Alarm Permits in Unincorporated Tarrant County Go Through the Sheriff

A monitored alarm outside any city limits in Tarrant County is a Sheriff's Office matter. The sheriff issues alarm permits for those county areas, and the permit runs for one year.

The easy mistake is assuming the county permit covers a city address. It usually does not. Fort Worth, Arlington, and other Tarrant cities have their own alarm programs and false-alarm fees.

For a rural county address, handle the application, fee, and renewal before the alarm company turns the system on. That keeps the permit matched to the right office.
