1. South Carolina Retail License

   Every person who engages in business in South Carolina as a retailer must obtain a Retail License from the SC Department of Revenue before making any retail sales subject to sales and use tax, including internet sales and infrequent sales. A separate license is required for each business location. The license does not have to be renewed while the same taxpayer keeps operating at the same location, but a new application is required after a change of ownership or after 24 months with no sales.

2. General Liability Insurance for a South Carolina Pressure Washing Business

   South Carolina does not require a pressure washing business to carry general liability insurance as a condition of any state licence. It is a commercial requirement rather than a regulatory one: most property managers, HOAs and commercial clients require a certificate of insurance, commonly $1 million per occurrence, before hiring. If you use a company vehicle, commercial auto coverage is separate from general liability. Workers’ compensation is a genuine legal requirement once you regularly employ four or more people (S.C. Code Section 42-1-360). Insurers and producers are regulated by the SC Department of Insurance.

2. Columbia Stormwater / Wastewater Discharge Compliance

   Pressure washing wastewater carrying detergents, oils, sediment or other pollutants may not be discharged to storm drains, gutters or waterways. Stormwater in South Carolina is regulated by the SC Department of Environmental Services under the federal NPDES programme, and illicit-discharge enforcement in Columbia runs through the City of Columbia and Richland County stormwater programmes as MS4 permittees — not through a county environmental health office. Contain the wash water with a berm or mat, recover it with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer connection or an approved facility.

   No permit fee — this is an ongoing discharge-prohibition obligation, not a permit you apply for. Enforcement penalties apply for illicit discharge. The only priced item is your own containment and recovery equipment.·No application step and no waiting period; the obligation applies from your first job. Confirm approved disposal points with the City of Columbia stormwater programme before you start work.

3. Trade Name (DBA) — no state registration in South Carolina

   South Carolina has no DBA or fictitious-name filing at the state level: SC Business One Stop states that 'the state of South Carolina does not register DBAs,' and directs businesses to their municipality or county to learn how a DBA is documented there. In practice, record the trade name on your City of Columbia business license application, list it on your SC Department of Revenue business tax application, and list it as your trade name on the IRS EIN application. Check the Secretary of State's business name search first to be sure the name is not already in use.

   No filing fee — a trade name is recorded on your business license application rather than registered separately with the state or Richland County.·No separate filing step or waiting period; the trade name is recorded when you apply for or update your city business license.
