The age of consent in California is 18. Penal Code §261.5 makes sexual intercourse with a person under 18 who is not the perpetrator’s spouse “unlawful sexual intercourse.” California has no general Romeo-and-Juliet exemption, although the age difference can substantially affect how the offense is charged and punished.
California’s age-of-consent law sounds straightforward because it centers on one number: 18. The details get more complicated when two teenagers are close in age, an older person reasonably believes someone is already 18, or a case involves sexual conduct covered by statutes other than Penal Code §261.5. Recent changes to California’s sex-offender-registration law also make it especially important to use current information rather than older legal summaries.
What Is the Age of Consent in California?
The age of consent in California is 18. The official text of California Penal Code §261.5 defines a minor as a person under 18 and an adult as a person who is 18 or older. The same section defines unlawful sexual intercourse as intercourse with a minor who is not the perpetrator’s spouse. That means a person under 18 generally cannot make sexual intercourse lawful simply by agreeing to it.
California uses the statutory term “unlawful sexual intercourse,” although the offense is commonly described as statutory rape. The law does not require prosecutors to prove that force or coercion was used for a charge under §261.5 because the younger person’s age is the central issue. Cases involving force, threats, incapacity, or substantially younger children can fall under different and potentially much more serious criminal statutes.
California Penal Code §261.5 at a Glance
The consequences under §261.5 depend heavily on the age difference between the people involved. A small age gap does not make the conduct legal, but it can keep the offense at the misdemeanor level, while larger gaps can allow felony prosecution. The statute also authorizes separate civil penalties for adults that increase as the age difference grows.
| Situation | Criminal treatment under §261.5 | Potential civil penalty for an adult |
| Minor is within 3 years of the other person. | Misdemeanor | Depends on exact age gap |
| The minor is more than 3 years younger. | Misdemeanor or felony | Up to $10,000 when the minor is at least 3 years younger |
| The person is 21 or older, and the minor is under 16. | Misdemeanor or felony; the felony term can be 2, 3, or 4 years. | Up to $25,000 |
| Adults and minors are less than 2 years apart. | The criminal rules above still apply. | Up to $2,000 |
| The adult is at least 2 years older than the minor. | The criminal rules above still apply. | Up to $5,000 |

Does California Have a Romeo and Juliet Law?
California does not have a general Romeo-and-Juliet or close-in-age exception that automatically makes otherwise prohibited intercourse legal. Instead, §261.5 uses the age gap to determine the seriousness of the offense, so people who are close in age can still fall within the statute. When the minor is no more than three years older or younger than the other person, subdivision (b) classifies the violation as a misdemeanor rather than creating an exemption.
Consider an 18-year-old and a 17-year-old as a simple example. The fact that they are only one year apart does not create a statutory exemption under California law, even where the relationship is voluntary. Because the gap is within three years, however, §261.5(b) places the offense in the misdemeanor-only category rather than the more serious categories available for larger age differences.
Can Two Minors Be Charged Under California Law?
Being under 18 does not automatically prevent a person from being treated as the perpetrator under §261.5. California’s 2026 criminal jury instructions note that the fact that a minor can be a victim does not exclude a minor from being charged as a perpetrator under the close-in-age provision. The legal analysis therefore does not simply divide every case into an “adult offender” and a “minor victim.”
That does not mean every relationship between two teenagers results in prosecution. Charging decisions depend on the facts, the applicable statutes, prosecutorial discretion, and juvenile-court rules where relevant. The important legal point is that California’s close-in-age rule affects the level of the §261.5 offense rather than creating a blanket right for minors close in age to engage in intercourse.
Does a Minor’s Agreement Count as Legal Consent?
A minor’s willingness does not make intercourse lawful under §261.5 when the statutory requirements are otherwise met. California’s jury instructions expressly state that the minor’s consent is not a defense to unlawful sexual intercourse, and the statute sets the relevant minority threshold at under 18. This is why a consensual dating relationship and legal capacity to consent are separate questions.
California also has a broader legal definition of consent for sexual-offense cases in which consent is actually at issue. Penal Code §261.6 describes consent as positive cooperation through an exercise of free will, requiring a person to act freely and voluntarily with knowledge of the nature of the act. A current or previous dating or marital relationship does not by itself establish consent to a particular sexual act.
Does the Age-of-Consent Rule Cover More Than Intercourse?
