  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.

    Official government source

    $50 per location, non-refundable, and it is a one-time fee rather than an annual charge.Not published by SC DOR. Applying through MyDORWAY is the fastest route — confirm current issuance time when you apply.

  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.

    Official government source

    No state fee and no published rate — premiums are set by the carrier from your payroll, revenue, equipment and claims history, and no South Carolina agency publishes premium figures. Get quotes from several licensed carriers; you can verify a carrier or producer is licensed through the SC Department of Insurance.Coverage is bound by your carrier, often the same day online; there is no state application or waiting period.

City of Charleston / Charleston County

3 stops
  1. City of Charleston Business License

    Every business operating or earning income within the City of Charleston must hold an annual Business License, issued by the Revenue Collections Division through the Permit Center. Pressure washing companies renew each year; the fee is based on gross income and the NAICS rate class rather than a flat amount.

    Official government source

    Set by the city's Business License Ordinance: the annual fee is calculated from the business's gross income (projected gross for a new business) and the NAICS-based rate class, so there is no flat amount. Licenses expire April 30 each year.Apply through the Permit Center's Customer Self Service portal; the city's stated goal is to respond to a new application within 2 business days, with a 10-business-day review turnaround.

  2. Charleston 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 locally runs through the City of Charleston’s Stormwater Management division as an MS4 permittee — 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 an approved sanitary sewer connection or licensed facility.

    Official government source

    No permit fee — there is no separate discharge permit for pressure washing; this is an ongoing discharge-prohibition obligation. 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 City of Charleston Stormwater Management before you start work.

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

    South Carolina does not register DBAs. SC Business One Stop states plainly that 'the state of South Carolina does not register DBAs,' and directs businesses to the municipality or county where they operate; Charleston County does not require a general trade-name filing before you can accept jobs under a business name. In practice, use the trade name on your City of Charleston Business License application, list it on your SC Department of Revenue business tax application and on your IRS EIN application, and check the Secretary of State's business name search first. Some banks ask to see it recorded before opening a business account.

    Official government source

    No state filing fee, because there is no state DBA registration. Recording the trade name on your city business license carries no separate charge.No separate filing step or waiting period; the trade name is recorded when you apply for or update your city business license.
