Zoning in Butler County, Kansas

Butler County runs one of the more developed county zoning frameworks in rural Kansas, built around a Comprehensive Development Plan and a set of numbered agricultural and residential districts for unincorporated land. Knowing which district covers a specific parcel -- and what its minimum acreage actually is -- matters before assuming a tract can be split, built on, or used the way a listing implies.

This page covers what's specific to Butler County. For the general explanation, see the national guide.

The county's base districts, and what their acreage minimums actually mean

Butler County's zoning and subdivision regulations, most recently amended in 2011 and administered by the Community Development-Planning & Zoning division in El Dorado, organize unincorporated land into a set of numbered agricultural and residential districts. AG-80, the county's principal large-lot agricultural district, carries an 80-acre minimum for a buildable lot; a less restrictive AG-40 district sets that minimum at 40 acres; and RR (Rural Residential), the district most relevant to a smaller acreage or homesite purchase, sets a 3-acre minimum. A parcel's actual district assignment -- and therefore whether it can legally be split further, or whether a smaller existing tract is a lawful nonconforming lot -- has to be confirmed against the county's own zoning map rather than assumed from a listing's acreage alone.

Uses that don't fit squarely within a district's permitted-use list aren't necessarily prohibited outright: Butler County's code allows Conditional Uses, for uses that could have an adverse effect on nearby properties or the district's character, to proceed with additional requirements attached after Planning Commission review -- a real, more flexible middle path between an outright permitted use and a denial. A buyer planning something other than straightforward single-family residential or agricultural use (a small commercial operation, an event venue, a larger outbuilding complex) should ask the Planning & Zoning division directly whether a conditional-use process applies to a specific parcel and use before assuming either outright permission or an outright bar.

Building permits, agricultural exemptions, and where to start

Butler County's building, electrical, mechanical, and plumbing permit fees run under Resolution 99-02, based on the 1997 Uniform Building Code, with fee amounts set by a schedule the Board of County Commissioners adopts separately from the code itself. One exemption worth knowing before budgeting for a build: nonresidential structures used solely for agricultural purposes are exempt from paying those permit fees under the county's own fee schedule -- a real, practical savings for a buyer planning a barn, machine shed, or similar farm structure rather than a residence.

For any specific unincorporated Butler County parcel, start with the county's own Community Development-Planning & Zoning division to confirm the parcel's current zoning district, its permitted and conditional uses, and applicable setbacks, and use the county's Apply for Permits page and GIS-based permitting portal to begin a building or zoning permit application. A parcel inside El Dorado or another incorporated city instead falls under that city's own separate zoning and building code, so confirm jurisdiction first if a parcel sits near a city boundary.
