Is it reasonable for the property to charge the owner for garage electricity in advance?

It's a simple thing. The fundamental problem of this problem is that the relationship with the owner is unclear. The normal situation should be: the owners' committee is the representative of all owners, and the owners' committee and the property management company have a contractual relationship. If the rights and obligations of the property management company are not clearly defined in the contract, then the rights he exercises need the consent of more than half of the owners, otherwise he is illegal.
