Tennessee Code Title 13. Public Planning and Housing § 13-7-212

(a) Any municipality that has exercised zoning powers under this part shall compile its zoning ordinance and map, as amended, that is in effect so as to be able to provide any member of the public with a current zoning ordinance and map. In that municipality, the municipal legislative body shall authenticate, compile, update, keep, maintain and make available the zoning ordinance, map and all amendments as a public record. Any municipal zoning ordinance and map made available to the public through a compilation made pursuant to this section, whether in electronic or paper form, shall be presumed to be a true and accurate statement of the municipality's zoning ordinance and map.

(b) Any party challenging the accuracy of any municipal zoning ordinance or map compiled or codified as currently in effect in accordance with this section, whether in a rezoning proceeding before a municipal governing body, an appeal to a board of zoning appeals, a subdivision or site plan approval proceeding before a planning commission or in any judicial proceeding, must prove the inaccuracy of the zoning ordinance or map by clear and convincing evidence.
