Dillon County, SC: Owner-Builder Allowed

Dillon County, South Carolina issues building permits for construction and remodeling and follows up with inspections, but its published page does not say that every project requires one¹. The county requires zoning permits for land uses in unincorporated Dillon County, while incorporated towns may apply their own building and zoning rules^1,2. Where public or community sewer is unavailable, septic permits come from the state environmental agency (SCDES), not the county or any town, and must precede the county building permit³.

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

Dillon County Building Code Enforcement issues permits for construction and remodeling, including electrical, plumbing and mechanical work, and provides follow-up inspections.

Dillon County Building Code Enforcement issues permits for construction and remodeling, including electrical, plumbing and mechanical work, and provides follow-up inspections¹. The county page does not say that every project requires a permit, so confirm the proposed work with the department before starting¹. South Carolina exempts specified minor residential improvements from permit applications, including a one-story detached accessory structure no larger than 200 square feet and a fence no higher than 7 feet⁴. County staff review plans for code compliance and inspect residential, commercial, industrial and manufactured-home setup work during and after construction². The current statewide code baseline is the 2021 South Carolina Building Codes, effective January 1, 2023⁷.

Who is the Dillon County building department, and how do you reach it?

Dillon County combines Building Code Enforcement with Planning & Zoning at 401 W. Main St., Suite 201, Dillon, SC 29536; call (843)841-3874 or email dilloncode17@dilloncountysc.org.

Dillon County combines Building Code Enforcement with Planning & Zoning at 401 W. Main St., Suite 201, Dillon, SC 29536; call (843)841-3874 or email dilloncode17@dilloncountysc.org¹. The office issues building permits, conducts follow-up inspections, issues zoning permits and interprets the zoning ordinance¹. We could not confirm Dillon County's current building-permit fees, submission location or review timeline; ask the office what the proposed project requires and costs¹. A qualifying owner-builder must personally appear and sign the application, supervise construction, use properly licensed or registered workers where required, and promptly record notice with the register of deeds⁴. The licensing exemption does not remove county permit, code or zoning requirements⁴.

Does Dillon County have zoning?

Yes.

Yes. Dillon County Planning & Zoning enforces the County Zoning Ordinance and issues zoning permits for land uses in unincorporated Dillon County². The county's GIS zoning map can identify a parcel's category, but some proposed uses require rezoning and others may require a special exception, variance or conditional-use review². Incorporated municipalities may apply separate rules, so first confirm whether the parcel is under county jurisdiction¹. We could not confirm the county's minimum home size, minimum lot size, setbacks, lot coverage or building-height schedule. Ask Planning & Zoning for the parcel's district, allowed use and dimensional standards before choosing a house site. The online GIS may lag County Council action and is not exact for official purposes, so request current confirmation from county staff².

How do septic permits work in Dillon County?

SCDES, not Dillon County, handles onsite-wastewater approval, permitting and inspection in Dillon County.

SCDES, not Dillon County, handles onsite-wastewater approval, permitting and inspection in Dillon County³. For a home or manufactured home on land without public or community sewer, submit the Onsite Wastewater System Application online with the property plat or deed and the $150 fee³. Under the traditional process, SCDES visits the site and issues a Permit to Construct if it approves the site; the permit is valid for 5 years³. SCDES approval must come before the county building permit³. A licensed installer must schedule the SCDES inspection before covering the system⁸. Only about 2.1% of Dillon County soils rate without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency⁶.

Can you live in an RV or tiny home on your land in Dillon County?

We could not confirm a Dillon County rule that broadly allows or prohibits long-term RV living on private land.

We could not confirm a Dillon County rule that broadly allows or prohibits long-term RV living on private land. We also could not confirm how the county classifies tiny homes or whether it sets a minimum dwelling size. Unincorporated Dillon County requires zoning permits for land uses, and the answer may depend on the parcel's zoning category and the proposed use². Before buying an RV or tiny home for a site, ask Planning & Zoning for a written parcel-specific answer covering occupancy, utility connections, setbacks and temporary use during construction. A manufactured home is not automatically a proxy for a tiny home: Dillon County separately inspects manufactured-home setup during and after construction¹. For manufactured homes, a unit counts as a Dillon County residential designed manufactured home only if it has at least 900 square feet of enclosed living area, among other design requirements; that figure is part of the definition, not a minimum size for every dwelling⁹.

How do you build a home in Dillon County?

Ask Dillon County Planning & Zoning to confirm county jurisdiction, the parcel's zoning category, allowed residential use and dimensional standards.

Ask Dillon County Planning & Zoning to confirm county jurisdiction, the parcel's zoning category, allowed residential use and dimensional standards².
Determine whether public or community sewer serves the parcel; if not, apply online to SCDES with the onsite-wastewater application, plat or deed, and $150 fee³.
If drilling an individual residential well, submit the SCDES Notice of Intent before construction and budget the $70 fee⁵.
Ask Dillon County Building Code Enforcement which plans and applications the project requires, because the published county process is incomplete¹.
If claiming the owner-builder exemption, appear personally to sign, supervise the work, use licensed trades where required and record the required notice⁴.
Arrange county building inspections and have the licensed septic installer schedule the SCDES inspection before the system is covered^1,8.
Obtain a certificate of occupancy before occupying a new building covered by South Carolina's Energy Standard¹⁰.

