Searching for a Duval County GIS map usually means you have a specific piece of ground in mind: a listing near Benavides, a woodlot you drive past, or the lot next door.
Duval County at a glance: towns and land
Most of the platted lots cluster in and around San Diego (the county seat) and Benavides and Freer. Unincorporated spots like Concepcion, Realitos, and Ramirez are worth a look if you want rural acreage near a crossroads community. The county dates to 1876, named for Burr H. Duval, and older deeds may still refer to landmarks from that era. About 9,604 people lived in Duval County in 2023, according to Census Bureau estimates, on roughly 1,793 square miles. Click anywhere between Benavides and Freer and you are likely to land on a big ranch, farm or timber parcel rather than a house lot.
Work and land use in Duval County
Census business counts for 2022 list 139 establishments in Duval County; retail trade tops the list, with accommodation and food services and mining, quarrying and oil and gas close behind. Measured against national shares, pipeline transportation, support activities for mining and drilling, and mining (except oil and gas) are overrepresented in Duval County. Ranch and farm tracts around Benavides can carry separate mineral ownership, so read the deed before you price the surface.
Opening the Duval County parcel viewer
Start with the Duval CAD interactive map. It's built on a BIS Consulting map viewer and opens in a normal browser. Search a Freer address or an owner, and the map zooms to the account with its property ID and legal description. If the map ever goes missing, check the Duval County, Texas listing on Platbookmapper for the new address.
Acreage and vacant lot search
Looking for open ground between San Diego and Benavides? Try this:
- Zoom out over the countryside around San Diego with the aerial layer on, and look for parcels with no structures.
- Open the record for each empty tract near San Diego and note whether the owner's mailing address is outside Duval County.
- Assessed values lag the market, but comparing tracts near Rios still shows which ones the county rates higher.
- Measure the road frontage on the map; a sliver of frontage on a road outside Benavides may not be enough for a driveway permit.
- Check the flood layer and ask about septic and permits; open land in Duval County isn't automatically buildable.
For a tract near Benavides with no road frontage, see how to tell if land is landlocked.

Reading property lines on the Duval County GIS map
A Duval County GIS map is built for assessment, not construction. In Duval County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. Texas rural land is described by original survey and abstract number, not sections and townships, and the Duval County appraisal map usually shows the abstract lines. A survey is the only document that settles where a Duval County boundary actually runs.
Where Duval County deeds and plats are kept
Behind each Duval County parcel is an assessment by the appraisal district and a deed recorded with the county. For a tract near San Diego, the appraised value is set by the Duval County appraisal district, which Texas law keeps separate from county government. For subdivision lots in Benavides, the plat book and page on the record leads straight to the recorded plat.
