Do you need a building permit in Georgetown County, South Carolina?
Yes. Unincorporated Georgetown County requires residential building permits and applies the 2021 International Residential Code with South Carolina modifications to one- and two-family dwellings; the 2021 International Building Code governs commercial, multifamily and other structures.1 The Building Department provides pre-construction plan review, permit applications, project checklists, inspection forms and a dedicated inspection-request line.10 South Carolina's newer 2024 codes have been adopted, but local implementation is scheduled for January 1, 2027, so confirm the applicable edition if construction will cross that changeover.11 Building fees are locally administered, and the available facts do not establish a single county fee for every project; ask the Building Department for the current calculation before budgeting.12
Who is the Georgetown County building department, and how do you reach them?
The Georgetown County Building Department is the permit and inspection office for work in the county's unincorporated area.1 It is at 129 Screven Street, Room 249, Georgetown, South Carolina; call 843-545-3116, and request inspections at 843-545-3261.13 The department publishes pre-construction plan-review materials, building-permit applications, checklists, inspection forms and mobile-home forms.10 Zoning reviews residential, commercial and mobile-home permits, so call the Georgetown County Zoning Department at 843-545-3602 to establish the district and site standards before submitting construction plans.14 For a site without public or community sewer, obtain SC DES septic approval first because the county cannot issue the building permit without it.6
Does Georgetown County have zoning?
Georgetown County has zoning, and the Zoning Department reviews residential, commercial and mobile-home permits.214 Lot size, setbacks and height depend on the parcel's zoning district and proposed use: published examples range from a one-acre minimum in FA and R-1 AC to 10,000 square feet in R-10 and 6,000 square feet in R-6.8 The ordinary height limit shown in the district schedule is generally 35 feet, with district-specific exceptions.15 Setbacks also vary by district, while structures along US Highway 17 generally face a 90-foot setback from the right-of-way; in Murrells Inlet that special rule applies only to the US Highway 17 Bypass.16 The available rules do not confirm a countywide minimum dwelling size, so ask Zoning about the exact parcel rather than treating minimum lot area as minimum house size.
How do septic permits work in Georgetown County?
SC DES, not Georgetown County, approves and permits septic systems for homes and manufactured homes on property without public or community sewer.3 Apply through the SC DES ePermitting portal; the application fee is $150, the traditional process includes a site visit, and a Permit to Construct remains valid for five years.6 Before the system is covered, the installer must schedule an SC DES inspection; if the inspector has not arrived within 30 minutes of the scheduled time, a licensed installer may use the approved self-inspection process.17 Only 0.4% of Georgetown County soils avoid a severe-limitation rating for a conventional drain field, so make septic feasibility an early purchase contingency rather than assuming a conventional system will work.18 Where public sewer is accessible, state rules bar an onsite wastewater permit, so establish sewer availability before designing the site.19
Can you live in an RV or tiny home on your land in Georgetown County?
We could not confirm a complete Georgetown County rule for living long-term in an RV, temporary camping on private land or tiny-home occupancy, so ask the Zoning Department at 843-545-3602 before buying or placing a unit.14 Manufactured homes have a clearer path: they are allowed on individual lots in residential districts except RR, R-6, R-8, R-10, GRR, Neighborhood Amenity and Medical districts, subject to the county's stated conditions and district rules.7 A public or private utility may not start water, electricity or gas service to a mobile home until the owner or lessee presents a valid mobile-home permit signed by the Building Inspector.20 A manufactured home using septic also needs SC DES approval before the county can issue its permit.3
Building a home in Georgetown County: the steps, in order
- Ask Zoning to confirm the parcel's district, allowed use, minimum lot area, setbacks and height limit.81615
- Submit a safe ingress-and-egress plan to the Zoning Administrator, and coordinate separately with SCDOT if the driveway enters a state highway.2122
- Establish sewer availability; if no public or community sewer serves the site, obtain the SC DES septic permit before seeking the county building permit.6
- For a private residential well, submit a Notice of Intent and the $70 fee before construction; the well driller must also notify SC DES 48 hours before installation.9
- Use the county's pre-construction review and checklist, then file with the Building Department after zoning and septic or sewer questions are resolved.10
- If using the owner-builder exemption, personally sign and supervise the work, use licensed trades where required and record the statutory notice.4
- Request required inspections at 843-545-3261 as construction proceeds.13
What to check before you buy land in Georgetown County
Start with a zoning verification and septic contingency: lot dimensions that work in one district may fail another district's minimum area or setbacks, and only 0.4% of county soils avoid a severe-limitation rating for a conventional drain field.81618 Check flood status before fixing a house site because any structure proposed in a flood-prone area must comply with the Georgetown County Flood Damage Prevention Ordinance.23 Confirm legal and safe access as well; Georgetown County requires the Zoning Administrator to receive an adequate ingress-and-egress plan for land uses.21 If the parcel needs a private well, account for the SC DES notice, fee and advance installation notice.9 Finally, verify that any subdivision plat received the required planning approval before relying on it for a permit.24
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.11
- A mobile home's utilities cannot be connected until the owner or lessee presents a valid mobile-home permit signed by the Building Inspector.20
- South Carolina's owner-builder exemption requires personal supervision and a recorded public notice; selling or renting within two years creates a legal presumption against the exemption.4
