California AB 2570 revises who must register and how sex-offender tiers are set

Updates to the Sex Offender Registration Act add campus reporting, risk-based tiering, retroactive offense language, and a 24‑month tier-assignment window for the DOJ.

The Brief

AB 2570 replaces and reorganizes Section 290 of the California Penal Code to recast who must register as a sex offender, how long they must remain on the registry, and how the Department of Justice assigns tier status. The bill requires in-state registration for people living, working, or attending school in California, explicitly adds campus police and specific higher‑education campuses to the registration locations, and ties tier placement to enumerated offenses, statutory seriousness definitions, and a static risk instrument (SARATSO).

The bill matters for law enforcement, colleges, and anyone who already is — or may become — a registrant. It expands the mechanics for classifying registrants into 10-, 20‑year, or lifetime categories, creates a temporary “tier‑to‑be‑determined” status with a 24‑month DOJ window to finalize placement, and imposes particular tolling and extension rules that increase registration periods for failures to register.

Those details will change operational workloads for DOJ, local police, and campus authorities and will materially affect the duration and certainty of registrants’ obligations.

At a Glance

What It Does

The bill restates the Sex Offender Registration Act, requires registration within five working days of moving into or changing residence (including specified campuses), and defines tier one (10 years), tier two (20 years), and tier three (lifetime) registrants based on listed offenses, statutory serious‑felony tests, and a static risk score (SARATSO).

Who It Affects

Current and future registrants (including those attending or living on UC, CSU, and community college campuses), the Department of Justice, local law enforcement and campus police, and institutions that must track on‑campus residents. Defense counsel and probation officers will also face new classification mechanics.

Why It Matters

The bill shifts more of the tiering decision to a combination of offense lists and a risk instrument, authorizes a temporary tier status while DOJ decides, and imposes specific penalties and extensions that lengthen registration periods — producing administrative consequences and potential legal questions about retroactivity and procedural safeguards.

What This Bill Actually Does

AB 2570 reworks Section 290 to specify who must register and where they must register while in California. It keeps the core duty — register with the local chief of police or sheriff — but clarifies that people who live on, work at, or attend campuses of the University of California, California State University, or community colleges must also register with the appropriate campus police when they reside on campus or in campus facilities.

The bill sets a tight initial deadline: register within five working days of entering or changing a California residence, campus residence, or temporary residence.

The bill defines three registration tiers tied to the length of the registration obligation: tier one is a minimum of 10 years, tier two is 20 years, and tier three is life. Which tier applies depends on a mix of factors: whether the underlying conviction appears on an enumerated list of offenses, whether the offense is a serious or violent felony under existing statutes, whether the individual has subsequent qualifying convictions, special status (for example, commitment as a sexually violent predator), and the individual’s static risk level as measured by SARATSO.

AB 2570 explicitly allows the Department of Justice to place a person initially into a temporary “tier‑to‑be‑determined” category when the correct tier cannot be immediately ascertained, but requires DOJ to reach a final tier decision within 24 months.The bill also governs out‑of‑state convictions and registrations: if someone’s duty to register stems from another jurisdiction, the DOJ is to map that person to an equivalent California tier; absent an equivalent California offense, the default is tier two unless certain high‑risk or commitment criteria apply that elevate the person to tier three. AB 2570 further clarifies how the minimum registration clock runs and when it is tolled: the clock starts on release from custody, is tolled during subsequent custody or civil commitment, and is extended by statutory penalties — one additional year for each misdemeanor failure to register and three years for each felony failure to register — regardless of time actually served for that failing‑to‑register conviction.Finally, the bill preserves an exception for juvenile court wards except where a separate provision requires registration, and it contains date thresholds for applying registration to certain offenses (for example, some provisions trigger only for offenses occurring on or after January 1, 2026, or for convictions on or after January 1, 2025).

Collectively, these mechanics shift more of the registration outcome onto offense lists and a specified risk assessment process while adding administrative steps and extensions that change the practical length and certainty of registration obligations.

