Parcel lines, owner names and acreage for every tract from Carlisle to Lockhart are a few clicks away on the Union County plat map, and it costs nothing to use.
Keep reading for the viewer link, how to search it, what the parcel data means, and how deeds and plats back it up in Union County.
Getting into the Union County Beacon site
Parcels from Lockhart to Monarch Mill are on the Union County Beacon site, which the county runs on Schneider Geospatial's Beacon platform. Search a Lockhart address or an owner name on the search page, then jump to the map view to see that parcel's lines. If the map ever goes missing, check the Union County, South Carolina listing on Platbookmapper for the new address.
Property lines in Union County, South Carolina
Zoom in far enough on a lot in Carlisle and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Out toward Monarch Mill, boundaries follow bearings and old landmarks rather than a grid, and the parcel layer shows it. A survey is the only document that settles where a Union County boundary actually runs.
Union County at a glance: towns and land
Most of the platted lots cluster in and around Union (the county seat) and Carlisle, Jonesville, and Lockhart. Census Bureau estimates show 26,629 residents in 2023 and around 514 square miles of land in the county. It's a middle-density county, so the map shifts from small platted lots near Carlisle to farm and wooded tracts within a few miles. Public ground such as Sumter National Forest and Thurmond Tract Wildlife Management Area appears as large unbroken blocks, and the private parcels around them draw hunters and recreation buyers.
Private and public hunting ground in Union County
Before you scout a new spot near Lockhart, pull up the parcel layer and see how many owners share that stretch of woods. Around Sumter National Forest and Thurmond Tract Wildlife Management Area, private tracts can press right up against the public boundary, so check the lines before you walk in. Seasons, licenses and public hunting areas are set by the South Carolina Department of Natural Resources, so check their rules and maps too. Landowners in Union County hear from a lot of hunters; a specific request that names the parcel stands out.
Using the Union County plat map to find vacant land
A vacant-land search near Carlisle, step by step:
- Zoom out over the countryside around Jonesville with the aerial layer on, and look for parcels with no structures.
- A tax bill mailed far from Monarch Mill usually means an absentee owner, so note the mailing address on each record.
- Compare land values on similar Union County tracts to see whether an asking price is in the ballpark.
- Make sure the parcel near Jonesville actually touches a public road, and ask how it's reached if it doesn't.
- Before you sign for land near Lockhart, check what the local planning and health offices will allow on it.

Where Union County deeds and plats are kept
Every line on the Union County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Names differ across states, so confirm on the official Union County site which office records deeds and plats. The parcel record often lists a deed book and page or an instrument number, which is how you request a copy of the recorded deed for a tract near Carlisle.
Who needs this map
Land shoppers looking between Carlisle and Jonesville measure road frontage on the map and check whether a tract is landlocked. Unlisted land near Jonesville sometimes turns up this way: an empty parcel, an absentee owner, and a polite letter. A small builder looking for spec lots around Lockhart can scan the map for vacant parcels in already-platted subdivisions.
Two things the map won't tell you
If a tract near Lockhart changed hands recently, the recorded deed is more current than the map. Acreage on the Union County map is a tax figure; a survey is what a lender or buyer should rely on.
Work and land use in Union County
Federal business data for 2022 shows 412 establishments in the county, with retail trade, other services, and accommodation and food services at the top of the list. The sectors that stand out against the national mix are textile mills, forestry and logging, and plastics and rubber products manufacturing. Around Carlisle, a wooded tract on the map may be a working forest; recent aerials and the deed will show whether timber rights were reserved. That context helps when you read the parcel pattern around Jonesville: jobs and land use move together.

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.
