Residential buildings are generally not allowed to be used to open beauty salons.
However, if the local laws do not explicitly prohibit opening a shop in a residential building, you can go through the corresponding procedures according to law and get the consent of more than half of the residents in the building, so you can open a shop smoothly.
Article 279 of the Civil Code stipulates that the owner shall not change the house into a business house in violation of laws, regulations and management regulations. If the owner changes the house into a business house, in addition to complying with laws, regulations and management regulations, it shall also be unanimously agreed by the interested owners.