The Five Things You Need to Know

1

The bill requires registration within five working days after arriving at or changing any residence in California, and it explicitly requires registration with campus police if a registrant resides on UC, CSU, or community college campuses.

2

Tier durations are fixed to 10 years (tier one), 20 years (tier two), and life (tier three), with tier three triggered not only by listed violent offenses but also by a 'well above average' SARATSO risk score or civil commitment as a sexually violent predator.

3

If DOJ cannot immediately assign a tier, it may place the person in a 'tier‑to‑be‑determined' category; DOJ must finalize the tier within 24 months, and the registrant receives credit toward the minimum period for time spent in the temporary tier.

4

An out‑of‑state conviction or out‑of‑state registration will be mapped to an equivalent California tier; where no equivalent exists, the default is tier two unless SARATSO, subsequent convictions, or prior civil commitment justify tier three.

5

The statute tolls the minimum registration period during incarceration and civil commitment and separately extends the required minimum by one year for each misdemeanor failure to register and by three years for each felony failure to register, regardless of actual time served for that failing offense.

Section-by-Section Breakdown

Every bill we cover gets an analysis of its key sections. Expand all ↓

Subdivision (a)

Formal name and scope: Sex Offender Registration Act

This opening provision restates that Sections 290–290.024 are the Sex Offender Registration Act and anchors subsequent cross‑references. It’s procedural, but it matters because it signals a consolidated rework of Section 290 and frames any interpretive guidance or administrative rules that flow from the revised section language.

Subdivision (b)

Where and when to register, including campus requirements

Subdivision (b) restates the duty to register with local law enforcement and adds an explicit requirement to register with campus police when the registrant resides on UC, CSU, or community college campuses or facilities. It fixes a five‑working‑day deadline to register after coming into or changing residence in any California jurisdiction or campus. Practically, this expands reporting endpoints for people with campus ties and creates a new operational obligation for campus police and housing offices to intake and monitor registrants.

Subdivision (c)

Enumerated offenses and special age/date carveouts

Subdivision (c) is a long enumeration of which convictions create a duty to register, including many sexual and related violent offenses. It also creates discrete carveouts based on the ages of the parties and dates: for certain offenses (like specified subdivisions of Section 261.5 and Section 647(l)(2)) the duty to register depends on whether the offense occurred or was convicted on or after specified calendar dates and on an age‑gap test (not more than 10 years). These date and age triggers will require records checks to determine applicability, and they create situations where otherwise similar convictions produce different registration outcomes depending on timing and the birthdates involved.

Subdivision (d) and (d)(1)-(3)

Tier definitions and lifetime triggers

Subdivision (d) defines the three registration tiers and the criteria that place a person in each. Tier one covers certain misdemeanors and less serious felonies (10 years). Tier two covers specified serious felonies or repeat convictions (20 years). Tier three mandates lifetime registration for a range of high‑severity convictions, subsequent violent‑felony convictions, civil commitment as a sexually violent predator, very high SARATSO scores, habitual offender status, and other enumerated circumstances. This is the mechanical backbone: offenses, prior convictions, commitment status, statutory 'serious or violent' labels, and SARATSO outcomes all feed the tier decision.

Subdivision (d)(4)-(5)

How out‑of‑state convictions and temporary tiering work

These subsections instruct DOJ to map out‑of‑state convictions or registrations to California equivalents. If there is no close equivalent, the default is tier two unless an individual meets specified markers (e.g., SARATSO 'well above average', subsequent similar convictions, or prior civil commitment) that elevate them to tier three. Subdivision (d)(5) permits DOJ to place someone in a 'tier‑to‑be‑determined' status when the correct tier cannot be immediately ascertained, requires continued registration during that period, and obligates DOJ to complete the tier assignment within 24 months—while crediting the registrant for time spent in the temporary status.

