Heat pumps in Mirabel: permits and bylaws
Planning a heat pump or an air conditioner in Mirabel? 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.
2 m from the lot lines (1 m with a sound-absorbing screen), hidden from the street and the neighbouring lot.
Only alongside the rear half of the house, 2 m from the lot lines (1 m with a sound-absorbing screen).
Only under a concrete balcony, not visible from the street.
Ductless (wall-mounted) heat pump: allowed on a front balcony, 1 m from the lot lines.
Not specified in the bylaw: confirm with urban planning.
