Wayne County (county seat: Waynesboro) covers 734 square miles with a population of 16,232 (2020). Official county website: waynecountytn.org/. This page summarizes the verified building-regulation posture of unincorporated Wayne County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
OPT OUT on the official SFMO roster (as of 10/24/2025): the county has passed a resolution opting out of the State Residential Building Program, so 1-/2-family dwellings on unincorporated land face no state residential building permit or inspection (owner may voluntarily request an SFMO Certificate-of-Occupancy inspection). Sits at 8 rather than 10 because state electrical permits + TDEC septic still apply and the opt-out can lapse (180-day renewal). Incorporated towns are stricter — see exceptions.
The claim above is source-verified (official statute/county documents; URL, direct quote, and date on the full card). Method: how we verify.
No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Wayne County and how hard.
The score describes unincorporated county land only. Inside Wayne County, incorporated municipalities set their own, usually stricter, rules — including: Waynesboro, Clifton, Collinwood. Land inside town limits follows town code.
Building rules are the first question people ask about Wayne County — and the easiest one to answer. They're rarely the one that decides it. The full card grades all ten dimensions, every claim quoted from the county's own code.
