Project questions
Frequently asked questions for Lyon County
Who handles permitting for this jurisdiction?
Lyon County Planning & Zoning Department / Zoning Administrator is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 620-341-3471 (Planning & Zoning); general county office 620-341-4380.
How long might review take?
N/A for ordinary building-permit review. For subdivision-related building permits, the zoning regulations authorize issuance within 30 days after examination of the recorded plat if the application is complete. Zoning permits generally become void after 180 days unless work or the permitted use begins, and a new application is required after a 180-day suspension or abandonment.
How are inspections scheduled?
Use the Lyon County GeoPermits portal to submit and track permits. For floodplain work, the county must verify required state and federal permits before issuing the local permit; contact Planning & Zoning at 620-341-3471 for inspection or floodplain coordination. A separate public inspection-booking schedule was not identified.
Which codes and exemptions should I review?
N/A for a specific current 2026 IBC/IRC edition. The official county permit and zoning materials verify county building permits, zoning regulations, subdivision regulations, and floodplain controls but do not identify a current county technical building-code edition. A county-hosted 2025 regional hazard plan states Kansas’s minimum is the 2006 International Building Code where a jurisdiction has not adopted its own code; this is not a Lyon County-specific adoption notice. The county’s agricultural exemption process allows qualifying agricultural uses to receive an Agricultural Exemption Determination; parcels of 40 or more acres are automatically considered agricultural under the zoning regulations. In flood areas, the county FAQ identifies minor activities such as installing a mailbox post as exempt and says re-roofing generally does not require a floodplain permit. County materials do not publish a complete general building-permit cosmetic-exemption list.
