Which department is responsible for property decoration management? Or a separate department is responsible.

The internal regulations of each property management company are different, some are in charge of the engineering department, some are in charge of the security department, and some properties have special "on-site management" departments. The key is that as long as someone is in charge, whether it is security or other management personnel, everyone is in charge. What department management is an internal problem of their enterprise, and the owners have no right to interfere.
