Is it allowed to open hotels under commercial and residential buildings in the Property Law?

According to the law, if this behavior has not been voted by the owners, or it is stipulated by the law or management regulations, especially when the developer declares that he has the right to operate and manage other real estate at the beginning of the contract. That's not illegal. However, if you feel that this behavior affects or seriously infringes on your normal life, such as noise, carport, greening, traffic conditions, etc., you can coordinate with the property management Committee, or report it and ask the owners' meeting to vote. If not, according to the adjacent relationship, bring a civil lawsuit.
