Riley County runs this viewer (directly or through a contracted vendor), which makes it the closest thing to the source for local parcel lines. Our October 2026 check found the map open to the public, with no account or payment needed.
Searching for a parcel, step by step
- Open the link to ORKA, the parcel viewer hosted on kansasgis.org that many Kansas counties share.
- Read and accept the intro or disclaimer page to reach the map.
- Search by owner, street address or parcel ID, or click a lot on the map.
- Open the parcel details to see the appraisal information the county shares.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.
