I finally checked in happily, but I have a new problem: how is the service of the property? How to use the public maintenance fund and other issues. In this issue, I will introduce some knowledge of the public maintenance fund. 1. How many years is the maintenance fund valid? There is no time limit for the maintenance fund. No matter whether it is not used or used up, it will always exist in the personal ledger; If the house needs to be relocated during the use period, the balance in the owner's household professional fund account will be returned to the owner in proportion. Second, what is the maintenance fund 1. After several changes, the name of the housing maintenance fund was changed to the residential special maintenance fund in 27. According to the regulations, the single-account accounting of special funds can only be used for the public parts of the community, the renovation of public facilities and equipment in the community and other projects, and it is not allowed to be used for other purposes. 2. Under the principle of "money goes with the house", when the owner transfers the house, the balance of the house maintenance fund will be transferred to the new property owner. 3. If the balance of the maintenance funds paid in advance by the owner's household accounts is less than 3% of the first deposit amount, it should be handled in time, and the renewal plan can be decided by the owners' meeting. 3. Under what circumstances can the housing maintenance fund be used? It must be voted by the industry committee, and two-thirds of the owners of the residential area and more than two-thirds of the total number of owners jointly agree, so that the property can use the fund to transform the main body, public parts or public settings of the house. 1. Main load-bearing structure: maintenance of foundation, load-bearing walls, columns, beams, floors and roofs inside and outside the building; 2. Public parts: maintenance of public halls and passages, outdoor walls of houses, staircases, etc. 3. Public facilities and equipment: maintenance of water pipes, wires, elevators, fire protection, greening, roads, drainage, parking garage owned by the owner, public welfare cultural and sports facilities, etc. in the supporting area.