Subdivision (e)

When the registration clock runs, tolling, and extensions for failing to register

Subdivision (e) fixes the start of the minimum registration period at release from custody, placement, or commitment and provides that the clock is tolled during subsequent incarceration or civil commitment but not by arrests without conviction. Importantly, the section increases the minimum period for each failure to register: add one year per misdemeanor failure and three years per felony failure, regardless of actual custody time served for those failures. It also specifies that a later conviction requiring registration restarts or changes the applicable tier and clock, with the highest applicable tier governing.

Subdivision (f)

Juvenile‑court ward exception

Subdivision (f) preserves the general rule that wards of the juvenile court are not required to register under this section, except where another statutory provision (Section 290.008) specifically requires registration. This keeps juvenile‑status carveouts in place while leaving open narrowly focused juvenile registration mandates elsewhere.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Local law enforcement and DOJ — the bill gives clearer statutory mechanics for tiering, a defined window to resolve ambiguous cases, and a risk instrument (SARATSO) to justify higher classifications, simplifying decision criteria for prosecutions and community‑safety planning.
  • Campus police and higher‑education administrators — AB 2570 explicitly brings on‑campus residency under the registration duty, improving authorities’ legal footing to track and limit campus access and housing decisions.
  • Victims and public‑safety planners — longer and clearer minimum registration periods (including extensions for failures to register) increase predictability about who will remain on registries and for how long, which can inform notification and monitoring strategies.

Who Bears the Cost

  • Registrants and their families — more individuals will have explicit campus reporting duties and longer or life‑long obligations in many cases; the statute also makes lapses in registration more punitive by adding set extensions to minimum periods.
  • Department of Justice — DOJ must map out‑of‑state convictions to California equivalents, operate SARATSO assessments, manage a tier‑to‑be‑determined category, and complete tiering decisions within 24 months, increasing administrative, assessment, and appeals workload.
  • Local police and campus law enforcement — agencies will intake more registration events (including campus residences), maintain ongoing monitoring, and absorb compliance and verification duties without additional funding in the text.
  • Defense counsel and public defenders — lawyers will spend more resources litigating tier assignments, equivalence of out‑of‑state offenses, SARATSO results, and retroactivity or date‑based carveouts, raising defense costs and court time.

Key Issues

The Core Tension

The bill tries to strengthen community protection by combining offense lists, statutory seriousness tests, and a static risk instrument to lock registrants into predictable minimums, but that approach collides with concerns about procedural fairness and collateral consequences: it increases administrative predictability and potential public safety at the cost of expanding lifetime obligations, amplifying the effect of minor compliance lapses, and relying on risk tools and retroactive mapping that may be hard to challenge or adjust in individual cases.

AB 2570 packs multiple implementation and legal tensions into a single statutory redesign. First, the long list of enumerated offenses and the inclusion of date and age thresholds (for example, references to convictions "since July 1, 1944" and different effective dates for select offenses) create record‑checking complexity: administrators and courts will need to reconcile conviction dates, prior statutes, and birthdates to determine registration duties and tier placement.

Second, the bill vests substantial weight in SARATSO, a static actuarial instrument; reliance on a single risk tool raises questions about transparency, validation across populations, the availability of meaningful appeals or re‑assessments, and how updates to the tool will interact with fixed statutory outcomes (such as mandatory lifetime registration).

Operationally, the 'tier‑to‑be‑determined' category provides a practical stopgap but also permits up to two years of uncertainty while the registrant continues to submit to all reporting obligations; the statute credits time served in that limbo toward the minimum period, but the delay could hinder release planning, housing, or employment until the final tier is set. The mapping of out‑of‑state convictions to California tiers and the default to tier two where there is no equivalent can overclassify individuals whose foreign convictions would not trigger similar consequences under California law.

Finally, extensions for failures to register are automatic and additive, which creates a disproportionate effect in borderline compliance cases: short, inadvertent lapses or administrative failures can extend registration by years, irrespective of whether the registrant served any new custodial time for the failing conduct.
