Statutory Rape in Arizona: Age of Consent, Penalties, and Defenses

Arizona’s criminal code does not use the term “statutory rape,” but what people mean by statutory rape in Arizona is prosecuted under A.R.S. § 13-1405, which makes it a felony to engage in sexual intercourse or oral sexual contact with anyone under 18.¹ The minor’s apparent willingness is irrelevant to the charge. What determines how serious it is: the minor’s age and the defendant’s relationship to them.

Arizona Sets the Age of Consent at 18

Arizona is one of roughly a dozen states that draws the line at 18. Most states use 16, and a few use 17. The practical consequence is that sexual conduct with a 17-year-old is a felony in Arizona even when the same conduct would be legal across the state line.

The rule comes from § 13-1405 itself, which criminalizes sexual conduct with “any person who is under eighteen years of age.”¹ The minor’s age is an element of the offense, not a consent question. Prosecutors do not have to prove force or refusal. They have to prove the act and the age.

When the Minor Is Under 15

Sexual conduct with a child under 15 is a Class 2 felony and is prosecuted under the dangerous crimes against children (DCAC) sentencing framework in § 13-705. That framework imposes mandatory prison time well beyond ordinary felony ranges.¹

For a first offense, the prison range is 13 years minimum, 20 years presumptive, and 27 years maximum, whether the victim is under 12 or between 12 and 14.² These are flat-time sentences. The convicted person serves the full term imposed. Probation, suspended sentences, and early release are not available except in the narrow circumstances the Board of Executive Clemency can authorize.

A second DCAC conviction can push the sentence to natural life. Prosecutors do not have to prove the defendant knew the child’s exact age. The act and the actual age are what control.

When the Minor Is 15, 16, or 17

Once the minor has turned 15, the base offense drops to a Class 6 felony, Arizona’s lowest felony class. Two circumstances raise it:¹

Class 4 felony when the defendant is more than 60 months older than the minor and was over 21 at the time. A conviction at this level also carries a mandatory year in jail as a condition of probation.
Class 2 felony when the defendant held a “position of trust” over the minor, such as a teacher, coach, clergy member, or foster parent. At this level, probation, suspension, and early release are off the table until the full sentence is served.

At the base Class 6 level, first-time offenders are sentenced under § 13-702, and the offense can even be designated as a misdemeanor at sentencing in some situations. At the Class 4 level, first-offense prison terms run from 1 year (mitigated) to 3.75 years (aggravated), with a 2.5-year presumptive term.³ The position-of-trust enhancement at the Class 2 level is the harshest and closes off most paths to leniency.

The Close-in-Age Defense

Arizona’s version of a “Romeo and Juliet” law is a complete defense to prosecution under § 13-1405, but only when every one of these conditions is met:⁴

The minor was 15, 16, or 17.
The defendant was under 19 or still in high school.
The defendant was no more than 24 months older than the minor.
The conduct was consensual.

The defense is narrower than it looks. A 20-year-old involved with a 17-year-old does not qualify, even though the gap is only three years, because the defendant must be under 19 or in high school. A 19-year-old who is 25 months older than a 17-year-old fails the test by a single month. The defendant carries the burden of establishing each element.

The close-in-age defense does not apply at all when the victim is under 15. There is no Romeo and Juliet exception for younger children in Arizona.

Mistake of Age and Marriage

Section 13-1407 also allows a reasonable-mistake-of-age defense, but only when the victim was 15, 16, or 17. If the defendant genuinely did not know and could not reasonably have known the minor’s age, that can defeat the prosecution.⁴ When the victim is under 15, mistake of age is not a defense. It does not matter whether the child lied about their age, produced a fake ID, or looked older. The offense is strict liability for that age group.

Marriage is a separate defense under § 13-1407(A). If the defendant and the minor were legally married at the time of the conduct, it is not criminal. Arizona permits minor marriage only in limited circumstances with parental and judicial consent, so this defense exists in theory and arises rarely in practice.

Sex Offender Registration After a Conviction

A conviction under § 13-1405 triggers mandatory sex offender registration under § 13-3821. The process begins before release: the Department of Corrections coordinates with the Department of Public Safety and the county sheriff to complete initial registration while the person is still in custody.⁵ The registrant must provide identifying information, fingerprints, and photographs to the county sheriff, who forwards the data to DPS. Name, address, and conviction details appear in a public database. Failing to keep the registration current, including moving without notifying authorities, is itself a felony.

Registration is not automatically lifelong for every defendant. A court may end the requirement upon successful completion of probation if the offense was committed when the defendant was under 18.⁵ A separate petition process under § 13-3821 allows termination for defendants who were under 22 at the time, where the victim was 15 to 17, the conduct was consensual, probation was completed successfully, and the person has no subsequent felony or sexual offense. A broader petition process under § 13-923 lets probationers who committed the offense before turning 18 seek annual review.⁶ For adult defendants convicted of offenses involving victims under 15, registration continues indefinitely in practice, because DCAC sentencing eliminates probation and the termination provisions require conditions those defendants cannot meet.

When Federal Law Applies Instead

Most of these cases are prosecuted in state court. Federal charges under 18 U.S.C. § 2243 can apply when the conduct occurs on federal land, including military bases, tribal reservations, and national parks, or crosses state lines. The federal statute covers sexual acts with a person at least 12 but under 16, where the defendant is at least four years older, and carries up to 15 years in prison.⁷ Unlike Arizona’s strict-liability treatment of younger victims, the federal statute allows a reasonable-belief-of-age defense, with the defendant bearing the burden of proving that belief by a preponderance of the evidence.
