Buying Land in Gibson County, Indiana

Seat Princeton, in far southwestern Indiana. Gibson County briefly had county-wide zoning in 2020, then repealed it in 2021 after a commissioners' election specifically fought over the issue -- so it's genuinely unzoned today outside its incorporated towns. It's also home to Duke Energy's Gibson Generating Station, a 2,845-megawatt coal plant that's one of the largest in the country.

No County-Wide Zoning -- Repealed After Only Months in Effect

Case-by-case / verify locally

Gibson County adopted zoning in August 2020, then repealed it in a 2-1 commissioners' vote in early 2021. Unincorporated Gibson County has no zoning ordinance or use-district map today, though its incorporated towns kept their own separate zoning. See our dedicated zoning page for the full story.

A County-Wide Licensing Requirement Exists for Solar and Wind

Case-by-case / verify locally

In place of zoning, the county adopted a narrower licensing requirement that specifically covers solar panel and wind turbine installations -- confirm current terms before pursuing an energy lease or installation.

Septic Runs Through the County Health Department

Generally favorable

The Gibson County Health Department issues septic permits under statewide ISDH rules, requiring a soil profile analysis from a certified soil scientist.

Zoning: adopted in 2020, repealed in 2021 -- Gibson County is genuinely unzoned

Gibson County is one of the roughly dozen of Indiana's 92 counties without a county-wide zoning ordinance today -- but it got there in an unusual way. The county was, for years, the only Indiana county with no zoning at all, until its commissioners unanimously approved a new comprehensive zoning ordinance in August 2020 following work by a citizen Area Plan Commission that had been formally appointed back in November 2017. That ordinance did not last: in the following county-commissioners election, two candidates campaigned specifically on a promise to repeal it, won their races, and voted 2-1 in early 2021 to do exactly that -- one of the more direct, ballot-box-driven zoning reversals documented in any Indiana county on this site.

The practical result today: unincorporated Gibson County has no comprehensive zoning ordinance, no use-district map, and no zoning-based variance process -- a genuinely different regulatory environment than a zoned Indiana county, where building a home, a pole barn, or converting agricultural land to a different use generally does not require zoning approval, though state building code, floodplain rules, and the county's health-department septic requirements described below still apply regardless. Gibson County's incorporated towns that had their own separate municipal zoning before the county's brief 2020-2021 experiment kept it independently, so confirm directly whether a specific parcel sits inside or outside a town's separate zoning jurisdiction. In place of comprehensive zoning, the county adopted a narrower county-wide licensing requirement that applies specifically to solar-panel and wind-turbine installations -- see our dedicated zoning topic page for Gibson County for the fuller history and what that licensing requirement covers.

Home to Duke Energy's Gibson Generating Station

Gibson County hosts the Gibson Generating Station, a five-unit, 2,845-megawatt coal-fired power plant in Montgomery Township that's Duke Energy's largest facility and the second-largest coal plant in the United States by capacity -- built between 1976 and 1982 and jointly owned and operated by Duke Energy Indiana, Wabash Valley Power Association, and the Indiana Municipal Power Agency. The plant sits on a large site that also includes a 160-acre wetland wildlife habitat and recreation area, and as of recent reporting Duke Energy has proposed a three-year life extension (to 2038) with a retrofit allowing the plant to run on natural gas as well as coal, rather than the previously planned 2035 retirement.

For a land buyer, a facility of this scale has real practical implications beyond the immediate plant site: expect a meaningful concentration of transmission infrastructure, coal-ash management areas, and industrial rail/barge access in the surrounding township, along with an economic base more tied to a single large employer than a typical rural Indiana county. If you're evaluating land near the plant specifically, ask directly about any recorded utility easement, transmission-line right-of-way, or ash-basin buffer area that could affect the parcel, since these details don't necessarily show up on a standard plat.

Septic permitting and other departments to know

Because Gibson County has no zoning ordinance, the county Health Department's septic-permitting process is, in practice, the single most consequential piece of county-level land-use regulation a typical rural land buyer will encounter here. The Gibson County Health Department, based at 203 S. Prince Street in Princeton, issues septic permits under Indiana's statewide 410 IAC 6-8.3 rule; the process requires a soil profile analysis performed by a certified soil scientist before the health department will specify the required system size and type and issue a permit.

The Gibson County Assessor's office and Auditor's office, both based in Princeton, handle property valuation and parcel records, and the County Recorder holds deeds, easements, and plats. Given the county's unzoned status, a title search and a direct conversation with the Recorder's office about any recorded easement (including utility easements tied to the Gibson Generating Station) matter more here than in a zoned county, where a zoning map alone would flag some of that context.

What we could and couldn't confirm

Gibson County's zoning adoption (August 2020) and repeal (early 2021, 2-1 commissioners' vote following an election fought specifically over the issue) are confirmed via multiple WEHT/WTVW (Eyewitness News) reports and Princeton Daily Clarion opinion coverage from the period, giving this an unusually well-documented before-and-after record for an Indiana zoning reversal. The county-wide solar/wind licensing requirement adopted in place of comprehensive zoning is drawn from the same news coverage; this research pass could not confirm that licensing ordinance's exact current text or fee structure. The Gibson Generating Station's specifications (2,845 MW, five units built 1976-1982, joint ownership) are confirmed via Duke Energy's own site and cross-checked against Wikipedia/Global Energy Monitor entries; this page specifically excludes the AB Brown (Posey County) and F.B. Culley (Warrick County) plants that an initial broad search on the regional utility incorrectly suggested might be located in Gibson County. Direct WebFetch access to gibsoncounty-in.gov was not attempted in this pass, so current department contact details and the licensing ordinance's precise terms should be confirmed directly.

Who to Call Before Buying Land in Gibson County

Direct WebFetch access to gibsoncounty-in.gov was not attempted in this research pass, so several department details reflect search-indexed content rather than a full verbatim site read -- confirm current staff, hours, and the exact scope of the county's solar/wind licensing requirement directly before relying on this page for a specific parcel.
