Is there an obligation to solve the leaking property upstairs?

If there are relevant clauses in the property contract, the property is obliged to solve them. The property shall provide corresponding services in accordance with the provisions of the property contract, and the owners shall be responsible for those not stipulated in the contract, but the property can provide paid maintenance.

Legal objectivity:

"Regulations on Property Management" Article 35 A property service enterprise shall provide corresponding services in accordance with the provisions of the property service contract. The realty service enterprise fails to perform the realty service contract, causing personal and property safety damage to the owner, and shall bear corresponding legal responsibilities according to law.
