[Direct answer]Complaints can be made through multiple departments. Group housing that disturbs the public involves noise, public security, housing safety, and rental order. Complaints can be submitted to the public security organ (for noise disturbance and public security issues), the housing and urban-rural development department (for illegal renting, unauthorized alteration of housing structures, and exceeding the permitted number of occupants), the sub-district office or community (for coordinated handling), or by calling the 12345 citizen service hotline for unified reporting. The Public Security Administration Punishment Law of the People's Republic of China stipulates corresponding penalties for acts of making noise that disturb others' normal lives; regulations such as the Measures for the Administration of Commercial Housing Leasing prohibit the renting of housing that does not meet safety conditions or the unauthorized alteration of housing structures for sub-letting. In Beijing, comprehensive management measures are implemented for illegal group housing, and the 12345 hotline works in conjunction with local departments to handle complaints more efficiently. When making complaints, it is necessary to fix evidence so that the departments can investigate and deal with the cases.

In reality, many people don't know who to complain to, and after filing a complaint, they are often shuffled back and forth between different departments. Some landlords and tenants also believe that this is just a matter of living arrangements and don't consider it a violation of regulations. Only by clarifying the complaint channels and legal basis can we promote the resolution of the problem.
