Who should be responsible for the maintenance of the hardcover house purchased by the owner?

Hello, if it is still under maintenance, you can find a developer or a property. In March this year 15, the new Consumer Protection Law came into effect. For finely decorated commercial housing, the "new elimination method" has broken through the bottleneck of consumers' difficulty in providing evidence in the past, and changed the burden of proof for housing quality problems to operators. In other words, if the housing enterprises think that the quality problems of finely decorated houses are caused by improper use by consumers, then the housing enterprises should provide corresponding evidence to prove them. The New Consumer Law stipulates that "if a consumer has defects within six months from the date of accepting a commodity or service, and a dispute occurs, the operator shall bear the burden of proof for the defects", which is beneficial for the buyer to find out whether there are quality problems in the concealed works.

Hope to adopt, thank you!
