Key point: The law, which went into effect at signing, contains significant design and development requirements, requires independent third-party audits, and can be enforced against officers and employees.
On February 5, 2026, South Carolina Governor Henry McMaster signed the South Carolina Age-Appropriate Design Code Act (H 3431). South Carolina now joins California, Maryland, Nebraska, and Vermont in enacting Age-Appropriate Design Code (AADC) laws although these laws vary widely in both scope and requirements.
South Carolina’s law has several unique requirements, including requiring covered online services to engage in independent third-party audits, which are to be publicly posted by the state attorney general. We review these requirements below.
Of further note, the law went into effect upon the governor’s signature and does not contain a right to cure. The law is generally enforceable by the state attorney general who can seek treble financial damages for violations. The law also specifically provides that officers and employees of covered online services can be held personally liable for willful and wanton violations. In addition, the law’s prohibition against dark patterns is enforceable under the South Carolina Unfair Trade Practices Act, which allows for a private right of action. In the below post, we provide an overview of the new law and provide more general context on its provisions.
