Is there a legal basis for the property to prevent the owner's car from entering the community?

The property has no right to stop the owner from driving into the community. Because the land ownership of parking spaces in the community belongs to all owners, the property company has no ownership of parking spaces, only management rights, and cannot control, occupy or dispose of parking spaces, so the property has no right to prevent owners from driving into the community.

Legal objectivity:

Article 275 of the Civil Code stipulates that the ownership of parking spaces and garages planned for parking cars shall be agreed upon by the parties through sale, gift or lease. Parking spaces that occupy roads or other venues owned by the owner for parking cars shall be owned by the owner. Article 276 Parking spaces and garages planned for parking cars within a building division shall first meet the needs of the owners.
