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.
Free, from the source. The Texas Geographic Information Office's statewide StratMap parcel layer carries Presidio County's parcels from the county appraisal district, tax year 2026, collected in March 2026. The appraisal district's own property search and parcel map are listed under local sources above. TxGIO's DataHub also offers the county's parcels as a free shapefile download. Data resellers charge for copies of the same records. Add the layer to a Felt map by URL to filter, measure and share parcels with your team.
Only inside city limits. Texas counties have no general zoning power, so unincorporated land in Presidio 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.
With the county clerk, not the appraisal district. Deeds, plats, easements and other real property records are recorded by the Presidio 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 607 historic maps of Presidio County, from county maps to surveyors' working sketches. All are listed under local sources above.
2 cities and towns lie mostly inside Presidio County: Presidio and Marfa. 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 Presidio 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.
