When any person is adjudged guilty of erecting, causing, maintaining, contriving or carrying on a nuisance, the city police judge may, in addition to the fine or imprisonment, if any is imposed, order that the nuisance be abated or removed, at the expense of the defendant, and after inquiry into and estimating, as nearly as may be, the sum necessary to defray the expense of the abatement, the police judge may issue a warrant therefor.
