Polk County (county seat: Mena) covers 862 total (858 land) square miles with a population of 19,221 (2020 Census). Official county website: portal.arkansas.gov/counties/polk/. This page summarizes the verified building-regulation posture of unincorporated Polk County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No Polk County building department exists; the Arkansas building-resources directory lists the county's only permit resource as the City of Mena building inspector page, i.e. there is no county-level permit or inspection for unincorporated land. The statewide Arkansas Fire Prevention Code (2021 IRC-based) applies 'even in rural and unincorporated areas' but is largely unenforced there ('inspections may be infrequent or available only upon request'). De facto code-free rural building = ~9; not 10 because a state code nominally exists on the books.
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 Polk County and how hard.
The score describes unincorporated county land only. Inside Polk County, incorporated municipalities set their own, usually stricter, rules — including: Mena, Cove, Grannis, Hatfield, Vandervoort, Wickes. Land inside town limits follows town code.
Building rules are the first question people ask about Polk 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.
