Thinking about updating your bathroom? Before you start swinging a hammer, you need to understand Ottawa’s renovation permit process.
Ignoring permits slows projects down. It costs more. It can lead to fines or forced removal of work. All this can be avoided. Here’s how.
When You Need a Permit
You need a permit if your bathroom renovation project includes:
Moving plumbing (e.g., changing the location of a toilet or sink)
- Building or removing walls
- Structural changes
- Adding a bathroom to a new space (e.g., basement)
- Installing new windows or enlarging existing ones
You don’t need a permit for cosmetic updates like:
- Replacing tiles
- Painting
- Swapping fixtures without moving them
The best way to decide whether in you need a permit is to ask yourself: am I changing the structure, layout, or plumbing? If yes, you need a permit.
Where to Apply
Apply through the City of Ottawa’s Building Code Services. You can submit online through ottawa.ca.
They also offer in-person help at the Client Service Centres.
What You Need to Submit
Have this ready:
- Floor plans (existing and proposed)
- Mechanical plans if you’re changing plumbing or ventilation
- Permit application form
- Project description
Plans must be to scale and detailed.
Permit Fees
For a bathroom renovation in Ottawa:
- Minimum permit fee: $114
- Plumbing fee: $13 per fixture (e.g., sink, toilet, tub)
- Review surcharge may apply if resubmissions are needed
Common Mistakes to Avoid
- Skipping the permit: City inspectors do random checks. Neighbours complain. If caught, you’ll pay double.
- Not checking zoning rules: Basement bathrooms in some zones require extra ventilation or waterproofing standards.
- Inadequate drawings: Vague or messy plans delay approval.
- Hiring unlicensed contractors: If your contractor doesn’t pull the right permits, you’re still responsible.
- Starting before approval: Never start work before the City signs off.
How Long Approval Takes
Average turnaround:
- 5 business days for standard residential projects
- Delays if your plans need corrections
Plan ahead. Don’t assume you’ll get approved the same week.
Inspections You’ll Need
At minimum:
- Rough-in plumbing
- Framing (if walls are added)
- Final inspection before use
Book inspections at each stage through your MyServiceOttawa account.
Real Example
A homeowner in Nepean added a basement bathroom. They started without a permit. A neighbour tipped off the City. The homeowner had to rip out finished drywall, pay double permit fees, and delay the project by two months. It could be avoided.
If your project involves plumbing or structural work, start with permits. It saves time. It protects your investment. It keeps you on the right side of the law.
