What is the restrictive relationship between developer maintenance and property?

Property companies and developers are generally two independent legal entities, legally speaking, two units.

Maintenance is the developer's commitment to the owner, and the property management company is only the middle coordination department to assist the owner to respond to the problems of the development company and urge improvement. Development companies generally do not leave the balance in property companies.

The question you answer depends on whether you have decorated it yourself. If the circuit changes during the renovation, you have no basis to reflect it before the renovation, and the general development company does not undertake the warranty.

You can go directly to the development company to get the warranty certificate of the commercial house you gave when you handed over the house. If there is a maintenance period on it, press this to find them, and it may be solved.
