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.11 A zoning permit and site plan are also required before establishing a new activity or putting up a new building or addition.12 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 [email protected], 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.13 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 has county zoning, and Zoning Administration reviews site plans, issues permits and enforces the zoning ordinance.24 Before a new activity, new building or addition begins, the county requires a zoning permit with a site plan.12 The zoning district matters: park-model trailers, campers and RVs may be used as living accommodations only in districts where that use is listed, and uses not expressly permitted are prohibited.7 A county rule specifically defining tiny homes or setting a countywide minimum dwelling size could not be confirmed; give Zoning Administration the parcel number and proposed unit details before buying or building.212

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.614 The process includes a site evaluation, a Permit to Construct and an inspection before the installed system is covered.315 A Permit to Construct remains valid for 5 years; renewal or modification requires a new application and fee.6 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.16 For application questions, contact SCDES Onsite Wastewater at 1-855-731-2504 or [email protected].17

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 automatically allowed. Park-model trailers, campers and RVs used as living accommodations are allowed only in zoning districts where the use is listed, and unlisted uses are prohibited.7 Campgrounds and RV parks may need special-exception approval, with their structures and construction subject to county permits and inspections.7 A specific tiny-home occupancy rule and countywide minimum dwelling size could not be confirmed, so ask Zoning Administration how the proposed unit is classified and whether the parcel's district allows it.12 The state-park camping limit applies to state-park campsites, not private residential land, so it does not answer this question.18

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.12
  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.196
  1. Submit the county building-permit application, required plans and the applicable construction checklist.13
  1. If acting as owner-builder, personally supervise the work, use licensed contractors where required, sign the disclosure and record the required notice.89
  1. Arrange county building inspections and the SCDES septic inspection before the system is covered.415

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.2516 If the driveway enters a state highway, SCDOT's standard residential access is limited to a 16-foot paved throat and may include a drainage pipe up to 30 inches, subject to safe access and the directive's owner-use conditions.20 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.2122 A private residential well requires a state Notice of Intent and a $70 fee before construction.10

Watch-outs

  • A zoning permit and site plan come before establishing a new activity or constructing a building or addition in Colleton County.12
  • 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.163
  • Current county permit fees and the detailed building-inspection schedule could not be confirmed; request both from Planning & Development at 843-549-1709.4
