Is it illegal for owners to ask for price increases without charging property fees?

It is illegal for property owners to ask for a price increase. According to the "Property Service Management Inquiry Regulations", the property service enterprise must issue a written notice to all owners and obtain their consent before implementing the price increase plan. Property service enterprises raise prices without consultation, or fail to issue a written notice to a single owner, which is regarded as violation. The realty service enterprise shall, according to the service fee stipulated in the realty service contract, inform the owners' assembly or owners' committee in writing fifteen days in advance, explaining the service content, service standards and service charging standards. If it involves the change of service fee, it is necessary to seek the consent of the owners' meeting or the owners' Committee.
