If the owner, agent of the owner, lessee, occupant, or person in possession of the premises fails to take such action as required by the notice and within the time therein provided, or as extended by the council, the designated city official shall take the action as specified in the notice to abate the unlawful condition. The official shall then prepare a statement of the expense incurred in abating the unlawful condition and shall file such statement with the city clerk. Such statement shall refer to the particular premises, and shall describe such premises in such a way that it is easily identifiable. Such statement shall also show the cost of the action taken; provided, however, if the premises include more than one lot, each separate lot, or all of the lots may be set forth in the same statement. (1962 Code §§ 5-5.305, 7-6.09, 7-8.07, 7-8.08)
