In Salaberry-de-Valleyfield, a building permit is required to build, alter or enlarge a building, and a certificate of authorization to renovate. Minor maintenance work does not need one, as long as the foundations, the frame and the structures are not changed: a roof redone with the same type of covering, painting, mortar joints, doors and windows of the same size, repairs to a porch or balcony without enlarging it, and interior renovations that touch neither the fire separations nor the layout of the rooms (flooring, cabinets, electrical, plumbing, except in the basement). Applications are made entirely online.
