Which department should I look for if the house leaks?

First, housing leakage is a housing quality problem, which should be borne by developers.

Second, developers and property management companies are two main bodies, and owners and developers and property management companies are two different legal relationships. The relationship between the owner and the developer is a sales contract, and the relationship between the owner and the property management company is an entrustment contract. Some property companies are subsidiaries of developers, and some property companies and legal representatives of developers are the same person, but it does not mean that developers are property companies.

3. If the owner encounters water leakage in the house and repeatedly looks for property maintenance but fails to solve the problem, the owner should sue the developer instead of the property company, but he can inform the property company in advance to check and cooperate with the investigation of the cause of water leakage.
