Is it a crime for the owner to demolish the property illegally?

Property illegally built in the community cannot be forcibly removed. Property has the right to supervise, but not to enforce the law, so it has no right to dismantle illegal construction, and can only issue rectification notices and exhortations. The realty service enterprise shall stop it and report to the relevant administrative departments in a timely manner. After receiving the report from the realty service enterprise, the relevant administrative department shall stop the illegal act or deal with it according to law.
