Madison County (county seat: Huntsville) covers 834 square miles with a population of 16,521 (2020). Official county website: madisoncountyar.gov/. This page summarizes the verified building-regulation posture of unincorporated Madison County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No county building department and no county building code on unincorporated land: Madison follows the standard rural-Ozark Arkansas pattern (state residential code nominally 'applies' but there is no local building official/AHJ to enforce a permit or inspection of an owner's home). Unlike batch-7's Marion County AR, no county-wide development/occupancy permit + inspector was found. Owner-builders proceed without a county building permit in practice; scored 9 (just below a formal 'no-code' anchor). County offices are clerk/assessor/collector/sheriff-type — no building/inspection department.
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 Madison County and how hard.
The score describes unincorporated county land only. Inside Madison County, incorporated municipalities set their own, usually stricter, rules — including: Huntsville, St. Paul / Hindsville / Kingston. Land inside town limits follows town code.
Building rules are the first question people ask about Madison 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.
