View Ottawa General Contractors (OGC)Before you hire in Gloucester
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 Gloucester
Gloucester is a broad east-end area of Ottawa spanning established neighbourhoods and industrial-adjacent pockets between the downtown core and Orléans. Its mix of older homes and postwar builds means roofing, eavestroughs, window and door replacement, driveways, and basement work are all common. The service businesses below serve Gloucester and Ottawa's east 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.
