Yes, Arizona has mandatory jail for a first-offense DUI conviction. Under A.R.S. 28-1381, a first-offense standard DUI (BAC .08-.149) carries 10 days minimum with 9 days suspendable if the defendant completes court-ordered alcohol screening and treatment — meaning most defendants serve only 1 day. Extreme DUI (A.R.S. 28-1382, BAC .15-.199) has 30 mandatory days with 20 suspendable. Super Extreme DUI (.20+) has 45 mandatory with 31 suspendable. Call (480) 582-3637 for a DUI lawyer.

The Statutory Mandatory Jail Requirements
Arizona law requires mandatory jail time for all DUI convictions. The specific requirements vary by BAC and prior record:
| Charge | Mandatory Minimum | Suspendable | Actual Typical Jail |
|---|---|---|---|
| Standard DUI 1st (BAC .08-.149) | 10 days | 9 days if screening completed | 1 day (often served in home detention) |
| Extreme DUI 1st (.15-.199) | 30 days | 20 days if interlock + monitoring | 10 days |
| Super Extreme DUI 1st (.20+) | 45 days | 31 days if monitoring | 14 days |
| Standard DUI 2nd (within 84 mo) | 90 days | 60 days if interlock | 30 days |
| Extreme DUI 2nd | 120 days | 60 days | 60 days |
| Aggravated DUI (felony 3rd or child in car) | 4 months prison minimum | Not suspendable | 4 months prison |
These minimums are set by statute — A.R.S. 28-1381, A.R.S. 28-1382, and A.R.S. 28-1383. Judges cannot go below the minimums even in sympathetic cases. However, the “suspendable” portion can be waived by the court if the defendant completes required screening and treatment. This is where the actual jail time gets minimized.
How the Suspended Sentence Actually Works
The mandatory minimum is the floor. But Arizona statutes allow the court to suspend part of the sentence if the defendant completes specific conditions:
- Alcohol screening and assessment. Court-ordered evaluation by a state-approved alcohol counselor. Cost typically $150-$300.
- Follow-up treatment. Ranges from 16 hours of Level 1 (educational) to 90+ hours of Level 3+ (intensive outpatient). Cost varies from $400 to $2,500.
- Ignition interlock device installation. Under A.R.S. 28-3167, mandatory for all DUI convictions. 12 months for standard, 18 months for Extreme, 24 months for repeat offenders.
- Continuous alcohol monitoring (CAM). For Extreme and Super Extreme DUI, court may order continuous alcohol monitoring device as a substitute for jail time. Cost $250-$400 per month.
When all required conditions are met and completed on schedule, the court suspends the maximum allowable portion of the sentence. This means the actual jail time drops from the statutory minimum to typically 1-15 days depending on the charge.
Critical: the suspension is REVOCABLE if the defendant fails to complete conditions. If the defendant is arrested for another DUI or violates probation, the suspended sentence can be imposed. The suspended time hangs over the defendant’s head for the entire probation period (typically 3-5 years).
Practical Jail Time by DUI Type
Beyond the statutory minimums, the actual time served depends on several factors:
Standard first DUI: Most defendants serve 1 day of physical jail time. Some counties allow the day to be served on a weekend or through a work-release program.
Extreme first DUI: Typically 10 days served through:
- Weekend jail (Saturday-Sunday for 5 consecutive weekends)
- Home detention with ankle monitor (available in some counties)
- Work-release (defendant works during the day, returns to jail at night)
- Straight time in Maricopa County jail
Super Extreme first DUI: Typically 14 days. Same options as Extreme but with more restricted eligibility for home detention or work release due to higher BAC.
Second DUI: Actual time increases dramatically. Even Standard second DUI typically results in 30 actual days. Reducing this requires strong defense strategy and full completion of all treatment conditions.
Aggravated (felony) DUI: Not “jail” — actual prison in Arizona Department of Corrections facility. Minimum 4 months for third DUI within 84 months. Presumptive 2.5-3.5 years for aggravated DUI with prior felony history.
Home Detention and Work Release Options
Arizona counties offer alternatives to straight jail time that can significantly reduce disruption:
Home detention. Defendant serves sentence at home with electronic monitoring (ankle bracelet). Movement restricted to work, medical appointments, and court-approved activities. Available for many first-offense DUI defendants in Maricopa, Pima, and Yuma counties. Cost typically $10-$25 per day.
Work release. Defendant works during business hours, returns to a work-release facility (or jail) after work. Continues employment while serving sentence. Available in most Arizona counties.
Weekend jail. Sentence served in consecutive weekends. Sunday check-in, Monday check-out. Allows continued employment during the week.
Alcohol monitoring (SCRAM ankle bracelet). Continuous alcohol monitoring device that detects any alcohol consumption. Court may accept this as substitute for portions of jail sentence, particularly for Extreme DUI.
DUI Diversion (in some counties). First-offense standard DUI defendants may qualify for diversion programs where completion results in charge dismissal. When available, this replaces jail entirely.
Not all options are available in all counties or for all DUI classifications. Rural Arizona counties (La Paz, Greenlee, Cochise) have fewer options than Maricopa or Pima. Whether these options are available in a specific case depends on the county, the DUI classification, the defendant’s prior record, and often the specific judge assigned.
