Want a copy of the Dimmit County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Big Wells. This Dimmit County guide covers: what's in a plat book, where to look for printed copies, and how the county viewer fills the gaps.
Getting started with the Dimmit County plat book
If you're looking near Big Wells, a plat book is a privately published atlas, with owner names on each tract, usually township by township.
Getting to the right map
Your first stop is the Dimmit CAD interactive map; it includes every assessed parcel from Carrizo Springs to Carrizo Hill. For a parcel near Las Vegas, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Las Vegas, save the parcel ID from that panel; each office in the county uses it to find the file.
Finding a printed edition
Libraries near Carrizo Springs sometimes keep past atlases, useful for family or title research.
How land is described here
Rural deeds near Asherton are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Carrizo Springs usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Carrizo Hill before you request a deed or survey.
Common uses
Farmers, hunters and appraisers near Brundage use plat books to see ownership across many tracts at once.
The paper trail behind a parcel
Before you sign anything, get the recorded deed from the County Clerk; the viewer just points to it, for land near Las Vegas included. If you're looking near Brundage, use the book and page shown in the record panel to skip a name search.
