Section 28-207.2.1. Issuance

Upon  issuance  of  a  stop  work order by the
  commissioner,  all  work  shall  immediately   stop   unless   otherwise
  specified.  Such  order  may require all persons to forthwith vacate the
  premises pursuant to the provisions of section  28-207.4  and  may  also
  require such work to be done as, in the opinion of the commissioner, may
  be  necessary  to  remove any danger therefrom. The police department or
  other law enforcement agency or officer shall, upon the request  of  the
  commissioner,  assist  the department in the enforcement of this section
  28-207.2. The stop work order may be given verbally or in writing to the
  owner, lessee or occupant of the property involved, or to the  agent  of
  any  of  them,  or to the person or persons executing the work. A verbal
  order shall be followed promptly by a written order  and  shall  include
  the reason for the issuance of the stop work order.
