Does Hampton County have zoning?

Hampton County's Unified Land Development Ordinance applies in unincorporated areas, except land within the specified Lowcountry Regional Industrial Park; the county ordinance does not establish zoning authority inside incorporated municipalities2. A detached house or a mobile home on its own lot requires at least 10,000 square feet; a parcel without public sewer must also meet the applicable onsite-wastewater area requirement2. For a single-family or mobile home, the front setback is 30 feet on a minor road, 40 feet from a collector right-of-way and 50 feet from an arterial right-of-way; the side setback is 10 feet and the rear setback is 25 feet2. Residential impervious surfaces—including buildings, driveways and pavement—may cover no more than 55% of the base site area2. Accessory uses may occupy required setbacks but not required buffers, and corner-lot, intersection and livestock modifications apply; ask Building & Planning to confirm the buildable area2,3.
Estill has town zoning; SCDES still handles septic approval where public or community sewer is unavailable4,11.
How do septic permits work in Hampton County?
SCDES administers onsite wastewater approval and inspection in Hampton County.
SCDES administers onsite wastewater approval and inspection in Hampton County4. Where public or community sewer is unavailable, a home or manufactured home needs SCDES approval and a septic installation permit before the county can issue its building permit; the permit is valid for five years, while renewal or modification requires a new application and fee4. The residential application fee is $15012. Only 13.6% of Hampton County soils are rated without severe limitations for a conventional drain field, so make approval a purchase contingency13. Before covering the system, the installer must schedule an SCDES inspection14. Alternative off-grid sanitation was not confirmed, so ask SCDES about the proposed system before designing around it15. For pre-application questions, call 1-855-731-2504 or email OSWWCentral@des.sc.gov15.

Hampton County defines RV parks and campgrounds as temporary living quarters for recreation, education or vacation, but that rule does not authorize permanent RV living on an ordinary private lot2. We could not confirm a county rule for temporary camping or long-term RV occupancy outside a regulated park; ask Building & Planning whether the parcel's district allows an RV during construction3. We also could not confirm a special tiny-home rule or minimum dwelling floor area; a tiny home treated as new construction remains subject to permits, zoning, minimum lot area and setbacks1,2. A manufactured home built before June 1976 cannot be placed in Hampton County, and one more than 15 years old requires Building Official approval and supporting documents2.

Check septic feasibility before closing: only 13.6% of Hampton County soils are rated without severe limitations for a conventional drain field13. Confirm the zoning district, road class, setbacks and residential impervious-surface cap with Building & Planning2,3. A detached home lot has a 10,000-square-foot floor, but land without public sewer must also satisfy the applicable onsite-wastewater area requirement2. If the tract will be split, Hampton County regulates exempt, minor and major subdivisions through different review paths2. For a subdivision in a designated flood-hazard area, plats must show adequate protection from inundation without appreciably expanding flood-prone areas; protective works require compensating waterway, ditch or basin adjustments2. If access meets a state highway, SCDOT approval applies within the state right-of-way16. Farm structures may qualify for a building-code exemption, but the owner must file an affidavit before construction and flood standards still apply8.

- A detached home lot must have at least 10,000 square feet, and a parcel without public sewer may need more land to satisfy onsite-wastewater requirements2.
- A parcel's road classification changes the single-family front setback, while a 10-foot side setback and a 25-foot rear setback also apply2.
- Flood-hazard subdivisions in unincorporated Hampton County require flood-protection plans, drainage and utilities designed to minimize flood damage; the county ordinance exempts the specified Lowcountry Regional Industrial Park2.
- The RV-park rules describe temporary lodging, but long-term RV use on an ordinary lot, tiny-home treatment and minimum dwelling floor area remain unconfirmed; ask Hampton County Building & Planning for a written parcel-specific answer2,3.
- South Carolina's 2024 code editions take effect for local jurisdictions on January 1, 2027, so confirm which code cycle governs a project spanning that date3,17.
