TL;DR
Yes. Arizona requires jail time for every DUI conviction. A standard first-offense DUI carries 10 days of jail with 9 days suspended after alcohol screening. Extreme DUI carries 30 days, super extreme DUI carries 45 days, and aggravated DUI requires Department of Corrections prison time. Some sentences allow home detention or work release after a portion is served.
Arizona is one of the toughest states in the country when it comes to DUI sentencing. If you are convicted of driving under the influence anywhere in Arizona, you will be sentenced to jail time. No exceptions. The mandatory minimum applies whether you are convicted in Scottsdale City Court, Maricopa County Superior Court, Lake Havasu City Municipal Court, or any other court in the state.
The amount of jail time depends on the specific charge, your blood alcohol concentration (BAC) at the time of the stop, and whether you have prior DUI convictions within the past 84 months. Sentences range from as little as one day (after judicial reduction for a first-offense standard DUI) to six months in county jail for a second super extreme DUI, and up to prison time in the Arizona Department of Corrections for an aggravated DUI conviction.
This article breaks down every mandatory jail sentence under Arizona’s current DUI statutes, explains how judges can reduce those sentences in certain cases, and covers alternatives like home detention and work release that may be available to you.
Arizona Mandates Jail for Every DUI: The Legal Foundation
Arizona does not offer deferred adjudication, pretrial diversion, or “no jail” plea options for DUI convictions the way some other states do. The legislature has written mandatory minimum jail sentences directly into the statutes for every level of DUI offense.
Three statutes control DUI sentencing in Arizona:
ARS 28-1381: Standard DUI (BAC of 0.08 or above, or impaired to the slightest degree)
ARS 28-1382: Extreme DUI (BAC of 0.15 or above) and Super Extreme DUI (BAC of 0.20 or above)
ARS 28-1383: Aggravated DUI (felony-level offenses involving suspended licenses, third offenses, minor passengers, or wrong-way driving)
Each statute specifies a minimum number of jail days that a judge must impose. The judge cannot go below those minimums, and the defendant cannot receive probation or a suspended sentence unless the full mandatory sentence has been served. In limited circumstances described below, judges can reduce portions of the sentence if the defendant completes specific programs or installs an ignition interlock device (IID).
For more background on Arizona’s DUI framework, see our guide to DUI laws in Arizona.

How Judges Reduce Jail Time in Arizona DUI Cases
Arizona law gives judges limited authority to reduce mandatory jail sentences under specific conditions. These reductions are not automatic. The judge must agree at the time of sentencing, and the defendant must complete the required program or condition.
First Offense Standard DUI: Treatment Reduction
Under ARS 28-1381(J), a judge sentencing a first-time DUI offender may suspend all but one day of the 10-day mandatory sentence if the defendant completes a court-ordered alcohol or drug screening, education, or treatment program. If the defendant fails to complete the program, the court can reinstate the full remaining sentence.
This is the single most significant reduction available in Arizona DUI law. It turns a 10-day jail sentence into a single day.
Second Offense Standard DUI: Treatment Reduction
Under ARS 28-1381(L), a judge may suspend all but 30 days of the 90-day mandatory sentence for a second-offense DUI if the defendant completes a court-ordered treatment program. The defendant still serves 30 consecutive days.
First Extreme DUI: IID Reduction
Under ARS 28-1382(I), a judge may reduce the 30-day mandatory sentence to 9 days if the defendant agrees to install a certified ignition interlock device on every vehicle they operate for a period of 12 months. For a first super extreme DUI (BAC 0.20+), the 45-day sentence can be reduced to 14 days with the same IID requirement.
Second Extreme and Super Extreme DUI: No Statutory Reduction
The statutes do not provide any reduction mechanism for second-offense extreme or super extreme DUI convictions. The full 120-day (extreme) or 180-day (super extreme) sentence must be served. Sixty and 90 days, respectively, must be served consecutively.
Aggravated DUI: No Reduction
Aggravated DUI carries a mandatory prison sentence of 4 months (or 8 months for individuals with three or more prior DUI convictions within 84 months). There is no statutory reduction, and the sentence is served in the Arizona Department of Corrections rather than county jail.
For more information about aggravated DUI charges, see our page on aggravated DUI laws in Arizona.
What “Consecutive Days” Means in Practice
A detail that catches many people off guard is Arizona’s consecutive-day requirement. The statute language reads “not less than [X] consecutive days in jail.” This means the jail time must be served in an unbroken block. You cannot serve a few days here and a few days there.
