Is the notice of illegal construction and demolition issued by the property useful?

Of course it works. It can be proved that the property has been notified to you. If there is danger or loss, the property can be irresponsible in the future. The responsibility lies entirely with you.

In addition, real estate can also be used as proof. If you still don't rectify it several times, the property can sue you. This notice is proof.

The public area is illegal, which violates the occupancy agreement signed by you and infringes on the interests of others. It should be demolished.
