County business license guide
Last updated: October 5, 2026 • Next review: January 3, 2027
This guide explains the Charleston County, South Carolina business license layer in plain English. The most important question is not simply whether your mailing address says “Charleston.” It is which local government has jurisdiction over the exact business address.
A business inside the City of Charleston follows a different local path from a business in unincorporated Charleston County. Other cities and towns also have their own rules or licensing arrangements. Start with the address, then build the rest of the license, zoning, tax, and permit checklist around the correct jurisdiction.
Bottom line
Charleston County has an official Business License Application. The current county application covers unincorporated Charleston County plus the City of Folly Beach and the towns of James Island, Awendaw, Lincolnville, McClellanville, and Rockville.
That does not make the county application the universal route for every address in Charleston County. The City of Charleston, City of North Charleston, Town of Mount Pleasant, and other municipalities can have separate business-license, zoning, occupancy, building, fire, sign, hospitality-tax, or activity-permit rules.
Your safest first step is to identify the jurisdiction for the exact street address. If the parcel is in unincorporated Charleston County, start with county Revenue Collections and county Zoning & Planning. If the parcel is inside a municipality, start with that municipality even if “Charleston” appears in the mailing address.
Charleston County business changes: May 1–October 2, 2026
These material changes took effect during this guide’s review period.
- Updated business-license class schedule effective May 1, 2026. Ordinance 2373 updated the standardized class schedule for the license year beginning May 1, 2026. Use the county’s current ordinance rather than an older class schedule.
- Construction-permit consolidation effective July 1, 2026. Several sub-trade permits were removed and folded into the Main Building Permit, including masonry, carpentry/framing and fiber-cement siding, stucco, garage doors, and roof permits. Related fees also changed.
- Accessibility standard changed September 18, 2026. Charleston County lists ANSI A117.1-2026 as the accessibility standard effective September 18, 2026. This matters when a project is subject to county building review.
Coming soon: January 1, 2027 building-code change
Charleston County says projects submitted on or after January 1, 2027 will move to the 2024 International Building, Residential, Fire, Plumbing, Mechanical, and Fuel Gas Codes and the 2023 National Electrical Code, with applicable modifications. Projects crossing into January should check the applicable code edition.
First, check whether your address is in a city or unincorporated county area
Do not rely on the mailing city alone. A Charleston mailing address can be inside the City of Charleston, inside another municipality, or in unincorporated Charleston County. The local licensing and zoning route changes with that boundary.
Charleston County Zoning & Planning states that it administers the county Zoning and Land Development Regulations Ordinance for unincorporated portions of the county. The county also publishes a jurisdiction-and-zoning guide that directs users to the county GIS. If the parcel shows a jurisdiction other than Charleston County, the county instructions say to contact that municipality.
Practical address check
- Search the exact property address in the Charleston County GIS and note the jurisdiction shown for the parcel.
- If the jurisdiction is Charleston County, use the county business-license and unincorporated zoning paths in this guide.
- If a city or town is listed, use that municipality’s business-license and zoning process.
- If you perform work in several municipalities, check whether each jurisdiction requires its own local license for work performed there.
- Do this before signing a lease or paying for a build-out when zoning or occupancy approval could affect the site.
If your location is inside the City of Charleston, BLG has a separate Charleston, SC business license guide for the city layer.
What Charleston County, SC may handle
The main county office for the local business-license layer is Charleston County Revenue Collections. It administers county business licenses and collections for several municipalities, plus certain accommodations and hospitality collections.
| Issue | Unincorporated Charleston County | Inside a municipality |
|---|---|---|
| Basic local business license | Use the Charleston County business-license path. | Use the municipality’s route unless the county is specifically acting as that municipality’s licensing administrator. |
| Zoning | Charleston County Zoning & Planning administers the ZLDR. | The city or town generally controls its own zoning. Confirm the exact jurisdiction. |
| Building / occupancy | County Building Inspection Services may control when the site is in county building jurisdiction. | Use the municipality or other authority that has building jurisdiction for the address. |
| Food safety | South Carolina Department of Agriculture handles the state Retail Food Establishment permit program for restaurants, food trucks, and many other direct-to-consumer food businesses. Local zoning and business licensing still remain separate. | |
County business-license application and renewal
The county’s current online application lists these jurisdictions: Unincorporated Charleston County, Folly Beach, James Island, Awendaw, Lincolnville, McClellanville, and Rockville. Select the correct jurisdiction on the application rather than assuming the county option applies to every address.
Revenue Collections says renewals are due by April 30 each year and provides online renewal service. Use the current Charleston County business-license ordinance and class schedule for classification and rate rules.
