Many city residents are not satisfied with their property management service providers.
Shanghai Consumer Rights Protection Commission said a survey revealed that unreasonable charges and poor service drew the most complaints.
Respondents also felt angry over property management companies' inability to prevent group renting, decoration noise and pet disturbance, as well as their slow response to complaints, such as safety issues and repair demands, the survey found.
The survey, which was carried out with Shanghai Academy of Social Sciences, questioned 2,000 people.
About 29 percent of respondents said property management companies' charges were unreasonable, and 26.5 percent said the charges were not transparent.
More than 25 percent believed property management companies did not provide enough services, while 24 percent complained about parking spaces being rented to outsiders.
Other complaints concerned advertisements in elevators and thefts.
More than 3 percent of interviewees said they never paid property management fees, while 20 percent said whether they would pay the fees depended on their mood.
The commission urged property management companies to make all charges transparent and trial a basic property management fee structure along with an extra service fees model.
