ADA — Americans with Disabilities Act and Web Accessibility

In this tutorial, you will learn about ADA. We cover key concepts, practical examples, and best practices to help you master this topic.

The Americans with Disabilities Act (ADA) Title III prohibits discrimination on the basis of disability in places of public accommodation, which courts increasingly interpret to include websites, with WCAG 2.1 AA as the de facto standard.

What You'll Learn

You will learn how the ADA applies to websites, who must comply, what the legal risks are, and how to build a Compliance Strategy for your organization.

Why It Matters

ADA website lawsuits exceeded 4,000 in 2024 and continue to grow. Average settlements exceed 50,000 dollars. Understanding ADA requirements is essential for any US-based business with a public-facing website.

Real-World Use

DodaTech's Durga Antivirus Pro website is designed to meet WCAG 2.2 AA, exceeding the ADA's de facto standard. This proactive approach reduces legal risk and opens the product to enterprise customers who require ADA compliance.

What Is the ADA?

The Americans with Disabilities Act was signed into law in 1990. Title III prohibits discrimination on the basis of disability by places of public accommodation. While the law predates the commercial web, courts have consistently applied it to websites.

Places of Public Accommodation

The ADA lists 12 categories of public accommodation including hotels, restaurants, theaters, stores, banks, hospitals, and museums. Courts have interpreted websites of these businesses as extensions of their physical locations.

Who Must Comply

Any business open to the public in the United States. This includes retail, hospitality, banking, healthcare, entertainment, and professional services. There is no small business exemption for websites.

Who Is Exempt

Private clubs and religious organizations are exempt. Internal intranets and SaaS products without public access may have a weaker case for coverage.

The WCAG Connection

The ADA does not mention WCAG. However, courts and the Department of Justice have used WCAG 2.1 Level AA as the standard for measuring compliance. Meeting WCAG AA provides a strong legal defense.

function assessADARisk(siteFeatures) {
  const risks = [];
  if (!siteFeatures.hasAltText) risks.push('Missing alt text on images');
  if (!siteFeatures.hasKeyboardSupport) risks.push('No keyboard navigation');
  if (!siteFeatures.hasContrast) risks.push('Insufficient color contrast');
  if (!siteFeatures.hasCaptions) risks.push('Missing video captions');
  if (!siteFeatures.hasLabels) risks.push('Form inputs without labels');
  return {
    riskLevel: risks.length === 0 ? 'Low' : risks.length <= 2 ? 'Medium' : 'High',
    issuesFound: risks.length,
    details: risks
  };
}

const mySite = {
  hasAltText: true,
  hasKeyboardSupport: false,
  hasContrast: true,
  hasCaptions: true,
  hasLabels: true
};

console.log(assessADARisk(mySite));

Expected output:

{ riskLevel: 'Medium', issuesFound: 1, details: ['No keyboard navigation'] }

Penalties

First violation civil penalties up to 75,000 dollars. Second violation up to 150,000 dollars. Plaintiff attorneys fees and settlement costs average 50,000 dollars plus per case.

Demand Letters

Many ADA cases start with a demand letter from a plaintiffs firm. The letter describes specific barriers found on your website and demands remediation within a deadline. Responding seriously to demand letters often reduces settlement costs.

Common Mistakes

1. Assuming ADA Does Not Apply to Websites

Courts have consistently ruled that websites of public accommodations are covered. This is settled law.

2. Thinking Small Businesses Are Exempt

There is no small business exemption for ADA Title III as applied to websites. Small businesses are frequent targets.

3. Ignoring Demand Letters

Ignoring a demand letter leads to a lawsuit with higher costs. Respond promptly and engage legal counsel.

4. Claiming Undue Burden Without Documentation

The undue burden defense requires documented analysis of cost and resources. A vague claim of burden will not hold up.

5. Not Fixing Issues After a Lawsuit

Settlements often require ongoing compliance. Fixing issues temporarily and letting them recur invites further litigation.

6. Relying on Automated Tools Alone

A perfect WAVE score does not guarantee ADA compliance. Manual testing and user testing are required.

7. Forgetting Mobile Apps

ADA applies to mobile apps of public accommodations. Mobile Accessibility is equally important.
