Which department should I complain to the developer about the leakage of the new house?

1. The newly bought house is leaking, so you should usually look for the property department first. Because the property department is generally entrusted by the developer to contact the maintenance affairs, the property department (entrusted by the developer) will contact the construction unit for warranty. The developer has a contract with the construction unit, and the developer deducts the warranty money from the construction unit. Therefore, as long as it is not due to abnormal use, the construction unit must ensure that "the house leaks and it rains all night".

2. Because you only have a contract and warranty relationship with the developer, you can directly find the developer (or the representative of the property department or construction unit entrusted by the developer).

You are protected by the terms of the contract and the consumer rights law. Property departments and developers, no matter you can complain. Complaints should be made to the local "Construction Engineering Quality Supervision Station" or the local "Consumers Association".

4. At the end of the warranty period, you can find the property department for maintenance. If it's not for you, you don't have to pay it (from the housing maintenance fund, it's already paid by the buyers and developers).
