In Ottawa finishing a basement requires a building permit where the work involves installation, erection, extension, or material alteration or repair.
That covers most real basement finishes, including framing new rooms. Damp proofing an existing basement is separately exempt, and creating a basement apartment can require a plumbing permit as well.
Designated heritage buildings and properties inside a Heritage District Overlay are not covered by these exemptions, and the City asks owners to confirm with a Building Client Service Centre before starting.

Common questions
Hiring in Stittsville
Stittsville is a growing community on Ottawa's western edge, next to Kanata. It combines an older village core with fast-expanding subdivisions like Fairwinds and Jackson Trails. New builds here drive steady demand for decks, fences, landscaping, and basement finishing, while the older village homes need roofing, windows, and renovation work. The businesses below serve Stittsville and the far west end.
Finishing over a damp basement traps the problem behind new walls. A good contractor checks for water and addresses waterproofing or drainage before framing starts.
A finished basement, and especially a bedroom or secondary suite, needs City of Ottawa permits and code-compliant egress windows. Confirm the contractor handles this; it protects resale and safety.
