Renovation permits in Sainte-Thérèse
According to the City of Sainte-Thérèse, exterior or interior renovation needs a permit, unless the work is worth less than $20,000 (labour included) and does not affect the structure or the partitions. Outside, it must also not affect the foundations, increase the building’s footprint, change its height, add or remove an opening or replace the exterior wall cladding; inside, it must not affect safety features (firewall, fire protection), and the cumulative total of all the work counts. Replacing a roof covering with an identical material or replacing windows without changing their size does not need a permit, except in the PIIA sectors (the Village, the Gare and boulevard du Curé-Labelle), where a permit is required whatever the work. Moving a wall or changing the foundations or the structure needs a permit. You apply online.
