Who issues building permits in Lyon County?
Planning and Zoning administers the county zoning, subdivision and floodplain rules for unincorporated Lyon County, from the same courthouse office as Floodplain Management; Samuel Seeley is the Director. The county building permit is a review against the zoning regulations adopted by Resolution 02-21, which set parcel types, building placement and building form.

What the county reviews
Under Section 8 of the zoning regulations, building, rebuilding, extending, repairing, renovating or altering any building, structure or site, and any change of use, is reviewed by the Zoning Administrator. No review is needed for:
- Interior or exterior alterations that do not change the footprint, height or massing of a structure
- Routine maintenance and minor repairs that do not need a building permit
The county’s permit list includes building permits, permitted use permits, non-agricultural home occupations, short-term rentals, temporary uses, quarries, commercial wind (WECS) renewals and signs. Parcels of 40 acres or more are treated as agricultural without an exemption request, but you still have to check whether the development is in a floodplain; smaller agricultural parcels can apply for an Agricultural Exemption Determination.
Lyon County permit fees
Fees come from Resolution 13-21, the zoning, subdivision and floodplain schedule adopted on April 1, 2021. All fees double when the permit is applied for after the fact, and none are refunded.

What the application needs
Section 8 asks for whichever of these items apply to the project:
- A map showing the site on the Lyon County Regulating Plan, with its parcel type
- A table comparing the project with the building, landscape and supplemental standards for that parcel type
- Scaled project plans showing owners, property lines, rights-of-way and easements, natural features, floodplains, grading and drainage, and the distance from each property line to every new building
- Existing and proposed utilities and a landscaping plan
- Photographs of the site and the neighboring properties
- Elevations and wall sections of new or changed buildings, and a sign plan
The lot must also meet the county sanitation code for sewage treatment. For a site outside the city limits, Emporia’s plan checklist lists the Lyon County Health Department as the approval for the sewage system.

A house in a floodway also needs a permit from the Kansas Department of Agriculture Division of Water Resources and possibly the U.S. Army Corps of Engineers, and the county checks those permits before issuing its own.
Right-of-way: construction or landscaping in a public right-of-way needs a permit from the City of Emporia or the Lyon County Engineer’s Office.
Americus fees: the City of Americus raised its building permit fees under Ordinance 633, published on April 17, 2026: $50 up to $1,000 of valuation, $100 to $25,000, $150 to $50,000, $200 to $75,000, $250 to $100,000 and $350 above that.
