The Darlington County Codes Enforcement Department issues permits for every trade that applies, and states plainly the things it does not handle — septic, site plans, mobile home registration and rental inspections among them.
This Darlington County building permit guide covers the two sets of drawings and plan review fee, the E911 address inquiry that comes first, the owner-builder notice filed at the Clerk of Court, and the clear list of what Codes Enforcement does not handle.
Scope: unincorporated Darlington County. Darlington, Hartsville, Lamar and Society Hill may permit or zone their own — confirm from the parcel.
Two things happen before the permit counter. The E911 address inquiry is completed at the courthouse, and residential owner-builders must file notice with the Clerk of Court's office. Neither is part of the building application, and the permit will not issue without them.
What requires a permit in Darlington County?
The Darlington County Codes Enforcement Department, at 1 Public Square, Room 303, Darlington, SC 29532 (843-398-4011, Monday to Friday 8:30am to 5:00pm), handles building permits, plan reviews and mobile home inspections, alongside litter control, nuisance and animal control. Permits are issued for all that apply — building, electrical, plumbing, gas and mechanical — and the county runs online permitting through its EnerGov Self Service portal.
The department states what it does not do, and that saves calls: it does not do site plans, septic tanks or mobile home registration, and it does not inspect rental properties. Tenant complaints about living conditions go to the State Housing Authority (803-734-2000) rather than to the county.

South Carolina enforces the South Carolina Building Codes adopted by the Building Codes Council under S.C. Code Ann. § 6-9-50; the 2021 codes are in force, and the 2024 codes take effect for every county and municipality on 1 January 2027 (the energy code stays the 2009 IECC).

Darlington County building department: who handles permitting
The county’s checklist starts every permit with a deed plat approved by the Planning Department and the E911 address inquiry (both in Courthouse Room 405), plus the septic or sewer permit. Residential new construction, additions and garages or storage buildings then need two sets of drawings, a plan review fee, and a South Carolina licensed contractor or a documented exemption. All commercial new construction and additions need the same two sets of drawings and plan review fee; assembly, educational, institutional and hazardous occupancies of any size, and any other building of 5,000 square feet or three storeys, need drawings sealed by a South Carolina licensed architect and engineer.

On a new build on a previously unaddressed parcel, that inquiry is the first step rather than an afterthought — the address has to exist before the permit can reference it.
The county's permit application identifies the jurisdiction on the form, reflecting that Darlington County contains several municipalities including Darlington, Hartsville, Lamar and Society Hill. Hartsville operates its own zoning office. Confirm from the parcel which authority applies before assuming the county, particularly around Hartsville.

📞|Darlington publishes the state numbers you actually need. The county lists direct lines for the SC Building Codes Council, the Residential Builders Commission, the Contractor's Licensing Board, the Manufactured Housing Board and the State Fire Marshal. On a licensing or manufactured-housing question, those route faster than the county switchboard — and they are the right boards, which is not always obvious given South Carolina licenses through two separate ones.
In 2025, building permits issued in unincorporated Darlington County authorized 175 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Solar permits in Darlington County
Solar in Darlington County is filed as an electrical record alongside whatever else applies, and the submittal requires a South Carolina licensed contractor or a documented exemption — an undocumented assumption of exemption is not sufficient. Confirm which licences your installer actually holds before the application is filed: on commercial work a rooftop array can need the Miscellaneous Metals, Roofing or Building and Electrical subclassifications, while on homes the Residential Builders Commission registers solar installers and a residential electrician does the wiring.

A reroof in unincorporated Darlington County is issued as a building record by Codes Enforcement, with online permitting available through the department. Roofing is its own general contractor subclassification in South Carolina, and it absorbed the former General Roofing and Specialty Roofing classifications, so an older pocket card can read differently from the current licence record — check the LLR verification lookup rather than the card alone.
Solar and roofing work follow statewide licensing rules, and utilities run interconnection on their own timeline. Solar and roofing rules in South Carolina
Darlington County permit cost
Darlington County charges a permit fee and a separate plan review fee, with permits issued for all trades that apply — building, electrical, plumbing, gas and mechanical. Applications and fees are handled through Codes Enforcement, with online permitting available.
Two costs sit outside the department. Septic is not a county matter — the department states it does not do septic tanks, and onsite wastewater permitting is a state function with its own fee. Mobile home registration is likewise not handled here, though mobile home inspections are. Confirm current amounts before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | Per county fee schedule, by type and valuation |
| Plan review fee | Charged separately on residential and commercial |
| Trade permits | Building, electrical, plumbing, gas, mechanical as applicable |
| Septic | A state permit with its own fee, not handled by the county |
| Mobile home registration | Not handled by Codes Enforcement |
| Owner-builder | Clerk of Court filing required before issuance |

