If a legal description for land in Galveston cites a lot number, you'll need the Galveston plat map to make sense of it. This Galveston guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Galveston plat map
For a lot near Hitchcock, the deed usually cites the plat; bring that to the recorder's office or its online index.
Opening the official parcel viewer
Go first to the Galveston County ArcGIS parcel map; it maps every assessed parcel from Bayou Vista to La Marque. For a home near Tiki Island, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Around Santa Fe, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Where Galveston fits in
Galveston sits in Galveston County, Texas, and the county assessor maps its lots. As the county seat, Galveston hosts the courthouse, handy when you need recorded documents. Closer to Bayou Vista, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits near La Marque often answers to county rules rather than the town's.
When there's no plat
Acreage around Tiki Island outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Plat map vs. parcel map
The Galveston County ArcGIS parcel map draws parcels for taxes, but the recorded plat is what the deed relies on.
When a plat changes
An amended plat may change lots around Bayou Vista, so check for later filings; vacated streets or alleys also get recorded.
Offices that can help
If the acreage or value on a parcel near Santa Fe looks off are handled by the appraisal district, since that office keeps the assessment data. Questions about what you can build around Jamaica Beach are for the local planning and health departments, town or county, depending on location.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Tiki Island, so load it before you lose signal. A saved image of the lot near Hitchcock and its lines is a good backup.
Details on the Galveston plat map
Recorded easements around Hitchcock can block a shed or pool; read the notes on the sheet.
What the map can't tell you
The acreage figure is a tax-roll number; just a licensed surveyor establishes the real corners on land around La Marque. Owner names and values update on a schedule, so a recent sale near Jamaica Beach might lag behind.
How land is described here
Tracts outside towns near Hitchcock are often described by metes and bounds, which trace the boundary call by call. Town lots near La Marque are typically described by lot and block, making them easier to find. Copy the legal description from the record for the parcel near Tiki Island before you request a deed or survey.
Requesting the plat
Out toward La Marque, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
Neighboring parcel maps
Galveston County borders Brazoria County, Chambers County, and Harris County; every one of them runs a separate parcel map. Acreage along the edge near Jamaica Beach can be split in two county records, so look at the neighboring map before you assume the acreage. On ground around Bayou Vista, our state page lists each bordering county map for Texas.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Bayou Vista are filed with the County Clerk. Inherited tracts near Hitchcock may sit on many deeds, so a title company can sort it out on a real sale.
Places you'll see on the map
The city serves as the county seat, which is where the courthouse records live around Clear Lake Shores. You'll also find Jamaica Beach, Hitchcock, Tiki Island, and Bayou Vista, each with its own cluster of lots. About 361,744 people call Galveston County home (Census estimate, 2023) across about 379 square miles. Galveston County was formed in 1838, and some chains of title near Tiki Island are long. Features like Clear Lake make handy reference points on the map near Jamaica Beach.

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.
