How to calculate the unit door of real estate replacement

According to the property management regulations, your broken unit door belongs to some owners of the property, not all owners, because other owners have never used your unit door.

Is your unit door shared by the owners of two/kloc-0 units? There are two ways to share, one is to share the housing maintenance fund according to the proportion of the building area of all owners in this unit, and the other is to pay some money by themselves, for example, 20 yuan for repairing the door, which is cost-effective for owners with large housing area.
