Is it the owner's money or the property that changes the unit door?

According to the Property Law of People's Republic of China (PRC), the unit replacement door belongs to the exclusive part of the owner, who is responsible for maintenance and replacement. Moreover, according to the Regulations on Property Management in People's Republic of China (PRC), the property management company is responsible for the maintenance and management of public facilities in the community, and the replacement of doors belongs to the owner's private property and does not belong to the category of public facilities. Therefore, the maintenance and replacement cost of replacing the unit door should be borne by the owner.
