Commercial real estate has a maintenance fund. According to Article 12 of the Measures for the Administration of Residential Special Maintenance Funds, the owners of commercial housing should deposit the first phase of residential special maintenance funds into the special account of residential special maintenance funds before going through the formalities of housing occupancy. The owner of the sold public housing shall deposit the first special maintenance fund of public housing into the special maintenance fund account of public housing or hand it over to the selling unit for deposit into the special maintenance fund account of public housing before going through the housing check-in formalities. Maintenance fund, also known as public maintenance fund and special maintenance fund, specifically refers to the fund that the owners of residential properties pay a certain standard of money to a special account for the maintenance of public parts and facilities and equipment in the property area, and authorize the owners' committee to manage and use it uniformly. The maintenance fund is raised by the owners of the property, who enjoy the ownership of the maintenance fund according to the proportion of payment, but the right to use it belongs to all owners, and individual owners may not withdraw all their own maintenance funds from the bank.
