PC 457 Arson Registration: Duration, Updates, and Penalties

California Penal Code Section 457.1 requires anyone convicted of arson or a related fire offense to register in person with local law enforcement, provide identifying information and fingerprints, and keep that registration current whenever they move. For almost everyone covered today, PC 457.1 arson registration is a lifetime obligation, and the only way out is a certificate of rehabilitation or, for misdemeanor cases, an expungement under Penal Code Section 1203.4.¹

Who Has to Register

Registration is mandatory after a conviction under any of four Penal Code sections:

Section 451, arson of a structure, forest land, or property.
Section 451.5, aggravated arson.
Section 453, possessing or manufacturing flammable or incendiary materials with intent to set a fire.²
Section 455, attempted arson.

A conviction in another state or in federal court for an equivalent offense also triggers the duty if you move to California.¹

A judge can also order registration for a conviction outside those four sections. That happens at sentencing when the court finds the person showed a pattern of compulsive fire-setting or used an incendiary device to cause destruction. The sentencing record itself is the official determination.¹

How Long the Obligation Lasts

The duration depends on when the case was resolved and whether it went through adult or juvenile court.

Adult convictions on or after November 30, 1994: registration is for life.
Juvenile adjudications on or after January 1, 1993: registration continues until the person turns 25 or has their juvenile records sealed, whichever comes first. When either happens, registration records held by the Department of Justice and local agencies are destroyed.
Convictions between January 1, 1985 and November 29, 1994: a five-year obligation, running from release from confinement or from sentencing if no confinement was imposed, and only if the sentencing judge specifically ordered registration.¹

For the overwhelming majority of current registrants, the obligation is permanent unless legal relief is granted.

Where and When to Register

You have 14 days to complete your initial registration after being released from custody or after arriving in a new city, county, or campus area. The agency depends on where you live:

Inside a city, register with the chief of police.
In an unincorporated area, or a city with no police department, register with the county sheriff.
If you live on or are located on a University of California, California State University, or community college campus, you must also register with the campus police chief, in addition to the city or county agency.¹

The campus requirement is often missed. It’s a separate step on top of local registration, and missing it is treated as its own violation.

If you have no residence, the duty still applies. You register where you are physically located, within the same 14-day window, and you update whenever you move to a new city or county.¹

What You Submit at Registration

At the appointment you provide a written statement with your legal name, any aliases, your date of birth, and your current address. Law enforcement takes a full set of fingerprints and a current photograph for the state database.³

You sign the form under penalty of perjury, confirming the information is accurate and that you understand your continuing duties. The officer must give you a copy of the completed paperwork. Keep that copy. It’s your proof of compliance if a dispute ever arises.¹

Updating After a Move

A move has two separate deadlines, and mixing them up is one of the most common ways people fall out of compliance.

Within 10 days of leaving your old address, notify the law enforcement agency where you are currently registered, in writing, that you have moved, and give them your new address.¹

Within 14 days of arriving at your new location, complete a fresh in-person registration with the agency that covers the new address. The Department of Justice forwards your file, but appearing in person is still on you.⁴

One thing the arson registry does not require: periodic annual check-ins. Unlike California’s sex offender registry, PC 457.1 ties your updates to the initial registration and to any change in address or location, not to a calendar.

Penalties for Failing to Register

Every violation of any provision of Section 457.1 is a misdemeanor.¹

Consequences escalate for people whose underlying conviction was under Section 451, 451.5, 453, or 455. A willful violation in that situation carries a mandatory minimum of 90 days in county jail and at least one year of probation, with a maximum of one year in jail. The judge cannot waive or reduce the 90-day minimum.¹

Getting Off the Registry

Lifetime does not mean permanent in every case. The statute offers two routes out.

The first is a certificate of rehabilitation under Penal Code Sections 4852.01 and following. Any person required to register can petition. If granted, the certificate ends the registration duty. A future arson conviction would restart the obligation from scratch.¹

The second applies only to misdemeanor convictions. Relief under Penal Code Section 1203.4, commonly called expungement, ends the registration obligation for a misdemeanor case.³

Neither route is quick. A certificate of rehabilitation requires a waiting period after you complete your sentence and a showing of rehabilitation that satisfies the court. For someone staring at a lifetime obligation, it’s a path worth discussing with a lawyer who handles post-conviction relief.
