HB 73 prohibits the Tennessee Historical Commission and other state entities (except the state building commission) from regulating or taking adverse actions against owners regarding renovations, alterations, or demolition of real property that is **not listed** on the Tennessee Register of Historic Places. The bill specifically applies to properties with historical, architectural, or cultural significance that do not meet the registration criteria. It allows the commission to continue regulating listed properties (those on the Tennessee Register) for aesthetic, non-structural changes. This bill amends Tennessee Code Titles 4, 7, 8, 13, and 66 to clarify regulatory boundaries for historic preservation.
