South Carolina AADC Compliance Guide: Navigating Age-Appropriate Design Code Requirements for 2026

Introduction: Understanding South Carolina's Age-Appropriate Design Code

South Carolina's Age-Appropriate Design Code (AADC), enacted as HB 3431 and signed by Governor McMaster on February 5, 2024, represents a paradigm shift in youth online protection frameworks. Unlike traditional data privacy laws that focus on mitigation, this law imposes a heightened 'duty of care' requiring organizations to prevent risks like compulsive use, severe psychological harm, identity theft, and discrimination for minors. The law took effect immediately upon approval, creating urgent compliance needs for covered entities, with significant implications for 2026 operations. This guide provides actionable steps to navigate the South Carolina AADC, comparing it to other U.S. state privacy and AI laws, and outlining a phased approach to compliance.

Key Provisions of South Carolina's AADC Law

South Carolina HB 3431 introduces several novel requirements that go beyond typical state privacy laws:

• Scope: Applies to any legal entity (including non-profits) providing online services 'reasonably likely to be accessed by minors' meeting specific thresholds (e.g., $25M+ revenue or data on 50,000+ individuals).
• Duty of Care: Requires prevention of harms to minors, setting a higher bar than mitigation-focused laws like the California CPRA or Colorado CPA.
• Universal Default Tools: Mandates default settings that protect minors, such as privacy controls and time limits.
• Parental Monitoring: Includes prescriptive requirements for parental oversight features.
• Annual Third-Party Audits: Replaces internal Data Protection Impact Assessments (DPIAs) with mandatory audits, with results publicly reported by the Attorney General.
• Enforcement: Allows personal liability for employees in cases of 'willful and wanton' violations, a novel approach in U.S. privacy law.

Note: NetChoice filed a lawsuit challenging the law's constitutionality on February 9, 2024, creating compliance uncertainty. Organizations should monitor legal developments while preparing for potential enforcement.

Comparison to Other U.S. State Privacy and AI Laws

South Carolina's AADC differs significantly from other state regulations, reflecting broader trends in AI and privacy governance.

U.S. State Privacy Laws

As of 2025, 15+ U.S. states have enacted comprehensive privacy laws, but none match the AADC's child-specific duty of care:

• California CPRA: Effective January 1, 2023, focuses on consumer rights (access, deletion) without specific child prevention mandates.
• Colorado CPA: Effective July 1, 2023, includes data protection assessments but not the prescriptive safeguards for minors.
• Virginia VCDPA: Effective January 1, 2023, lacks the universal default tools and third-party audit requirements.

For more on evolving privacy frameworks, see our guide to EU data regulations.

U.S. State AI Laws

From 2023 to 2025, 27 AI-related laws were enacted across 14 U.S. states, shifting toward sector-specific regulations:

• Colorado AI Act (SB 24-205): Effective February 1, 2026, requires reasonable care to avoid algorithmic discrimination for high-risk AI, similar to the AADC's duty of care but broader in scope.
• NYC Local Law 144: Effective July 5, 2023, mandates bias audits for automated employment decision tools, focusing on hiring rather than child protection.
• Illinois AI Video Interview Act: Effective January 1, 2020, requires consent for AI-analyzed video interviews, a narrower application.

These laws highlight a trend toward targeted governance, as discussed in our healthcare AI compliance guide.

Prerequisites for AADC Compliance

Before starting the compliance steps, ensure your organization has:

1. Determined Applicability: Assess if your online services are 'reasonably likely to be accessed by minors' and meet revenue or data thresholds.
2. Legal Review: Consult with legal counsel to understand the law's requirements and monitor the NetChoice lawsuit.
3. Cross-Functional Team: Involve privacy, legal, product, and IT teams to implement safeguards.
4. Budget for Audits: Plan for annual third-party audit costs, which replace internal DPIAs.

Tools like AIGovHub can assist in tracking state-level privacy regulations and automating compliance workflows, reducing manual effort.

Step 1: Risk Assessment for Data Practices Affecting Minors

Conduct a thorough risk assessment to identify potential harms to minors, as required by the AADC's duty of care.

Actions to Take:

• Map Data Flows: Document all data collection, processing, and sharing involving minors. Use privacy management platforms like OneTrust or Securiti AI to automate mapping.
• Identify High-Risk Areas: Focus on features that could lead to compulsive use, psychological harm, or discrimination. For example, social media algorithms or gaming mechanics.
• Benchmark Against Standards: Compare practices to frameworks like the NIST AI Risk Management Framework (AI RMF 1.0), which includes Govern, Map, Measure, and Manage functions, though note it's voluntary in the U.S.
• Document Findings: Create a risk register detailing identified harms and prevention strategies.

This step aligns with broader AI governance trends, as seen in the EU AI Act compliance roadmap.

Step 2: Design and Implementation of Age-Appropriate Safeguards

Implement technical and organizational measures to prevent harms, focusing on universal default tools and parental monitoring.

Actions to Take:

• Default Privacy Settings: Configure all services to maximize privacy for minors by default, such as disabling location tracking or limiting data sharing.
• Time and Usage Limits: Integrate features that prevent compulsive use, like automatic session timeouts or daily usage caps.
• Parental Controls: Develop tools for parents to monitor and restrict activities, as prescribed by the law. Ensure these are easy to use and accessible.
• Age Verification: Implement robust age estimation or verification mechanisms to identify minor users without collecting excessive data.
• Product Design Reviews: Incorporate child safety into product development cycles, similar to requirements under the EU AI Act for high-risk AI systems.

Step 3: Documentation and Audit Trails

Maintain comprehensive records to demonstrate compliance and prepare for annual third-party audits.

Actions to Take:

• Create Compliance Documentation: Document all risk assessments, design decisions, and safeguard implementations. Use tools like Securiti AI for automated record-keeping.
• Prepare for Audits: Engage a qualified third-party auditor annually. Ensure reports are ready for public disclosure by the Attorney General, as required.
• Employee Training Records: Train staff on the AADC requirements and document sessions to mitigate personal liability risks.
• Incident Logs: Track any incidents involving minors and corrective actions taken, aligning with frameworks like NIST Cybersecurity Framework 2.0 for detection and response.

This mirrors documentation needs under other regulations, such as EU AI Office requirements.

Step 4: Ongoing Monitoring and Updates

Continuously monitor compliance and update practices based on legal changes and operational feedback.

Actions to Take:

• Regular Reviews: Conduct quarterly reviews of safeguards and data practices to ensure they remain effective.
• Stay Informed on Legal Challenges: Monitor the NetChoice lawsuit and any amendments to the AADC, as outcomes could affect compliance obligations.
• Update for New Risks: Adapt to emerging threats, such as generative AI chatbots, which are a focus in 2025 state AI laws. For example, ensure transparency and safety protocols for AI interactions with minors.
• Leverage Compliance Tools: Use platforms like AIGovHub to track regulatory updates across states, including phased effective dates like Colorado's AI Act in 2026 or California's amendments through 2028.

Common Pitfalls to Avoid

• Ignoring the Duty of Care: Focusing only on mitigation rather than prevention of harms, which violates the AADC's core requirement.
• Underestimating Scope: Assuming the law doesn't apply due to revenue thresholds, without considering the 'reasonably likely' access test.
• Neglecting Employee Liability: Failing to train employees on 'willful and wanton' violation risks, leading to personal liability exposures.
• Overlooking Audit Costs: Not budgeting for mandatory third-party audits, which can be more costly than internal DPIAs.
• Static Compliance: Treating implementation as a one-time project without ongoing monitoring, missing updates from legal challenges or new risks.
