An ankle monitor in Arizona is a court-ordered tracking device that uses GPS, radio frequency, or alcohol-sensing technology to confirm where you are and, in some cases, whether you have been drinking. Judges can require one before trial, as a condition of probation, or after a parole violation, and in a few situations the law takes the choice out of the judge’s hands. The rules you have to follow, who pays, and what happens if something goes wrong all depend on the stage of your case.
When an Arizona Court Can Order an Ankle Monitor
Several statutes give Arizona courts and corrections agencies authority to impose electronic monitoring, and the trigger is different at each stage.
Before Trial
Under Arizona Revised Statutes 13-3967, a judge setting release conditions can restrict travel, associations, and living arrangements for anyone released on bail or their own recognizance.1Arizona Legislature. Arizona Code 13-3967 – Release on Bailable Offenses Before Trial Electronic monitoring is one tool the court can add to that package. Judges weigh the seriousness of the charges, criminal history, community ties, and the risk of flight or danger before layering a monitor on top of standard release conditions.
Pretrial monitors commonly enforce no-contact orders and geographic boundaries. A defendant accused of stalking or domestic violence may be ordered to stay a set distance from the alleged victim, with GPS verifying compliance in real time. Travel limits also discourage flight across state lines.
Mandatory Monitoring for Certain Sex Offenses
Two situations remove the judge’s discretion entirely. At the pretrial stage, anyone charged with a felony sexual offense under Title 13, Chapter 14, a felony under the sexual exploitation of children statutes in Chapter 35.1, or child sex trafficking under Section 13-3212 must be placed on electronic monitoring as a condition of release wherever monitoring is available.1Arizona Legislature. Arizona Code 13-3967 – Release on Bailable Offenses Before Trial
After conviction, Arizona Revised Statutes 13-902 requires lifetime-of-probation GPS monitoring for anyone convicted of a dangerous crime against children who is placed on probation, required to register as a sex offender, and classified as a level three offender. The court can charge a fee to offset the cost, deposited into the adult probation services fund. The statute also preserves judges’ discretion to order GPS for other probationers when they see fit.2Arizona Legislature. Arizona Code 13-902 – Periods of Probation Monitoring Fees
Probation and Intensive Probation
Standard probation can include electronic monitoring at the judge’s direction under 13-902.2Arizona Legislature. Arizona Code 13-902 – Periods of Probation Monitoring Fees Arizona’s intensive probation supervision program, authorized under Arizona Revised Statutes 13-914, goes further and operates as house arrest for high-risk felony offenders who would otherwise go to prison.3Arizona Legislature. Arizona Revised Statutes 13-914 – Intensive Probation Evaluation Sentence Criteria Conditions People on intensive probation must stay at home at all times except for work, school, community service, or travel their probation officer has specifically approved.4The Judicial Branch of Arizona. Intensive Probation Supervision A GPS device enforces that schedule around the clock, and an unapproved detour on the way home from work is enough to trigger an alert.
Parole and Community Supervision
Under Arizona Revised Statutes 31-402, the Arizona Board of Executive Clemency can place a person on electronic monitoring when they violate community supervision terms without committing a new offense.5Arizona Legislature. Arizona Code 31-402 – Powers of Board Powers and Duties of Governor For someone already on a monitor, the board can tighten the conditions instead.
DUI Cases and Alcohol-Sensing Bracelets
Alcohol-detection bracelets, most commonly the Secure Continuous Remote Alcohol Monitor (SCRAM), measure alcohol through perspiration and report any detected consumption to the supervising agency. Judges order them at multiple points in DUI cases: as a pretrial release condition for repeat or aggravated offenders, as a substitute for part of a jail sentence after conviction, or at the direction of a probation officer who suspects a probationer is drinking in violation of a no-alcohol condition. They are especially common in extreme DUI cases (BAC of 0.15 or higher) and super extreme DUI cases (BAC of 0.20 or higher), where mandatory minimum jail sentences push courts to look for ways to allow partial home detention with accountability.
