How to divide the rights of elevator users and owners?

The owner's rights depend on who owns the real right, such as renting an office building. The elevator is a facility in the office building and belongs to the owner of the office building. Office buildings can be rented to units and managed by property. The unit is the user and the property is the manager. The right to use the owner and the user is generally stipulated in the contract. In the words of community owners, all owners have the ownership and use right of elevators.
