Public facilities; prohibit from being constructed with flat or low-slope roofs.

HB 1730 prohibits the use of flat or gently sloping roofs (less than 3:12 slope) in new construction of publicly funded buildings in Mississippi, such as state offices, schools, and government facilities. It requires all new covered public facilities built with government funds to have primary roofs with a minimum slope of 3 inches rise per 12 inches horizontal. Limited exceptions apply for mechanical equipment areas, small accessory structures, or documented engineering constraints affecting no more than 10% of the roof area. Project entities must certify compliance before receiving funding, permits, or construction approval, with potential fund recovery for noncompliance. This applies to all new construction, not renovations or repairs.
