What should I do if the property is installed with ladder control without the consent of the owner?

If the owner's rights and interests are infringed by the property, he may complain to the local real estate administrative department or the Housing Authority. After receiving a complaint, the local real estate administrative department or the housing management department should actively negotiate and deal with it, try to solve the problems related to the complaint as much as possible, and provide a good living environment for the owners. Legal basis: Article 47 of the Property Management Regulations stipulates that the rights and obligations of property users in property management activities shall be agreed by the owners and property users, but they shall not violate the relevant provisions of laws, regulations and management regulations. If the property user violates the provisions of these regulations and the management agreement, the relevant owners shall bear joint and several liability. Forty-eighth real estate administrative departments of local people's governments at or above the county level shall promptly handle complaints from owners, owners' committees, property users and property service enterprises in property management activities.
