Do you need a building permit in Georgetown County, South Carolina?
Unincorporated Georgetown County requires completed building-permit applications for new residential and commercial construction, with supporting documents and applicable approvals due before issuance.1 One- and two-family dwellings use the 2021 International Residential Code with South Carolina modifications; commercial and multifamily structures use the 2021 International Building Code with state modifications.11 Construction inspections are required, but the inspection types depend on the project.15 A new Georgetown County residence cannot be occupied until its certificate of occupancy is issued after all necessary inspections pass; septic-connected waste plumbing also needs state approval on file.16 South Carolina’s farm-structure code exemption excludes homes and attached structures, requires a preconstruction affidavit, and preserves local building-permit authority and flood standards.17
Who issues building permits in Georgetown County, South Carolina, and how do you reach them?
The Georgetown County Building Department issues building permits for unincorporated-area projects.18 The office is at 129 Screven Street, Room 249, Georgetown, SC 29440; call 843-545-3116, and request inspections at 843-545-3261.19 Call Georgetown County Zoning at 843-545-3602 for zoning review of residential, commercial and mobile-home applications.20 Inside Andrews, the town administers building permits, with an exemption for qualifying owner-performed work that does not waive inspections; state septic approval still applies where sewer is unavailable.35 County building applications need plans, a site plan, water or sewer approval and applicable project-specific approvals.21 Published residential fees can include building-permit, plan-review, fire-impact, impact and construction-sign charges.22
Does Georgetown County have zoning?
Georgetown County regulates land use in unincorporated areas designated on its official zoning maps; county GIS depicts the official district boundaries.232 Inside Andrews, town zoning applies, while septic approval remains with the state where sewer is unavailable.45 Georgetown County publishes district documents and a land-use/zoning designations chart; use the parcel’s district to find its standards.248 Minimum lot area and setbacks vary by district and use.1325 The ordinary cited height limit is 35 feet from grade, with conditional industrial exceptions.26 Along Highway 701 from Black River north to the Horry County boundary, the front setback is 90 feet.27 The schedule also requires 30% pervious surface for applicable lots; ask Zoning which district entry governs your parcel.28 We could not confirm a minimum dwelling floor area; ask Georgetown County Zoning about the proposed home’s dimensions.20
How do septic permits work in Georgetown County?
The South Carolina Department of Environmental Services approves residential septic systems in Georgetown County where public or community sewer is unavailable; the county building permit depends on that approval.67 Apply through state ePermitting; the application fee is $150 and the Permit to Construct lasts 5 years, with renewal requiring a new application and fee.299 Before covering the system, the installer must schedule an inspection; if the state inspector does not arrive within 30 minutes of the scheduled time, a licensed installer may self-inspect using the approved form and submit final documentation.30 Only 0.4% of Georgetown County soils avoid a severe-limitation rating for conventional drain fields, so make septic feasibility a purchase contingency.31 Where public sewer is accessible, an onsite wastewater permit cannot be issued.32
Can you live in an RV or tiny home on your land in Georgetown County?
Georgetown County's Destination Park District allows short-term camper occupancy for leisure activities near natural attractions, but that rule does not authorize long-term RV living elsewhere.33 We could not confirm a complete rule for long-term RV living, temporary camping or tiny-home occupancy, so ask the Zoning Department at 843-545-3602 about the parcel and proposed use before placing a unit.20 County zoning also bars parking or storing a travel trailer without current license plates on residentially zoned property unless it is in a completely enclosed building; that rule covers storage, not whether you may live in an RV.34 Manufactured homes require a county mobile-home permit and zoning review, and eligibility varies by district.12 The mobile-home process runs from Building to Zoning, then to the Assessor for registration and a sticker, and back to Building for fees; water and sewer proof or a state septic permit is also required.35 A permanent tiny home still faces the county's zoning controls and residential building code, but we could not confirm a separate tiny-home category.211
Building a home in Georgetown County: the steps, in order
- Ask Zoning to confirm the use, district, lot area, setbacks, height and pervious-surface rule for the parcel.13272628
- Confirm water and sewer service; where public or community sewer is unavailable, obtain state septic approval.6
- Obtain the driveway encroachment permit from SCDOT or Public Works, as applicable.36
- Prepare the plans, site plan, completed application and any applicable flood, fire, stormwater or other project-specific approvals.21
- File the building-permit application and plan-review payment with the Georgetown County Building Department.122
- If using the owner-builder exemption, appear and sign personally, supervise the work, use licensed trades where required and record the required notice.10
- Request each applicable inspection and wait for the certificate of occupancy before moving in.1516
What to check before you buy land in Georgetown County
Check Georgetown County zoning and septic feasibility before buying: lot standards vary by district, and only 0.4% of county soils avoid severe limitations for conventional drain fields.1331 Flood-zone residential projects need an elevation certificate and recorded non-conversion agreement where applicable; the original elevation certificate must be approved before final inspection can be scheduled.3738 New-home applications identify a driveway encroachment permit from SCDOT or Public Works.36 A private residential well requires a state Notice of Intent and $70 fee before construction.14 Composting or incinerating toilets are a conditional state permitting option for unsuitable sites, requiring engineered plans and approval to operate; pressurized-water graywater needs separate wastewater approval.3940
Watch-outs
- South Carolina adopted a newer set of 2024 building codes on August 26, 2025, but local jurisdictions including Georgetown County don't have to implement them until January 1, 2027, so expect a code change if you build after that date.41
- Georgetown County mobile-home applications require proof of water and sewer approval or a state septic permit; manufactured homes also face district eligibility rules.4212
- Do not occupy a new residence before its certificate of occupancy; all necessary inspections must pass, and septic-connected waste plumbing needs state approval on file.16
- South Carolina’s owner-builder exemption does not waive Georgetown County building permits, codes or zoning; personal supervision and a recorded notice are required, and sale or rent within 2 years creates a statutory presumption against the exemption.10
