LEGISLATIVE COUNSEL'S DIGEST
AB 1140, as amended, Connolly. Single-Occupancy Cell Pilot Program.
Existing law establishes the Department of Corrections and Rehabilitation and sets forth its powers and duties regarding the administration of correctional facilities and the care and custody of inmates. Existing law vests in the Secretary of the Department of Corrections and Rehabilitation the supervision, management, and control of the state prisons, and the responsibility for the care, custody, treatment, training, discipline, and employment of persons confined in the state prisons.
This bill, the Single-Occupancy Cell Pilot Program of 2026, would require the Secretary of the Department of Corrections and Rehabilitation to develop and implement a pilot program to house people who are incarcerated at 4 adult prison facilities in single-occupancy cells by January 1, 2027. The bill would require the secretary to select the 4 facilities and establish criteria to determine who will be housed in single-occupancy cells. The bill would require the pilot program to apply to 10% of the population housed at each of the 4 facilities. The bill would require that participation in the program be voluntary, as specified. The bill would require the secretary, by March 15, 2028, to transmit a publicly available report to the Governor and the Legislature detailing specified information pertaining to the pilot program, including the number of incarcerated persons housed in single-cell occupancy cells under the pilot program and participating in education assignments by facility, as specified.
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) It is the intent of the Legislature that the California corrections system promote, to the best extent, increased public safety by reducing recidivism through community-based corrections programs and evidence-based practice.
(b) (1) To properly be able to engage in rehabilitative programming offered by the Department of Corrections and Rehabilitation, incarcerated persons must be able to sleep without fear of physical harm.
(2) A study examining 568 male prisoners noted a statistically significant mean increase in systolic blood pressure (SBP) when they were moved from single-occupancy cells to multiple-occupancy dormitories (D’Atri, et al., Crowding in Prison: The Relationship Between Changes in Housing Mode and Blood Pressure (1981) 43 (2) Psychosomatic Medicine, pp. 95-105). For those who remained in a single cell, the study noted little mean change in SBP. Rises in SBP are associated with stress and can lead to other health complications like heart disease.
(3) Sleep deprivation is linked to decreased mood and can undermine emotional capacity or the ability to experience positive emotions like joy, happiness, and contentment. In addition to blunting these emotions, sleep deprivation increases anxiety (Palmer, et al., Sleep Loss and Emotion: A Systematic Review and Meta-analysis of Over 50 Years of Experimental Research (2024) 150 (4) Psychological Bulletin, pp. 440-463). When individuals are in a state of anxiety, they function from a heightened amygdala, which places a person in a state of “fight or flight.”
(4) Moreover, sleep deprivation degrades normal reciprocal associations, which means that it impairs a person’s ability to read simple and complex social cues that can result in misreading of perceived threats. Individuals who have restful sleep (i.e., those able to engage in REM sleep) were able to have a next-day improvement in emotional discrimination. This highlights the psychological and physiological importance of restorative sleep (Goldstein-Piekarski, et al., Sleep Deprivation Impairs the Human Central and Peripheral Nervous System Discrimination of Social Threat (2015) 35 (28) The Journal of Neuroscience, pp. 10135-10145).
(5) While there are studies that show a correlation between an increased risk of suicide and single-occupancy cells, that correlation may be linked to who was placed in single cells (i.e., violent persons or persons with severe mental health issues) and the purpose for this solitary placement (Fazel, et al., Suicide in Prisons: An International Study of Prevalence and Contributory Factors (2017) 4 (12) 4 Lancet Psychiatry, pp. 946-952). This act recommends that single-occupancy cells be used as a reward and preference to promote healing, not to inflict punishment.
(c) Violence among those in prison in shared housing is an ongoing issue that jeopardizes the safety of both incarcerated persons and correctional staff. As has been reported, an overflow of people in prisons increases stress between those confined and correctional officers. This has historically led to increased violence and poor conduct between correctional officers and people who are incarcerated. Reductions in overcrowding and turnover appear critical in reducing vulnerability for people who are incarcerated (Baggio, et al., Do Overcrowding and Turnover Cause Violence in Prison? (2020) 10 Front. Psychiatry 1015, https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2019.01015/full).
(d) To best position incarcerated persons to engage in rehabilitative programming and to promote public safety by reducing recidivism, while simultaneously ensuring better safety and security for correctional staff, it is the intent of the Legislature that the Secretary of the Department of Corrections and Rehabilitation implement a plan to begin housing more incarcerated persons in single-occupancy cells.

(11) The inclusion or exclusion criteria, or both, the secretary, or their designee, used to designate incarcerated persons to single-occupancy cells, by facility.
(12) A qualitative description of the changes made in each of the four pilot sites in order to implement this pilot program.

(1) Persons housed in safety cells.
(2) Persons housed in detoxification cells.
(3) Persons housed in temporary holding cells or rooms.
(e) Participation by an incarcerated person in the single-occupancy cell pilot program shall be voluntary, and an incarcerated person may request to be transferred from a single-occupancy cell to a non-single-occupancy cell at any time.
(e)
(f) If an incarcerated person requests to be housed in a pilot site and the secretary, or their designee, denies the inmate’s request for that housing, that denial shall not constitute a cognizable cause of action.
(g) The creation of the single-occupancy cell pilot program shall not result in any new construction of state prison facilities.
(f)
(h) A report to be submitted pursuant to subdivision (c) shall be submitted in compliance with Section 9795 of the Government Code.
