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

Yes. Unincorporated Berkeley County requires a valid permit before work governed by its adopted technical codes begins, and the permit card must remain posted visibly at the site during construction1. The county adopts the code editions most recently adopted by the South Carolina Department of Labor, Licensing and Regulation, subject to exclusions in the county ordinance11. The current mandatory statewide editions are the 2021 South Carolina Building Codes; the 2024 editions take effect for local jurisdictions on January 1, 20271213. Berkeley County charges a non-refundable $25 administrative fee for each permit requested, while the remaining building-permit fee varies with the permit type and construction value9.

Who issues Berkeley County building permits and inspections?

Berkeley County Building and Codes Enforcement is the county office for residential and commercial permits, plan review and inspections in unincorporated Berkeley County141. Berkeley County Planning and Zoning handles the separate land-use review under the county zoning ordinance153. A permit applicant must call for every required inspection and should ask the permit clerk for the project's inspection list; work must begin within six months after permit issuance unless an extension is obtained16. The application itself remains valid for 180 days after submission, and failure to pick up and pay for the permit during that period means a new application is needed17. Municipal properties follow the applicable city's permitting and zoning process rather than the county's unincorporated-area process3.

Does Berkeley County have zoning?

Berkeley County administers zoning in the unincorporated part of the county, but the parcel's zoning district still must be confirmed through the county zoning map or Planning and Zoning Department2. An incorporated municipality may administer its own rules, so a city address should be checked with that municipal office3. The available county material does not establish one countywide answer for minimum dwelling size, minimum lot size, setbacks, lot coverage or building height; ask Planning and Zoning for the standards attached to the specific parcel152. Berkeley County does allow an accessory structure built to residential standards to be occupied temporarily while the primary residence is under construction, but it must be vacated within 30 days after the primary home's certificate of occupancy18.

How do septic permits work in Berkeley County?

South Carolina's Department of Environmental Services, not Berkeley County, evaluates the site and issues the septic permit for Berkeley County land5. Apply through the SCDES ePermitting system; if the site is suitable, SCDES issues a permit to construct, while an unsuitable finding leads to a discussion of other options619. After installation, an SCDES inspector returns to inspect the system before issuing approval to operate7. For a home without public or community sewer, obtain the septic permit before the county building permit4. Final septic approval, or the applicable water and sewer tap receipts, must reach the county before it issues a certificate of occupancy2021. Only about 0.2% of Berkeley County's soil area avoids a very-limited rating for a conventional drain field, making early site evaluation especially valuable22.

Can you live in an RV or tiny home in Berkeley County?

We could not confirm a general Berkeley County rule allowing long-term RV occupancy or permanent tiny-home occupancy on private land. Because unincorporated parcels are subject to county zoning, ask Berkeley County Planning and Zoning about the parcel's use rules, dwelling standards and setbacks before buying or moving a unit onsite215. The county's confirmed temporary housing provision covers an accessory structure built to residential standards while a primary residence is being constructed, and that structure must be vacated within 30 days after the primary residence receives its certificate of occupancy18. Any onsite septic system still requires SCDES site approval, construction permitting and a post-installation inspection, so off-grid sanitation is not permit-free197.

Building a home in Berkeley County: the steps in order

  1. Confirm whether the parcel is unincorporated and ask Berkeley County Planning and Zoning to verify its zoning district and allowed use315.
  2. If public or community sewer is unavailable, apply through SCDES ePermitting and obtain the septic permit before requesting the county building permit64.
  3. Submit the residential construction application and all applicable utility documents; the county may require a septic permit, sewer-availability letter or paid tap receipt21.
  4. Pay the $25 administrative fee for each requested permit and collect the approved permit within the application's 180-day validity period917.
  5. Post the permit card onsite and call for every required inspection as construction progresses116.
  6. Provide final septic approval or water and sewer tap receipts before requesting the certificate of occupancy20.

What should you check before buying land in Berkeley County?

Check zoning, sanitation, flood exposure and access before treating a parcel as buildable. Berkeley County Planning and Zoning should confirm the district and parcel-specific dimensional rules for unincorporated land215. SCDES should evaluate any proposed septic area because only about 0.2% of county soils avoid a very-limited rating for a conventional drain field522. For construction in a FEMA flood zone or Santee Cooper dam-breach area, applicable elevation certificates go to the Flood Plains Manager before the certificate of occupancy, with submissions also required at earlier construction stages23. A private residential well requires a Notice of Intent and a $70 state fee before drilling10. For a driveway entering a state highway, SCDOT controls access within its right-of-way24.

Watch-outs

  • A Berkeley County permit application expires after 180 days if the permit is not picked up and paid for, so do not apply before the project is ready to proceed17.
  • The permit applicant must request required inspections, and construction must begin within six months of permit issuance unless an extension is obtained16.
  • Flood-zone and Santee Cooper dam-breach-area projects require applicable elevation certificates during the permit process and before occupancy23.

Water rights & wells in Berkeley County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from South Carolina’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

S.C. Code 49-5-70(A)(4) exempts a person withdrawing groundwater at a single-family residence for noncommercial use; no withdrawal permit for a household well anywhere in SC, including inside a Capacity Use Area.

Limit: single-family/household use exempt; permit only >=3 MG/month (~100,000 gpd)
