The purpose of this Chapter 8.13, is to treat false alarms separately from nuisances as defined and regulated in Chapter 8.12. False alarms not caused by attempted break-ins or fire occurring on building premises not only divert police from patrol and service duties, but cost the city thousands of dollars each year from officer time spent in investigating alarms. To recoup these costs, it is necessary for the city to recover its costs associated with these responses. It is a defense to any fee charged by the city that evidence existed of forced entry or an attempted break in. The owner and/or tenant responsible for use and occupancy of the premises shall report any such evidence to the city police department in a signed written report.
