The Americans with Disabilities Act (ADA) is a U.S. civil rights law that requires equal access to services for people with disabilities. It applies to businesses, government agencies, nonprofits, and any organization that serves the public. This includes websites, which must be accessible to users with visual, auditory, cognitive, or motor impairments.
This article explains what ADA compliance means, who is legally required to comply, how to meet the standards, and common misconceptions to avoid.
ADA compliance ensures that your website is accessible to all users, including those with disabilities. This is based on the Americans with Disabilities Act, which mandates equal access to services and information. For websites, this means ensuring people with visual, auditory, cognitive, or motor impairments can effectively navigate and interact with your site.
To achieve ADA compliance, optimize your website to follow WCAG 2.1 Level AA. Here’s how.
ADA compliance is required for websites that offer goods, services, or information to the public. This includes both private and public sector websites. U.S. courts have consistently ruled that websites are considered places of public accommodation under the ADA when they impact a person’s ability to access essential services or participate in daily life.
ADA requirements apply to any organization that operates a public-facing website, including:
Failing to comply with ADA accessibility standards can result in lawsuits, large settlements, and long-term reputational damage. Under ADA, initial violations can incur up to $75,000 in fines, rising to $150,000 for repeated violations.
Here are some examples of companies sued for not complying with the ADA.
Moreover, noncompliance can disqualify organizations from government contracts or grants that require accessibility adherence.
ADA compliance ensures people with disabilities can use your website fully. It also drives measurable benefits that improve your business and technology outcomes.
Benefits of accessibility include:
A website is accessible when people with disabilities can perceive, operate, understand, and interact with its content, regardless of how they access it. The Web Content Accessibility Guidelines (WCAG) are built around four key principles, known as POUR:
1. Perceivable: Information must be presented in ways users can sense
This means content should be available to all users through various formats. For example:
2. Operable: Users must be able to navigate and interact with all components
Interactive elements must be accessible via keyboard and work without requiring precise movement. This includes:
3. Understandable: Content and interfaces must be easy to follow
Users should not be confused by inconsistent layouts or unclear language. Good practices include:
4. Robust: Content must be compatible with current and future assistive technologies
Your site should be built with clean, semantic HTML and ARIA roles where necessary. For example:
Follow these key steps to align with WCAG 2.1 or 2.2 Level AA, the widely accepted benchmark for ADA compliance:
1. Conduct an accessibility audit using real devices
Begin with a comprehensive evaluation of your website using the BrowserStack Accessibility platform. It gives you access to 3,500+ real devices and browsers, enabling accurate testing across screen sizes, orientations, and OS/browser combinations.
BrowserStack supports both automated and manual testing, including screen reader compatibility checks, to help identify issues in navigation, layout, and content rendering.
2. Use semantic, structured HTML
A strong accessibility foundation starts with clean, semantic code. Use proper heading levels (<h1> to <h6>) to reflect content hierarchy. Implement HTML landmarks (<header>, <nav>, <main>, <footer>) to aid screen reader navigation.
Avoid using generic <div> or <span> tags for interactive elements. Instead, use <button>, <a>, or <input> to preserve native functionality.
3. Add text alternatives for all non-text content
Every meaningful image, icon, chart, and media element must have a text alternative. Use alt attributes for images, label decorative elements with empty alt="", provide captions for videos, and offer transcripts for audio content. Charts and graphs should include textual descriptions of data.
4. Ensure complete keyboard accessibility
All users must be able to navigate and interact with your site using only a keyboard. This includes dropdowns, sliders, modals, buttons, and form fields. Use logical tab order and avoid traps where keyboard focus cannot escape. Clearly visible focus indicators (like outlines or highlights) must be present and never disabled in CSS.
5. Build accessible forms and feedback messages
Form elements should be clearly labeled using <label> tags or aria-label. Group related fields using <fieldset> and <legend>. Error messages must be programmatically associated with the field and announced by screen readers. Indicate required fields and validate inputs in real time with accessible feedback.
6. Use ARIA attributes carefully and only when necessary
ARIA (Accessible Rich Internet Applications) roles and attributes can enhance accessibility but should not replace semantic HTML. Use ARIA to define roles, states, and properties for custom widgets like accordions or tabs, but always test behavior with screen readers. Avoid overuse, which can introduce confusion.
7. Maintain consistent structure and navigation patterns
Use a predictable layout across all pages. Navigation menus, search bars, and interactive components should appear in the same order throughout the site. This benefits users with cognitive disabilities and helps screen reader users orient themselves efficiently.
8. Test regularly using assistive technology and diverse input methods
Use screen readers like NVDA, JAWS, or VoiceOver to test your site’s output. Navigate using only the keyboard to identify traps or inaccessible elements. Simulate color blindness, low vision, and other user conditions.
Misunderstanding what ADA compliance involves can lead to partial fixes, ongoing barriers, or legal risk. Below are common myths and the facts organizations need to get right.
ADA requires equal access for people with disabilities. It applies to any organization with a public-facing website in the U.S., including businesses, government agencies, and nonprofits. To comply, follow WCAG standards, test on real devices, and remove accessibility barriers across your site. This ensures usability for all and protects against legal and operational risks.
