Public maintenance fund invoices are issued by the Housing Authority. Generally, the developer gives the public maintenance fund to the Housing Authority, and then the Housing Authority issues an invoice.

Public maintenance funds will not issue invoices to individuals, but will issue special maintenance fund receipts. The public maintenance fund is a special maintenance fund collected and managed by the real estate management department, which belongs to all owners and does not need to pay taxes, so no invoices are issued. The use of public maintenance funds shall be signed by the owners' committee and the owners, and paid by the real estate management department.
