Do I need a permit for shed or accessory structure in Unincorporated Lake County?
Unincorporated Lake County does not issue residential building permits. Lake County passed a resolution opting out of the state residential building program, so no county or state residential building permit is required in the unincorporated county. An owner may voluntarily request a state building permit and SFMO inspection (Tenn. Code Ann. 68-120-101(b)(1)(D)) to obtain a certificate of occupancy. Zoning, septic and electrical rules may still apply.
The requirements below come from Tennessee rules and describe the standard the work must still meet. They are not a statement that Unincorporated Lake County will issue you a permit.
It depends. Whether shed or accessory structure needs a permit in Unincorporated Lake County comes down to the details of your project.
Tennessee does not set one statewide shed threshold, and the 200 square foot figure from the model International Residential Code does not govern here. Who enforces residential construction depends on your address: where a city or county has neither taken on residential code enforcement itself nor opted out by a two-thirds vote of its legislative body, the State Fire Marshal's Office runs the residential permit and inspection program using state-contracted inspectors. So the first question is not the size of the shed but which authority covers you. Confirm whether your city or county enforces its own code, has opted out, or falls under the State Fire Marshal program, then ask that office for the size threshold. Zoning setbacks apply regardless, and a separate permit is needed for any electrical service run to the shed.