What should you check before buying land in Dillon County?

Start with jurisdiction and zoning: verify that the parcel is in unincorporated Dillon County, then obtain its current zoning category and allowed uses from Planning & Zoning because the online map may lag official action². Check sewer before septic because SCDES cannot permit onsite wastewater where public sewer is accessible¹¹. Only about 2.1% of county soils rate without severe limitations for a conventional drain field, so do not close before resolving septic feasibility⁶. For an individual residential well, SCDES requires a Notice of Intent before construction⁵. Determine whether road frontage is county or state maintained; a qualifying residential entrance on a state-highway right-of-way falls under SCDOT's driveway program¹². We could not confirm Dillon County's floodplain-development process, so ask Planning & Zoning who reviews the site. The effective property-tax rate is about 0.5%, and the median annual bill is about $425⁶.

Watch-outs

Only about 2.1% of Dillon County soils rate without severe limitations for a conventional septic drain field, so do not assume an undeveloped parcel will support a conventional system⁶.
The county's online GIS may lag zoning changes and is not exact for official purposes; request current parcel information from Planning & Zoning².
We could not confirm Dillon County rules for RV occupancy, tiny homes, minimum dwelling size, setbacks or floodplain development; ask Planning & Zoning at (843)841-3874 before committing to a design or use¹.

South Carolina rules that apply here

Owner-builder exemptionAvailable (with conditions)
An owner of residential property who improves the property or builds or improves structures or appurtenances for the owner's personal or family occupancy, including qualifying one-family or two-family residences, in Dillon County and elsewhere in South Carolina.
- The owner must do the work personally, with the owner's employees, or with licensed contractors or registered entities or individuals.
- The structure, structures, or appurtenances must be intended for the owner's sole occupancy or occupancy by the owner's family and not intended for sale or rent.

Agricultural exemptionConditional
Exemption from the federal Produce Safety Rule administered through the South Carolina Department of Agriculture for qualifying growers.
- The grower must meet an exemption category and submit an application to SCDA.
- The application requires information about the operation and certification of compliance; SCDA then issues a certificate of exemption.

- Local regulations must require that land-development plans, including subdivision plats, are not approved unless building sites can be used safely without danger from flood, inundation, or other threats to health, safety, or public welfare.
- Local regulations may require streets, water, sewers, septic tanks, and other utilities or facilities as conditions precedent to plan approval.
- After local land-development regulations are adopted, no subdivision plat or land-development plan may be filed or recorded, and no building permit may be issued, until the plan or plat bears the required approval stamp and signature.

Driveway accessLimited
Residential driveway entrances within the right-of-way of South Carolina state highways.
- The driveway must provide ingress and egress to abutting property.
- Access must not constitute hazardous conditions.
- The property must be an existing developed residential property or property being developed for the owner's personal use.
- Commercial, speculative, and resale purposes are excluded.
- A standard driveway has a maximum paved throat width of 16 feet and may include up to a 30-inch diameter pipe where required for drainage.

Building in a floodplainLimited
Land-disturbing development in South Carolina, including development in flood-prone areas where the activity changes natural cover or topography and may alter stormwater runoff.
- Before a nonexempt land-disturbing activity proceeds, the responsible person must submit a stormwater-management and sediment-control plan to the appropriate implementing agency and obtain a permit.
- The statute exempts agricultural production activities, subject to its stated exception for certain agricultural structures of one or more acres requiring a building permit; forestry; mining activities regulated under Title 48, Chapter 20; separately built single-family residences or accessory buildings not part of multiple construction in a subdivision; certain activities already subject to conditioned state or federal environmental authorization; specified utility activities; railroad maintenance or rebuilding; certain state-land activities; and local-government or special-purpose/public-service-district repair and maintenance.
- Under Regulation 72-302, an implementing agency may grant a stormwater-management waiver upon written request; a quantitative-and-qualitative waiver may be available if the project returns the disturbed area to pre-development runoff condition and the pre-development land use is unchanged, and a water-quantity waiver or variance may be available under the regulation's stated demonstrations.
- The State may delegate plan review, approval, inspection, enforcement, education, and training to local governments or conservation districts. The SCDNR directs floodplain-development questions to the Local NFIP Administrator for the relevant community; local floodplain-development requirements therefore remain site- and community-specific.
- For activities disturbing two acres or less that are not part of a larger common plan of development or sale, Regulation 72-305 requires submission of a simplified plan but states that it does not require implementing-agency approval or preparation/certification by the specified designers.
simplified-plan threshold: <= 2 acres of actual land disturbance (Only where the activity is not part of a larger common plan of development or sale; the simplified plan does not require implementing-agency approval.)
“Unless exempted, no person may engage in a land disturbing activity without first submitting a stormwater management and sediment control plan”
