AB 701 directs the California Department of Justice, working with the Department of Corrections and Rehabilitation and the Board of State and Community Corrections, to conduct a one‑time, statewide study of solitary confinement in all jails, prisons, and private detention facilities — contingent on appropriation. The bill defines solitary confinement as confinement in a cell or similar space for 17 or more hours per day and spells out detailed data elements the DOJ must collect for each instance occurring during the first nine months of 2026.
The bill requires facilities to report granular information (timing, unit, duration including periods beginning before the study window, stated reasons, demographics including pregnancy/postpartum and LGBT status, conditions of confinement, sanctions, incidents of self‑harm and deaths, and use of force). The DOJ must post monthly interim data publicly and deliver a final report to the Governor and Legislature by November 1, 2026.
At a Glance
What It Does
The bill establishes definitions (cell, out‑of‑cell, meaningful human interaction, solitary confinement at 17+ hours/day) and mandates a one‑time data collection and study of solitary confinement across California detention facilities covering the first nine months of 2026. It compels facilities to supply detailed incident‑level data and requires the DOJ to publish monthly interim datasets and a final report.
Who It Affects
State and county detention operators (CDCR facilities, county jails) and private detention facilities must assemble and submit detailed records; the DOJ, CDCR, and BSCC must coordinate the study and analysis. Researchers, civil‑rights litigators, and advocacy groups will gain access to new, standardized datasets.
Why It Matters
AB 701 creates a statutory, standardized definition of solitary confinement (17+ hours) and builds a single, centralized dataset that could change oversight, policy debates, and litigation by exposing patterns across facilities, demographic disparities, and links between confinement and self‑harm, use of force, and deaths.

What This Bill Actually Does
AB 701 is narrowly focused: it sets a statutory definition of solitary confinement — any confinement in a cell or similarly confined space for 17 or more hours in a day — and then directs the Department of Justice, if the Legislature provides funding, to run a one‑time, systemwide study of how solitary is used in California. The department must do the work in partnership with CDCR and the Board of State and Community Corrections and collect standardized, incident‑level data from every detention facility in the state, including private facilities as defined in the Government Code.
The bill prescribes what data must be gathered for every instance that qualifies as solitary confinement during the study window: start and end times (and projected end dates if confinement continues), the precise facility and unit classification (disciplinary, administrative segregation, protective custody, alternatives, etc.), total consecutive and study‑period durations, and the stated reason for placement. It also requires individual‑level demographic detail — age, gender, race, disability, pregnancy/postpartum status, LGBTQI+ identification, and known health conditions — along with descriptions of the type and frequency of any 'meaningful human interaction' provided.Beyond the placement record, AB 701 forces facilities to document environmental and programmatic conditions: hours of out‑of‑cell time, group versus individual out‑of‑cell time, program hours, cell dimensions, lighting and ventilation, and access to outdoor recreation.
The study separately tracks adverse events tied to confinement: incidents of self‑harm, suicide attempts, suicides (including within 60 days after confinement), deaths and their causes, sanctions that precipitated or accompanied confinement (including loss of visits, commissary, or 'cell shields'), and staff uses of force tied to solitary confinement.On procedure, the bill leaves the reporting cadence to the DOJ (facilities must report with a frequency the department sets), obliges the DOJ to publish interim monthly data on its website, and requires a consolidated final report to the Governor and Legislature by November 1, 2026. The statutory study only takes effect if the Legislature appropriates funds to pay for the data collection and analysis.
The Five Things You Need to Know
The bill defines solitary confinement as being isolated in a cell or non‑group setting for 17 or more hours per day — the statutory threshold that determines which incidents must be reported.
The study covers every qualifying instance during the first nine months of 2026, including confinements that began before that period and projected end dates for ongoing placements.
Facilities must report detailed sanctions data, listing sanctions such as loss of visits, packages, correspondence, phone calls, tablets, cell shields, programs, recreation, commissary, restitution, forfeiture of funds, loss of good time, family reunion program removal, and imposed work tasks.
The DOJ must publish interim datasets monthly and post a final report on its website by November 1, 2026; reporting frequency from facilities is to be set by the DOJ.
The dataset must include adverse‑event tracking tied to solitary confinement: self‑harm, suicide attempts, suicides (including within 60 days post‑confinement), deaths with cause, and staff uses of force broken down by facility and unit.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definitions — cell, out‑of‑cell, meaningful interaction, solitary confinement
This section builds the bill’s technical foundation by defining key terms that determine scope and coverage. 'Cell' is broad (any intended sleeping area or any non‑shared space not conducive to group interaction); 'out‑of‑cell' and 'meaningful human interaction' are described in human‑centered terms rather than purely operational metrics, which creates interpretive questions for implementers. The statutory solitary threshold — 17 hours per day — is decisive: it creates a binary rule for reporting eligibility and will drive which incidents facilities classify for the study.
