Heat pumps in Verdun: permits and bylaws
Planning a heat pump or an air conditioner in Verdun? 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.
At least 1 m from every lot line.
At least 1 m. On a side wall: 2 m from the front wall.
At least 1 m from the lot line and 3 m from the sidewalk or curb, hidden by evergreen plants or a screen as high as the unit.
No higher than the railing, 1 m from the lot lines; on the façade, only for 13 dwellings or more.
Flat roof only. Within 3 m of a wall facing a street: metal screen of the same height, set back from the façade by twice its height.
Good to know, and who to call.
