Knox County's own maps and records

Common questions about Knox County

01Where can I find a Knox County parcel map and parcel data?

Free, from the source. The Texas Geographic Information Office's statewide StratMap parcel layer carries Knox 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.

02Does Knox County have zoning, and where is the zoning map?

Only inside city limits. Texas counties have no general zoning power, so unincorporated land in Knox 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.

03Where are Knox County deed and plat records?

With the county clerk, not the appraisal district. Deeds, plats, easements and other real property records are recorded by the Knox 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.

04How do I find the original survey or abstract for land in Knox County?

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 137 historic maps of Knox County, from county maps to surveyors' working sketches. All are listed under local sources above.

05Which cities are in Knox County?

4 cities and towns lie mostly inside Knox County: Munday, Knox City, Benjamin and Goree. The Census Bureau's current boundaries for incorporated places map each one.

06Where is the Knox County flood map, and how much is in a flood zone?

FEMA's National Flood Hazard Layer has no countywide digital flood map for Knox 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.

07Where are the high-voltage transmission lines in Knox County?

HIFLD maps 141 miles of transmission line inside Knox County: 105 mi at 138 kV and 35 mi at 345 kV. It marks 73 of those miles in service and records no status for the rest. The live map colours each line by voltage.

08What is the median household income in Knox County?

$56,304, against $76,292 for Texas (ACS 2019–2023 5-year estimates). Across its 2 census tracts (2020 boundaries), tract medians run from $43,750 to $59,457.
