Is it reasonable to collect the public land rent from the property?

You have to open the purchase contract. What does the contract say? Because some developers will indicate in the contract that they will manage the public area on behalf of the owners before selling the house. If you didn't pay attention at that time, there was nothing you could do.

According to the entrustment contract of property management, the property is entrusted by the property user to maintain, repair and rectify the buildings and equipment, municipal public facilities, greening, sanitation, transportation, public security and environmental appearance of the property, and provide comprehensive paid services to the property user and the user.

There is also a property contract. If the contract specifies that a monitor is to be installed, if he can't provide video information, they will be liable for breach of contract. And if they have a parking shed and you want to park in the corridor, they will have no responsibility.