Daily Rules for Wearing the Device
Most GPS ankle monitors need roughly one to two hours of charging every day, and a dead battery is the single most common avoidable violation. The battery either runs down or the charger disconnects, the device goes dark, and the supervising officer gets an alert.
Charge the device during a predictable, stationary stretch of your day — dinner, television, something you actually sit still for. Charging overnight sounds convenient and routinely goes wrong: a cord gets kicked loose, the charger shifts, and you wake up to a violation already in motion.
You are also responsible for keeping the device dry, intact, and attached. Submerging it, exposing it to extreme heat, or wearing clothing thick enough to block the GPS signal can all trigger alerts. If the device malfunctions through no fault of your own, document the problem immediately and contact your probation officer. A genuine technical malfunction can be a defense, but you have to show the problem was not something you caused or could have prevented.
Who Pays for the Monitor
The answer splits sharply between pretrial and post-conviction monitoring.
Before trial, counties generally cannot shift GPS costs onto the defendant. An Arizona appellate court held as much in Hiskett v. Lambert (2019), and pretrial monitoring costs typically fall on the county.
After conviction, costs usually move to the person wearing the device. Arizona Revised Statutes 13-902 authorizes probation monitoring fees and includes a specific GPS fee provision for the mandatory sex offender category.2Arizona Legislature. Arizona Code 13-902 – Periods of Probation Monitoring Fees Intensive probation carries fees of at least $75, though the court can reduce that after finding you cannot afford it.3Arizona Legislature. Arizona Revised Statutes 13-914 – Intensive Probation Evaluation Sentence Criteria Conditions Private monitoring companies that contract with county probation departments set their own rates, which vary by county. Nationally, daily monitoring fees run from a few dollars to about $35, with setup charges of $100 to $200 on top.
Falling behind on payments does not automatically send you to jail. Under Arizona Revised Statutes 13-810, the court must first hold a hearing on whether the failure to pay was willful. If the court finds you intentionally refused to pay or did not make a good-faith effort to come up with the money, it can treat the default as contempt and order jail time, revoke probation, or require community service.6Arizona Legislature. Arizona Code 13-810 – Consequences of Nonpayment of Fines Surcharges Fees Assessments Restitution or Incarceration Costs If you genuinely cannot afford the fees, raise it with your attorney or probation officer early. Waiting until you are already in default makes hardship much harder to argue.
What Happens If You Violate Monitoring Conditions
Consequences scale with the type of violation, whether it is your first, and the stage of your case. Common violations are leaving approved boundaries, missing curfew, letting the battery die, and entering prohibited locations.
For probationers, Arizona Revised Statutes 13-901 gives the judge broad authority to modify or add conditions, issue a warrant, or revoke probation entirely. If probation is revoked on multiple terms running at the same time, the court can order the resulting prison sentences to run consecutively rather than concurrently.7Arizona Legislature. Arizona Code 13-901 – Probation Probation officers can also arrest you without a warrant at any time during the probation term and bring you before the court.
For parolees and people on community supervision, the Board of Executive Clemency handles violations, and adding or tightening electronic monitoring is one of the sanctions available short of returning you to prison.5Arizona Legislature. Arizona Code 31-402 – Powers of Board Powers and Duties of Governor
Repeated violations draw far harsher responses than isolated incidents, and a willful violation almost always lands worse than an accidental one.
Tampering With or Removing the Device
Cutting off, bypassing, or interfering with an ankle monitor is a separate felony in Arizona. Under Arizona Revised Statutes 13-3725, removing or bypassing any equipment used for electronic monitoring or GPS tracking is a class 4 felony, and helping someone else do it to their device is the same offense.8Arizona Legislature. Arizona Code 13-3725 – Interference with Monitoring Devices Classification
A class 4 felony in Arizona carries a presumptive prison sentence of 2.5 years, with a first-offense range of 1 to 3.75 years. That sentence stacks on top of whatever you were already facing on the underlying charge and any probation or parole revocation. People sometimes make the worst decision of their case here: taking off a bracelet because it is uncomfortable or because they want to go somewhere off-limits turns a manageable supervision problem into a multi-year prison exposure. However frustrating the device is, removing it will always make the situation worse.
