The property fee has been paid, and there is something wrong with your door frame. Is there an obligation to maintain the property?

No obligation. Somebody else's maintenance man went to talk about it. I've been entertaining him for half a day. There is a seal on the door frame that needs to be blocked with glass glue. You can buy anything you need. The repairman of the property is here to repair the public parts. The entrance door of your house is the corridor door of your own house, and the safety access door is managed by others.
