Tennessee Code Title 7. Consolidated Governments and Local Governmental Functions and Entities § 7-84-304

In any case where a notice is required to be sent to the owner of real property in the central business improvement district, such notice shall be deemed sufficient if sent by certified mail to the last known address of the owner. In any case where the governing body finds for any reason that due notice was not given, the governing body shall not lose jurisdiction by due notice not being given, and the proceeding in question shall not be void or be abated by due notice not being given, but the governing body, in that case, shall order due notice given and shall continue the proceeding until such time as notice shall be properly given, and thereupon shall proceed as though notice had been properly given in the first instance.
