Who is responsible for the maintenance of the tiles falling off the external wall of the community?

1. If the house has just been delivered, the developer is responsible for the maintenance. At present, commercial housing has a warranty period, usually five years. If the external wall falls off during the warranty period, that is, there is a problem with the quality of the building, you can ask the developer to carry out maintenance. 2. If the warranty period expires, the property management company will carry out maintenance. After the warranty period, the developer has no responsibility, because every owner needs to pay the maintenance fund to the property, so in this case, the maintenance fund of the property can be started.
