The Medina County plat book: start here
In and around Devine, a plat book is a privately published atlas, that map ownership across the countryside, usually township by township.
Opening the official parcel viewer
Your first stop is the appraisal district interactive map; it covers each assessed parcel around Devine and Biry. When a rural tract has no street number, follow the nearest road on the aerial and click the parcel itself, whether the land is near Yancey or elsewhere in the county. For a parcel near Lake Medina Shores, copy the parcel ID from that panel; every records desk in the county asks for it first.
Offices that can help
For assessment questions about property around Lytle belong with the appraisal district, the office behind the parcel record. Questions about what you can build around Devine need the planning or permitting office, and the answer depends on jurisdiction.
Reading the legal description
Tracts outside towns near Lytle are often described by metes and bounds, listing bearings, distances and landmarks. Platted lots around Lytle refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Lytle before you request a deed or survey.
Neighboring parcel maps
Medina County meets Atascosa County, Bandera County, Bexar County, Frio County, and Uvalde County, and each of those keeps its own parcel map. Ground near San Antonio that runs to the line may show up across two assessors' files, so check the neighboring map too. For a parcel near San Antonio, the Platbookmapper state page links every bordering county map across Texas.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Castroville, though signal can drop in rural spots. A screenshot of the parcel near Devine with its ID is a good backup.
Where to look for one
Not every county has a current edition, check with local offices and farm stores near Natalia.
Common uses
Buyers and seed dealers around San Antonio rely on them for a big-picture view of who owns what.
Recorded documents worth pulling
On ground around Yancey, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county sit with the County Clerk. If the land is near Lytle, older tracts in the county may sit on many deeds, so a title company is worth hiring before a purchase.
Making your own township pages
Screenshot each section of the viewer around Devine and keep them in a binder for the truck.
Getting your bearings
Hondo holds the county offices, home to the main records offices. Smaller places on the map include Castroville, Devine, LaCoste, and Lytle, where town lots give way to larger tracts. Around 54,797 people live in Medina County (Census Bureau estimate, 2023) across roughly 1,325 square miles. Medina County dates to 1848, and some chains of title near Bader are long.
Between editions
Between printed editions, the appraisal district interactive map shows current owners, across the county, whether the land is near Natalia or elsewhere in the county.
A word on accuracy
If the land is near Biry, acreage on the record is an assessed number; just a licensed surveyor can set the real boundary on the ground. If the land is near Bader, records update in batches, so a deed recorded last month may not show yet.
Atlas or legal document
For acreage around Devine, a plat book is not a recorded plat: the recorded plat at the County Clerk is a legal document, while the atlas is a reference.
