Relating to: climate control in state correctional institutions and county jails and houses of correction and making an appropriation. (FE)

AB 734 establishes specific temperature standards for state correctional institutions and county jails, requiring indoor temperatures to stay between 68°F and 76°F at all times in housing units. It mandates facilities to record temperatures in common areas and random cells during extreme weather (below 10°F or above 90°F) and submit annual reports to the legislature. The bill appropriates $65 million for 2026-27 to install and operate heating, ventilation, and air conditioning systems, with phased implementation: one-third of facilities by 2029, another third by 2031, and the final third by 2035. This directly affects all state prisons and county jails/houses of correction in Wisconsin, requiring them to meet new climate control requirements and report compliance data.
