Towns in Lee County: Bishopville.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Lee County has 58 FIRM panels, the newest effective November 2008; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Lee house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the county GIS parcel layer (each South Carolina county publishes its own; the state has no statewide parcel map), so a Lee lot shows the same lines the county assessor draws. Lee County covers about 262,519 acres of land and 669 acres of water.
Mapped lines are approximate. The Lee County county assessor keeps the parcel record (Lee County website); a licensed surveyor sets the true corners.
Zoning
Lee County zones its unincorporated land, and Bishopville zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
The South Carolina Local Government Comprehensive Planning Enabling Act (Title 6, Chapter 29) lets local governments allow an accessory dwelling unit on a lot with a house. Whether a Lee lot can add one depends on its district; the county planning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Lee County is soil survey area SC061, Lee County, South Carolina, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Lee County needs a permit from the SC Department of Environmental Services onsite wastewater program for Lee County, which tests the soil on the lot itself.
Setbacks
Setbacks in Lee County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the county zoning office gives them for the lot's district, and Bishopville for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Lee lot and the Forest Service wildfire hazard rating at it.