Penal Code §261.5 specifically addresses sexual intercourse, so it should not be treated as a complete catalog of California laws involving sexual conduct with minors. Separate provisions address acts such as oral copulation, sodomy, sexual penetration, lewd conduct with children, solicitation, and other conduct. Several of those laws also use age-based restrictions and may carry penalties very different from those imposed under §261. 5.
Penal Code §288 is especially important when a child is under 14. Section 288(a), for example, makes specified lewd or lascivious conduct involving a child under 14 a felony. The offense is punishable by three, six, or eight years in state prison. Force or other specific circumstances can increase the punishment. Section 288(c)(1) addresses certain conduct involving a 14- or 15-year-old. It applies when the other person is at least 10 years older.
Different statutes cover different acts and age thresholds. California’s general age of consent is 18, but that does not resolve every case. The misdemeanor rules under §261.5 may not apply to touching, oral sex, digital conduct, or other alleged acts. The applicable law can depend on the specific conduct and the ages involved. The exact conduct and statute charged can change the available defenses, sentencing range, and registration consequences.
How Does the Age Difference Affect Criminal Penalties?
When the people are no more than three years apart, §261.5(b) makes unlawful sexual intercourse a misdemeanor. When the minor is more than three years younger than the perpetrator, subdivision (c) permits prosecution as either a misdemeanor or felony and provides for up to one year in county jail when treated as a misdemeanor. California lawyers often call an offense a wobbler when prosecutors can charge it as either a misdemeanor or a felony.
Subdivision (d) creates a more serious category when a person who is 21 or older engages in intercourse with a minor under 16. These categories show why two cases involving a person under 18 can carry very different exposure depending on the exact birthdays of both people.
Civil Penalties Can Apply in Addition to Criminal Charges
Penal Code §261.5 also authorizes civil penalties against an adult who engages in unlawful sexual intercourse with a minor. The maximum amount begins at $2,000 when the minor is less than two years younger, rises to $5,000 when the minor is at least two years younger, and reaches $10,000 when the minor is at least three years younger. An adult over 21 who engages in intercourse with a minor under 16 may face a civil penalty of up to $25,000.
These civil penalties are distinct from the criminal classification of the offense. The district attorney may seek to recover the funds, and the statute specifies how officials must handle any recovered money. As a result, evaluating possible consequences requires looking beyond jail or prison exposure alone.
The 2026 Sex-Offender-Registration Change
California law changed significantly on January 1, 2026, for certain §261.5 offenses. Current Penal Code §290 includes convictions under subdivisions (c) and (d) of §261.5 when the underlying offense occurred on or after January 1, 2026, among offenses that can trigger registration under the Sex Offender Registration Act. Older articles stating that a §261.5 conviction never requires registration can therefore be outdated.
The current statute also contains an important exception. That exception also requires the conviction to be the person’s only offense requiring registration. Even when that exception applies, however, the statute states that a court may still order registration under Penal Code §290.006.
California uses a tiered registration system with statutory minimum periods that can be 10 years, 20 years, or life depending on the offense and classification. Section 290 identifies tier-one registrants as people who must register for qualifying misdemeanors or qualifying felonies that do not qualify as serious or violent felonies and do not place them in a higher tier. Anyone facing an actual charge should have a California criminal-defense lawyer determine whether registration applies to that specific offense date, conviction, age gap, criminal history, and charging statute.
Is Marriage an Exception?
Section 261.5 defines unlawful sexual intercourse as intercourse with a minor who is not the spouse of the perpetrator. A legally valid marriage therefore falls outside this particular statutory definition, although that does not mean marriage eliminates other sexual-offense laws or makes nonconsensual conduct lawful. The exception should be understood narrowly and in the context of the exact statute being considered.
California also places special requirements on marriage involving a person under 18. The California Courts self-help center explains that a minor who wants to marry needs both parental permission and court permission. Because of those additional requirements, the spousal wording in §261.5 should not be mistaken for a broad loophole available to an unmarried couple.
Does Emancipation Change the Age of Consent?
No, emancipation does not automatically give a minor the same legal status as an adult for every purpose. The California Courts self-help center expressly states that someone who has sex with an emancipated minor can still be arrested for statutory rape unless the two people are legally married to each other. An emancipated 16- or 17-year-old therefore does not become 18 for purposes of California’s age-of-consent rules.
