Finding Property Lines in South Carolina
Property owners in South Carolina can use several resources to get a general sense of where their boundary lines sit, but only a licensed Professional Land Surveyor can establish the legally accurate location of those lines. Understanding the difference between approximate mapping tools and a formal survey is essential before making any decision that depends on property boundaries.
County GIS and Parcel Mapping
Most South Carolina counties provide online GIS parcel viewers that show property boundaries based on tax assessment data. These tools are free and accessible, and they let you see approximate lot shapes, acreage, and neighboring parcels. South Carolina's Revenue and Fiscal Affairs (RFA) office maintains statewide parcel data that county portals often draw from.
County GIS portals vary in quality. Major counties with strong GIS programs include:
- Greenville County: Greenville County GIS provides detailed parcel mapping with aerial imagery, parcel dimensions, and deed links.
- Lexington County: Lexington County's online mapping shows parcel boundaries, tax data, and access to Register of Deeds records.
- Horry County: Horry County GIS includes parcel viewer, flood zone layers, and aerial overlays useful for the Grand Strand area.
- Berkeley County: Berkeley County GIS parcel viewer with links to tax and ownership information.
- Beaufort County: Beaufort County provides GIS with flood zone overlay, particularly useful in this coastal county.
- Spartanburg County: Spartanburg County GIS with parcel search and tax mapping.
- York County: York County GIS viewer with parcel boundaries for the Rock Hill and Fort Mill areas.
These tools show approximate tax parcel boundaries only. They are not survey-accurate and should not be used to determine legal property lines for construction, fencing, or litigation.
Register of Deeds and Recorded Plats
The definitive source for your property's legal description is the deed, which is recorded at your county's Register of Deeds (called the Register of Mesne Conveyances in Beaufort, Berkeley, Charleston, and a few other Low Country counties). Your deed references a recorded plat book and page or a metes-and-bounds description.
If your property was created from a recorded subdivision plat, that plat shows the lot's shape, dimensions, and relationship to adjacent lots and public roads. Many SC county Registers of Deeds have online deed and plat indexes where you can search by owner name or parcel number. Older plats may only be available in physical form at the courthouse.
Physical Monuments on the Ground
If a prior survey was done on your property, the surveyor would have set iron pins, rebar, concrete monuments, or other markers at the corners. These may still be in place. You can walk your boundary and look for these markers, but be aware that monuments can be buried, moved, or destroyed over time, particularly in areas that have undergone development or grading. If you find a marker, it may or may not represent your actual corner without verification by a licensed surveyor.
When to Hire a Licensed Surveyor
For any decision that depends on precise boundary location, hire a licensed South Carolina PLS. Common situations include fence installation near a property line, building a structure within required setbacks, resolving a boundary dispute with a neighbor, preparing for a lot split or subdivision, or buying rural land where the deed description is a metes-and-bounds description rather than a recorded plat.
Only a boundary survey performed by a licensed PLS produces a legally defensible determination of where your property lines are in South Carolina.
