Hardin County (county seat: Savannah) covers 577 square miles with a population of 26831. Official county website: www.hardincogov.com/. This page summarizes the verified building-regulation posture of unincorporated Hardin County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
State DBI list shows Hardin County as OPT OUT — the county has exempted itself from statewide standards for one- and two-family dwellings, so there is no mandatory residential building code enforcement on unincorporated land. A state permit and inspection are available voluntarily (an inspector is listed for the county) if an owner wants a Certificate of Occupancy for lending purposes.
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 Hardin County and how hard.
The score describes unincorporated county land only. Inside Hardin County, incorporated municipalities set their own, usually stricter, rules — including: Savannah (DBI status EXEMPT — city zoning and city codes enforced), Adamsville (EXEMPT), Crump (OPT OUT), Saltillo (SRBP). Land inside town limits follows town code.
Building rules are the first question people ask about Hardin 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.
