According to the relevant provisions of the Regulations on Urban Property Management, public maintenance funds are mainly used for the maintenance of all properties and public facilities in the property area, and their ownership belongs to all owners, and their collection and use are also decided by all owners. Therefore, it is illegal for the industry committee to purchase charging piles with public maintenance funds.

Maintenance funds shall be provided by the owners monthly or quarterly in accordance with the standards stipulated by the state, and shall be handed over to the manager entrusted or designated by the owners' committee for safekeeping, and a special maintenance fund account shall be set up for special purposes.
