Clinton County (county seat: Frankfort) covers 405 square miles with a population of 33190. Official county website: www.clintonco.com/apc/.

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 Clinton County and how hard.
The score describes unincorporated county land only. Inside Clinton County, incorporated municipalities set their own, usually stricter, rules — including: City of Frankfort — has its own planning jurisdiction outside the county APC, Towns of Mulberry, Rossville, Kirklin, and Colfax are served by the county Area Plan Commission and are subject to the same UDO. Land inside town limits follows town code.
Building rules are the first question people ask about Clinton 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.
