Heat pumps in Saint-Michel: permits and bylaws
Planning a heat pump or an air conditioner in Saint-Michel? Here is what the bylaws say: the permit, the distance from the lot lines, where the unit can go and the noise limit. It all comes from the official texts.
Five spots, one answer for each.
Each answer is the bylaw rule, in short. “Not specified” means the text does not say: ask urban planning.
