Tennessee Code Title 13. Public Planning and Housing § 13-7-406

Prior to the establishment of any historic district or zone, the historic zoning commission or the regional historic zoning commission also shall adopt for each such proposed district or zone a set of review guidelines, which it will apply in ruling upon the granting or denial of a certificate of appropriateness as provided for in this part. Such review guidelines shall be consistent with the purposes of this part and with regulations and standards adopted by the secretary of the interior pursuant to the National Historic Preservation Act of 1966 (16 U.S.C. § 470 et seq.), applicable to the construction, alteration, rehabilitation, relocation or demolition of any building, structure or other improvement situated within a historic district which has been certified by the secretary of the interior as a registered historic district. Reasonable public notice and opportunity for public comment, by public hearing or otherwise, shall be required before the historic zoning commission or the regional historic zoning commission adopts any such review guidelines.
