Jails and prisons segregated housing limited, solitary confinement prohibited, rulemaking authorized, and reports required.

HF 1628 prohibits solitary confinement in Minnesota jails and prisons, defined as cell confinement depriving inmates of meaningful visual or auditory contact for more than 20 hours in a day or 45 hours in any three-day period. It directly affects all inmates in state and local adult correctional facilities, with special protections for vulnerable populations like minors, pregnant individuals, people with mental illness, or those with serious medical conditions. The bill requires facilities to document segregation placements, submit quarterly reports to the Corrections Commissioner, and adopt rules identifying vulnerable individuals. It also bans "unassigned idle" confinement exceeding 10 hours daily and mandates that segregated housing conditions approximate those in general population.
