California Penal Code 261.5: Penalties, Fines, and Registration

California statutory rape penalties under Penal Code 261.5 run from a misdemeanor with up to one year in county jail to a felony carrying up to four years, and the age gap between the two people controls which end of that range applies. On top of the criminal sentence, a conviction can bring fines, civil penalties collected by the district attorney, and in some cases sex offender registration.

Penalty Tiers Based on Age Gap

Penal Code 261.5 splits the offense into three tiers. The gap between the defendant’s age and the minor’s age decides which tier applies and how severe the exposure gets.

Three Years Apart or Less

When the two people are within three years of each other in age, the charge is always a misdemeanor.¹ A 19-year-old with a 17-year-old partner falls here. The maximum punishment is up to one year in county jail. The conduct is still a crime; the statute just caps the severity.

More Than Three Years Apart

Once the age gap exceeds three years, the offense becomes a wobbler, meaning the prosecutor can file it as either a misdemeanor or a felony.¹ As a misdemeanor, the ceiling stays at one year in county jail. As a felony, the sentence is 16 months, two years, or three years in county jail under California’s realignment sentencing.² The judge chooses from that triad based on the facts of the case.

Defendant 21 or Older with a Minor Under 16

The top tier applies when the defendant is at least 21 and the minor is under 16. This is still a wobbler, not an automatic felony, but the felony prison range rises to two, three, or four years.¹ Prosecutors almost always file this tier as a felony given the age gap involved.

Criminal Fines

Penal Code 261.5 does not set its own fine amounts, so California’s general fine statutes fill in. A misdemeanor conviction carries a fine of up to $1,000.³ A felony conviction carries a maximum fine of $10,000.⁴

The statute also authorizes an added $70 assessment on top of any other punishment, directed to a fund related to victim services, and the judge must consider the defendant’s ability to pay before ordering it.¹

Civil Penalties

Separate from the criminal fines, the district attorney can pursue civil penalties against any adult convicted under this statute. The amounts scale with the age gap:

Less than two years older than the minor: 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 These civil penalties apply only to adult defendants, not to 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 carves out an explicit exception: a person convicted under subdivision (c) or (d) does not have to register as long as they were no more than 10 years older than the minor and the conviction is their only qualifying sex offense.⁵

Even where registration is not mandatory, a judge can still order it on a case-by-case basis under Penal Code 290.006. Courts typically consider whether the offense was committed out of sexual compulsion or for purposes of sexual gratification when deciding whether to impose discretionary registration.⁵ This is more common in felony cases, but the option exists regardless of how the charge is classified.

Collateral Consequences

The sentence imposed in court is not the end of the exposure. Several consequences can follow a defendant long after any jail time or probation ends.

Firearm Restrictions

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 carry prison terms of up to three or four years, a felony conviction permanently disqualifies the defendant from legal gun ownership under federal law.

Immigration Consequences

For non-citizens, a felony conviction creates serious immigration risk. Federal immigration law classifies “sexual abuse of a minor” as an aggravated felony, which makes a person deportable and generally bars eligibility for most forms of immigration relief, including asylum and cancellation of removal.⁷ Whether a particular 261.5 conviction qualifies depends on the specific facts and the age gap, but the risk is severe enough that any non-citizen facing this charge should consult an immigration attorney alongside criminal defense counsel.

Employment and Professional Licensing

Both misdemeanor and felony convictions appear on criminal background checks and can affect employment, particularly in fields involving children, healthcare, education, and law enforcement. California professional licensing boards routinely review criminal histories, and a sex-related conviction can result in denial or revocation of licenses even when the underlying charge is a misdemeanor.

The Reasonable Mistake of Age Defense

California is one of the few states that recognizes a reasonable mistake of age defense to this charge. The California Supreme Court established the defense in People v. Hernandez, holding that a defendant who genuinely and reasonably believed the minor was 18 or older has a valid defense.

Succeeding on this defense takes more than a bare claim of ignorance. The defendant must have actually believed the minor was old enough, and that belief must have been objectively reasonable under the circumstances. Evidence that the minor lied about their age, presented a fake ID, or was encountered in an adults-only setting strengthens the defense. Vague assertions that the minor “looked older” rarely hold up alone. When the defendant produces enough evidence to make the belief plausible, the prosecution must prove beyond a reasonable doubt that the defendant did not hold that reasonable, good-faith belief. This defense can take the penalties above off the table entirely, and it distinguishes California from states that treat statutory rape as a strict-liability offense.
