Legal analysis: the developer is only responsible for collecting the maintenance fund, and the final invoice is still the responsibility of the Housing Authority. In the future, the use and withdrawal of the maintenance fund will still be supervised by the Housing Authority. Service conditions of maintenance fund: 1. The maintenance fund can only be used for the overhaul, renewal and transformation of public parts and facilities of the property after the warranty period expires. The specific owners shall share the cost proportion according to the standard for determining voting rights. 2. When the maintenance fund is idle, it is forbidden to use it for other purposes except for purchasing government bonds or other funds as stipulated by laws and regulations. 3. Unless otherwise agreed in the property management service contract. (2) If the house needs to be overhauled or specially repaired or updated, the advance payment agreed in the construction contract may be withdrawn, but the advance payment shall not exceed 30% of the total project amount. (three) the owners' committee may keep a reserve fund equivalent to one month's activity funds in the account of the property management enterprise, unless otherwise decided by the owners' meeting.

Legal basis: Article 28 1 of the Civil Code, the maintenance fund of the building and its ancillary facilities belongs to the owner. With the consent of the owner, it can be used for local maintenance, renewal and transformation of elevators, roofs, external walls and barrier-free facilities. The collection and use of maintenance funds for buildings and their ancillary facilities shall be announced regularly. In case of emergency, if the building and its ancillary facilities need to be repaired, the owners' assembly or the owners' committee may apply for the maintenance funds of the building and its ancillary facilities according to law.
