Buying Land in Hancock County, Iowa

Zoning: a real township-by-township patchwork, not a single countywide rule

Unlike a county with one zoning ordinance covering its entire unincorporated area, Hancock County's zoning is genuinely partial: of its 17 townships, only 10 have adopted a zoning ordinance, leaving the remaining townships without a county-level zoning framework at all. Where zoning is in effect, it's administered by the county Zoning Office out of the courthouse in Garner, with a 7-member Zoning Commission responsible for the ordinance's language and content -- and for approving subdivision plats before the Board of Supervisors can legally record them -- and a 5-member Board of Adjustment that functions as the more judicial arm of the process, hearing variance requests and translating the ordinance's language into actual approved or denied uses.

This structure means a use, setback, or building requirement that applies on one side of a township line may simply not exist on the other. Before treating any zoning rule as a given for a specific Hancock County parcel, confirm directly with the Zoning Office (Zoning Administrator Andy Buffington, (641) 923-2702) both which township the parcel sits in and whether that township is one of the 10 with an adopted ordinance.

Subdivisions and floodplain permits both route through the same Zoning Office

Hancock County adopted its subdivision ordinance on January 13, 2003. Under it, the Zoning Commission must review and approve a proposed subdivision plat before the Board of Supervisors can give it final approval and it can be recorded -- a two-step process that applies on top of whatever township-level zoning rules govern the parcel being divided.

Floodplain development is governed by the county's Flood Plain Management Ordinance, last amended October 31, 2022, which adopts the county's FEMA Flood Insurance Study and accompanying maps by reference and requires a floodplain development permit -- issued through the same Zoning Office -- before any structure is built, extended, or substantially altered within a mapped flood hazard area. Notably, the headwaters of the Iowa River itself are in Hancock County, where its East Branch and West Branch originate before joining in neighboring Wright County; confirm a specific parcel's flood-zone status directly with the Zoning Office rather than assuming upstream location means no flood exposure.

Wells and septic: standard fees, one Environmental Health office

Hancock County Environmental Health, based at 855 State St. in Garner, issues both private well and septic permits for the unincorporated county. A new well permit runs $175 and a well reconstruction permit runs $250; the department also handles well water testing. Septic system installation requires a site and soil analysis by the department before work can begin, and while this research confirmed the well permit fees directly from the department's own pages, it could not confirm the current septic permit fee -- verify that amount directly with the department before budgeting for a new system. As in every Iowa county, a septic system serving a property here must be inspected by a DNR-certified inspector before a covered sale closes, under the state's 2009 Time of Transfer law.

Farmland values: solidly mid-pack, with real spread by soil quality

Hancock County's 2025 average farmland value came in around $11,527 per acre, down about 2.5% from the prior year -- a respectable but not top-tier figure among Iowa's strongest row-crop counties. Individual sales vary well outside that county average: recent reporting on lower-CSR2 or mixed-use tracts in Hancock and similar counties put per-acre prices as low as $4,400 to $5,700, underscoring that a county average is a starting point, not a substitute for a parcel-specific CSR2 lookup and recent comparable sales in the specific township where a tract sits.

Hog confinements: the same debate has recurred for more than a decade

Hancock County has processed hog-confinement construction permit applications repeatedly since at least 2010, and the pattern is well documented by name, township, and outcome. In 2010, supervisors unanimously recommended denying a Prestage Farms LLC application for a 4,800-head confinement in Amsterdam Township, but Board Chair Sis Greiman noted at the time that because the project met the state's Master Matrix scoring requirements, the county's own vote wouldn't actually stop construction. In 2019, supervisors unanimously recommended approval of a Summit Farms Pork LLC application for two deep-pit swine barns (just under 5,000 head) in Ell Township, over a resident's objections about odor, dust, and truck traffic; Greiman again characterized the county's role as largely limited to forwarding construction details to Iowa DNR. In 2022, the county approved a similar two-building, roughly 5,000-head-per-building application near Forest City. A separate Summit Farms LLC application in Erin Township drew a 40-minute public hearing where nearly 20 residents raised health, odor, and water-quality concerns, and passed on a 2-1 vote with Greiman dissenting.

Taken together, this is a real, recurring pattern spanning more than a decade rather than an isolated dispute -- and it consistently comes down to the same dynamic: a matrix-qualifying application will typically be permitted by the state regardless of local objection or even a county supervisor's own vote.