Darlington County trade permits
Building, electrical, plumbing, gas and mechanical permits are issued for all that apply. Four Darlington specifics:
Bring two sets of drawings
Residential new construction, additions and garages or storage buildings, and all commercial new construction and additions, each require two sets of drawings and a plan review fee.
Do the E911 address inquiry first
The address inquiry happens at the courthouse before the permit application. On a new build on an unaddressed parcel it is the first step, not a formality.
Owner-builder files at the Clerk of Court
For residential owner-builder work the owner must file notice with the Clerk of Court’s office in Courthouse Room B-4. Bring proof of that filing to the permit counter.
Licence or documented exemption
The submittal requires a South Carolina licensed contractor or a documented exemption. An undocumented assumption of exemption is not sufficient.
South Carolina licenses contractors through two boards in the Department of Labor, Licensing and Regulation: the Contractor’s Licensing Board (general and mechanical work over $10,000) and the Residential Builders Commission (residential builders over $5,000; residential electricians, plumbers, HVAC and other specialty work over $500).

Here is how to get a building permit in Darlington County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Darlington County contains several municipalities including Darlington, Hartsville, Lamar and Society Hill. Hartsville operates its own zoning office. Confirm from the parcel rather than the address.
The address inquiry at the courthouse comes before the permit application, particularly on a new build on a previously unaddressed parcel.
The department does not do septic tanks. Onsite wastewater permitting is handled by SCDES under Regulation 61-56, with its own application and timeline.
Residential and commercial new construction and additions each require two sets of drawings and a plan review fee, plus a South Carolina licensed contractor or a documented exemption.
Residential owner-builders must file notice with the Clerk of Court's office before the permit will issue.
Permits are issued for all that apply — building, electrical, plumbing, gas and mechanical. Keep the permit and approved plans on site through to final.
Inspections in Darlington County
Codes Enforcement handles building permits, plan reviews and mobile home inspections, with online permitting available through the department. Typical checkpoints follow the adopted code sequence through footing and foundation, trade rough-ins, framing, insulation and final.
Know the boundaries of what this department inspects. It does not inspect rental properties — tenant complaints about living conditions go to the State Housing Authority. It does not do site plans, septic tanks or mobile home registration, though it does inspect mobile homes.
Separately from building permits, encroachment and utility permits are issued through Roads and Bridges. On a job involving a driveway tie-in or a utility crossing in the county right of way, that is a different department with its own application, and it is worth opening early.
Keep the permit and approved plans on site throughout, and route septic, site plan and rental questions to the correct agency rather than to Codes Enforcement.

Who issues building permits in Darlington County, SC?
The Darlington County Codes Enforcement Department, 1 Public Square, Room 303, Darlington, SC 29532 (843-398-4011, Monday to Friday 8:30am to 5:00pm), which handles building permits, plan reviews and mobile home inspections. Online permitting is available through the county’s EnerGov Self Service portal.
What does Darlington County need for a residential permit?
For new construction, additions and garages or storage buildings: two sets of drawings, a plan review fee, and a South Carolina licensed contractor or a documented exemption.
What does a commercial application need?
All commercial new construction and additions require two sets of drawings and a plan review fee, on the same basis as residential.
What is the E911 address inquiry?
An address lookup completed at the courthouse before the permit application. On a new build on a previously unaddressed parcel, the address has to exist before the permit can reference it.
Can I act as my own builder?
For residential owner-builder work, the owner must file notice with the Clerk of Court's office before a permit will issue. State law limits the route to a home for the owner’s or family’s own use; a sale or rental within two years of completion is treated as evidence that it was built for sale or rent (S.C. Code Ann. § 40-59-260).
Does Darlington County handle septic?
No. The department states it does not do septic tanks. Onsite wastewater permitting is handled by the SC Department of Environmental Services under Regulation 61-56.
Does the county register mobile homes?
No. Codes Enforcement inspects mobile homes but does not handle mobile home registration.
Does the county inspect rental properties?
No. Tenant complaints about living conditions should be made to the State Housing Authority rather than to the county.
Which permits will I be issued?
Permits are issued for all that apply — building, electrical, plumbing, gas and mechanical — each as its own record.
Where do I get a driveway or utility permit?
Encroachment and utility permits are issued through the county's Roads and Bridges department, separately from building permits.
Does the county publish state licensing contacts?
Yes. Darlington publishes direct numbers for the SC Building Codes Council, Residential Builders Commission, Contractor's Licensing Board, Manufactured Housing Board and State Fire Marshal — useful because South Carolina licenses through two separate boards.
Which building code does Darlington County enforce?
The South Carolina Building Codes as adopted with state modifications by the SC Building Codes Council. The 2021 editions apply now, with the 2024 editions adopted in August 2025 and implementation set for 1 January 2027.
