements for:
- Basement bathrooms and secondary suites
- Waterproofing standards
- Energy-efficient fixture upgrades
Working with a knowledgeable contractor like BathGuys ensures your project aligns with the latest regulations, preventing back-and-forth revisions.
4. Bundle Applications When Possible
If your project includes other renovations—like kitchen or basement upgrades—submit a combined permit application. This streamlines reviews and reduces the overall processing time.
5. Hire Professionals Familiar with City Requirements
Experienced contractors can reduce errors, speed up inspections, and avoid common delays. BathGuys manages all paperwork, drawings, and inspections for clients, ensuring every step meets Toronto’s 2025 requirements.
