Whenever the Code Enforcement Officer has reason
to believe that the work on any building or structure is being performed
in violation of the provisions of the applicable building laws, ordinances,
rules or regulations, or not in conformity with the provisions of
an application, or in an unsafe and dangerous manner, the Code Enforcement
Officer shall notify the owner of the property, or the owner's agent,
to suspend all work and suspend all building activities until the
stop-work order has been rescinded. Such order and notice shall appear
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 where the work is being performed
and sending a copy of the same to him by certified mail.