For a first-offense standard DUI reduced to one day, this means a single continuous stay. For a second-offense standard DUI with the 30-day consecutive requirement, that means 30 straight days in custody, even if the total sentence is 90 days and portions of the remaining 60 days may be eligible for home detention or work release.
The consecutive requirement is one of the most commonly misunderstood parts of Arizona DUI sentencing. The jail time cannot be broken up around your work schedule or personal obligations. Planning for that continuous block of incarceration is something your attorney should help you prepare for well before your sentencing date.
Home Detention and Work Release Programs
Arizona does allow some DUI defendants to serve portions of their jail sentence through home detention (also called home arrest or electronic monitoring) or work release programs. These alternatives do not eliminate jail time. They allow you to serve part of the sentence outside of a jail cell.
The 20 Percent Rule
Under standard Maricopa County policy, a DUI defendant must serve at least 20 percent of their jail sentence in actual custody before becoming eligible for home detention. For a 10-day sentence, that means at least 2 days in jail before the remainder can be served on home detention. For a 90-day sentence, that means at least 18 days in custody.
This is an administrative policy, not a statutory requirement. Eligibility varies by county, and the sentencing judge can impose restrictions that override general county policies.
How to Request Home Detention
Home detention is not automatically granted. In most cases, your attorney must request it at sentencing or petition the court separately. The process typically involves:
1. Filing a motion or request with the court
2. Demonstrating stable housing with a verifiable address
3. Agreeing to electronic monitoring (GPS ankle bracelet)
4. Paying home detention fees (which can range from $15 to $25 per day depending on the county)
5. Agreeing to comply with all program rules, including random check-ins and no alcohol consumption
Violations of home detention conditions result in immediate return to jail to serve the remainder of the sentence in custody.
Work Release
Some county jails offer work release programs that allow defendants serving DUI sentences to leave the facility for work during the day and return in the evening. Maricopa County and Mohave County both have work release or work furlough options, though availability and eligibility requirements change periodically.
Work release requires employer verification, a consistent work schedule, and approval from the sentencing judge. Not every DUI defendant qualifies, and the program may not be available for all sentence lengths.
County Jail vs. State Prison: Understanding the Difference
One of the most important distinctions in Arizona DUI law is between misdemeanor DUI offenses (which carry county jail time) and felony aggravated DUI (which carries state prison time).
Misdemeanor DUI: County Jail
Standard DUI, extreme DUI, and super extreme DUI are all classified as class 1 misdemeanors under Arizona law. Sentences are served in the county jail where the conviction occurred. In Maricopa County, that means one of the facilities operated by the Maricopa County Sheriff’s Office. In Mohave County, sentences are served at the Mohave County Jail in Kingman.
County jail sentences for DUI are typically served in minimum-security or general population housing. The conditions vary by facility, but county jail for a DUI conviction is meaningfully different from a prison sentence.
Aggravated DUI: State Prison
Aggravated DUI under ARS 28-1383 is a class 4 felony (or class 6 felony for offenses involving a minor passenger). A felony DUI conviction means serving time in the Arizona Department of Corrections (DOC), which is the state prison system. The minimum is 4 months, and the person is not eligible for probation, early release, or suspended sentence until that minimum is fully served.
There is one exception: counties with populations under 500,000 may establish an aggravated DUI jail program under ARS 28-1383(N), which allows certain aggravated DUI defendants to serve their prison sentence in a county jail facility instead of DOC. Mohave County is one of the counties that may qualify for this program. Your attorney can determine whether your case is eligible.
What Jail for a DUI Actually Looks Like in Arizona
The prospect of going to jail is the part of a DUI conviction that causes the most anxiety. Here is what to expect in practical terms.
Self-Surrender vs. Immediate Custody
In most misdemeanor DUI cases, the defendant is not taken directly to jail at sentencing. Instead, the judge sets a report date (often called a self-surrender date), giving the defendant time to arrange personal affairs, notify employers, and prepare for the sentence. Self-surrender dates are typically two to four weeks after sentencing, though judges have discretion to set them sooner.
You will report to the designated jail facility on the assigned date and time. Corrections staff will process your intake (booking, property storage, housing assignment) and you will begin serving your sentence.
