When land near Devine catches your eye, the San Antonio GIS map shows parcel boundaries plus basic tax data. What this San Antonio guide covers: where that map lives, the fastest ways to search, and what to double-check with records.
Where the San Antonio GIS map lives
Parcel maps here are usually run by the county, not the town, which makes the appraisal district interactive map the main source for lots in San Antonio.
Getting to the right map
Lots and tracts near LaCoste can be looked up on the appraisal district interactive map, free to use and open without a login. In and around LaCoste, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Natalia, the record panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
San Antonio, TX: the basics
San Antonio sits in Medina County, Texas, so its parcels are on the county's map. For a parcel near Castroville, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits out by Castroville often follows county rules instead.
Browser tips
If the viewer stalls on a phone near Hondo, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
Field tips
Most viewers work in a phone browser, useful out on a road near Natalia, but coverage can be spotty out of town. A saved image of the lot near Natalia and its lines keeps working without signal.
Next door to Medina County
Medina County borders Atascosa County, Bandera County, Bexar County, Frio County, and Uvalde County, and each of those keeps its own parcel map. Acreage along the edge near Lytle can show up in two county records, so open the neighboring map too. For land near LaCoste, our state page lists each neighboring county map across Texas.
Searching the map
Vacant ground near LaCoste may lack an address, so zoom in from the nearest road and click the outline. On ground around Devine, searching by parcel number never misses, and you'll find it on tax statements.
A word on accuracy
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near LaCoste may sit several feet off the line on screen. In and around Castroville, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Beyond the parcel lines
For acreage around Natalia, layer lists often include municipal boundaries, floodplain and sometimes zoning; availability varies.
Saving what you find
Print or screenshot the parcel near Castroville with its ID visible, so you have it when calling an office.
Owner, value and acreage
Recent sales on nearby lots near Devine give a rough idea of values; they're not an appraisal.
A quick look at the area
Hondo is the county seat, home to the main records offices. Smaller places on the map include Castroville, Devine, and LaCoste, where town lots give way to larger tracts. About 54,797 people call Medina County home (Census Bureau estimate, 2023) spread over roughly 1,325 square miles. Medina County was organized in 1848, and some chains of title near Natalia are long.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Lytle are kept by the County Clerk. Long-held tracts around Devine can sit on several deeds, so a title company can sort it out if money is changing hands.
Legal descriptions in Texas
Older tracts around Hondo are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Hondo refer to a recorded plat, making them easier to find. Write down the legal description for the tract near Hondo before you request a deed or survey.
Offices that can help
If the acreage or value on a parcel near Hondo looks off go to the appraisal district, which maintains the tax roll. Zoning, permits and septic questions near Devine are for the local planning and health departments, depending on whether the land is inside town limits.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
