Case: Xiao Wu, the owner of a residential area, transformed his residence on the first floor into a supermarket for business. Xiao Zhang, a neighbor living on the second floor, thinks that this will cause nuisance to the residents and opposes Xiao Wu's conversion of his house into a supermarket. Xiao Wu, on the other hand, thinks that the house is his own, and he can change it as he wants. Does Xiao Wu's above behavior need to be approved by other owners? This is the case. Article 279 of the Civil Code stipulates that an owner shall not change a residence into a business house in violation of laws, regulations and management regulations. If the owner changes the residence into a business house, in addition to abiding by laws, regulations and management regulations, it shall obtain the unanimous consent of the interested owners.
