#5 of 46 in South Carolina

Unincorporated Colleton County, South Carolina typically requires construction plans and a building permit for construction, and the county also permits mobile-home placement1. Colleton County zoning applies outside municipalities, while the South Carolina Department of Environmental Services handles septic approval for land without public or community sewer23. Start with Colleton County Planning & Development because zoning approval, and floodplain approval where applicable, can come before the building application45.

Do you need a building permit in Colleton County, South Carolina?

Yes, for typical construction in unincorporated Colleton County. The county says construction plans and a building permit are typically required, and its Building Permitting & Inspections function issues permits for all construction activity and mobile-home placement.14 The county enforces adopted building codes in unincorporated areas, including the statewide-modified residential and building codes.13 A zoning permit and site plan are also required before establishing a new activity or putting up a new building or addition.14 We could not confirm which minor repairs might be exempt, so describe the exact work to Planning & Development before assuming a small project can proceed without a permit.4

Who is the Colleton County building department, and how do you reach it?

Colleton County Planning & Development is the building department for unincorporated Colleton County, covering building permits and inspections as well as planning, zoning, floodplain management and code enforcement.4 The office is at 31 Klein Street, Harrelson Building, Room 300, P.O. Box 98 Walterboro, SC 29488; call 843-549-1709, email planning@colletoncounty.org, or call 843-549-1844 for inspections.4 The county publishes a building-permit application and construction checklists, while plans and a permit are typically required.15 Current permit fees and the precise inspection sequence could not be confirmed, so ask the office for both when you describe the project.4

Does Colleton County have zoning?

Yes. Colleton County zoning applies in the unincorporated portions of the county, and municipalities may have separate zoning rules2. Zoning Administration reviews site plans, issues permits and enforces the zoning ordinance, and the county publishes a zoning map and a Title 14 ordinance with nine base districts4616. Before a new activity, new building or addition begins, the county requires a zoning permit with a site plan14. Dimensional rules differ by district. In the RC-1 district, the table lists a 5-acre minimum lot, 150-foot minimum width, 35-foot front setback, 20-foot side setback, 50-foot rear setback and 40-foot maximum structure height171819. Manufactured homes on individual lots are a conditional use in RC-1, and other districts may differ20. A countywide minimum dwelling size could not be confirmed; give Zoning Administration the parcel number and proposed use before buying or building14.

How do septic permits work in Colleton County?

For a new home or manufactured home on Colleton County land without public or community sewer, SCDES must approve the site and issue a septic permit before construction or placement, and the county cannot issue the building permit first.721 The process includes a site evaluation, a Permit to Construct and an inspection before the installed system is covered.322 A Permit to Construct remains valid for 5 years; renewal or modification requires a new application and fee.7 Only 5.9% of county soils rate without severe limitations for a conventional drain field, so make septic feasibility an early contract contingency rather than assuming a standard system will work.23 For application questions, contact SCDES Onsite Wastewater at 1-855-731-2504 or OSWWCentral@des.sc.gov.24

Can you live in an RV or tiny home on your land in Colleton County?

Colleton County does not treat private-land RV living as a permanent right. The zoning ordinance allows park-model trailers, campers and RVs as temporary housing in all districts unless restrictive covenants prohibit them, for up to one year such as during construction of a permitted residence, with a six-month extension possible from the zoning board of appeals8. Conditions include one unit per lot, a road-ready unit with wheels, axles and hitch, no permanent foundation, no renting it out for income, and electrical service of no more than 100 amps after a septic system is installed8. Placement as a principal use is prohibited on Edisto Island8. Separately, living in an RV on an individual lot is a special exception in the RC-1 district9. The ordinance does not define tiny homes, and these units are not recognized as permanent dwellings under the residential code8. Temporary hunting and fishing camps are district-regulated uses, while campgrounds and RV parks may need special-exception approval25. Ask Zoning Administration how the proposed unit would be classified14.

Building a home in Colleton County: the steps, in order

  1. Ask Zoning Administration to confirm the parcel's district and submit the zoning permit application with a site plan.14
  1. Ask Floodplain Management whether the parcel is in a flood-hazard area; all development in the floodplain requires a permit.5
  1. Verify sewer availability, and if public or community sewer is unavailable, obtain SCDES site approval and a septic Permit to Construct before the county building permit.267
  1. Submit the county building-permit application, required plans and the applicable construction checklist.15
  1. If acting as owner-builder, personally supervise the work, use licensed contractors where required, sign the disclosure and promptly record the required notice with the register of deeds; sale or rent within two years of completion is presumed to defeat the exemption.1011
  1. Arrange county building inspections and the SCDES septic inspection before the system is covered.422

What should you check before buying land in Colleton County?

Start with the zoning district, flood status, legal access, sewer availability and a septic contingency. Zoning controls the allowed use, all floodplain development needs a county permit, and only 5.9% of county soils rate without severe limitations for a conventional drain field.27523 If a seller proposes creating or replatting lots, confirm the approval path with Planning & Development because the department reviews subdivisions and plats in unincorporated Colleton County.28 Colleton County's median property-tax bill is $883 per year and its effective property-tax rate is 0.6%, but verify the actual parcel assessment before closing.2930 A private residential well requires a state Notice of Intent and a $70 fee before construction, and the driller must notify SCDES 48 hours before installation.12

Watch-outs

  • A zoning permit and site plan come before establishing a new activity or constructing a building or addition in Colleton County.14
  • All development in a mapped floodplain—not only buildings—requires a county floodplain permit.5
  • Only 5.9% of Colleton County soils rate without severe limits for a conventional drain field, so obtain the SCDES site evaluation early.233
  • Current county permit fees and the detailed building-inspection schedule could not be confirmed; request both from Planning & Development at 843-549-1709.4
