Overton County (county seat: Livingston) covers 433 (land) square miles with a population of 22,511 (2020). Official county website: overtoncounty.org/. This page summarizes the verified building-regulation posture of unincorporated Overton County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
OPT OUT on the official SFMO roster (accurate as of 10/24/2025): no state residential building permit/inspection for 1-/2-family dwellings on unincorporated land. 8 (not 10) — state electrical permits + TDEC septic apply and opt-out can lapse. NOTE the seat, Livingston, is EXEMPT (enforces its own residential code) — stricter carve-out inside the city.

The full card details which of these bite in Overton County and how hard.
The score describes unincorporated county land only. Inside Overton County, incorporated municipalities set their own, usually stricter, rules — including: Livingston. Land inside town limits follows town code.
