STATE LICENSE
ConditionalClemson University Department of Pesticid…
Landscaping, land clearing, irrigation (except the backflow device), and most fencing are on the CLB's 'no specific license required' list; landscaping is not among the Residential Builders Commission's specialty classifications either. Regulated pieces of a landscape job — concrete, masonry walls, electrical connections — still need the matching CLB classification when that regulated work exceeds $10,000.
The real credential is pesticides. Applying any pesticide, general or restricted use, to ornamentals and turf for hire requires a commercial applicator license in Category 3 (Ornamental and Turf) from Clemson University's Department of Pesticide Regulation, backed by $50,000 of liability insurance with a $100,000 annual aggregate (S.C. Code §§ 46-13-60, 46-13-100; DPR FAQ).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
With no state landscaping license, the local layer is the business license tax (§ 6-1-400: May 1 – April 30) plus building permits for any structures such as retaining walls or regulated hardscape, where § 40-11-350 requires the permit desk to see a CLB license if the regulated work exceeds $10,000. The same rules apply in the City of Charleston, Columbia, Greenville, or Myrtle Beach and in unincorporated Charleston, Richland, Greenville, or Horry County.
The local offices section below names the exact permit desk for every South Carolina county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Mowing, planting, grading, land clearing and irrigation (other than the backflow device) need no state trade license.
Clemson's pesticide business license applies only to Category 7A structural pest control; lawn-care companies need licensed applicators, not a business license.
Applicator licenses expire December 31; renewing late adds 25%, and missing April 1 means re-examination (§ 46-13-80).

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Wilfully working without the appropriate commercial applicator license is a misdemeanor, escalating with repeat offenses.
Anyone paid to apply pesticides who violates the act may be assessed a civil penalty by the director.
Bundling regulated concrete, masonry, or backflow work over $10,000 into a landscape job without the CLB license is unlicensed contracting.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
Every fact in this file was checked against these official sources on October 2026.
