A. The director of licenses and inspections or director of health may condemn as unfit for human habitation any housing or housing unit he or she may deem to be so damaged, decayed, dilapidated, insanitary, unsafe, or vermin-infested that it creates a serious hazard to the health or safety of the occupants or the public.
B. Any housing or housing unit condemned as unfit for human habitation and so designated and placarded shall be vacated within a reasonable time as ordered by the enforcing officer, and occupants shall be vacated in accordance with applicable relocation provisions in 18-110 .
C. No housing or housing unit which has been condemned and placarded as unfit for human habitation shall again be used for human habitation until written approval is secured from, and such placard is removed by, the condemning authority.
D. The condemning authority shall remove such placard whenever the defect upon which the condemnation and placarding action was based has been eliminated.
E. No person shall deface or remove the placard from any housing or housing unit which has been condemned as unfit for human habitation and placarded as such, except as provided in paragraph D.
F. Where no corrective action is taken by the owner, operator, or occupant of a housing or housing unit designated as unfit for human occupancy within six (6) months following the date of the placarding action and when no hearing is pending, the director of licenses and inspections shall seek judicial remedies and may consider pursuing an order that the structure in violation to be demolished as soon as practicable, provided that reasonable notice is given to said owner, operator, or occupant within a reasonable time prior to said demolition.
G. Nothing herein contained shall be interpreted as precluding any private right of action of any person against an owner, operator, or occupant of the placarded structure.
