Gibson County (county seat: Princeton) covers 499 square miles with a population of 33011. Official county website: gibsoncounty-in.gov/ordinances/. This page summarizes the verified building-regulation posture of unincorporated Gibson County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
The county has no planning/building department and repealed zoning in 2021; state Class 2 residential code standards still legally apply, but there is no county permit-and-inspection gate for a new house on unincorporated land — septic and floodplain permits are the practical requirements.
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 Gibson County and how hard.
The score describes unincorporated county land only. Inside Gibson County, incorporated municipalities set their own, usually stricter, rules — including: Princeton, Fort Branch, Haubstadt, Oakland City, Owensville, Francisco, Hazleton, Mackey, Patoka and Somerville have their own zoning/building permit regimes — Princeton requires a city building permit and charges $100 plus $0.05/sq ft.. Land inside town limits follows town code.
Building rules are the first question people ask about Gibson 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.
