What department should I find to manage the toilet if the toilet is affected by the unauthorized alt

If the toilet is changed without permission and affects the neighbors, the neighbors can go to your local neighborhood committee to complain, because the toilet renovation in the village is organized by the village committee, so you can find them if something happens.

I don't know if you are in the countryside or in the city, if you are rural, you should ask the people in the village to help you talk about it, and you can find a middleman who knows you and him, but you have to solve the problem.

You can find the property in the community, and the homeowner to negotiate and communicate.

You can find community properties and neighborhood committees.

Changing the toilet without permission affects the neighbors to go to the property under normal circumstances, report the situation to the property, and let the property help you deal with the problem for a while.

If the change to the toilet affects the neighbors, you should be able to find the property department and give your opinion in May this month.
