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.

Lead water service lines in Montréal

In Montréal, replacing the private part of the water service line is mandatory if it is lead (By-law 20-030). The owner must replace it within 24 months of the City’s notice of non-compliance, or can do it earlier with a contractor of their choice after contacting the borough’s permit counter. After the work, the owner declares the material to the City with the invoice and photos.