Ways to Reduce Actual Jail Time
Several strategies further reduce actual time in physical custody:
- Complete all required screening and treatment before sentencing. This makes the maximum suspension available and often demonstrates the “responsible defendant” profile that judges look favorably on.
- Install ignition interlock before sentencing. Voluntary early installation demonstrates commitment and often reduces sentencing.
- Fully cooperate with probation office intake. Speed and completeness matter. Delays or non-cooperation extend jail exposure.
- Negotiate charge reduction. Reducing Extreme to Standard DUI cuts mandatory jail by 20 days. Reducing Standard to Reckless Driving eliminates DUI jail entirely.
- Petition for home detention or work release. Petitions filed at sentencing (through defense counsel) are more successful than post-sentencing modifications.
- Documented family or medical hardship. Judges have discretion to structure sentences to accommodate documented hardships — new baby, medical treatment, sole custody of children.
- Continuous alcohol monitoring alternative. For Extreme DUI, CAM device wear can substitute for portions of jail sentence.
Combining these strategies typically results in actual physical jail time of 1-3 days for first-offense standard DUI cases with experienced defense representation. Without representation, defendants often serve the full mandatory minimum plus additional time due to procedural mistakes.
What Jail Actually Looks Like
Understanding what jail actually entails helps defendants prepare and often motivates hiring counsel to minimize it.
Booking process. Booking takes 2-6 hours. Defendant is fingerprinted, photographed, medically screened, personal belongings inventoried and stored, and issued jail-issue clothing. Personal medications must be documented and are typically re-prescribed by jail medical staff (delays common).
Housing. County jails house DUI defendants in general population unless there is documented safety concern. Cells are typically 6×9 feet with 2 bunks. Some Arizona jails have DUI-specific housing units that separate DUI defendants from general population.
Meals. Three meals per day. Nutrition-adequate but institutional. Special dietary needs (medical, religious) require documented request.
Communication. Limited to collect calls and video visits (in some facilities). Cell phones are prohibited. Books and reading material may be requested through commissary.
Time. Days feel long. Most facilities have limited outdoor recreation time. Some educational and vocational programs available for longer stays.
Medical. On-site medical staff. Chronic conditions can be maintained but medication delivery is delayed and can cause disruption to treatment. Emergency medical care is available but non-urgent care requires request through medical staff.
For a 1-day DUI sentence, booking through release typically takes 24-30 hours. For longer sentences (Extreme, Super Extreme, second offenses), the experience becomes more disruptive to normal life. Losing 10+ days of work, missing family events, and the general institutional experience often motivates defendants to aggressively pursue jail-reduction alternatives.

Frequently Asked Questions
Yes. Arizona statute A.R.S. 28-1381 requires mandatory minimum jail for all first-offense DUI convictions. Standard DUI (.08-.149) requires 10 days minimum, of which 9 can be suspended if the defendant completes alcohol screening and treatment — meaning most defendants serve only 1 day of physical jail. Extreme DUI (.15+) requires 30 days minimum with 20 suspendable. Super Extreme DUI (.20+) requires 45 days minimum with 31 suspendable.
1 day is the typical actual jail time for a first-offense standard DUI (.08-.149) after suspension conditions are completed. The full statutory minimum is 10 days, but 9 days are typically suspended when the defendant completes court-ordered alcohol screening and treatment. Extreme DUI (.15-.199) typical actual jail is 10 days; Super Extreme (.20+) is 14 days; and second-offense DUI is 30+ days.
You cannot completely avoid mandatory jail through the standard DUI conviction under A.R.S. 28-1381 — even the suspended-sentence structure requires at least 1 day of physical custody. However, several strategies significantly minimize actual time: negotiating a charge reduction (Standard DUI to Reckless Driving eliminates DUI jail entirely), qualifying for pre-trial diversion programs (available in some counties for first-offense defendants), securing home detention or work release, and challenging the case for dismissal or reduction.
Home detention allows a DUI defendant to serve their sentence at home while wearing an electronic ankle monitor. Movement is restricted to work, medical appointments, treatment programs, and court-approved activities. Available in Maricopa, Pima, Yuma, and some other Arizona counties for many first-offense DUI defendants. Cost is typically $10-$25 per day. This alternative avoids the disruption of physical jail while satisfying the mandatory custody requirement.
Yes, through work-release programs available in most Arizona counties. Under work release, the defendant works during business hours and returns to the work-release facility (or jail) after work. Continued employment allows the defendant to maintain income while serving the sentence. Alternatively, weekend jail programs allow the defendant to work Monday through Friday and serve sentence in consecutive weekends. Both options require court approval and are typically requested at sentencing.
The suspended jail time can be imposed. If the defendant violates probation conditions (new arrest, missed treatment session, failed drug test, missed probation appointment) during the probationary period, the court can revoke the suspension and require the defendant to serve the previously suspended jail time. This means a defendant who initially served 1 day of a 10-day standard DUI sentence could be required to serve the remaining 9 days if they violate. Probation periods are typically 3-5 years, so this suspended time is a substantial ongoing risk.
First DUI has mandatory jail but the actual time can be reduced from 10 days to 1 with proper defense. Home detention and work release preserve employment. Derek Oliverson defends Arizona DUI cases since 2009.
