Which department should I look for if the house leaks?

If the warranty period of the house exceeds 5 years, or the waterproof house made by the developer is not made, or the waterproof house made by the developer is damaged in the renovation process, or the home leaks due to man-made damage, the property may not bear any responsibility. If the water leakage at home is not caused by the above matters, go to the property department of the local housing authority to complain about the inaction of the property. Go to court to sue the property for inaction and let the property bear the responsibility for the loss of water leakage at home. The water pipe upstairs leaks, so the dead upstairs won't stay. First of all, you should ask the quality inspection department of the house to make an appraisal report on the causes of water leakage in the house and how to make up for it. If it is identified as the fault of the neighboring party, the neighboring party may be required to repair it immediately or in time according to the report, and may be required to compensate for the damage caused during the repair period. If the neighboring parties do not cooperate, the injured party may submit the dispute to the court.

Legal basis:

Article 288 of the Civil Code of People's Republic of China (PRC) * * * The neighboring owners of real estate shall correctly handle the neighboring relations according to the principles of favorable production, convenient life, solidarity and mutual assistance, and fairness and reasonableness.
