Regulatory framework
The code baseline for Chase County.
Chase County's official commissioners page states that the county has no zoning requirements or building permits outside city limits. County-level floodplain development follows the Floodplain Management Ordinance and Kansas requirements in K.S.A. 12-766 and K.A.R. 5-44-1 through 5-44-7; no countywide 2026 technical building-code edition was identified.
Inspection lane
For floodplain work, contact the Kansas Department of Water Resources before applying, then submit the completed Floodplain Development Permit Application to the County Floodplain Manager; the application requires project, flood-map, elevation, and other-agency permit information and allows inspection. For private wastewater, submit the county wastewater application and coordinate inspection with the Sanitarian at 620-794-5053. Contact the relevant city for ordinary building inspections inside city limits.
