Yes, but water will be the challenge. Only about 20 inches of rain falls a year, so you will rely on a well (near 210 feet here) or hauled water. The sun is strong, about 6.2 hours of full sun a day, so a smaller solar array covers a household. Texas counties cannot zone rural land, so there is no county zoning to clear.
What the land says
Rain
Too dry to live on rain. Plan on a well, and on irrigating anything you grow.
About 20 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 210 feet deep; a well typically runs $8,000 to $17,000
Growing season
A full season for most vegetables.
About 186 frost-free days, USDA zone 7a; last frost about April 18, first about October 22
Sun
Strong sun. A modest solar array covers a household.
About 6.2 hours of full sun a day, averaged over the year
Flood
Flood zones are rare here. Still, look up the parcel on FEMA's flood map.
FEMA maps no flood zones nearby
Wildfire
Low wildfire risk.
U.S. Forest Service wildfire hazard map: Very Low to Moderate here
Storms
Hurricanes and strong tornadoes are rare here.
NOAA: no hurricane-strength storm within 50 miles since 1975; about 1 strong (EF2 or stronger) tornado a decade within 25 miles
Terrain
Flat to gentle, easy to build on.
Slopes average about 1%, about 3,490 feet above sea level
Soil
Good ground for a standard septic system. The county's soil test decides.
Clay loam, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000
Road
Paved roads are close by.
Nearest paved road usually within about 0.6 miles (OpenStreetMap)

Is it legal here?
Zoning
None. Texas counties cannot zone rural land, though septic, well, and floodplain rules still apply.
Building code
Texas state law applies the International Residential Code only inside city limits, so a house on unincorporated county land usually has no building code or permit. A county may opt in to require it, checked by an inspector the builder hires, but it cannot require approval before you build or charge a fee.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.
Water rights
A mix of two systems. Ask the state water office before you drill a well or dam a creek.
Drilled to about 210 feet, with pump and pressure tank
Septic
$5,000 to $10,000
Standard system
Solar and batteries
$20,000 to $35,000
Sized for a modest household
Road or driveway
$2,000 to $7,000
From the nearest road to a house site
Clearing
$1,000 to $3,000
A house site, solar, and garden
Total
$36,000 to $71,000

Deed rules
Order a title search for deed restrictions.
With no county zoning, deed restrictions and subdivision rules decide what you can build.
Soil test
Get a soil test before you count on septic.
The county has to approve the ground before it issues a septic permit.
Road access
Confirm the parcel fronts a public road or has a recorded easement.
Without one, you may not have a legal way in.
