Can I put up an advertisement or something in the elevator?

Residential elevators, as the * * * parts and * * * facilities of the property legally enjoyed by the owners, enjoy the ownership or use right according to law. Therefore, as long as the area shared by the community owners is used for advertising, whether in the elevator or in other * * * use parts, the advertising revenue should naturally be enjoyed by the owners. If losses are caused to the owners, they shall be liable for compensation according to law.

Legal basis: Article 54 of the Regulations on Property Management, if a property uses * * * parts and * * * facilities and equipment for business operation, it shall go through relevant procedures in accordance with regulations after obtaining the consent of relevant owners, owners' congress and property service enterprises. Owners' income should be mainly used to supplement special maintenance funds, and can also be used according to the decision of the owners' congress.

According to Article 57 of the Regulations on Property Management, if the construction unit arbitrarily disposes of the ownership or use right of the property parts and facilities belonging to the owners in violation of the regulations, the real estate administrative department of the local people's government at or above the county level shall impose a fine of more than 50,000 yuan but less than 200,000 yuan; If losses are caused to the owners, they shall be liable for compensation according to law.
