Is it illegal to dismantle doors and windows privately?

It is illegal to remove the owner's doors and windows (including illegal buildings).

The property is only entrusted by the owner to manage the houses and other ancillary facilities in the residential area. The property itself is not an administrative organ, nor is it an entrusted institution, and it has no right to forcibly dismantle illegal acts in the community. Otherwise, it is an illegal act and should bear tort liability according to law.

For illegal buildings, the property should be reported to the urban construction department, which will organize the demolition.
