The Medina County GIS map turns a drive past an empty field near Lytle into a name, a parcel number and an acreage figure.
We'll cover the official map, the communities and terrain around San Antonio, how property lines work in Texas, and where the deeds come from.
Who needs this map
Different people come to the Medina County parcel map for different reasons. If you're after rural acreage near Lytle, the map shows which tracts are big enough and which ones border paved roads or water. Vacant-lot hunters working the edges of Lytle look for parcels with no structures and owners who live out of the area. For a hunter with permission on one farm near LaCoste, the parcel map shows exactly where that permission stops. Contractors working in Medina County use the map to find lot dimensions and neighboring owners before they stake a foundation or schedule a survey.
Opening the Medina County GIS map
Start with the appraisal district interactive map. It's built on a BIS Consulting map viewer and opens in a normal browser. Click a parcel outside Lytle and the pop-up shows the appraisal account, owner and acreage. If the map ever goes missing, check the Medina County, Texas listing on Platbookmapper for the new address.
Medina County at a glance: towns and land
Most of the platted lots cluster in and around Hondo (the county seat) and Castroville, Devine, LaCoste, and Lytle. Out in the countryside, D'Hanis, Lake Medina Shores, and Yancey appear as small knots of lots along the road network. Medina County covers about 1,325 square miles of land; its 2023 population estimate from the Census Bureau was 54,797. Most of the land area is agricultural or wooded, and the parcel lines get bigger and more irregular as you move away from San Antonio.
How accurate are Medina County, TX property lines?
Parcel boundaries on the Medina County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Texas rural land is described by original survey and abstract number, not sections and townships, and the Medina County appraisal map usually shows the abstract lines.

The Medina County economy in brief
Of the 853 establishments the Census Bureau counted in Medina County for 2022, the biggest groups were construction, retail trade, and other services. Relative to the U.S. as a whole, Medina County is heavy on mining (except oil and gas), support activities for mining and drilling, and nonmetallic mineral product manufacturing. A surface parcel near LaCoste may not include the minerals beneath it, which is common where extraction is active. That context helps when you read the parcel pattern around Hondo: jobs and land use move together.
Acreage and vacant lot search
Here's a simple routine for finding open ground in Medina County using the parcel map:
- Start on the outskirts of Devine, where empty lots are easy to spot between the houses on the aerial layer.
- For each tract near Natalia, note the parcel ID, the owner and where the tax bill is mailed.
- Make sure the parcel near LaCoste actually touches a public road, and ask how it's reached if it doesn't.
- Line up the assessed land values of a few neighboring tracts near Devine to sanity-check an asking price.
- Before you sign for land near Devine, check what the local planning and health offices will allow on it.
For a tract near Natalia with no road frontage, see how to tell if land is landlocked.
