Can the property management house be shared as a public building?

Can the property management house be shared as a public building? 1. Property management rooms generally include property offices, personnel on duty and rooms for storing tools and materials. Property management houses should be houses designed for property management, office or residence. 2. Property management houses serving multiple houses can be shared by multiple houses. 3. The shared property management area of each commercial house can account for about four thousandths of the construction area of the commercial house, but the maximum amount shall not exceed six thousandths. Calculated by six thousandths, if all the apportioned property management houses are less than the construction area of one house or a set of houses, it shall be confirmed according to the minimum construction area of one house or a set of houses designed by the commercial house. In the commercial housing sales contract, if the buyer and the seller have otherwise agreed on the shared property management room, such agreement shall prevail.