Emancipation gives a teenager significant independence in areas such as housing, finances, work, and certain decisions, but California still describes that person as an “emancipated minor.” Other age-based laws continue to apply after emancipation. This distinction matters because legal adulthood for one purpose does not necessarily determine capacity under a different criminal statute.
Can Mistake About the Minor’s Age Be a Defense?
California recognizes a potentially important defense when a defendant reasonably and actually believed the other person was at least 18. CALCRIM No. 1071 instructs that, where sufficient evidence supports the issue, the prosecution must prove beyond a reasonable doubt that the defendant did not reasonably and actually hold that belief. The defense comes from California case law, including People v. Hernandez, and is different from a Romeo-and-Juliet rule.
The defense is highly fact-specific and does not mean that merely asking someone’s age automatically eliminates criminal liability. A court can consider the circumstances relevant to whether the belief was both genuine and reasonable. The same mistake-of-age analysis should also not be assumed to apply automatically to every other offense involving a child, because different statutes and age categories can have different rules.
What Happens When the Child Is Under 14?
Cases involving children under 14 can implicate Penal Code §288 and other serious statutes rather than only the unlawful-intercourse provisions of §261.5. Under §288(a), specified lewd conduct involving a child under 14 is a felony with a three-, six-, or eight-year prison range, while §288(b)(1) provides higher terms when force, violence, duress, menace, or fear is involved. The penalties and defenses can therefore be dramatically different from those in a close-in-age §261.5 case.
California Supreme Court precedent also illustrates why defendants should not assume a reasonable mistake about age works identically for every child-sex offense. In People v. Olsen, the court held that a reasonable mistake about the victim’s age did not provide a defense to the lewd-act offense involving a child under 14 at issue in that case. This is another reason legal advice about “statutory rape” should be tied to the actual statute charged rather than relying on a general age-of-consent summary.
What Should Someone Do if They Are Facing an Age-of-Consent Charge?
A person who has been arrested, contacted by investigators, or accused of an offense involving a minor should speak with a California criminal-defense attorney before making decisions about statements, pleas, or case strategy. The exact ages, birth dates, alleged conduct, date of the offense, communications between the people involved, and statute charged can all materially affect the case. Internet summaries are useful for understanding the basic framework, but they cannot determine whether a defense or registration exception applies to a particular set of facts.
A plea also should not be treated as a simple way to make the issue disappear. A guilty or no-contest plea can create a criminal conviction and may carry consequences beyond the immediate sentence. Readers dealing with an actual case may also find Milsblog’s guide to nolo contendere useful for understanding why plea consequences need careful review. A lawyer familiar with California criminal and sex-offense law can evaluate those consequences before a plea is entered.
The Bottom Line
The age of consent in California is 18, and California does not provide a general Romeo-and-Juliet exemption that makes sexual intercourse legal solely because two people are close in age. The age gap instead changes the potential criminal classification, civil penalties, and, for certain offenses occurring on or after January 1, 2026, possible sex-offender-registration consequences. Marriage, emancipation, mistake of age, and allegations involving children under 14 all require additional legal analysis rather than a simple application of the number 18.
Frequently Asked Questions
The legal age of consent in California is 18, not 16. Penal Code §261.5 defines a minor as anyone under 18 for purposes of unlawful sexual intercourse. A person should not rely on another state’s lower age of consent when evaluating conduct governed by California law.
A 17-year-old is still a minor under §261.5, so the one-year age gap does not create an exemption. Because the people are within three years of each other, the statute places the violation in its misdemeanor category. California therefore treats the close age difference as a factor affecting severity, not as a rule making the intercourse lawful.
California’s age-of-consent statute regulates specified sexual conduct rather than making every dating relationship itself a violation of §261.5. However, sexual intercourse with a person under 18 can trigger §261.5, and other forms of sexual conduct or communication may be governed by separate criminal laws. The legality of a specific situation therefore depends on what actually occurred, not merely on whether the people described themselves as dating.
California has a three-year charging distinction, not a blanket legal exception. Section 261.5(b) makes the offense a misdemeanor when the minor is no more than three years older or younger than the other person. The conduct can still violate the statute even though the age difference is small.
A statement about age does not automatically make otherwise prohibited conduct legal. California does recognize a defense in appropriate §261.5 cases when the defendant actually and reasonably believed the person was at least 18, but whether that standard is satisfied depends on the evidence. Anyone relying on a mistake-of-age defense in a real case should have the facts evaluated by a California attorney because the defense does not operate identically across every offense involving minors.
