When the emergency maintenance funds exceed 500,000 yuan, according to the relevant regulations, this part of the funds should be mainly used for public parts and parts that need maintenance. Public parts include public areas of buildings, such as hallways, corridors and stairs, as well as public facilities, such as elevators, water supply systems and power supply systems. The parts that need maintenance refer to areas with problems or potential problems, such as water leakage, broken walls, damaged equipment, etc. This treatment can ensure the rational use of funds and maintain the normal operation of public facilities and the living environment of residents.
