(A) Whenever the Board of Health of the county ascertains from examination or reports of its inspectors, sanitary officers, or otherwise that a public nuisance exists, as defined in § 93.16, in or upon any structure or building, or portion thereof, and is of the opinion that the nuisance is capable of being abated without immediate vacation of the premises or that portion thereof, it shall serve notice upon the owner of the house or his or her lessee or agent, or the person in possession, charge, or control thereof, directing him or her to abate the nuisance and remove the unclean or unsanitary conditions within such reasonable time as may be fixed by the Board and specified in the notice. It shall then be the duty of the owner, agent, or person to abate the nuisance within that time.
(B) Whenever the abatement does not take place within that time, or whenever, in the opinion of the Board, the abatement is impossible or impracticable without an immediate vacation of the house or portion thereof, the Board shall serve notice upon the owner, lessee, agent, or person in possession, charge, or control thereof to vacate or cause the vacation of the house or portion thereof designated in the notice. It shall then be the duty of the owner, lessee, agent, or person to vacate or cause the vacation of the house or portion thereof within 20 days from the date of the service of the notice, or within a shorter time (not less than 24 hours in any case) as may be specified in the notice.
(C) Whenever, either in addition to or without the service of the notices on the owner, lessee, agent, or person in possession, charge, or control, the Board is of the opinion that the nuisance can be abated by a tenant or other occupant of the house or portion thereof, and the notices, either for abatement of the nuisance or for vacation of the premises, are served upon the tenant or other occupant, then it shall be the duty of the tenant or other occupant to comply with the terms of the notices and to abate the nuisance or vacate the premises accordingly.
(D) After any notice or order of vacation it shall be unlawful to occupy or permit the occupancy of the premises or portion thereof until the nuisance shall have been completely abated and the building or portion thereof shall have been rendered clean and sanitary in accordance with the terms of the notices of the Board of Health.
(E) When there is no owner, agent, lessee, or person in charge, possession, or control who is a resident of or can be served in the municipality, then personal service outside of the municipality on any such owner, agent, lessee, or person in charge, possession, or control, by anyone delegated by the Board of Health to make this service, or by registered letter or, if the address of the owner, lessee, agent, or person in possession, charge, or control be unknown, or service be not secured by registered letter after effort to do so, by notice by publication once a week for two consecutive weeks in any newspaper of general circulation in the municipality, or by the posting or attaching to or on the outside of the structure or building of a copy of the notice or order consecutively for two weeks shall have the same effect as service within the municipality.
