Tarrant County Alarm Permit: Cost, False Alarm Fees and How to Register
In unincorporated Tarrant County (outside any city or town), alarm permits come from the Sheriff's Office, which currently lists the fee as $30 a year (an older county order still posted online says $25); houses and duplexes need one once the Sheriff has received any alarm notification from the system. Your first 5 false alarms in any 12 months are free, and each one after that costs $75, with or without a permit. If you live inside a city, your city's police department handles alarm permits instead.[1,2]
Tarrant County alarm permit at a glance
| Who needs a permit | This permit only covers homes and businesses in unincorporated Tarrant County, outside any city or town limits. If you live inside a city or town, contact that city's police department for its alarm permit instead.[1,2,3] |
|---|---|
| Which alarms are covered | You need a permit for an alarm that can call out deputies, fire or emergency responders at a property in unincorporated Tarrant County. Houses and duplexes need one once the Sheriff has received any alarm notification from the system; car alarms and government buildings are exempt.[2] |
| Residential permit fee | Sources differ The Sheriff's Office page and its 2026 application form say an alarm permit costs $30 a year, and the county's FY2026 fee schedule (titled Proposed) also lists $30. The older county alarm order still posted online says $25, so confirm with the Sheriff's Office at 817-884-1323 if the amount matters. For apartment complexes, the proposed FY2026 schedule lists $60 per 100 units, while the older order says $50 per 100 units; we couldn't confirm which applies.[1,3,2,4] |
| Fee exemptions | County, state and federal government sites don't need a permit, and other public bodies need one but pay no fees. These don't count as false alarms: a real crime, fire or other emergency; severe weather that damages the property; a proven phone-line failure; alarms where a deputy arrived more than 30 minutes after the call; and alarms in a new system's first 30 days if you applied for the permit before it went live. We found no senior or low-income waiver.[2,1] |
| Free false alarms | 5 in any rolling 12 months[2] |
| If you have no permit | Not confirmed. The county's alarm order doesn't say deputies will refuse to respond to an alarm without a permit; it treats a missing permit as a ticketable offense instead. |
| Runs the program | Tarrant County Sheriff's Office, Communications Division[1,2] |
| When to apply | Houses and duplexes need a permit once the Sheriff has received any alarm notification from the system (not only a false alarm); businesses and other sites need one before the alarm is used. If you apply before your new system goes live, false alarms in the first 30 days don't count against you.[2,1] |
False alarm fees in Tarrant County
False alarms are counted over any rolling 12 months[2]. Each fee below is charged per false alarm.
Residential false alarms (with a permit)
If false alarms keep happening: The Sheriff shall revoke a permit for a false statement on the application, violating certain alarm rules, or not paying a false alarm fee within 30 days after receiving notice to pay; more than nine false alarms within any 12 months is also grounds for revocation. Using the alarm while the permit is revoked is an offense. The Sheriff sends written notice by certified mail; you can appeal by filing a written request for a hearing with the Commissioners Court Administrator within 10 days after you receive it, and a timely appeal puts the revocation on hold until the Commissioners Court decides.[2]
Charges without a permit
- $75 — charged for each false alarm after the fifth in any 12 months, the same as at a permitted site. Operating an alarm without a required permit is also a Class C misdemeanor, with the fine set by the court.[2]

Good to know
- Self-installed and self-monitored systems: Not confirmed. The county's alarm order doesn't say anything specific about self-installed or self-monitored systems. Because houses only need a permit after an alarm has triggered a call to the Sheriff, check with the Sheriff's Office (817-884-1323) if your system isn't professionally monitored.
- Panic and hold-up alarms: Not confirmed. We found no separate permit or fee rules for panic, hold-up or robbery alarms in unincorporated Tarrant County; the same permit and $75 false-alarm fee rules appear to apply to all alarm types.
- Before police are sent: Not confirmed. We found no rule requiring an alarm to be verified (for example by video or a guard) before deputies respond in unincorporated Tarrant County.
- Not sure which rules apply to your address?: Not sure if you're in a city or unincorporated county? The Sheriff's Office suggests checking your property record on the Tarrant Appraisal District website.[1]
Business and other non-residential alarms
Avoiding false alarms
- Make sure everyone who has a code knows how to disarm the system and cancel an alarm.
- Keep your monitoring company's contact list up to date so they can reach someone quickly.
- Let your monitoring company know before guests, contractors or pet sitters use the house.
- Check that doors and windows are fully closed before you arm the system.
- Replace low sensor batteries promptly.
