If it is a parking space where the owner has obtained property rights, graffiti is not illegal, and graffiti does not violate public security, environmental protection, fire protection and other relevant laws and regulations. And follow the aesthetics of public order and good customs, and do not infringe on the rights and interests of others.
Legal basis: The ownership of the parking spaces and garages planned for parking cars in Article 275 of the Civil Law of People's Republic of China (PRC) shall be agreed upon by the parties through sale, gift or lease.
