Organizations subject to both the ADA and the European Accessibility Act (EAA) can align their accessibility investments around a single standard: WCAG 2.1 AA. Both laws point to WCAG as the technical benchmark, which means one well-planned accessibility program can address compliance for both regulations at the same time.
The overlap between these two laws is significant. Rather than running parallel programs with separate budgets, the smarter path is a unified approach rooted in WCAG conformance.
| Factor | Detail |
|---|---|
| Shared Standard | Both laws reference WCAG 2.1 AA as the conformance target |
| ADA Technical Standard | WCAG 2.1 AA (codified for Title II; widely applied for Title III) |
| EAA Technical Standard | EN 301 549, which incorporates WCAG 2.1 AA |
| Cost Approach | One audit and remediation cycle can serve both compliance needs |
| Key Investment | A (manual) accessibility audit evaluated against WCAG 2.1 AA or WCAG 2.2 AA |
Why WCAG Is the Common Thread
The ADA does not name a specific technical standard in its original text, but the Department of Justice’s Title II rule codified WCAG 2.1 AA as the required standard for state and local government web content. For Title III (private businesses), WCAG 2.1 AA is the de facto standard referenced in demand letters, settlement agreements, and court filings.
The EAA, which went into effect in June 2025, requires products and services sold in the EU to meet accessibility requirements defined in EN 301 549. That European standard directly incorporates WCAG 2.1 AA for web and mobile content.
This means an organization that conforms to WCAG 2.1 AA has addressed the core technical requirements under both regulatory frameworks. One standard, two compliance obligations covered.
What Does a Unified Accessibility Investment Look Like?
A unified approach starts with a (manual) accessibility audit. This is the only way to determine WCAG conformance. Automated scans are useful for ongoing monitoring, but scans only flag approximately 25% of issues. The audit is the foundation.
From there, the investment follows a predictable sequence:
First, a (manual) audit evaluated against WCAG 2.1 AA (or WCAG 2.2 AA if procurement partners require it). Next, remediation of the issues the audit identifies. Then, validation to confirm fixes were applied correctly. Finally, documentation: an accessibility statement, conformance certification, and an ACR if your product is sold to enterprise or government buyers.
Each of these steps produces assets that work for both ADA compliance and EAA compliance. An audit report showing WCAG 2.1 AA conformance is relevant to a U.S. procurement team and a European buyer alike.
Where the Laws Differ
While the technical standard overlaps, the scope and enforcement mechanisms differ.
The ADA applies to U.S. organizations. Title II covers state and local governments. Title III covers private businesses operating places of public accommodation, which courts have broadly interpreted to include websites. Enforcement comes through lawsuits, demand letters, and Department of Justice actions.
The EAA applies to products and services placed on the EU market. It covers a wide range of digital products: e-commerce sites, banking apps, transportation booking systems, and more. EU member states are responsible for enforcement, and the law applies to companies selling into the EU regardless of where they are headquartered.
For a U.S.-based SaaS company selling into both markets, this distinction matters operationally but not technically. The WCAG conformance work is the same. The documentation may need to be packaged differently: an ACR using the WCAG edition for U.S. buyers, and an ACR using the EN 301 549 edition for EU procurement.
How Should You Prioritize Spending?
The largest line item in any accessibility budget is the audit and remediation cycle. That cost is the same whether you are doing it for ADA compliance, EAA compliance, or both. There is no additional technical work required to cover both laws if your audit is evaluated against WCAG 2.1 AA.
Where additional investment may be needed:
VPAT/ACR documentation: If your product serves both U.S. and EU buyers, you may need ACRs in multiple editions (WCAG edition and EN 301 549 edition). Accessible.org produces ACRs in all four VPAT editions.
Training: Teams that build and maintain digital products need to understand WCAG criteria. One training program covers the technical knowledge needed for both compliance contexts.
Monitoring: Ongoing scans and periodic re-audits keep conformance current. This work should be organized across projects to track progress over time.
The point is that most of the cost is shared. The incremental cost of covering a second regulatory framework when you are already investing in WCAG conformance is small.
What About WCAG 2.2 AA?
WCAG 2.2 AA is the newest version of the standard. Some procurement partners and regulatory bodies are beginning to reference it. The ADA Title II rule currently requires WCAG 2.1 AA, and EN 301 549 also maps to 2.1 AA.
Organizations planning ahead may choose to audit against WCAG 2.2 AA now. Conforming to 2.2 AA automatically includes conformance with 2.1 AA, so there is no downside. It positions the organization ahead of future regulatory updates in both the U.S. and EU.
Accessible.org audits can be conducted against either WCAG 2.1 AA or WCAG 2.2 AA based on client needs.
FAQ
Do I need separate audits for ADA and EAA compliance?
No. A single (manual) audit evaluated against WCAG 2.1 AA covers the technical requirements for both. The audit identifies the same issues regardless of which law is driving the need. You may need separate documentation (different ACR editions), but the underlying evaluation is one audit.
What is the difference between a WCAG edition ACR and an EN 301 549 edition ACR?
The WCAG edition ACR maps your product’s conformance to WCAG criteria directly. The EN 301 549 edition maps conformance to the European standard, which incorporates WCAG but also includes additional requirements for certain product categories like hardware and telecommunications. For most web apps and websites, the WCAG criteria sections are identical between editions.
Can automated scans cover my compliance needs for both laws?
Scans are a useful monitoring tool, but they only flag approximately 25% of accessibility issues. Neither ADA compliance nor EAA compliance can be confirmed through scans alone. A (manual) accessibility audit is the only way to determine WCAG conformance, which is the standard both laws require.
Is my U.S. company subject to the EAA?
If your company sells digital products or services into the EU market, the EAA may apply regardless of where your company is headquartered. This includes SaaS products, e-commerce platforms, and digital services accessible to EU consumers. Legal counsel familiar with EAA requirements can help determine your specific obligations.
One accessibility program, built on WCAG conformance, is the most cost-effective path to meeting both ADA and EAA requirements. The technical work is the same. The documentation is where you customize for each market.
