It is the duty of the building inspector to enforce the provisions of this chapter respecting the duty of the owners, agents or lessees to number buildings, and any person who fails to do so for a period of thirty days after being notified in writing by the Clerk shall be deemed guilty of a misdemeanor and the City may proceed to place a suitable number on said building. The Council may assess the cost thereof against the property and collect the same in the same manner as general property taxes.
