Projects Not Requiring Building Permits in Ottawa
From the City of Ottawa website on 2020.March.10 You may also want to visit the more detailed Do I need a building permit? page on that site.
A detached accessory structure (gazebo, tool shed, etc.) that measures less than 10 square metres (approx.108 square feet) does not require a building permit.
Designated Heritage Buildings or buildings located within a Heritage District Overlay are not subject to exemptions and require that you contact a Building Client Service Centre representative for specific information.
The following is a list of projects that are exempt from having to obtain a permit:
- Installing asphalt shingles on a roof
- Damp proofing of existing basements
- Replacing doors or windows (provided they are in the same size opening)
- Replacing kitchen or bathroom cabinets (provided plumbing fixtures remain in same location)
- New flooring

- Replacing an existing hot water tank
- Fences (not enclosing a pool – see Pool Enclosure By-law 2013-39)
- Pool heaters
- Painting and decorating
- Deck less than 24 inches above grade, except main entrance
If you are unsure that the scope of your project does not require a building permit please contact Building Code Client Service Centre or 3-1-1 for more information. You can also e-mail firstname.lastname@example.org
