HB 2997 mandates that all Texas Department of Criminal Justice (TDCJ) facilities maintain indoor temperatures between 65°F and 85°F in areas where inmates are housed or staff regularly work. The bill requires the installation of electronic temperature gauges in multiple facility locations, including dormitories, medical areas, kitchens, restrooms, and administrative offices. It also requires TDCJ to publish a quarterly temperature log online and submit an annual report detailing air conditioning failures, non-compliance incidents, and corrective actions. TDCJ must fully comply with temperature standards by September 1, 2026, with progress reports due by that date. The first required compliance report must be submitted by December 1, 2027
