Three months after the delivery of the house, serious blisters were found, which affected the occupancy. Who will pay the property fee, and the legal basis?

Property responsibility. Article 53 of the Regulations on Property Management stipulates that the owners of residential properties, non-residential properties in residential quarters or non-residential properties connected with a single residential building structure shall pay special maintenance funds in accordance with the relevant provisions of the state. If serious flooding problems are found three months after delivery, which affects occupancy, the property shall bear the responsibility, and if the owners' rights and interests are damaged, they may require the property and developers to bear the relevant responsibilities. Specific analysis of specific problems involves the intervention and assistance of entrusted lawyers.
