Do you have the responsibility to deal with the cracked property?

If the owner has paid off the large maintenance fund when handing over the house, and the house is naturally damaged, the property service department shall undertake the maintenance. If it is a housing quality problem, the developer should bear the responsibility for maintenance! If there is no responsibility, you can ask for liability for breach of contract.
