ADA Website Compliance Checker — Free Accessibility Scanner

The Americans with Disabilities Act (ADA) requires businesses that serve the public to make their websites accessible to people with disabilities. Courts have consistently ruled that websites qualify as “places of public accommodation” under Title III of the ADA. If your website has accessibility barriers, you could face a demand letter, lawsuit, or settlement costs ranging from $5,000 to $75,000 or more. Using a free ADA compliance checker to identify and fix violations before a plaintiff finds them is the most cost-effective legal risk mitigation available.

AccessScore is a free ADA website compliance checker that scans your site against WCAG 2.1 Level AA standards — the benchmark courts reference in virtually every ADA web accessibility case. Enter your URL, get your score (0-100), see every violation with exact fix code, and understand your legal risk tier. No signup required. No email gate. Results in seconds.

What Does ADA Website Compliance Mean?

ADA website compliance means ensuring that people with disabilities — including those who are blind, deaf, have motor impairments, or cognitive disabilities — can perceive, understand, navigate, and interact with your website. The technical standard courts most commonly reference is the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA.

WCAG 2.1 AA requires your website to meet criteria across four principles, often remembered by the acronym POUR:

• Perceivable — Information must be presentable in ways users can perceive. This includes alt text for images, captions for video, and sufficient color contrast.
• Operable — Interface components must be operable via keyboard, have adequate time limits, and not cause seizures. Navigation must be predictable.
• Understandable — Content must be readable and predictable. Forms must provide input assistance and error identification.
• Robust — Content must be compatible with assistive technologies like screen readers, magnifiers, and voice control software.

An ADA compliant website checker tests your pages against these principles by examining the HTML, ARIA attributes, heading structure, form labels, link text, media elements, and interactive components that assistive technologies rely on.

What This ADA Compliance Website Checker Tests

AccessScore runs 50+ automated checks across six critical categories. Here is what our ADA accessibility checker evaluates on every scan:

Who Needs an ADA Website Compliance Checker?

Any business that operates a website and serves customers in the United States should regularly run an ADA compliance website checker. This includes:

Even small businesses with fewer than 15 employees have been successfully sued for website accessibility violations. In fact, 67% of ADA web lawsuits target businesses with under $25 million in revenue. If your website accepts orders, processes payments, or provides information about your services, it falls under ADA Title III — and you should be using an ADA compliant website checker regularly.

ADA Website Lawsuit Statistics (2024-2026)

How to Fix ADA Compliance Issues Found by the Checker

After running the AccessScore ADA website scanner, you will receive a list of violations ordered by severity and legal impact. Here is how to approach remediation:

Priority 1: Critical Violations (Fix Immediately)

These are the violations most frequently cited in ADA lawsuits and demand letters. Fixing these first provides the greatest reduction in legal risk:

• Missing image alt text — The #1 cited violation. Every <img> needs a descriptive alt attribute. Decorative images should use alt="".
• Missing form labels — Every input field needs an associated <label> element or aria-label attribute.
• Empty links and buttons — Interactive elements must have accessible text content or aria-label.
• Missing page language — Add lang="en" (or appropriate language code) to your <html> element.

Priority 2: High-Impact Violations

• Insufficient color contrast — Text must meet 4.5:1 ratio (3:1 for large text). Use a contrast checker tool.
• Missing skip navigation — Add a "Skip to main content" link as the first focusable element.
• Broken heading hierarchy — Headings should follow a logical order (H1, then H2, then H3). Do not skip levels.
• Viewport zoom disabled — Remove maximum-scale=1 and user-scalable=no from your viewport meta tag.

ADA Compliance Checking for Developers

Beyond the web-based ADA website compliance checker, AccessScore integrates directly into development workflows:

Legal Background: Why ADA Website Compliance Matters

The legal foundation for ADA website compliance has been established through several landmark court decisions and Department of Justice (DOJ) actions:

• DOJ Final Rule (April 2024) — The DOJ published a final rule under Title II requiring state and local government websites to conform with WCAG 2.1 Level AA. While Title III (private businesses) has no identical rule yet, this signals clear DOJ direction.
• Robles v. Domino's Pizza (2019) — The Ninth Circuit ruled that the ADA applies to websites and mobile apps of businesses with physical locations. The Supreme Court declined to hear the appeal, letting the ruling stand.
• Gil v. Winn-Dixie (2021) — The Eleventh Circuit ruled that websites must have a "nexus" to a physical location. This created a circuit split that increases legal uncertainty — another reason to proactively ensure compliance.
• California Unruh Act — Provides minimum damages of $4,000 per violation per visit. California leads in ADA web lawsuit filings, making compliance especially critical for businesses serving California residents.
