In the absence of property, owners' committee and overhaul fund, the top floor of residential buildings began to leak, and the collective paid for maintenance, but some did not do it. What should I do? Waterproof warranty for 5 years and pipeline for 2 years. During the warranty period, the developer is not responsible. If not handled, you can complain to the local quality supervision department. They specialize in this matter, and then you can't go to court, or you will be responsible for the delay of the warranty period! In addition, if the same place is not repaired twice during the warranty period, you can find someone to repair it yourself, and the cost will be borne by the developer. The roof of this building is for public use. After the warranty period, minor repairs should be shared upstairs and downstairs. If you can apply for a maintenance fund for an overhaul, it goes without saying that you can't apply, and it is also shared upstairs and downstairs. Go straight to court without paying. It is best to consult the local court directly. It turns out that asking for help is the same, that is, you will win in the end!
