Property search, parcel maps and data downloads from the appraisal district; the county clerk's deed and plat records; the county and city GIS, floodplain and zoning resources a local search turns up; and the state's survey, oil and gas and soil maps. Each was opened on November 7, 2026. These are where parcel records, deeds, permits and zoning decisions come from.
The Texas Geographic Information Office's statewide StratMap parcel layer is the free source, though it held no parcels for Donley County when we checked it on November 7, 2026.
Only inside city limits. Texas counties have no general zoning power, so unincorporated land in Donley County is unzoned. Unzoned is not unregulated: Texas counties review subdivision plats and septic systems, and most permit development in the floodplain. Each city decides whether and how to zone. The city limits layer shows which city, if any, governs a site, and city planning, GIS and zoning pages are listed under local sources above.
With the county clerk, not the appraisal district. Deeds, plats, easements and other real property records are recorded by the Donley County Clerk; the appraisal district's records and parcel maps are for property tax, and its boundaries are approximate, not a survey. The clerk's office is listed under local sources above. For a property's legal boundary, the recorded plat or a licensed surveyor's survey is the authority.
Rural Texas land is described by its original survey, abstract number, and block and section. The Railroad Commission's public GIS viewer maps survey lines with their abstract numbers across the state, along with oil and gas wells and pipelines, and offers the same layers as free county downloads. The General Land Office holds the original survey and land grant files, searchable by county and abstract number, and 116 historic maps of Donley County, from county maps to surveyors' working sketches. All are listed under local sources above.
3 cities and towns lie mostly inside Donley County: Clarendon, Howardwick and Hedley. The Census Bureau's current boundaries for incorporated places map each one.
FEMA's National Flood Hazard Layer has no countywide digital flood map for Donley County, so it gives no countywide floodplain figure. It may have an older paper map, or none. For a specific property, look up the effective map at FEMA's Map Service Center.
