A. General. When a structure or equipment is found by the code official to be unsafe, or when a structure is found unfit for human occupancy, or is found unlawful as defined in Subsection A(4) , such structure shall be condemned pursuant to the provisions of this article. (1) Unsafe structures. An unsafe structure is one that is found to be dangerous to the life, health, property or safety of the public or the occupants of the structure by not providing minimum safeguards to protect or warn occupants in the event of fire, or because such structure contains unsafe equipment or is so damaged, decayed, dilapidated, structurally unsafe or of such faulty construction or unstable foundation that partial or complete collapse is possible. (2) Unsafe equipment. Unsafe equipment includes any boiler, heating equipment, elevator, moving stairway, electrical wiring or device, flammable liquid containers or other equipment on the premises or within the structure which is in such disrepair or condition that such equipment is a hazard to life, health, property or safety of the public or occupants of the premises or structure. (3) Structure unfit for human occupancy. A structure is unfit for human occupancy whenever the code official finds that such structure is unsafe, unlawful or, because of the degree to which the structure is in disrepair or lacks maintenance, is insanitary, vermin- or rat-infested, contains filth and contamination or lacks ventilation, illumination, sanitary or heating facilities or other essential equipment required by this article, or because the location of the structure constitutes a hazard to the occupants of the structure or to the public. (4) Unlawful structure. An unlawful structure is one found in whole or in part to be occupied, used or maintained or was erected or altered contrary to law. B. Closing of vacant structures. If the structure is vacant and unfit for human habitation and occupancy, and is not in danger of structural collapse, the code official is authorized to post a placard of condemnation on the premises and order the structure closed up so as not to be an attractive nuisance. Upon failure of the owner to close up the premises within the time specified in the order, the code official shall cause the premises to be closed through any available public agency or by contract or arrangement by private persons, and the cost thereof shall be charged against the real property upon which the structure is located and shall be a lien upon such real property. The assessment of costs shall be administered in accordance with the procedures set forth in Article V of this chapter. C. Notice. Whenever the code official has condemned a structure or equipment under the provisions of this subsection, notice shall be posted in a conspicuous place in or about the structure affected by such notice and served on the owner or the person or persons responsible for the structure or equipment in accordance with § 151-53C . If the notice pertains to equipment, it shall also be placed on the condemned equipment. The notice shall be in the form prescribed in § 151-53B . D. Placarding. Upon failure of the owner or person responsible to comply with the notice provisions within the time given, the code official shall post on the premises or on defective equipment a placard bearing the word or words "condemned," "unsafe" or "restricted use," as deemed appropriate by the code official, and a statement of the penalties provided for occupying the premises, operating the equipment or removing the placard. E. Prohibited occupancy. Any person who shall occupy a placarded premises or shall operate placarded equipment, and any owner or any person responsible for the premises who shall let anyone occupy a placarded premises or operate placarded equipment shall be liable for the penalties provided by this article. F. Removal of placard. The code official shall remove the condemnation placard whenever the defect or defects upon which the condemnation and placarding action were based have been eliminated. Any person who defaces or removes a condemnation placard without the approval of the code official shall be subject to the penalties provided by this article.
