False Alarms

In an effort to reduce the frequency our officers respond to false commercial security alarms, any business that violates City Code (154-20) will be subject to a fine.

We will not consider all false alarms as “billable”.  Evidence that violent weather conditions, electrical power failures, transmission line malfunctions, or other extraordinary circumstances beyond the control of the alarm user will not count as a billable event.  

The Police Department will send warning letters to any business after a police officer recorded a second billable false alarm within a 12 month period. Any business that accumulates four or more billable false alarm activations within a 12 month period will be subject to fines as noted in the right-hand column.
