Your car is parked more than driven. When there is prolonged period when vehicle is not used, rust would form on the the brake rotors no matter where you park it.
Moisture from the atmosphere would cause it and there is nothing you can do to prevent it except keep the rotors warm.
Front are ok and rear is not might be due to quality of parts used.
