Alarm System Registration

The Larimer County Sheriff's Office and Crywolf co-manage our local false alarm reduction efforts in unincorporated Larimer County.  Larimer County developed an Ordinance in 2005 (available in pdf format at the bottom of this page) that requires permits for burglar alarm systems installed in both commercial and residential properties within unincorporated Larimer County. Properties inside town and city limits are exempt.

Business and homeowners should know that any burglar alarm system installed that may result in the response of the Sheriff's Office requires a permit, which must be applied for at the time of installation.  The first year cost to you is $50.00, and renewals cost $25.00 annually.  Alarm installation companies are also required to pay for permits to operate within unincorporated Larimer County.

All burglar alarm related business is managed by our program administrator, Crywolf.  You can register your alarm online and click on "New Alarm Users." Or, you may print the Registration from the website, complete the form and make your check payable to "Larimer County False Alarm Reduction Program" then mail the completed form along with your checks to:
