How to notify the illegal building when the external wall tiles fall off and break?

XX, XXX room, XXX owner!

Your household illegally built a house on the top floor without the approval of the planning department. The District Housing and Construction Bureau, the District Demolition Office and the property company have repeatedly come to the door to persuade them to be invalid. We hereby issue a notice to dismantle illegal buildings and order your households to dismantle them themselves within one week.
