Overhaul fund, also known as the maintenance fund, each region has its own terms on the scope of use of the maintenance fund, but it is based on the detailed terms of the Measures for the Administration of Residential Special Maintenance Fund issued by the Ministry of Construction and the Ministry of Finance in February 2008. Overhaul fund is mainly used in two aspects: First, it is used for overhaul, renewal and transformation of houses and buildings with * * * assets or * * * facilities and equipment after the warranty period expires. Such as elevators, secondary water supply, central air conditioning, various pipelines, post offices, garbage lanes, fire-fighting facilities, etc. Second, it is used for the maintenance of * * * parts, that is, the load-bearing structural parts of houses, including floors, roofs, beams, columns, internal and external walls, stairs, corridors, etc. The premise is that these problems occur at the * * * site rather than the owner's home. For example, problems such as water leakage and ceiling collapse in the owner's home do not belong to this category, so overhaul fund cannot be used. After the first maintenance is completed, overhaul fund will be directly deducted from the respective accounts of the owners according to the housing area or cost sharing after calculation and verification by the District Housing Management Bureau.
