Tarrant County packs more than forty cities around Fort Worth and Arlington. The county’s Public Map Viewer lets you look up a property by address, account or owner and see it against city and lake boundaries.
A county map, not the appraisal site
Tarrant County itself runs this viewer, while the Tarrant Appraisal District keeps the official values and exemptions on its own site. The two work well together. The viewer’s Property Search panel has three tabs, Address, Account and Owner, and the account number it returns is the same one the appraisal district uses. A layer list, a facilities finder, a crime map and a set of portal links round out the tools.
A short notice on the opening screen says the map is for general reference and may change without warning. We list the viewer under Tarrant in our Texas directory, and it is one click away on our county map of the U.S..
Forty-plus cities and their edges
City limits here zigzag. A street can switch from Fort Worth to Haltom City to Richland Hills in a few blocks, and pockets of unincorporated land remain around Lake Worth and the far west. Which city governs a lot decides who issues permits, who picks up trash, and which police department answers calls. Use the layer list to confirm the jurisdiction before you assume anything from a mailing address, since many postal city names cross municipal lines.
How to find property lines in Tarrant County
Almost every urban lot in Tarrant is platted, so the recorded plat is the best starting document.
- Find the account in the viewer and note the legal description: addition, block and lot.
- Search the county clerk’s land records for that addition’s plat and your deed.
- Walk the lot looking for capped iron rods at corners; builders in newer additions often set them.
- For a fence dispute or pool, ask a Texas registered professional land surveyor to stake the line.
If you suspect a utility or drainage strip crosses the back yard, our easement guide covers where those show up.
Gas wells and mineral rights
Tarrant County sits on the Barnett Shale, and during the drilling boom thousands of urban wells were permitted, many on pad sites tucked between neighborhoods. As a result, mineral rights under suburban lots were often leased, pooled or severed years ago. The viewer shows surface parcels only. A title search tells you whether minerals were reserved, and any royalty checks tied to a lease usually follow the mineral owner, not the house.
Lake Worth, Eagle Mountain and Corps lakes
Fort Worth owns Lake Worth and leases many homesites around it, while Eagle Mountain Lake is managed by the regional water district. Benbrook Lake and Lake Grapevine are federal reservoirs where the Corps of Engineers controls the shoreline. So a lot that looks waterfront on the map may border city, district or federal land. Ask which agency governs the shore before planning a dock, and check the viewer’s imagery for how close the line really comes to the water.
North and south growth fronts
Keller, Southlake and Colleyville matured years ago, and building has shifted north toward Haslet and far north Fort Worth, and south toward Mansfield, Crowley and Burleson’s edge. Large master-planned communities there may include public improvement districts or MUD-style assessments. Compare full tax rates on two similar homes before choosing.
Platting outside city limits
Texas cities can review plats in their extraterritorial jurisdiction, a band of unincorporated land around their borders. Since a 2023 state law, many owners in that band can petition to leave it, which changes who reviews a subdivision. On the western and northern edges of Tarrant County, a tract that looks rural may still sit in Fort Worth’s ETJ. Ask the city and the county which rules apply before dividing land or selling off a homesite.
Historic districts in Fort Worth and Arlington
Neighborhoods such as Fairmount, Ryan Place and the Stockyards area carry local historic designations. Exterior changes there typically need a certificate of appropriateness, and demolition gets extra scrutiny. The county map will not flag these overlays, so check the city’s historic preservation pages before planning a remodel on an older lot.
Is the Tarrant County GIS map accurate?
Line work on platted lots usually sits close to reality, since it is drawn from recorded plats. Older areas and large rural tracts in the northwest can be off by more, and aerial photos never align perfectly with parcel lines. The county does not guarantee the map, so rely on a survey for anything that matters legally. What lot lines mean on GIS maps explains why small offsets are normal.

Frequently asked questions
Is the Tarrant County viewer the same as the appraisal district site?
No. The county runs the viewer; the Tarrant Appraisal District maintains official values. Both use the same account number.
Can I search Tarrant County property by owner name?
Yes. The Property Search panel has an Owner tab alongside Address and Account.
Do I own the minerals under my Fort Worth house?
Not necessarily. Minerals were often severed or leased during the Barnett Shale boom, so a title search is the way to find out.
Who controls the shoreline at Lake Grapevine?
The U.S. Army Corps of Engineers manages the federal land around Grapevine and Benbrook lakes.

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.
