When upon investigation or inspection by the City Health Officer, or any of his assistants, it shall have been found that any building, property or place in which any person or persons dwell, or engage in any occupation, or assemble, is kept or permitted to be or remain in an unsanitary or filthy condition, is not lighted or ventilated as required by City ordinance, in which the drainage or plumbing is so defective or unsanitary as to constitute a danger to health, or where the construction or condition of a building or part thereof is such as to endanger health, it shall be the duty of the Health Officer to notify in writing the owner, agent or occupant of such building or property, stating therein the condition or thing to be corrected, and requiring that the same be corrected within a reasonable time to be specified in such notice. If within such time the condition be not remedied, it shall be the further duty of the Health Officer to post or cause to be posted in a conspicuous place on such building or property a notice stating that such building or property has been found to be dangerous to health and unfit for occupancy. Such posted notice shall require that the premises be vacated until the dangerous condition has been corrected and the premises again have been inspected and found to be in a healthful condition, whereupon the Health Officer shall remove the notice so posted. It is unlawful for any person, other than the Health Officer or his duly authorized agents, to remove, destroy, deface, cover up or conceal any notice posted as herein provided, except by written permission of the Health Officer.
In case an order to vacate is not complied with within the time specified, the Health Officer or his duly authorized agent shall institute such legal action against the owner or occupant as may be appropriate. The Health Officer may extend the time within which to comply with the order, and whenever he is satisfied that the danger from the dwelling has ceased to exist, or that the dwelling is fit for human habitation, may revoke such order.