What cities or towns may handle
Many Charleston County businesses are inside incorporated municipalities. That can move the basic business-license, zoning, occupancy, sign, and other local-permit questions away from the county path.
| Location | Current practical route |
|---|---|
| City of Charleston | The city requires a business license for businesses operating or generating income in city limits. A physical commercial location also uses a separate Certificate of Occupancy process. Start with the City of Charleston Business License Information page. |
| City of North Charleston | North Charleston uses its own current Customer Portal for the business-license application route. The former application page now tells users that the application has moved. |
| Town of Mount Pleasant | The Mount Pleasant Business License Division administers the town business license. The town says license fees are due before operations begin and annually on April 30. |
| Folly Beach, James Island, Awendaw, Lincolnville, McClellanville, Rockville | The current Charleston County application lists these municipalities as available business-license jurisdictions. Local zoning and other approvals can still differ by municipality. |
City vs county warning
Do not treat the county office as a substitute for a city zoning or occupancy check. For example, a business may use a county-administered revenue process but still be subject to municipal land-use rules. Likewise, a city business license does not replace state tax accounts, professional licensing, food permits, or alcohol licensing.
State-level registrations to check
South Carolina does not issue one universal statewide general business license. State filings instead depend on structure, taxes, employees, profession, and regulated activity. See BLG’s South Carolina business license guide for the broader state layer.
South Carolina Secretary of State
Corporations, LLCs, limited partnerships, and other filing entities generally use South Carolina Business Entities Online. Sole proprietorships and general partnerships do not file formation documents there simply because they start operating.
South Carolina Department of Revenue
If you make taxable retail sales or need another state business tax account, use the SCDOR Business Tax Application through MyDORWAY. A South Carolina Retail License is a state tax license. It is not the same as a Charleston County or city business license.
If you hire employees
South Carolina’s employer path can include SCDOR withholding, unemployment registration through SUITS, and new-hire reporting. South Carolina Business One Stop says employers must report new hires within 20 days after the first day of work. Its Hiring Employees page gathers the main state routes.
Professional and occupational licensing
A local business license does not authorize regulated professional work. Check South Carolina LLR for contractor licensing, cosmetology, accountancy, engineering, and other regulated occupations.
Federal EIN
If your business needs an Employer Identification Number, use the IRS EIN application. An EIN identifies the business for federal tax purposes; it is not permission to operate at a Charleston County address.
DBA, fictitious name, assumed name, and trade name layer
A DBA is a name issue, not an operating license. The South Carolina Secretary of State business-entity FAQ says the Secretary of State does not register DBA or trade names.
That means you should not send every Charleston County business owner to the county clerk for a generic “DBA license,” and you should not describe a trade name as permission to operate. The correct naming step depends on the legal entity, the name being used, and any specific filing or notice rule that applies to that situation.
If your entity is formed with the Secretary of State, first check the entity’s official name and any state filing that applies to the entity. Separately verify whether a local license application wants a DBA name listed. The Charleston County business-license form, for example, includes a DBA field, but entering a DBA on that form is not the same thing as obtaining a separate statewide DBA registration.
Zoning, home occupation, building, food, and industry permits
A basic business license does not answer whether the activity is allowed at the property. For a storefront, office, home business, restaurant, food truck, short-term rental, contractor, salon, or other regulated activity, there may be a second approval path.
County zoning and site use
For unincorporated property, use Charleston County Zoning & Planning and its documents and forms page. Check the permitted use before committing to a lease, renovation, sign, outdoor activity, or storage plan. If the GIS shows a municipality, use that municipality’s zoning process instead.
Home-based businesses
Unincorporated Charleston County has a specific home-occupation framework. The current county materials require a zoning permit for a home occupation and regulate issues such as who operates the business, customer activity, employees, vehicles, signs, storage, and the type of work conducted at the home. Do not assume that an online, consulting, cleaning, repair, beauty, food, or service business is exempt from zoning merely because customers rarely visit.
Some home activities follow separate rules. Cottage food, child care, short-term rental, personal services, and trade or repair activities can have different state or local requirements. Use the actual activity and address when asking the zoning office.
Building, change of use, and safety review
For a site under county building jurisdiction, a new business moving into an existing space can trigger safety review even when no construction is planned. A change of occupancy can require drawings and full permitting. Start with Building Inspection Services before assuming “no remodeling” means “no permit review.”
Remember the July 1, 2026 permit consolidation noted above. Contractors and property owners should use the county’s current Main Building Permit structure rather than an old sub-trade permit list.
Signs and exterior changes
A business license does not automatically approve a wall sign, monument sign, temporary sign, awning, exterior alteration, or site change. Check the zoning and building authority for the exact parcel before ordering a sign.
