Is it necessary for all owners to agree to change the property fee contract?

If the owners' congress has been established in the community, the property service charges will be subject to market adjustment, and the owners' congress and the property company will negotiate their own charging standards; If the preliminary realty service contract expires but the owners' meeting is not established, it must be agreed by more than half of the owners, and the realty service enterprise and the owners shall re-agree within the published guidance price. During the performance of this contract, due to major changes in policy factors or service items and contents, the property service fee has undergone major changes. If it is necessary to adjust the charging standard, the realty service enterprise shall publicize the change of the realty service fee in a prominent position in the realty management area, and obtain the consent of the owners (double and half owners) who account for more than half of the total construction area and more than half of the total number.
