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

In unincorporated Richland County, county permitting covers residential and commercial new construction, reconstruction, alteration, repair, building moves and demolition1. Ask Building Permitting and Inspections whether the proposed project needs a permit before hiring a contractor or ordering materials112. South Carolina's mandatory building codes and state modifications must be enforced by every county and municipality12. The currently effective statewide cycle is the 2021 South Carolina Building Codes, which took effect January 1, 202310. A farm structure other than a residence or a structure attached to a residence may qualify for a conditional exemption, but the owner must file the required affidavit before construction, and the exemption does not remove permit authority or floodplain standards9. Qualifying owner-builders remain subject to codes and zoning8.

Who issues building permits in Richland County, SC, and how do you reach them?

Richland County Building Permitting and Inspections handles county building permits and inspections at 803-576-2140, at 2020 Hampton Street in Columbia2. Planning and Development Services answers zoning questions at 803-576-2190 or devservices@richlandcountysc.gov13. Floodplain Management answers flood-map and elevation-certificate questions at 803-576-2172 or flood@richlandcountysc.gov14. Engineering maintains county encroachment-permit records at 803-576-240015.

Inside city limits, Columbia and Forest Acres handle their own building permits1617. Cayce, mainly in Lexington County but reaching into Richland County, also handles its own building permits18. Septic permitting remains with SCDES for homes without public or community sewer, including inside municipalities45.

Does Richland County have zoning?

Richland County administers zoning and land-development regulation in unincorporated areas; municipal jurisdiction or agreements can change the applicable authority3. Columbia, Forest Acres and Blythewood set their own zoning192021. Cayce, mainly in Lexington County but reaching into Richland County, also sets its own zoning22. SCDES still handles septic approval for homes without public or community sewer45.

For county-governed land, minimum lot size and setbacks depend on the zoning district and applicable overlays or development standards; ask Planning and Development Services for the parcel's requirements232413. We could not confirm county building-height or minimum dwelling-size rules; ask the same office before relying on a listing13. Richland County reviews administrative, minor, major and family-heir subdivisions, with floodplain review potentially applying in an A Flood Zone25. State law provides an information-record path for divisions into parcels of at least 5 acres without a new street, but the plat still goes to the planning agency26.

How do septic permits work in Richland County, SC?

SCDES administers septic permitting and installation inspections in Richland County4. A home or manufactured home without public or community sewer needs SCDES site approval and a septic-installation permit before the county can issue a building permit5. Submit the Onsite Wastewater System Application through the state portal with the property's plat or deed and $150 fee; traditional permitting includes a site visit and suitability evaluation27. A Permit to Construct lasts 5 years; renewal or approved changes require a new application and fee5.

Before a new system is covered, the installer must schedule an SCDES inspection28. If the inspector does not arrive within 30 minutes of the scheduled time, a licensed installer may self-inspect and submit the approved final-inspection form2927. State law generally does not require routine inspections of existing systems, but local ordinances may add requirements; ask SCDES about the property2930. Only 26.9% of Richland County soils rate free of severe limitations for conventional drain fields; SCDES considers alternative systems case by case3132.

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

South Carolina provides a building-code pathway for tiny houses through IRC Appendix AQ, but a tiny house must still satisfy Richland County zoning, site-development, building-permit, utility and septic requirements7. We could not confirm the rule for long-term RV living on private land in unincorporated Richland County; ask Planning and Development Services before placing an RV13. County zoning and development standards vary by district, so ask Planning and Development Services for a written, parcel-specific answer before buying or placing an RV or tiny house613. A manufactured home follows a different path: if the property lacks local sewer service, septic approval is required before the county can issue the building permit27. Where a sewer district serves the property, a sewer tap fee must be paid before the county issues the manufactured-home setup permit33. SCDES approval of an alternative wastewater system does not itself approve a dwelling type or off-grid occupancy32. Owner-builder status also does not waive zoning or codes; qualifying owners must personally supervise construction, use licensed help where required and record the statutory notice8.

How do you build a home in Richland County? The steps, in order

  1. Ask Planning and Development Services to confirm jurisdiction, zoning district, allowed residential use and dimensional standards13.
  2. Confirm sewer availability; a home or manufactured home without public or community sewer needs SCDES septic approval before the county building permit27.
  3. If septic is needed, submit the SCDES application, plat or deed and $150 fee, then complete the site evaluation27.
  4. Check floodplain status early; property in a FEMA-designated Special Flood Hazard Area requires a Floodplain Development Permit, generally with the land-development or building-permit application, plus elevation certificates for structures34. Ask Floodplain Management about required elevation certificates and Building Permitting and Inspections for current fees142.
  5. Ask Building Permitting and Inspections what permit and plans the project requires, then apply for review12.
  6. Coordinate access with Engineering because county subdivision review includes road right-of-way and driveway-separation rules3515.
  7. Arrange new septic-system inspection before covering the installation28. Ask Building Permitting and Inspections for residential closeout requirements2. Richland County’s published commercial process issues a certificate of occupancy, posted to the applicant’s online account, only after all requirements and inspections are complete36.

What should you check before buying land in Richland County?

Before making a land contract unconditional, verify the zoning district, sewer availability, septic suitability, floodplain status, subdivision history and legal road access373425. Only 26.9% of county soils rate free of severe limitations for a conventional drain field, so make satisfactory SCDES approval a purchase contingency when sewer is unavailable3127. About 81.3% of the county is wooded and 94.2% has slopes of 15% or less; clearing, drainage and the actual homesite still need parcel-level review3839. The typical home value is $247,539, USDA farmland value is $5,124 per acre, and the median property-tax bill is $1,569 per year404142.

Watch-outs

  • Long-term private-land RV occupancy remains unconfirmed; tiny houses have a statewide building-code pathway but still need parcel-specific zoning and site approval from Planning and Development Services713.
  • Richland County's published fee schedule is labeled 2018 and may have been superseded; ask Building Permitting and Inspections for the current amount before budgeting432.
  • The 2024 South Carolina building-code editions do not begin local implementation until January 1, 202744.
