Section 28-215.1.1. Lien for emergency work

The  expenses of the city in
  performing emergency work on any structure or  part  of  such  structure
  pursuant  to  this  article shall constitute a debt recoverable from the
  owner and a lien upon the land and any part of such structure  that  was
  not demolished. Every such lien shall have priority over all other liens
  and  encumbrances  on  the  premises  except  for  the lien of taxes and
  assessments. Except as  otherwise  provided  by  rule  of  the  affected
  agency,  the  agency  incurring  such  expenses shall be governed by the
  procedures set forth in article eight of subchapter five of the  housing
  maintenance  code  with respect to the enforcement of such debt and lien
  against all types  of  structures,  including  those  authorized  to  be
  occupied   or   otherwise  occupied  for  residential,  commercial,  and
  manufacturing purposes.
