Colorado–Kansas Border Counties: Parcel Maps on Both Sides
All 13 counties on the Colorado–Kansas line, with seats, 2023 populations and a link to each official parcel map, plus what changes at the state line.
Looking for the counties on the Colorado–Kansas border and their parcel maps? According to the Census Bureau's county adjacency file, 6 Colorado counties touch 7 Kansas counties along the line. Each one keeps its own property records and its own parcel viewer, so land near the line often means checking two counties in two states.
A farm, hunting tract or lake lot can sit in one state while the road, the neighbors or the rest of the property are in the other. This page lists every county that touches the line on either side, with links to each official parcel map.

Which counties face each other
The Census adjacency file pairs counties that share a boundary. Use it to find the county across the line from the one you know:

- Cheyenne County, CO borders Greeley County, KS, Wallace County, KS
- Kiowa County, CO borders Greeley County, KS
- Kit Carson County, CO borders Cheyenne County, KS, Sherman County, KS, Wallace County, KS
- Prowers County, CO borders Greeley County, KS, Hamilton County, KS, Stanton County, KS
- Yuma County, CO borders Cheyenne County, KS
What changes when you cross the line
- Different viewers. On the Colorado side the official maps run on: no verified public viewer listed yet (2); ArcGIS Experience Builder (1); qPublic (Schneider Geospatial) (1); Beacon (Schneider Geospatial) (1); Colorado Public Parcel Map (1). On the Kansas side: ORKA (Kansas) (7). Search boxes, parcel ID formats and the details shown in pop-ups will differ.
- Different records offices. Deeds, plats and tax bills are kept by the county where the parcel sits.
- Different rules. Zoning, septic permits and property tax are set locally and by each state, so check with the county on the side where you plan to build or buy.
Researching a tract that crosses the line
- Find the parcel in both counties' viewers. Each side will show only its own piece, with its own parcel number.
- Pull the recorded deed from each county's register or recorder, since each county records only the land inside its own boundary.
- Expect two tax bills, one from each county, and check each state's rules for homestead or farm exemptions.
- For a sale, a fence or a building permit, hire a licensed surveyor familiar with the line; tax-map lines are drawings, not surveys.
A quick way to check which side a spot is on
Open the official parcel viewer for the county you think the spot is in (linked in the tables above) and search the address or zoom to it. County-run parcel layers usually stop at the county line, so if no parcel comes up there, check the viewer for the county across the line. A statewide viewer shows both sides, so read the county name in the parcel details.
