Public maintenance fund, also known as public maintenance fund, also known as housing maintenance fund, includes housing public facilities special fund and housing maintenance fund. The public welfare fund is mainly used for the money paid by the owners of the community to repair and maintain the facilities, equipment and public areas in the community.

The public maintenance fund is mainly supervised by the local housing authority and managed by the residential property company. Therefore, the public maintenance fund can only be started when the facilities, equipment or public parts of the community are renovated, updated or overhauled. Therefore, in our daily life, we will not start the public maintenance fund at will, let alone touch it. However, if the owners' committee is established in the community, the management right of the public maintenance fund belongs to the owners' committee, and the public maintenance fund will also be handed over to the owners' committee.
