Roane County - Subject to local approval, repeals act that designated the chief executive officer of the county as the county executive. - Amends Chapter 1 of the Private Acts of 2007.

SB 2176 repeals a 2007 local law that designated Roane County's top official as "County Executive" instead of the standard "County Mayor" used in most Tennessee counties. The bill aligns Roane County's title with Tennessee's general law (TCA § 5-6-101), reducing confusion during inter-county projects. It requires Roane County's legislative body to approve the change by a two-thirds vote before taking effect. This directly affects Roane County's leadership title and administrative processes, but does not alter the official's duties or powers.
