Can residents in the community use the elevator when installing the elevator?

You can't use the elevator installed by the residents.

The elevators installed by residents in the community are designed for their own use, and the property management company has no right to use the elevators. The installation and use of the elevator is the responsibility of the residents themselves, which has nothing to do with the management responsibility of the property management company. The responsibility of the property management company is mainly to manage the public areas and facilities of the community, excluding the right to use private equipment of residents.
