In Saint-Léonard, the borough’s permit counter receives applications, and several can be filed online: roofs, doors and windows, exterior stairs, exterior cladding, balconies and galleries. Changing the façade of a single-family house or a multiplex is subject to PIIA (site planning and architectural integration) review, except for replacing a window, a door or a balcony and its stairs, and in the COOP sector any change to the exterior appearance is subject to it. According to the City, lead water service lines are very unlikely in Saint-Léonard.
