Bexar County Alarm Permit: Registration, Renewal, and False Alarm Fees

If you operate a burglar, panic, or holdup alarm on property in unincorporated Bexar County, you need a Bexar County alarm permit issued by the Sheriff’s Office Alarm Detail before the system is turned on. Skip it and you’re looking at a Class C misdemeanor with fines up to $500, plus a $75 fee for every alarm activation with no free alarms to draw on.¹² The permit requirement applies only to unincorporated areas. If your property sits inside San Antonio or another incorporated city, you fall under that municipality’s own alarm ordinance instead.

Who Has to Register

Any person who operates an alarm system on property in unincorporated Bexar County needs a permit before activating it, whether the property is residential or commercial.¹ The county’s authority to require this comes from Texas Local Government Code Chapter 233, Subchapter D.³

Three categories are exempt: premises occupied by the United States government, the State of Texas, and Bexar County itself. Any property inside an incorporated city is also outside these rules.¹

What the Application Asks For

The permit holder has to be an individual. The Sheriff’s Office does not issue permits under a company name, so for a commercial site, the owner or manager applies personally. The form asks for your full name, driver’s license number (used to distinguish applicants with similar names), home address, and daytime, mobile, and nighttime phone numbers.⁴

You’ll also list two emergency contacts the Sheriff’s Office can reach if they can’t get hold of you, each with day, mobile, and night numbers, along with the name of your alarm company.⁴ Keep this information consistent with what your monitoring company has on file. Mismatched contacts slow down response and verification during a real event.

Submitting and Paying

The application is available on the Bexar County Sheriff’s Office website or at their administrative office. Submit it with a non-refundable payment by check or money order.⁴ The Sheriff’s Office sets the fee, and it can adjust that amount under its statutory authority, so confirm the current figure on the application form or by calling the Alarm Detail directly.³

Once your application is approved and payment processed, the permit is tied to the specific address on the application. Keep it at the alarm location and produce it if a deputy or Sheriff’s representative asks to see it. A permit cannot be transferred to another person or another property.¹

Renewing Every 12 Months

Each permit is valid for 12 months from the date of issuance and expires on the last day of the twelfth month. The Sheriff’s Office sends a renewal notice at least 30 days before expiration with your expiration date, renewal instructions, and the fee. Not receiving the notice does not excuse a late renewal.¹

File the renewal application and fee with the Alarm Detail before your permit expires. The renewal counts as timely on the date it’s received, not the date you mailed it, so leave yourself a buffer. Before processing a renewal, the Sheriff’s Office checks for outstanding fees, fines, or court judgments owed to Bexar County from alarm-related matters. Any balance has to be cleared first.¹

If you sell the property, the new owner cannot use your permit. They have to apply for their own before the alarm can operate.¹

False Alarm Fees

A false alarm is any alarm signal law enforcement responds to that turns out not to involve a crime, attempted crime, or other genuine emergency. A permitted system gets five free false alarms per 12-month term. After that, each additional false alarm costs $75.¹ State law also caps the per-alarm fee at $75.³

Intentional false alarms are treated differently. If you or someone acting on your behalf knowingly triggers an alarm for a non-emergency, the county can charge the full cost of its response rather than the $75 flat fee.³

Revocation and Appeals

More than nine false alarms in a single permit term (the five free ones included) can trigger revocation. After a revoked permit is reinstated, three more false alarms during the remainder of that term will revoke it again, and you’ll wait six months before you can apply for reinstatement.¹

If your permit is revoked or your application denied, you can request an administrative hearing by submitting a written request to the Alarm Detail within 10 days of receiving the revocation notice. Receipt is legally defined as 10 days after the certified mailing date, so the deadline runs whether or not you open the letter. The Alarm Detail then schedules the hearing within 30 days. The Sheriff or a designee runs it informally; you can bring a lawyer but aren’t required to, and both sides can present and cross-examine witnesses. The hearing officer has discretion to adjust fees and charges for good cause, so documented equipment failures or weather events are worth raising.¹

Operating Without a Permit

An unpermitted alarm is a Class C misdemeanor under county rules and state law, with a fine of up to $500.¹² The permit application spells out the range: $50 to $500 plus court costs for each alarm activation at an unpermitted site. Every false alarm at an unpermitted location also carries the $75 fee from the first one. The five-alarm grace period only exists for permitted systems.⁴

Cutting Down on False Alarms

Most false alarms trace back to user error when arming or disarming, loose doors or windows that trip motion sensors, pets setting off interior detectors, and aging equipment with dying batteries or faulty wiring. Each of these has a straightforward fix.

Train everyone in the household or business on how to operate the system and how to cancel an accidental trigger before the monitoring company dispatches law enforcement. Schedule an annual inspection with your alarm company; one service call is cheaper than four false-alarm fees. If you have pets, ask about pet-immune motion sensors, which ignore movement below a set weight threshold. And keep your emergency contact information current with the Sheriff’s Office, because reaching someone who can verify a false alarm quickly can keep it from being logged against you in the first place.