Short-term rentals
For unincorporated Charleston County, the ZLDR separates Limited Home Rental, Extended Home Rental, and Commercial Guest House. Current rules require short-term-rental zoning approval and a business license, with annual renewals. Use the county’s current short-term-rental packets.
Charleston County also has a Local Accommodations Tax application that applies to newly operating short-term rentals and identifies county and municipal accommodations-fee jurisdictions. Zoning and business-license rules remain separate from the accommodations-tax account.
Temporary events and temporary sales
County zoning materials include separate paths for special events and temporary sales. If you are a host or vendor, verify the event approval, business-license jurisdiction, and any food or alcohol permit before the event date.
Contractors and construction trades
Contractors should check both the local business-license jurisdiction and any required state contractor license through LLR. Permit responsibility is separate from the business license, and the July 2026 county permit consolidation changed the permit structure for several sub-trades.
Restaurants, caterers, food trucks, and temporary food
SCDA Retail Food Safety handles state permitting for restaurants, caterers, many retail food operations, and mobile food establishments. SCDA says a Retail Food Establishment Permit must be obtained before covered direct-to-consumer retail food sales begin.
Mobile units can require a permitted commissary and mobile-unit paperwork. Temporary food events have a separate state path. Qualifying home-based food production is different: SCDA says it does not issue a food permit or license to qualifying operators under the Home-Based Food Production Law. Local zoning and business licensing can still apply.
Food businesses: change coming October 28, 2026
SCDA says a new South Carolina shrimp-disclaimer law takes effect October 28, 2026 for retail food establishments selling ready-to-eat prepared or cooked shrimp. Restaurants, mobile food units, cafeterias, and seafood retailers that cook shrimp should review the state guidance before that date.
Alcohol and other regulated activities
Alcohol sales use a separate state path through SCDOR Alcohol Beverage Licensing. A county or city business license is not an alcohol license. Contractors, cosmetology businesses, and other regulated professions should also check the appropriate LLR board.
Step-by-step checklist for a Charleston County business
- Identify the jurisdiction. Use the exact street address and county GIS. Do not use the mailing city as your only test.
- Check local zoning before spending money. Confirm that your use is allowed, especially for a home business, storefront, food operation, contractor yard, rental, or activity with customers or storage.
- Use the correct local business-license route. Use Charleston County for unincorporated county and the municipalities listed on the county application; use the correct municipal process elsewhere.
- Check occupancy and building review. A new tenant or change of use can trigger review even without major construction.
- Form the entity if needed. Use the South Carolina Secretary of State for LLCs, corporations, and other filing entities.
- Open the correct state tax accounts. Use the SCDOR Business Tax Application for Retail License, withholding, and other applicable tax accounts.
- Check regulated-industry permits. Food, alcohol, contracting, professional services, short-term rentals, and other activities can require separate approvals.
- If hiring, complete the employer layer. Check withholding, SUITS unemployment registration, new-hire reporting, and other employer duties.
- Save the approval records. Keep the current license, zoning approval, permits, state account confirmations, and renewal dates together.
Common mistakes in Charleston County
- Using the mailing city as the jurisdiction. Postal addresses and municipal boundaries are not the same thing.
- Assuming one county license covers every municipality. The county application lists specific jurisdictions; other cities use separate routes.
- Confusing administration with jurisdiction. Charleston County can collect a municipal license or hospitality tax while the municipality still controls zoning.
- Signing a lease before checking use and occupancy. A permitted business activity at one address may not be allowed at another.
- Using an old permit list. County construction sub-trade permits changed July 1, 2026.
- Treating an LLC, DBA, EIN, Retail License, or professional license as the local business license. These are separate layers.
- Starting a food or alcohol activity after getting only the local license. State permits may still be required.
- Forgetting the employer layer. State withholding, unemployment registration, and new-hire reporting are separate tasks.
What to ask when you contact county or city offices
Have the exact address and a short description of what the business will actually do. “Consulting company” or “retail” may not be enough if customers, food, storage, vehicles, deliveries, outdoor work, or regulated services are involved.
“I plan to operate a [business type] at [exact address]. The business will be [home-based / storefront / office / mobile / online]. Customers [will / will not] visit the location, and I expect [employees / deliveries / storage / signs / vehicles]. Is this address in your jurisdiction? What business license, zoning approval, occupancy approval, and activity-specific permits should I complete before I begin operating?”
Questions to ask before paying
- Is this address inside your city or town, or in unincorporated Charleston County?
- Is the proposed use allowed at this exact parcel?
- Do I need zoning approval before the business license can be issued?
- Does this location require a Certificate of Occupancy, safety review, or change-of-use permit?
- Is there a separate sign, home-occupation, short-term-rental, food, alcohol, or professional-license step?
- Which current online application or portal should I use?
- If I work in other municipalities, do I need separate local licenses there?
