Building permits, zoning and land rules 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 ordinance¹⁴. The current mandatory statewide editions are the 2021 South Carolina Building Codes; the 2024 editions take effect for local jurisdictions on January 1, 2027^15,16. 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 value¹. Owners who build their own one- or two-family home must personally supervise the work, file the disclosure statement with the Register of Deeds, and not sell or rent the home within 2 years, since a sale or rental in that window is presumed to violate the exemption⁹.

Berkeley County Building and Codes Enforcement is the county office for residential and commercial permits, plan review and inspections in unincorporated Berkeley County^1,14. Berkeley County Planning and Zoning handles the separate land-use review under the county zoning ordinance^3,5. 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 obtained¹. Municipal properties follow the applicable city's permitting and zoning process rather than the county's unincorporated-area process³.

Berkeley County administers zoning in the unincorporated part of the county; use the Official Zoning Map to identify the parcel's district, then consult the county's district cheat sheet and current ordinance^2,5. Setbacks vary by district and parcel size, while accessory structures generally belong in rear or side yards with at least a 5-foot setback unless a district rule says otherwise⁶. The dimensional guide shows a maximum 65% coverage in many residential and commercial classifications, but the amended zoning ordinance controls and district provisions may differ⁶. Minimum lot size depends on the district and on utilities: R-1 needs 30,000 square feet with a well and septic system or 14,000 square feet with public water or sewer, R-1R and R-2R need 2 acres, and R-15 needs 15 acres¹⁷. Maximum height is under 40 feet in R-1 (to the highest part of the structure) and in R-15 (to the eave)¹⁷. Manufactured homes are a permitted or conditional use in some districts such as R-2, but the Rural Single-Family Residential (R1-R) district described in the Cordesville Community zoning matter lists manufactured homes as a prohibited housing type^12,13. We could not confirm a minimum dwelling size for unincorporated Berkeley County; ask Planning and Zoning about the specific parcel⁵. An incorporated municipality may administer its own zoning rules³.

South Carolina's Department of Environmental Services, not Berkeley County, evaluates the site and issues the septic permit for Berkeley County land⁷. 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 options^7,18. After installation, an SCDES inspector returns to inspect the system before issuing approval to operate⁸. 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 occupancy¹⁹. 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 valuable²⁰.

In unincorporated Berkeley County, an RV or travel trailer cannot be used as an intermittent, temporary or permanent residence while parked or stored on a residential lot¹⁰. The owner or tenant may store a travel trailer they own on a residential lot, but parking one on a vacant lot is prohibited unless the lot is adjacent to the owner's primary residence¹⁰. The county has a separate temporary-use-permit process with limited exceptions for temporary RV housing; ask Planning and Zoning whether it fits your situation^5,10. We could not confirm a general county rule allowing 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 onsite^2,5. 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 occupancy²¹. Any onsite septic system still requires SCDES site approval, construction permitting and a post-installation inspection, so off-grid sanitation is not permit-free^8,18.

1. Confirm whether the parcel is unincorporated, identify its district on the Official Zoning Map, and ask Berkeley County Planning and Zoning to verify the allowed use^3,5.
2. Confirm the district's setbacks and lot-coverage standard before placing the house or accessory buildings⁶.
3. If public or community sewer is unavailable, apply through SCDES ePermitting and obtain the septic permit before requesting the county building permit^4,7.
4. Submit the residential construction application with the applicable septic permit, sewer-availability letter or paid tap receipt¹⁹.
5. Pay the $25 administrative fee for each requested permit, post the permit card onsite and call for every required inspection as construction progresses¹.
6. Provide final septic approval or water and sewer tap receipts before requesting the certificate of occupancy¹⁹.

Check zoning, sanitation, flood exposure and access before treating a parcel as buildable. For unincorporated land, identify the district on the Official Zoning Map and have Berkeley County Planning and Zoning confirm the allowed use, setbacks and coverage limit^5,6. SCDES should evaluate any proposed septic area because only about 0.2% of county soils avoid a very-limited rating for a conventional drain field^7,20. Construction in a FEMA flood zone or Santee Cooper dam-breach area requires applicable elevation certificates during permitting and before occupancy¹. A private residential well requires a Notice of Intent and a $70 state fee before drilling¹¹. SCDOT controls driveway access within a state-highway right-of-way²².
