It is illegal for my neighbor to set up a color steel shed behind my house. How can I get him to tear it down?

First: if it is in rural areas, it should be handled by both parties through consultation, because the right to use rural homestead belongs to individuals. But now it is also the construction of new countryside, and the village Committee will also punish this kind of disorderly building. You can make suggestions to the village Committee.

Second: if it is in an urban residential area, it is illegal construction without the approval of the property management department or the relevant departments of the real estate bureau.
