The ceiling falls off and the property is perfunctory.

First of all, find the property related department to solve it, if they don't accept the solution.

Then, you can find a small district Committee to handle it, if they still don't handle it.

Finally, it can only be solved through legal procedures. When you make up your mind to go through legal procedures, all you need to do is firmly apply for the relevant house (pay for it yourself, and finally add it to the compensation fee at one time). Now you need to hire a lawyer.
