Renovation Costs in Gatineau

Average renovation costs and estimates for Gatineau, Quebec.

Updated July 28, 2026

Gatineau is priced with Ottawa in the next breath: many contractors serve both sides of the river, but a job in Gatineau carries GST + QST rather than HST and requires an RBQ licence. The housing runs from older homes in Hull and Aylmer to newer developments in the Plateau and Buckingham; on our cost index Gatineau sits below Ottawa.

📋 Permits & Regulations

Under $26,000 of work on an existing building, Gatineau generally asks no permit unless the foundation, the structure or interior walls are involved; above that a building permit applies. The URBAIN assistant on gatineau.ca answers for your address, and the city commits to no processing time. The Hull sector's heritage areas add a review for visible changes.

🌡️ Climate Impact

Gatineau gets Ottawa's cold winters and heavy snow, and more snow toward the Gatineau Hills. Spring flooding from the Ottawa and Gatineau rivers has been severe in recent years, which is why the city requires every home to have a backwater valve and why flood-zone awareness comes first in a basement project.
