Property fees include replacement of unit doors.

Legal analysis: 1. First of all, it is clear that the unit door belongs to public facilities. The cost of overhaul, medium repair and equipment renewal of public facilities is not included in the property fee. Therefore, if it is necessary to replace the unit door, and the unit door is still under warranty, the developer will contact the unit door manufacturer to replace the new door and bear all the expenses. Outside the warranty period, the owner needs to share the update cost. 2. If it is a new building, the owner has paid the special maintenance fund for the house (commonly known as overhaul fund) according to the national regulations when purchasing the house, and the special maintenance fund can be used to pay for the renewal of the unit door.
