Is it illegal to build a roof wall?

The rooftop is connected with the neighbor's rooftop, and there is no partition wall. You built a two-meter fence on one side to separate it. There is no doubt that your practice is illegal. If you are reported, you will be severely punished by law.

Urban Management Brigade: It is illegal to build any building on the rooftop without authorization, which not only affects the cleanliness and beauty of the whole community, but also destroys the bearing standard of the building and becomes a safety hazard of the whole building. If the owner encounters water leakage in the house, he should find a developer or residential property to solve it. Users should never build a building without permission to solve the problem of water leakage in the house.
