Senate Bill 7 amends Tennessee Code Annotated to enhance protections for historic properties by restricting the actions of the Tennessee historical commission and other state entities involved in historic preservation. Specifically, the bill prohibits these entities from approving or recommending any renovations, alterations, or demolitions of structural design elements of real property deemed to have historical, architectural, or cultural significance. Additionally, it prevents them from taking adverse actions against property owners, such as imposing civil penalties or fines.

However, the bill allows the Tennessee historical commission to approve or recommend alterations or renovations only to the aesthetics and non-structural elements of historic properties that are listed on the Tennessee register of historic places. This legislative change aims to safeguard the integrity of historically significant properties while still permitting some level of modification under specific conditions. The act is set to take effect upon becoming law.
