   (f)   If the nuisance is not abated within the required time, the Inspector shall cause its abatement and  shall report the cost thereof to Council which may assess the same on the real estate on which the nuisance existed or the cause or source thereof was located.
   (g)    When the cause or source of a nuisance exists on property owned by the City, the Inspector shall, and in any other case he or she may, abate the nuisance at the expense of the City and no notice shall be required preliminary to the abatement.
