Accessory Dwelling Unit (ADU) Requirements in Sevierville, TN?

[Brett Shoemaker]

Hi all, Looks for some high level info related to Accessory Dwelling Unit possibilities and requirements for those in the Sevier County, Sevierville, TN and Smoky Mountains area. If anyone has a shortened bullet points of what's allowed/permissible with a reference guide of requirements, I'd appreciate any guidance. I've reviewed online, but my search shows discrepancies & mismatch information. Many apologies if this isn't the correct forum.
