Renovation permits in Montréal
In Montréal, permits are issued by the permit counter of each borough, online or in person. According to the City, a permit is required for work that affects the walls or foundations of a dwelling, or that changes the size, layout or use of a room. Some minor cosmetic work does not need one: flooring, painting, cabinets, countertops, a sink or a bathtub. The City no longer issues permits for plumbing, electrical and heating work: that work follows provincial rules and is done by licensed contractors.