Authority and collaboration — DOJ to conduct one‑time statewide study
This subsection assigns the Department of Justice primary responsibility for the study and requires collaboration with CDCR and the Board of State and Community Corrections. Critically, the obligation is contingent on a legislative appropriation, meaning the study only moves forward if funding is provided. The collaboration requirement signals that the bill expects operational input and data access from the agencies that run and oversee facilities.
Incident‑level placement data required
This subsection lists the placement‑level details facilities must supply: timestamps, facility and unit identifiers and classification, total consecutive duration (including pre‑study starts), stated basis for placement, and a broad set of demographic markers. These fields are precise enough to support longitudinal and cross‑facility comparisons, but they will require facilities to pull or create person‑level records tied to specific incidents, which has IT, privacy, and staffing implications.
Conditions, sanctions, adverse events, and use‑of‑force data
This part expands the dataset to include environmental conditions (cell size, lighting, ventilation), programmatic measures (out‑of‑cell hours, group programming), sanction inventories, and adverse event tallies (self‑harm, suicides within 60 days, deaths, and uses of force). The combination of programmatic and clinical outcome measures allows researchers to link conditions to harms, but it also raises data‑quality challenges because facilities currently vary in how they record such events.
Reporting mechanics, public posting, and deadline
Facilities must report the required data to the DOJ at a frequency the department sets; the bill leaves that cadence to DOJ rulemaking or administrative guidance. The DOJ must provide monthly interim reports to the Legislature and publish interim data publicly, and it must deliver a final report and publish it by November 1, 2026. The statute also requires compliance with Government Code Section 9795 for report formatting, which could affect how narrative analysis and data are presented.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Incarcerated people subject to solitary confinement — the dataset increases transparency about who is placed in solitary, for how long, and under what conditions, which can inform advocacy, medical review, and parole or reentry planning.
- Researchers and public‑health analysts — the mandated demographic and outcome fields (including pregnancy/postpartum, disability, and LGBTQIA+ status) will enable studies of disparate impacts and mental‑health outcomes linked to confinement.
- Civil‑rights and public‑interest lawyers — standardized, facility‑level evidence could support litigation or consent‑decree arguments by revealing patterns, durations, and associations with self‑harm or deaths.
- Policymakers and legislators — access to cross‑system, incident‑level data will permit evidence‑based policy choices about limits, alternatives, and funding priorities for mental‑health services and programming.
- Community oversight bodies and advocacy organizations — monthly interim public posting creates near‑real‑time visibility into practices inside facilities, strengthening external oversight.
Who Bears the Cost
- County jails, state prisons, and private detention facilities — facilities must extract incident‑level, person‑level, and environmental data that many do not currently capture in a standardized way, imposing administrative, IT, and staff costs.
- California Department of Justice, CDCR, and BSCC — the DOJ is tasked with collecting, validating, analyzing, and publishing a large dataset and narrative report, which requires analytic resources and coordination capacity; CDCR and BSCC must assign staff time for cooperation.
- Taxpayers/government budgets — because the study proceeds only 'upon appropriation,' the Legislature must allocate funds to cover the collection and analysis costs, creating a new budgetary line for oversight work.
- Facility staff and clinicians — increased documentation and possible scrutiny could impose additional recordkeeping duties and expose staff decisions to review or litigation, potentially affecting operations.
Key Issues
The Core Tension
The central dilemma is between transparency and comparability on one hand — demanding rich, incident‑level data to expose harms and disparities — and privacy, operational feasibility, and the risk of perverse incentives on the other; pushing for exhaustive, public data can improve oversight but also burdens facilities, raises confidentiality risks, and may change behavior in ways that obscure rather than clarify true practice.
AB 701 creates a valuable, centralized dataset, but implementation will expose several thorny trade‑offs. First, the bill’s operational definitions lean on qualitative terms — notably 'meaningful human interaction' — that facilities will have to operationalize to produce comparable data.
Without clear, measurable criteria, facilities may report inconsistent counts of out‑of‑cell time or group interaction, limiting comparability. Second, the law requires highly sensitive individual‑level data (health conditions, pregnancy/postpartum status, sexual orientation/gender identity).
Collecting and publicly posting interim datasets raises privacy and confidentiality risks that will need mitigation through redaction, aggregation thresholds, or secure data protocols.
Third, the 17‑hour threshold creates a hard reporting cut‑off that could incentivize short‑interval confinement practices designed to avoid classification as 'solitary' even where the psychological effects are similar. Fourth, the bill leaves reporting frequency to the DOJ, which offers necessary administrative flexibility but also creates implementation uncertainty for facilities that must budget staff and IT time.
Finally, because the study window is the first nine months of 2026, the dataset may capture operational anomalies (policy changes, staffing disruptions, or pandemic remnants) that complicate efforts to generalize findings beyond that window.
