Infected and uninhabitable dwellings to be vacated. Whenever it shall be certified by an inspector or officer of the health department that a dwelling is infected with contagious disease or that it is unfit for human habitation, or dangerous to life or health by reason of want of repair, or of defects in the drainage, plumbing, lighting, ventilation, or the construction of the same, or by reason of the existence on the premises of a nuisance likely to cause sickness among the occupants of said dwelling, or for any cause, the health officer or such other appropriate public official as the mayor may designate, may issue an order requiring all persons therein to vacate such house within not less than 24 hours nor more than 10 days for the reasons to be mentioned in said order. In case such order is not complied with within the time specified, the health officer or such other appropriate public official as the mayor may designate may cause said dwelling to be vacated. The health officer or such other appropriate public official as the mayor may designate whenever he is satisfied that the danger from said dwelling has ceased to exist, or that it is fit for human habitation may revoke said order or may extend the time within which to comply with the same.
