Does the property have the right to ask the owner for money for non-load-bearing walls and doors? Does the country have relevant policies and regulations?

First of all, the property is not a law enforcement department. Even if it is illegal decoration, his power is limited to inform, stop, report and other powers. He has no right to collect fees such as the owner's deposit. Since the deposit is to be refunded, the property has no administrative law enforcement power to punish the owner or deduct the owner's money.

Non-load-bearing walls can be completely dismantled and doors can be installed. If the property uses this as an excuse to deduct the decoration deposit, it only needs 1 phone number, and the price bureau's toll reporting phone number will be fine. Leave only the decoration deposit.
