California Penal Code § 290 PC requires you to register as a sex offender with local authorities if you get convicted of certain crimes, primarily sex offenses. Registration must be renewed every five years and whenever you change your residence.
Failure to register as a sex offender in California is typically charged as a misdemeanor if the underlying sex crime was a misdemeanor, or as a felony if the underlying sex crime was a felony:

Examples of 290 PC violations are:
- A former high school teacher who was convicted of statutory rape, for having sex with a teenage student, moves to a new city and decides not to register her new address with the authorities.
- A man who was convicted of rape after a date rape incident in college stops registering annually because he wants to put that chapter of his life behind him.
- A former gang member who was convicted of human trafficking decides not to register after a move so that his new neighbors will not mistakenly think he is a pedophile.

1. Elements of 290 PC
You are classified as a sex offender if you get convicted of any sex crime listed in 290 PC. The purpose of registering as a sex offender is so police can more readily track your whereabouts.
For you to be convicted of failing to register as a sex offender under 290 PC, California prosecutors must prove beyond a reasonable doubt the following four elements of California Jury Instruction “CALCRIM” 1170:
- You were previously convicted of a California sex crime for which registration was required under Penal Code 290c PC,
- You resided in California,
- You knew you had a duty to register as a sex offender, and
- You willfully failed to register or update your registration with the sheriff’s office.1
These elements are discussed in detail below.
“Residence” Meaning
“Residence” means wherever you regularly reside. This includes a shelter or structure that can be located by a street address, including recreational and other vehicles.
Note you still have to register if you are a transient and therefore have no residence. You would just tell police your general whereabouts.2
“Knowledge” Meaning
To be convicted of failure to register as a sex offender, you must have actual knowledge of the duty to register as a sex offender.7 You are typically notified of this duty when you are released from jail or prison.3
Merely forgetting to register is not a defense.9 As one California court has stated:
“Although forgetfulness may temporarily or momentarily negate the immediate awareness that one must undertake a given action at a given time, it does not alter or affect the underlying knowledge that such action is required.”4
However, the court also stated that mental weakness might be a defense to a 290 PC charge.5 This may include if you are forgetful due to Alzheimer’s or senility.
“Willfulness” Meaning
You fail to register “willfully” when you do it willingly or on purpose. It is not necessary that you intended to break the law.6
“Register” Meaning
Once you are released from jail or prison, you have five business days to register your residence with local law enforcement. Furthermore, this registration has to be renewed:
- every year within five working days of your birthday, and
- every time you move to a new address, and
- every 30 days if you are a transient.
How long you must register depends on your tier level:
- tier three offenders have to register for life,
- tier two offenders must register for a minimum of 20 years, and
- tier one offenders must register for a minimum of 10 years.7

It is a California crime to violate the sex offender registration requirements.
2. Defenses
Here at Shouse Law Group, we have represented literally thousands of people charged with failing to register as a sex offender in California. In our experience, the following three defenses have proven very effective with prosecutors, judges, and juries at getting 290 PC charges reduced or dismissed.
- There was no willful act. Perhaps you were in the hospital or temporarily incapacitated at the time you had to register. As long as your failure to register was not deliberate, criminal charges should not stand.
- The authorities lost your registration information. The government makes clerical errors all the time. As long as you did everything you were supposed to do, you should not be held liable for the police’s mistakes.
- You did not know you had to register. Perhaps the authorities failed to notify you of your duty to register, or perhaps there was a language barrier that prevented you from understanding your duties. As long as there is no record of you being informed of your duties, the D.A. may agree to drop the charge.

A violation of PC 290 can result in a fine and/or jail time.
3. Penalties
The penalties for failing to register as a sex offender in violation of California Penal Code 290 PC depend on whether the original sex offense you were convicted of was a misdemeanor or a felony.
Failure to register following a misdemeanor conviction is a misdemeanor. The possible penalties include:
- misdemeanor (or summary probation),
- imprisonment in the county jail for up to 1 year, and/or
- a maximum fine of $1,000.
If you were convicted of a felony sex crime, or if you have a prior conviction of violating 290 PC, then failure to register is a felony. The possible penalties include:
- felony (or formal) probation,
- imprisonment in state prison for 16 months, 2 years, or 3 years, and/or
- a maximum fine of $10,000.8
4. Immigration Consequences
A 290 PC conviction, on its own, will generally have no negative immigration consequences for non-citizens. However, the underlying sex crime likely is deportable.
If you are a non-citizen accused of any crime, it is vital you contact an attorney to try to get the charge dismissed or reduced to a non-deportable offense. Otherwise, you may be thrown out of the U.S. after your sentence ends.9
5. Expungements
As a basic rule, 1203.4 PC allows you to expunge your 290 PC conviction as long as you successfully complete probation or jail. Expunged criminal records do not need to be revealed to potential employers.10
Note, though, that an expungement of a 290 PC conviction does not relieve you of the obligation to continue registering as a sex offender.

One may lose access to gun ownership and/or possession if convicted as a felon in California.
6. Gun Rights
A felony conviction of failing to register as a sex offender in California will strip you of your gun rights for life. A misdemeanor conviction should not affect your gun rights; however, the underlying sex crime may have already stripped you of your gun rights.11
7. Related Crimes
Habitual Sex Offender
California Penal Code 667.71 PC criminalizes repeat sexual offenders. 667.71 PC applies to sex crimes like:
A habitual sexual offender is guilty of a felony. The crime is punishable by imprisonment in the state prison for 25 years to life. Probation is generally prohibited.12
Use of a Firearm in the Commission of a Sex Crime
California Penal Code 12022.3 PC creates a firearm sentencing enhancement for anyone who uses or possesses a gun during the commission of certain sex offenses. A “certain sex offense” includes (but is not limited to):
- rape,
- spousal rape, or
- sodomy.
The additional and consecutive sentence for violating 12022.3 PC is:
- 3, 4, or 10 years for using a gun or a deadly weapon or
- 1, 2, or 5 years for being armed with a firearm or a deadly weapon.13
Lewd Acts with a Minor Child
California Penal Code 288 PC makes it a crime to commit a “lewd act” with a minor child.27 This is:
- touching a child for sexual purposes or
- causing a child to touch themself or someone else for a sexual purpose.
The specific penalties for violating 288 PC will vary depending on:
- the age of the child,
- whether the lewd act was accomplished by force, violence, duress, or threats,
- whether there was a pattern of lewd acts, and
- in some cases, your age.14