Daily Life During a DUI Jail Sentence
For short-stay DUI sentences (1 to 14 days), most defendants are housed in minimum-security units. Daily routines include scheduled meal times, limited recreation time, and availability of reading materials. Phone access varies by facility but is generally available at scheduled times. Visitation policies differ between Maricopa County and Mohave County facilities.
For longer sentences (30+ days), defendants may have access to work details, educational programming, or substance abuse treatment within the facility.
The Legacy of Tent City in Maricopa County
For years, Maricopa County’s outdoor “Tent City” jail was a well-known part of the DUI experience. Tent City was closed in 2017. All Maricopa County DUI sentences are now served in permanent indoor facilities operated by the Maricopa County Sheriff’s Office, including the Estrella Jail, Lower Buckeye Jail, and other facilities throughout the county.
Credit for Time Served
If you were arrested for DUI and spent time in jail before your trial or sentencing, that time counts toward your mandatory sentence. Arizona courts apply credit for time served against the total sentence imposed.
For example, if you were arrested on a standard first-offense DUI and spent one night in jail before posting bond, that one day counts toward your 10-day sentence (or your reduced 1-day sentence if the judge grants the treatment reduction). In some cases, defendants who were held for 24 hours or more after arrest may have already satisfied the reduced minimum.
Your attorney should calculate your time-served credit and present it to the judge at sentencing to ensure you receive full credit for any time already spent in custody.
How a Defense Attorney Works to Minimize Your Jail Exposure
A DUI conviction in Arizona carries mandatory jail time, but the range between the mandatory minimum and the maximum potential sentence is significant. The difference between one day in jail and 10 days in jail for a first-offense DUI is entirely dependent on the outcome of your case and the arguments your attorney presents at sentencing.
Before Conviction: Fighting the Charge
The most effective way to avoid DUI jail time is to avoid a DUI conviction. A defense attorney examines every element of your case for weaknesses in the prosecution’s evidence. Common defense strategies include:
Challenging the legality of the traffic stop
Questioning the accuracy of breath or blood test results
Examining whether field sobriety tests were administered correctly
Identifying constitutional violations during the arrest
Negotiating reduction of charges where the evidence supports it
For a full breakdown of defense approaches, see our page on ways to beat a DUI charge.
At Sentencing: Securing the Lowest Possible Sentence
If a conviction cannot be avoided, your attorney’s focus shifts to minimizing the jail sentence. This includes:
Arranging enrollment in a treatment program before sentencing to qualify for the judicial reduction
Requesting IID installation to reduce extreme DUI sentences
Presenting mitigating factors to the court (stable employment, family responsibilities, no prior record, community ties)
Requesting home detention eligibility for the non-consecutive portion of the sentence
Requesting a self-surrender date that allows time to prepare
Ensuring full credit for any time already served
The difference between a skilled attorney who knows the local court practices and judges in Scottsdale, Mesa, or Lake Havasu and someone unfamiliar with those courts can translate directly into fewer days behind bars.
Financial Costs Beyond Jail Time
Jail is the penalty that weighs most heavily on people facing a DUI conviction, but the financial consequences are also severe. Arizona DUI convictions carry a layered system of fines, assessments, and collateral costs that add up quickly.
Fines and Assessments by Offense Level
Expense
First Standard DUI
Second Standard DUI

First Super Extreme DUI
Aggravated DUI

Minimum total fines/assessments

$2,750
$4,000
These numbers represent the statutory minimums. Courts frequently impose additional surcharges, jail costs (daily incarceration fees), and probation supervision fees that push the total well above these figures.
Ignition Interlock Device Costs
Every DUI conviction involving alcohol requires the installation of a certified IID on every vehicle the defendant operates. The typical cost of an IID in Arizona includes:
Installation fee: $50 to $100
Monthly monitoring and calibration: $60 to $90 per month
Minimum duration: 12 months for most misdemeanor DUI convictions, 24 months or more for aggravated DUI
Over a 12-month period, IID costs alone run between $770 and $1,180.
Insurance Increases
A DUI conviction triggers SR-22 filing requirements with the Arizona Department of Transportation (MVD). SR-22 is a certificate of financial responsibility that your insurance company files on your behalf. The practical effect is that your auto insurance premiums will increase substantially, often doubling or tripling. Most drivers carry the SR-22 requirement for three years after license reinstatement.
Lost Wages
Jail time means time away from work. For a first-offense DUI reduced to one day, the financial impact may be minimal. For a 30-day extreme DUI sentence or a 90-day second-offense sentence, the lost wages become a significant financial burden. Employers are not required to hold your position while you serve a jail sentence, and many DUI defendants face job loss on top of the direct financial penalties.
