Lexington County wraps around the south and west sides of Columbia and the southern shore of Lake Murray. Suburban neighborhoods, lake homes and peach and timber country all sit within its borders. OneMap, the county’s GIS viewer, carries an unusual amount of history in its layer list.
Open OneMap, the official Lexington County parcel viewer
OneMap is a county-run Esri viewer with a single locator search and a deep layer list. Parcels and tax map labels are the core, but you can also turn on address points, building footprints, two-foot contours, soils, wetlands, streams, flood zones, school districts, council districts and utilities. Zoning layers cover the county plus the towns of Chapin, Cayce and West Columbia, along with overlay districts such as the Lake Murray residential overlay and an agricultural overlay.
The feature that sets it apart is a set of historic parcel layers, one for each year from 2000 onward. Switching between them shows how a farm was divided or a lot line moved. We link OneMap from the Lexington County entry in our South Carolina list; the Midlands also show up on our clickable county map.
Search by TMS number, address or owner
South Carolina counties identify parcels by tax map number, often called the TMS. In Lexington County, the Property Search tool finds a parcel by owner or address and opens its TMS record with the parcel card, map, owner, deed book and page and chain of title. From there, OneMap shows the parcel in context.
- Copy the TMS exactly, dashes and all, when moving between tools.
- Turn on tax map details if you want to see how the county’s map sheets are laid out.
How to find property lines in Lexington County
- Open the TMS record and note the deed book and page and plat reference.
- Search the Register of Deeds official records for the deed and the recorded plat. The office offers online searching after you register.
- Search each corner for an iron pin; newer subdivisions usually have them.
- Hire a South Carolina professional land surveyor for anything that depends on the exact line.
If the current parcel looks different from what a seller describes, compare it with an older historic parcel layer. A recent split or boundary adjustment often explains the difference.
Lake Murray lots
Lake Murray is a hydroelectric reservoir, and the utility that operates it controls the shoreline above the water line. Private lots along the lake often end at the project boundary rather than at the water, and docks and shoreline work need the operator’s permission. OneMap’s Lake Murray layers and overlay district help, but read the deed and talk with the operator’s lake management office before you buy.
Zoning, overlays and flood layers
Few county viewers put this many zoning overlays in one place. Scenic corridors, transitional buffers, neighborhood appearance districts and airport noise zones can all affect what you build. Turn on the flood zone and flood panel layers along the Saluda and Congaree rivers and the lake’s creeks, and read our note on zoning overlays in a parcel viewer.
Acreage map and hunting land ownership
West of Lexington toward Batesburg-Leesville and south toward Pelion and Swansea, parcels get large and timber is common. OneMap makes a workable acreage map, showing size and ownership for each tract so hunters can contact landowners and get permission in writing. The South Carolina Department of Natural Resources publishes wildlife management area maps for public options.
Towns and fast-growing areas
The town of Lexington and the Red Bank and Gilbert areas south of it have seen steady subdivision growth. Irmo and the Chapin area on the lake’s north side draw families who commute to Columbia, while Cayce and West Columbia hold older neighborhoods along the Congaree River. Out west, Batesburg-Leesville and the county’s farm belt stay rural. Each town sets its own zoning inside its limits, and OneMap’s municipal layer shows where those limits fall. When a parcel sits near a boundary, confirm which government handles permits before you plan construction.
Lexington County plat book
A printed Lexington atlas from a commercial publisher did not surface in our research. The Register of Deeds keeps the recorded plats, and OneMap’s historic parcel layers cover the last two decades and more of changes.
Is the Lexington County GIS map accurate?
OneMap shows a tax map, carefully maintained but not surveyed. The two-foot contours and footprints help you judge a lot, yet the lines are compiled from records. Expect small offsets, and let a surveyor set boundaries, as explained in tax map versus survey.
OneMap not loading?
With so many layers, OneMap can be slow if too many are turned on at once. Turn off the ones you do not need, use a current browser, and clear the cache if the map freezes. Upstate, see our Greenville County guide; all 46 counties are on the South Carolina GIS hub.
Frequently asked questions
What is a TMS number in Lexington County, SC?
TMS stands for tax map number, the identifier South Carolina counties use for parcels. It appears on the tax bill and the parcel record.
Can I see old parcel lines in Lexington County?
Yes. OneMap includes historic parcel layers for each year from 2000 on, so you can compare how lines changed.
Do Lake Murray lots go to the water?
Often not. The lake operator controls a shoreline band, so many private lots end at the project boundary.
Is there a free Lexington County plat book?
OneMap is the closest thing, and it is free, and plats are recorded at the Register of Deeds.

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.
