When a deed near Lake City says lot and block, you'll need the Mathis plat map to make sense of it. In this Mathis guide: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Tracking down the Mathis plat map
For a lot in Mathis, the deed usually cites the plat; that makes the request quick.
Pulling up a parcel
Your first stop is the San Patricio CAD interactive map; it includes every assessed parcel around Sinton and Corpus Christi. Out toward Aransas Pass, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Lake City, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Where Mathis fits in
Mathis is part of San Patricio County, Texas, and the county assessor maps its lots. Out toward Lake City, City or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Lakeside usually answers to county rules rather than the town's.
Offices that can help
For assessment questions about property around Lakeside belong with the appraisal district, since that office keeps the assessment data. Building or septic questions for a lot near Sinton go to planning, building or health offices, town or county, depending on location.
Two different maps
The San Patricio CAD interactive map draws parcels for taxes, while the recorded plat is the legal document.
Replats and vacations
An amended plat may change lots around Odem, so check for later filings; street vacations show up in the records too.
Reading the plat sheet
Out toward Sinton, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
What the map can't tell you
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Sinton can sit a few yards off the line on screen. For a parcel near Odem, records update in batches, so a deed recorded last month might lag behind.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements for land near Sinton are filed with the County Clerk. In and around Lakeside, have ready the instrument number listed on the parcel record so staff can find the deed fast.
Neighboring parcel maps
San Patricio County meets Aransas County, Bee County, Jim Wells County, Live Oak County, and Nueces County; every one of them runs a separate parcel map. A tract near the line by Odem can be split in two county records, so check the neighboring map before you assume the acreage. For acreage around Sinton, our state page links every bordering county map for Texas.
Ordering the Mathis plat map
Out toward Odem, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
Metes and bounds instead
Acreage around Odem outside a subdivision may have no plat at all; look for a recorded survey for land near Sinton.
A quick look at the area
Sinton serves as the county seat, where most land records are kept. You'll also find Lakeside, Lake City, and Odem, where town lots give way to larger tracts. About 70,660 people live in San Patricio County (Census Bureau estimate, 2023) on about 693 square miles. San Patricio County was organized in 1836, which matters when you trace an old farm's title.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Lakeside, but coverage can be spotty out of town. A screenshot of the parcel near Sinton with its ID helps when you meet an owner or agent.
Reading the legal description
Tracts outside towns near Odem commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Sinton are typically described by lot and block, making them easier to find. Keep the legal description for land near Sinton when you talk to a surveyor.
