The legislative body may compel the owner, lessee, or occupant of buildings, grounds, or lots to remove dirt, rubbish, weeds, and rank growths from buildings or grounds and adjacent sidewalks. If he defaults, after notice prescribed by the legislative body, it may authorize the removal or destruction of the dirt, rubbish, weeds, and rank growths at his expense by a city officer. The legislative body may prescribe a procedure for the removal or destruction and make the expense a lien upon the buildings or grounds.

By ordinance the legislative body may:
  (a) Require and provide for the removal of grass, weeds, or other obstructions from the sidewalks, parkings, or streets and make the cost of removal a lien upon the abutting property.
  (b) Require or provide for the removal from property, lands, or lots of all weeds, rubbish, or other material dangerous or injurious to neighboring property or the health or welfare of residents of the vicinity and make the cost of removal a lien upon the property.
  (c) Provide for the enforcement of the lien by the sale of the property or otherwise.
