Renovation permits in L’Assomption

According to the City of L’Assomption, any project to build, enlarge, renovate or alter a building needs a building permit. Work on an existing building whose cost (labour and materials) is $3,000 or less before taxes does not need one, as long as it does not affect the foundations, the structure or the interior partitions, does not increase the floor area, does not affect any fire-protection element, and does not involve adding or closing off a window or replacing the exterior cladding. Some sectors and types of work are subject to a PIIA (architectural integration plan), authorized by city council after a recommendation from the planning advisory committee.
