First, it depends on the purpose of the house registered on the property right certificate. If it is a residential building, it may not be used for commercial purposes, and it is impossible to start a company. If it is a business room or a mixed room, it is still possible. Houses between different uses can be changed (house use), and the local housing and land management department is responsible for it. If it is clearly a residential building, under normal circumstances, the industry and commerce will not register it, so the ninth floor of your home may be undocumented and you can report it to the industry and commerce. Other channels, such as complaining to property management companies and housing management departments, and asking for help from the media are also good methods. Of course, you have to find out the nature of the company first.
Second, neither the owner nor the user can change the nature of the use of residential houses at will, nor can the residential houses do business. If the nature of the use of residential houses is to be changed, it needs the consent of interested owners. That is, it can be started, but it must be approved by the interested owner and obtain relevant permission.
3. When handling the business license, the industrial and commercial departments should review the business premises. If the purpose of the room written in the rental agreement is "residence", it is not a commercial house and does not meet the conditions for obtaining a permit.
Fourth, residents on the first floor who open their own stores at home must go through the relevant formalities and put them on record. Generally, this situation is illegal, because the nature of the house has been changed by the owner, and basically many formats cannot go through legal procedures.
Legal basis:
Article 77 of the Civil Code
Owners shall not violate laws, regulations and management regulations, and change the house into a business house. Owners who change their houses into business houses shall obtain the consent of interested owners in addition to observing laws, regulations and management regulations.
