Before an outdoor unit goes in
Saint-Laurent requires no permit for a heat pump or air conditioner on an exclusively residential building. A permit (524 $ per unit, valid 6 months) applies when the equipment is outside a commercial, industrial or institutional building, and installation must follow the zoning bylaw. Check the permit with the borough before installation; we size and place the unit to meet it.
