If a nuisance or any insanitary conditions are found by the health commissioner, deputy sanitary officers and police upon making a sanitary survey, it shall be the duty of the Health Officer, when informed of the existence of such conditions, to notify immediately the person so offending, in writing, fixing a time limit to abate the nuisance. If such person shall fail or refuse to abate the nuisance, within the time specified, it shall be the duty of the street commissioner, upon notice of the Health Officer, to cause such nuisance to be abated, keeping an accurate account of the expense thereof, which shall be paid from the city treasury upon the sworn voucher of the Street Commissioner, and such expense shall be a lien on the property, and collected as taxes are collected, and turned into the city treasury.
