Maricopa County DUI Guide

Maricopa County's own DUI enforcement rate runs around 480 arrests per 100,000 residents, one of the highest in the country. The county drives most of Arizona's estimated 35,000 DUI arrests a year simply on population: it's home to roughly 4.5 million people, about 62 percent of the state's total. If you or someone in your family was just arrested, here's what actually happens next, and which deadlines you cannot afford to miss.

Booking at the ITR Facility

Nearly every custodial DUI arrest in the county funnels through one building: the Intake, Transfer, and Release facility at 2670 S 28th Dr in Phoenix. It replaced the old 4th Avenue Jail intake process in 2020 and now processes about 100,000 bookings and 90,000 releases a year out of a single building covering 190,000 square feet. Booking includes a medical screening, fingerprinting and photographing, and an inventory of your personal property.

You're entitled to an Initial Appearance before a magistrate within 24 hours of arrest. These hearings run roughly every three hours, around the clock, inside ITR. The judge reviews a tool used to assess risk, sometimes called "the Matrix," that weighs your criminal history, community ties, and any prior failures to appear, then decides whether you're released on your own recognizance or held on a secured bond.

Where you're housed matters for how fast you get out. Inmates get sorted into facilities like Lower Buckeye, Estrella (the county's women's jail), and Towers based on classification, but release only happens at ITR. Unless you land in ITR's own "512 Facility," a specialized unit for people likely to bail out or get OR release within 72 hours, expect a transport delay of two to six hours between "release ordered" and actually walking out.

Bail and Release

People facing a first misdemeanor DUI who live in the county and have no record are often released on their own recognizance. If the judge sets a secured bond instead, you have two options: post the full amount in cash with the Clerk of Court, which is refunded later minus fines and fees, or pay a bail agent a premium, typically 10 percent of the bond. Arizona treats that premium as fully earned the moment it's posted, and you don't get it back even if the case is dismissed the next morning. This site's directory lists licensed bail bondsmen serving Maricopa County if you need one.

One rule worth knowing before you call anyone: Arizona law (A.R.S. § 20-340.03) bars bail agents from suggesting or recommending a specific attorney to a defendant or cosigner. It's a statute meant to prevent kickbacks, and it's enforced strictly enough that reputable agents won't even bring the subject up.

Cash bonds get paid at a kiosk in the ITR lobby or at Clerk of Court windows. Surety bonds are typically posted at the 4th Avenue Jail's north entrance, even though the actual release still happens at ITR. Two logistical traps catch families off guard: the window for posting a bond at 4th Avenue closes for roughly an hour around each shift change (early morning, mid-afternoon, and late evening), and MCSO can release money from an inmate's account without command approval only during the first 72 hours in custody. After that, getting cash out for a bondsman's fee requires slower administrative approval.

Which Court Hears the Case

A standard DUI charge under A.R.S. § 28-1381 is a misdemeanor. It lands in whichever Justice Court covers the precinct where you were stopped — the county runs 26 of them — unless a city police department made the arrest, in which case the case goes to that city's own municipal court. For cited (non-custodial) defendants, arraignment typically happens 30 to 60 days out, with a pretrial conference roughly a month after that. Lab backlogs are common enough that a misdemeanor case can sit in the pretrial phase for three to six months.

If aggravating factors apply, such as a suspended license at the time of the stop, a third DUI within 84 months, a minor under 15 in the vehicle, or driving without an interlock ordered by the court, the charge becomes felony Aggravated DUI under A.R.S. § 28-1383 and moves to Superior Court. One naming quirk to know if you're heading downtown: the courthouse at 620 W. Jackson St. houses the Encanto, South Mountain, and West McDowell precincts, plus what used to be called the "Downtown" precinct. It was renamed El Centro Justice Court specifically to stop people from queuing at the wrong window.

Diversion, the option to get charges dismissed after completing a program, is generally off the table for DUI. Maricopa County Attorney's Office policy excludes DUI offenses outright, and a 2025 revision capped eligible restitution at $2,000 for any diversion case, further narrowing who qualifies for anything. The one exception is the Veterans Treatment Court, available under a separate MCAO policy to defendants whose offense connects to a condition tied to their service, like PTSD. Completing that program can end in a reduced or, in limited cases, dismissed charge.

The License Suspension Clock: 15 Days

Separately from the criminal case, the Arizona MVD moves to suspend your license the moment you fail or refuse a chemical test. This is a civil action decided on a lower burden of proof than the criminal case, so you can beat the DUI charge in court and still lose your license. A test result of 0.08 or higher triggers a suspension lasting 90 days under A.R.S. § 28-1385. Refusing the test is worse: a first refusal costs 12 months under A.R.S. § 28-1321, and a second refusal within 84 months doubles that to two years.

The arresting officer hands you a yellow temporary permit and a pink form for requesting a hearing on the spot. From that date, you have 15 days, including weekends and holidays, to request a hearing before the suspension becomes automatic. Hearings for Maricopa County drivers are held at the Executive Hearing Office in Phoenix, not the general Office of Administrative Hearings across town. Drivers who show up at the wrong building lose the day.

Since Senate Bill 1334 took effect, the old 90-day wait before applying for a restricted license is gone. You can apply for a Special Ignition Interlock Restricted Driver License the moment the suspension starts, provided you install a certified interlock device, complete an alcohol screening with a provider approved by the court, and have no other holds on your license. Plan on needing SR-22 insurance too. Once the suspension period ends, reinstating the license costs a $50 Admin Per Se fee and a $20 reinstatement fee, paid to ADOT.

Getting Your Car Back

Maricopa County has no single "county impound lot." Where your car sits depends on who arrested you. MCSO contracts mainly with Priority Towing, which runs yards on West Lower Buckeye Road in Phoenix, in Chandler, and a Phoenix overflow lot. Call 602-232-6006 before driving anywhere; the yard varies by where you were stopped. Phoenix PD splits the city into towing zones instead, using DVT Enterprises in the north valley, Western Towing in the west valley, and All City Towing for the northeast and south central zones.

An impound connected to a DUI under A.R.S. § 28-3511 triggers a mandatory 20-day hold. You can contest whether the tow was valid, but only within 10 days of the notice under A.R.S. § 28-3514. Miss that window and you've effectively admitted the impound was valid, fees and all. Early release before day 20 is possible in a few situations under A.R.S. § 28-3512: a spouse with a valid license can retrieve a vehicle classified as community property after signing an agreement not to let you drive it for a year, and a certified installer can access the car to fit an interlock device without the tow yard charging extra for entry.

Expect a $150 administrative fee paid to the impounding agency, plus towing and storage paid to the tow company separately. MCSO's tow rate runs about $80 an hour plus $5 a mile; storage on a statutory hold is capped at $25 a day. Retrieving personal belongings, car seats, phones, wallets, is free during normal business hours no matter what you still owe. You'll need a photo ID, proof of ownership, and proof of Arizona insurance to drive the car away yourself.

Monitoring and DUI Court

If you're ordered onto electronic alcohol monitoring, whether as a bond condition or a DUI Court sentence, the supervision in Maricopa County runs through a handful of court-approved monitoring vendors. Installation typically runs $50 to $100, then $10 to $15 a day depending on whether it's alcohol monitoring alone or combined with GPS house arrest. DUI Court itself is reserved for offenders considered higher risk, often those with a Super Extreme BAC over 0.20. It's a probation track entered after a guilty plea, built around frequent testing and weekly court appearances, not a way to avoid a conviction.
