Do other people put shoe racks in the common area? I doubt it.! A common area is not your personal closet. Shoe racks aren’t really that attractive. Yes, you’re paying to use the common area. It’s for sitting, eating, relaxing and socializing, not for storing your stuff.
If the other roommates are storing personal belongings such as clothes in the common area, or leaving dirty dishes around and you’re being singled out, then that’s a different issue and should be addressed directly with them. Maybe you should have a house meeting with everyone together.
