Most people picture the Grand Strand when they hear Horry County, but the county is far bigger than its beaches — it is the largest county in South Carolina by land area, with farms, timber, and swamp forest stretching inland. The Horry County GIS Application covers all of it, from an oceanfront condo tower to a wooded tract near the North Carolina line.
Conway is the seat; the beach is the headline
County government sits in Conway, a river town on the Waccamaw that is also home to Coastal Carolina University. The coastal strip runs from Little River and North Myrtle Beach through Myrtle Beach to Surfside Beach and Garden City, with fast-growing unincorporated areas like Carolina Forest and Socastee behind it. Loris, Aynor, and a scattering of crossroads communities fill the rural west and north.
You will find the official map on the Horry County line of our South Carolina directory and on the national county map.
Search by address, owner or TMS number
Basic lookup
- Launch the county GIS application in a new tab and give it a moment to load layers.
- Search by address, owner name, or parcel number.
- Click the parcel to see its identification numbers, owner of record, and acreage.
- Toggle aerial imagery to check what is actually on the ground.
Numbers to save
Horry records carry a parcel identification number, and you will also run into TMS numbers — South Carolina’s tax map system reference. Save both along with the owner name as shown; that combination makes calls to the assessor, treasurer, or a title attorney much quicker.
How to find property lines in Horry County
- Find the parcel in the GIS application and note the PIN, the TMS number, and the deed or plat reference if it’s shown.
- Open the county’s online records search from the Register of Deeds. It can search by book and page, so you can pull up the recorded plat.
- Read the plat for lot lines, dimensions and easements, then walk the corners. Rural tracts may have concrete monuments or iron pins.
- Hire a South Carolina licensed surveyor before you build a fence, clear a line, or resolve a dispute.
Beach parcels: condos, HOAs, and dunes
Along the oceanfront, a single parcel can hold a condo building with hundreds of units, so the map polygon may represent the common land while individual units are separate tax accounts. For resort properties, confirm that you are looking at the unit record, not the building footprint. Oceanfront lots also sit near state beachfront jurisdiction lines, which matter for building and rebuilding; the parcel map will not spell out those rules, so check with the appropriate state and local offices.
Horry County acreage map: timber, farms and hunting tracts
West of the Intracoastal Waterway the county turns agricultural. Horry has a long history as a tobacco county, and today you will see row crops, pine plantations, and hunting tracts around Loris, Green Sea, and Aynor. This is where buyers look for five to fifty acres at a lower price per acre than anything near the coast. On the map, look at road frontage, the shape of the tract (long narrow farm parcels are common), and whether wetlands or blackwater creeks cut through it. Our guide to vacant land searches walks through a systematic approach.
Asking permission to hunt or cut a firebreak starts the same way: click the tract to get the owner of record, then reach out politely. For public hunting ground, check the South Carolina Department of Natural Resources’ Wildlife Management Area maps rather than the county parcel map.
Horry County plat book: recorded plats, not a printed atlas
People searching for an Horry County plat book usually want the recorded plat for a subdivision or survey. Those are filed with the Register of Deeds and can be found by book and page in the county’s records search. Viewing is free online. Certified copies come from the office. No current commercial owner-name plat book is sold for the county. The free GIS application does that job, and a South Carolina road atlas covers the back roads. For older land records, the South Carolina Department of Archives and History is the place to look.
Tax map, flood and storm checks
Horry County faces both coastal surge and river flooding — the Waccamaw and Little Pee Dee have flooded low-lying neighborhoods after major storms. Before you fall for any parcel, check the FEMA flood zone and look at how close it sits to the rivers and swamps. The GIS application typically carries flood-related reference layers; confirm the current zone for insurance with official FEMA resources. See flood zones in county parcel viewers for how to read them.
For zoning, Myrtle Beach, Conway and the other cities regulate their own land, and Horry County’s planning department handles the unincorporated areas. Planning staff will ask for the PIN or TMS number from the tax map.
A few quick fixes if the GIS application won’t cooperate: it’s a busy site during storm season, so check back off-peak, and switch to a laptop when you need the layer list. The Horry County line of our South Carolina directory always has the current address.
Who works this map every day
Second-home buyers and retirees comparing neighborhoods, investors screening short-term rental condos, builders chasing lots in Carolina Forest and around Conway, timber buyers, farmers expanding acreage, surveyors, and closing attorneys. Adjacent-owner lookups are common too — our guide to neighboring parcels explains how.
Is the Horry County GIS map accurate?
For finding a parcel and reading its numbers, it’s reliable. For a boundary, it isn’t. The county’s tax map lines are drawn from deeds and plats, and on long, narrow inland farm tracts and swampy timber ground they can be off by a noticeable margin. Beachfront parcels near state beachfront jurisdiction lines deserve extra care. Treat the map as your index to the records, not as a survey.

Frequently asked questions
What is a TMS number in Horry County?
TMS is short for tax map system. It is South Carolina’s tax map numbering. Horry County records also carry a parcel identification number (PIN), so save both when you look up a property.
How do I find out who owns a piece of land with no address?
Zoom to the tract in the county GIS application and click it. The owner of record and parcel numbers appear even when there is no street address.
How do I find a condo unit on the Horry County GIS map?
Search by unit address or owner. The map polygon may show the whole building or its common land, while each unit is a separate tax account.

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.
