Is it legal to ask the decoration company to decorate the property?

It is illegal, as long as the decoration does not change the main structure of the house and does not destroy the load-bearing wall. Does not affect the overall image of the community (that is, installation of anti-theft facilities, sun room, air conditioning outside the machine). Do not change the water pipe circuit outside the house, and do not affect the normal rest of neighbors. The property management company has the right to supervise your renovation process. As for how you pretend, whoever pretends has no right to interfere.
