Buying Land in Adams County, Iowa

Zoning and the 2025 Comprehensive Plan

Adams County has adopted Chapter 335 zoning (unlike some of its southwest Iowa neighbors, which have not -- see our Adair County page) and administers it through its own Chapter 21 Zoning Ordinance and a Zoning Commission appointed by the board of supervisors. The county adopted a new Comprehensive Plan in September 2025, covering both unincorporated Adams County and the City of Corning, replacing whatever plan predated it. Because the zoning ordinance is meant to implement the comprehensive plan, confirm you're working from the post-2025 version of both documents -- older cached copies won't reflect the renewable-energy chapter described below.

Wind and solar: rewritten in 2024-2025, with real numbers attached

Adams County spent 2024 into 2025 rewriting its wind and solar rules from scratch, with a countywide turbine cap, specific setback and noise/flicker limits, a solar moratorium that ran through May 1, 2025, and a proposed 400-acre countywide solar ceiling -- all folded into a new Renewable Energy Chapter added to the county's Comprehensive Plan. See our dedicated wind and solar leasing page for the exact caps, setbacks, and current ordinance status before assuming either is available on a specific parcel.

Septic and wells are handled in-house

Unlike Adair or Audubon Counties, which contract this function out, Adams County staffs its own Environmental Health program directly, handling private septic and private well permitting for county property along with free well water testing. This is a normal, standard-issue Iowa environmental health office -- the distinctive fact here is what it is not (contracted out), which typically means faster local turnaround and a single office to call for both septic and well questions.

Farmland values, the local ag economy, and Lake Icaria recreation

Adams County's farmland is priced well below the state average: the 2025 Iowa State University Land Value Survey put the county's average value at $8,113 per acre, essentially flat versus 2024 and roughly 30% below Iowa's statewide average of $11,549 per acre -- among the more affordable counties in the state for buying farmland outright. Agriculture anchors the local economy: the county's roughly 509 farms span about 223,454 acres, and livestock is a major share of that -- 41,682 cattle and calves and 49,787 hogs and pigs counted in the county's most recently reported inventory -- alongside row-crop corn and soybean production, consistent with Adams County's standing as Iowa's least-populous county with a still fully working rural economy.

The county's other notable land-use asset sits apart from row crops and pasture: Lake Icaria, a 650-acre lake completed in 1978 and managed as a county recreation area by Adams County Conservation. It includes two campgrounds (153 total sites, mostly graveled, split between full-service, water/electric, and tent sites), six full-service cabins, eight sleeper cabins, and two lakeside cottages, all open for public reservation. Land bordering or near the lake carries a real recreational-proximity value distinct from the county's ag land generally -- worth factoring in separately if a specific parcel sits near the Lake Icaria recreation area.
