Planning a Bathroom Renovation
A bathroom renovation starts with the existing wet areas, ventilation, layout and the interfaces between waterproofing and finishes.
Do I Need a Permit to Renovate My Bathroom in Ottawa?
Direct answer
The permit question depends on what changes. Ottawa lists cabinet replacement as exempt if plumbing fixtures remain in the same location, and lists painting, decorating and new flooring as exempt, subject to its conditions and heritage exception. Its permit list excepts replacement of existing plumbing fixtures while listing plumbing alterations, structural work and new or altered openings. Confirm uncertain scope with the City. Electrical work may need a separate ESA notification.

| Item | What to know |
|---|---|
| Cosmetic refresh | List tile, paint and fittings without assuming a permit decision covers hidden work. |
| Fixtures stay in place | City’s plumbing item excepts replacing existing fixtures; altered piping is different. |
| Moved plumbing or structure | Check the City’s building-permit requirements before demolition. |
Map what moves
Note whether the toilet, tub, shower or vanity stay in the same location and whether supply, drain or vent piping changes. Identify wall, floor or opening alterations separately. A finish refresh can reveal hidden deterioration that changes the scope.
Include electrical and ventilation
New or changed lighting, receptacles, fan wiring or circuits need an electrical-scope review under ESA’s notification rules. If hiring someone for electrical work, confirm they are an ESA-licensed electrical contractor and will file the notification before work starts. If ventilation is moved or added, record the duct route and any affected assembly, then ask the City about permit requirements for the complete proposed work.
Renovation1 approach
We would compare existing and proposed fixtures, inspect visible moisture damage and identify demolition, trade and approval boundaries before pricing finishes.
What Renovation1 does in practice
Send photos of each wall, the existing fixture locations, proposed layout and any known leak or ventilation issue. Check heritage status with the City before relying on an exemption; hidden damage may change the scope.
