The upstairs is leaking, the furniture and decoration are broken, and my downstairs is miserable. What should I do? Who is responsible for the compensation?

The loss of you and your downstairs should be the compensation of your upstairs, but there is a question, where did it leak? If it is a large area of water leakage, it has a lot to do with the quality of the house. First, coordinate the compensation of property companies. If it is a small area of water leakage (the kitchen and bathroom belong to the waterproof quality problem of the construction party), it is necessary to coordinate compensation with the upstairs and let him find the construction party for compensation.

You are not responsible for the fault. The cause of the matter is not you, but your upstairs. He has the fault responsibility (forgetting to turn off the tap, etc.), and the developer has the quality responsibility. Now you should know who to call, right? The developer and you will pay for it all upstairs.
