At the hearing the property owner may contend that he or she has no ownership interest in the property, or that no nuisance exists, as defined herein, or that some other reason exists why the nuisance ought not to be abated, or why he or she should not be liable for the cost of abatement. At the conclusion of the hearing the council or committee or presiding officer shall either order that the nuisance be abated by the property owner or by the city at his/her expense, or by the city at the city's own expense, or that it not be abated, or that new proceedings be commenced by the city. (Ord. M-2804 §5, 1989)
