Buying Land in Decatur County, Indiana
Seat Greensburg, in east-central Indiana. Decatur County's zoning runs through a County Area Plan Commission, but the county's most consequential land-use fact is Honda's roughly 1,700-acre auto assembly plant near Greensburg -- a single employer whose workforce demand has already produced the area's first new residential subdivision in fifteen years.
Zoning: a County Area Plan Commission, with Greensburg zoning separately
Decatur County has adopted countywide zoning, administered by the Decatur County Area Plan Commission (150 Courthouse Square, 1st Floor Suite 106, Greensburg), which processes rezoning petitions, ordinance amendments, and related land-use requests for unincorporated territory under the county's zoning ordinance -- including distinct Agriculture and Industrial District articles. The City of Greensburg maintains its own separate Plan Commission and zoning ordinance for land within city limits, so confirm which body has jurisdiction before assuming county zoning applies to a specific parcel near town.
Given the industrial development described below, a buyer evaluating land anywhere near the Honda plant, its supplier park, or the U.S. 421/I-74 corridor should specifically confirm current zoning district and any industrial-buffer or overlay provisions with the Area Plan Commission directly, since land-use classification near a major employer can be more actively managed than in a purely agricultural part of the county.
Honda: the single fact that shapes Decatur County land economics
In 2006, Honda selected a roughly 1,700-acre tract near Greensburg for a new $550 million North American assembly plant, and reportedly acquired the needed land at about 75% above its assessed value, plus a $6,000 signing bonus per landowner who agreed to sell -- an unusually generous, well-documented land-acquisition premium for a rural Indiana county. The plant began producing Civic sedans on October 9, 2008, and has since grown into a facility producing roughly 250,000 Civic and CR-V vehicles annually with about 2,400 employees, drawing workers from more than 30 counties across Indiana, Ohio, and Kentucky. Honda is Decatur County's largest taxpayer.
That single employer has a documented, concrete effect on the local housing and land market: reporting describes a 102-home market-rate subdivision built to meet Honda-and-supplier workforce demand as the area's first new residential subdivision in 15 years, alongside a planned 80-unit apartment complex in downtown Greensburg. Local real estate coverage describes Decatur County as remaining relatively affordable within the broader Indianapolis region even with this steady workforce-driven demand -- homes commonly range from the $150s for established single-family properties in Greensburg and the rural towns up to the $300s for larger or acreage properties. See our dedicated subdivision-development page for Decatur County for what this pattern means if you're evaluating new residential development or comparing land near versus away from the Honda corridor.
Septic and other departments to know
Septic permitting in Decatur County runs through the county Health Department's Environmental Health division, which requires a soil test completed by a soil scientist before a septic permit will be issued. Where a system needs an off-lot easement, the county requires that easement be legally recorded at the courthouse, with a copy submitted to the Health Department, before the permit is issued -- a specific, verifiable procedural step worth planning for if a parcel's suitable drain-field area doesn't sit entirely within its own boundary lines. A registered installer must also contact the county inspector before beginning work.
The Decatur County Assessor's office ((812) 663-4868) and county GIS mapping resources, and the County Recorder ((812) 663-4681), all based at the courthouse in Greensburg, cover parcel valuation, GIS data, and recorded deeds, easements, and plats respectively. Given Honda's presence and the resulting workforce-housing demand described above, expect land near Greensburg and the U.S. 421 corridor to see more active development interest than more purely agricultural parts of the county.
