Renovation permits in Mont-Saint-Hilaire
According to the City of Mont-Saint-Hilaire, construction, demolition or renovation are among the work that needs a permit or a certificate of authorization. Under its by-law, renovating a building needs a certificate of authorization, including replacing a balcony, gallery or chimney, and replacing doors and windows without changing their size; changing that size or adding such an element is a transformation, which needs a building permit. Before applying, check whether approval of a PIIA (architectural integration plan) is needed. You can apply online, and the permit or certificate must be posted where it can be seen. Even if the contractor obtains the permit on the owner’s behalf, the owner remains solely responsible for the project.