Alternative Sentencing Options in Arizona
Arizona law provides limited alternatives to traditional jail incarceration for DUI offenses. These are not “get out of jail free” options. They are structured programs that substitute for standard incarceration under court supervision.
Alcohol and Drug Treatment Programs
Court-ordered treatment is the primary mechanism for reducing jail time on first and second standard DUI offenses. Treatment programs approved by the court may include:
Alcohol screening and assessment
DUI education courses (typically 16 to 36 hours)
Outpatient substance abuse treatment
Intensive outpatient programs (IOP)
Inpatient residential treatment (for severe cases)
Completion of treatment is what triggers the judge’s authority to reduce the jail sentence. Starting treatment early, before sentencing, strengthens your attorney’s position when requesting the reduction.
Community Service
Arizona courts may order community restitution (community service) as part of a DUI sentence. For second-offense DUI convictions, a minimum of 30 hours of community service is mandatory under ARS 28-1381(K)(3). Community service does not replace jail time. It is an additional penalty.
Traffic Survival School
Every DUI conviction in Arizona requires completion of an approved traffic survival school course. This is mandatory for all DUI levels and is administered through the Arizona Department of Transportation (MVD).
Probation
Most misdemeanor DUI defendants are placed on probation following their jail sentence. Probation terms typically last 12 to 36 months and include conditions such as no alcohol consumption, random testing, regular check-ins with a probation officer, and compliance with all court-ordered programs.
Frequently Asked Questions
Can I avoid jail entirely for a first DUI in Arizona?
No. Arizona law requires a minimum jail sentence for every DUI conviction. For a first-offense standard DUI, the mandatory minimum is 10 days. However, a judge can reduce that sentence to one day if you complete a court-ordered treatment program. You will still serve that one day in jail.
Does time spent in jail after my arrest count toward my sentence?
Yes. Arizona courts grant credit for time already served in custody. If you spent one or more nights in jail after your DUI arrest before posting bond, those days count against your mandatory sentence. Your attorney should present time-served calculations at sentencing.
What happens if I fail to complete the treatment program that reduced my sentence?
If you fail to complete the court-ordered program, the court can reinstate the full original jail sentence. The judge will issue an order to show cause, requiring you to explain why the remaining jail time should not be served. In most cases, failure to complete treatment results in serving the balance of the original sentence.
Can I serve my DUI jail sentence on weekends?
Arizona’s consecutive-day requirement means the jail sentence must be served in a continuous, unbroken block. You cannot break the sentence into weekend segments. This applies to the mandatory consecutive portion of every DUI sentence.
Is home detention available for DUI sentences?
Home detention may be available for portions of your sentence after you have served the required consecutive days in actual custody. In Maricopa County, the general policy requires at least 20 percent of the sentence to be served in jail before home detention eligibility begins. Availability varies by county, and the sentencing judge has final discretion.
What is the difference between extreme DUI and super extreme DUI?
Extreme DUI applies when your BAC was between 0.15 and 0.199. Super extreme DUI applies when your BAC was 0.20 or above. The mandatory jail minimums are 30 days and 45 days, respectively, though both can be reduced with IID installation. For full details, see our extreme and super extreme DUI guide.
Will I go to prison for a DUI?
Only if you are charged and convicted of aggravated DUI under ARS 28-1383. Aggravated DUI is a felony that carries a mandatory prison sentence of at least 4 months in the Arizona Department of Corrections. Standard, extreme, and super extreme DUI are misdemeanors that carry county jail time, not prison. See our page on aggravated DUI laws in Arizona for more information.
How can a lawyer help if jail is mandatory?
A defense attorney can fight the DUI charge itself to avoid conviction. If conviction is unavoidable, the attorney works to secure the lowest possible sentence by enrolling you in treatment programs, arranging IID installation for extreme DUI reductions, presenting mitigating factors, requesting home detention, and ensuring you receive credit for time served. The difference between the mandatory minimum and the maximum sentence for any DUI level is substantial.
Facing a DUI Conviction in Arizona? Talk to a Defense Attorney Before Your Sentencing Date.
The amount of jail time you serve after a DUI conviction depends on the specific charges, your prior record, and the arguments your attorney presents to the court. Early intervention, including enrollment in treatment programs before sentencing, gives your defense the strongest possible foundation for requesting reduced jail time.
