Can a property company unilaterally increase the property service fee?

Legal analysis: If a property company wants to increase the property fee, it should obtain the consent of the owners' committee of the community, or hold a document issued by the price department to adjust the property fee and other legal basis. Increasing the property fee without authorization is an act of unilaterally changing the contract. Changes to the contract must be agreed by both parties through consultation, and unilateral changes are invalid.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 543 The parties may modify the contract through consultation.

Article 544 Where the parties have not expressly agreed on the contents of the contract modification, it is presumed that the contract has not been modified.
