California Penal Code 261.5: Statutory Rape Penalties and Defenses

California statutory rape penalties under Penal Code 261.5 run from a misdemeanor carrying up to one year in county jail to a felony carrying up to four years, and the age gap between the two people involved is what decides where a case lands on that scale. The minor’s willingness does not matter. Anyone under 18 is treated by California law as legally unable to consent, so the crime turns on ages and marital status, not on what the minor agreed to.¹

How the Age Gap Sets the Penalty

The statute creates three tiers. Each raises the ceiling on what a court can impose.

Three Years or Less Apart

When the defendant and the minor are within three years of each other in age, the offense is a misdemeanor, full stop.¹ A 19-year-old with a 17-year-old, or two minors close in age, both fall here. The maximum is one year in county jail. The statute can technically apply even when both people are minors, since the age-gap tier looks only at the difference, not at whether either party is an adult.

More Than Three Years Apart

Once the defendant is more than three years older, the charge becomes a wobbler: the prosecutor can file it as a misdemeanor or a felony.¹ A misdemeanor still tops out at one year in county jail. A felony carries 16 months, two years, or three years in county jail, with the judge choosing from that triad based on the circumstances.²

Defendant 21 or Older, Minor Under 16

The highest tier applies when the defendant is at least 21 and the minor is under 16. It remains a wobbler on paper, but the felony range climbs to two, three, or four years.¹ Prosecutors typically file this tier as a felony, though the choice stays with them.

Fines

Penal Code 261.5 does not set its own fine schedule. The general fine statutes fill in. A misdemeanor conviction can carry a fine of up to $1,000.³ A felony conviction can carry up to $10,000.⁴

On top of that, the statute authorizes an additional $70 fine directed to a victim services fund. The judge must weigh the defendant’s ability to pay before imposing it.¹

Civil Penalties

The district attorney can also pursue civil penalties against any adult convicted under the statute. These scale with the age gap:

Less than two years older: up to $2,000
At least two years older: up to $5,000
At least three years older: up to $10,000
21 or older with a minor under 16: up to $25,000

Money collected goes to the Underage Pregnancy Prevention Fund after the county recovers its prosecution costs.¹ Civil penalties reach adult defendants only, not minors charged under the statute.

Sex Offender Registration

A conviction under Penal Code 261.5 does not automatically require sex offender registration. California’s registration law explicitly exempts a person convicted under subdivision (c) or (d) as long as the defendant was no more than 10 years older than the minor and this is the only qualifying sex offense on record.⁵

A judge can still order discretionary registration under Penal Code 290.006. Courts weighing that option typically look at whether the offense was committed out of sexual compulsion or for the purpose of sexual gratification.⁵ Discretionary registration comes up more often in felony cases, but the tool exists regardless of how the charge is classified.

Mistake of Age Defense

California is one of the few states that recognizes a reasonable mistake of age defense to statutory rape. The California Supreme Court established it in People v. Hernandez, reasoning that a genuine and reasonable belief the minor was 18 or older negates the mental state the crime requires.

Two things have to be shown: that the defendant actually believed the minor was old enough, and that the belief was objectively reasonable. Evidence like a fake ID, the minor lying about their age, or an encounter in an adults-only setting can support the defense. A vague “she looked older” usually does not. Where the defense applies, no penalties attach because there is no conviction.

Consequences Beyond the Sentence

The sentence itself is not the end of what a conviction costs.

Firearms

A felony conviction under Penal Code 261.5 triggers a lifetime federal ban on possessing firearms or ammunition under 18 U.S.C. § 922(g), which applies to anyone convicted of a crime punishable by more than one year of imprisonment.⁶ Because the felony tiers here carry three- and four-year exposures, a felony conviction permanently disqualifies the defendant from legal gun ownership under federal law.

Immigration

For non-citizens, the risk is severe. Federal immigration law treats “sexual abuse of a minor” as an aggravated felony, making the person deportable and generally barring most forms of relief, including asylum and cancellation of removal.⁷ Whether a specific Penal Code 261.5 conviction qualifies depends on the facts and the age gap, but the exposure is serious enough that any non-citizen facing this charge should retain an immigration attorney alongside their criminal defense lawyer.

Employment and Licensing

Both misdemeanor and felony convictions appear on background checks. They can affect work involving children, healthcare, education, and law enforcement. California licensing boards review criminal histories as a matter of course, and a sex-related conviction can lead to denial or revocation of a professional license even when the underlying charge was a misdemeanor.
