Which department should I complain to if there are quality problems in the new house I bought?

If you find quality problems, first look for developers, because property buyers and developers have a direct contractual relationship. Developers, as producers and sellers of commercial housing, bear the ultimate responsibility for the quality of commercial housing. The quality relationship between the developer and the buyer is bound by the commercial housing sales contract and the commercial housing quality guarantee. If the buyer demands compensation for the losses caused by quality problems, the developer shall compensate the buyer, and then the developer shall recover from the responsible unit according to the quality reasons and the contract.

(2) If there is a dispute over the quality warranty responsibility of commercial housing, and the developer refuses to solve it, or is dissatisfied with the developer's solution, the parties may apply to the construction engineering quality supervision institution for organization appraisal or complain to the construction administrative department. For problems that affect the structural safety of houses, residents can directly entrust units with statutory structural safety appraisal qualifications to appraise houses, and the appraisal conclusion can be used as evidence of civil compensation.

(three) to bring an arbitration or bring a lawsuit to the people's court according to law. If the above channels cannot be solved, the buyers can sue the developers according to the law and their actual situation.

To sum up, we can easily find that the housing quality problem has become a common phenomenon. Many residents don't know how to complain about similar housing problems and how to solve them. They often look for property as soon as there is a problem, and the property department gives the problem to other departments because it is unable to solve it or for other reasons, which makes the problem drag on. I would like to remind property buyers to negotiate with the developers first, find out the nature of the problem, and then choose different ways to deal with it. If necessary, you can ask a lawyer to help you solve it and better safeguard your rights and interests.
