Stop-work orders; notice.

Whenever the Building Inspector has reasonable grounds to believe that work on any building or structure is being prosecuted in violation of the provisions of the applicable building laws, ordinances or regulations or not in conformity with the provisions of an application or plans on the basis of which a building permit was issued or in an unsafe and dangerous manner, he shall notify the owner of the property or the owner's agent or the person performing the work to suspend all work, and any persons shall forthwith stop such work and suspend all building activities until the stop order has been rescinded.

Such order and notice shall be in writing, shall state the conditions under which the work may be resumed and may be served upon a person to whom it is directed either by delivering it personally to him or by posting the same upon a conspicuous portion of the building under construction and sending a copy of the same by regular mail to the address designated in the building permit or the property owner.
