ADA Compliance

How to Make Your Website ADA Compliant

An ADA-compliant website is one that conforms to WCAG 2.1 Level AA, the Web Content Accessibility Guidelines published by the W3C Web Accessibility Initiative. The U.S. Department of Justice has identified WCAG 2.1 AA as the standard for accessibility under the Americans with Disabilities Act, Title III.

What ADA compliance actually requires

WCAG 2.1 contains 50 success criteria at Level A and Level AA combined, organized under four principles the W3C calls POUR.

  • Perceivable. Content must be presentable to users in ways they can perceive. Alt text on images. Captions on video. Sufficient color contrast (4.5:1 for normal text).
  • Operable. Interface components must be usable. Every function reachable by keyboard. No content that flashes more than three times per second. Users can extend time limits.
  • Understandable. Content and interface behavior must be predictable. Labels on every form field. Errors identified in text, not color alone. Language of the page declared.
  • Robust. Content must work reliably with current and future assistive technologies. Valid HTML. Proper ARIA roles. No markup that breaks screen readers.

WCAG 2.2, published by W3C in October 2023, adds nine additional success criteria on top of WCAG 2.1. The DOJ currently points to WCAG 2.1 AA as the enforceable floor. Most businesses that target WCAG 2.1 AA now are well-positioned for whatever the DOJ settles on next.

WCAG Level A vs AA vs AAA: which does your business need?

LevelSuccess CriteriaWhat it coversUse case
A30Minimum floor. Basic keyboard access, alt text, no seizure triggers.Nothing relies on Level A alone. Always combined with AA.
AA20 (50 cumulative)Standard most regulations reference. Contrast, resize, consistent navigation.DOJ-identified standard under ADA Title III. Target for almost every business.
AAA28 (78 cumulative)Highest bar. Sign language for video, 7:1 contrast, reading-level guidance.Only required in narrow contexts. W3C notes AAA is not required as a general policy.

What triggers an ADA website lawsuit

More than 4,000 federal ADA Title III lawsuits over website accessibility were filed in 2024, according to UsableNet's year-end tracking. The pattern is predictable. Plaintiff firms run automated scans against thousands of sites a week. They sort the results. They file.

The five failures that drive most of the volume:

  1. Missing or empty alt text on images. Screen readers cannot describe a product photo that says <img src="shoe.jpg"> with no alt attribute.
  2. Keyboard traps. A modal or menu that traps focus and cannot be closed with the Escape key.
  3. Insufficient color contrast. Light gray text on a white background. WCAG AA requires 4.5:1 for normal text and 3:1 for large text.
  4. Forms without labels. A checkout page where the email field is unlabeled and invisible to a screen reader.
  5. Inaccessible PDFs. A menu or price list uploaded as an image-only PDF, unreadable by any assistive technology.

If your site has any of these and you sell to the public, you are the profile of a plaintiff firm's next lawsuit. The WebAIM Million 2024 report found detectable WCAG failures on 95.9% of home pages surveyed. Most sites fail the same five criteria. Fix those five first.

Can I make my website ADA compliant myself?

Honestly, no. WCAG 2.1 AA has 50 success criteria, and automated tools catch roughly a third of them. The rest require manual expert review: keyboard testing, screen reader testing, reading-order audits, focus-order audits, semantic review of custom components.

“Automated accessibility testing is a good starting point, but it cannot replace human evaluation. Many WCAG success criteria require judgment that only a trained evaluator can provide.”

Deque Systems, axe-core documentation

You can install a free scanner (ours is below) and catch the obvious failures yourself. You can fix alt text, contrast, and form labels from an engineering backlog. What you cannot do from a scanner alone is certify compliance. That takes manual testing against all 50 criteria, a report that names each failure and its fix, and usually a retest after remediation.

What a professional ADA audit includes

We deliver four things:

  1. A full manual audit against WCAG 2.1 AA. Every page type, every interactive component, every form. Scanner findings verified by hand and expanded with what automation missed.
  2. A prioritized remediation plan that separates lawsuit-critical failures (the top five) from polish work. Most sites fix the top five first, cover 80% of the lawsuit risk, and work the remainder on a reasonable schedule.
  3. A developer-ready report naming each failure, the WCAG criterion it violates, where in the code it lives, and the fix. Not a PDF dump. A working punch list.
  4. A retest after remediation and an accessibility statement your legal team can stand behind.

One opinion, stated plainly: most sites fail the same five criteria. Fix those five before anything else. Anything that delays the top-five fix is the wrong priority.

How long does ADA remediation take?

For a typical small-to-mid-size website, expect two to six weeks end to end. The split:

  • Week 1: Full audit and report delivery.
  • Weeks 2 to 4: Developer remediation of the top issues, usually driven by your own engineering team or ours.
  • Week 5 or 6: Retest, accessibility statement, sign-off.

Sites with heavy custom UI, large PDF libraries, or video archives without captions trend to the longer end. Sites built on a modern framework with sensible component choices usually finish closer to two weeks.

Run our free ADA scanner first

Before a paid engagement, run our free ADA scanner. It checks your site against WCAG 2.2 Level AA criteria, returns a letter grade, and lists every detected failure. No login. It’s a diagnostic tool. If it comes back clean, you’re probably in good shape. If it flags the top five categories above, you have a lawsuit-risk problem and you should talk to us.

Frequently asked questions

Is ADA compliance legally required for my website?

For most businesses that serve the public, yes. The Department of Justice has held since 2022 that ADA Title III applies to the websites of public accommodations. Federal courts in multiple circuits have ruled that websites of brick-and-mortar businesses fall under Title III. State laws (California's Unruh Act, New York's State Human Rights Law) add enforcement on top.

What is the difference between WCAG 2.0, 2.1, and 2.2?

WCAG 2.0 (2008) covered the original baseline. WCAG 2.1 (2018) added 17 success criteria focused on mobile, low vision, and cognitive accessibility. WCAG 2.2 (October 2023) added nine more, most of them Level AA. The DOJ references WCAG 2.1 AA as the current standard. WCAG 2.2 AA is a superset and is the direction most organizations are moving.

How much does an ADA audit cost?

It depends on site size, complexity, and how much custom UI there is. Small brochure sites start around the low four figures. Mid-size sites with heavy interaction, checkout, or account flows are typically five figures. We scope every engagement in a free discovery call so you see the number before you commit.

What happens if my website isn't ADA compliant?

Worst case: a Title III lawsuit. Best case: you lose sales from roughly 27% of U.S. adults who live with a disability (CDC, 2024) who can't complete a purchase. Either way, the cost of being non-compliant is higher than the cost of an audit.

Do I need ongoing accessibility audits?

If your site changes, yes. Every new feature, redesign, and third-party plugin is a chance to reintroduce an accessibility bug. Most of our clients schedule a yearly retest and a spot-check after any major release.

Will an overlay widget make my site ADA compliant?

No. Overlay and toolbar widgets do not fix the underlying code. Every major plaintiff firm has published opinions stating that overlays are not a defense against a Title III lawsuit. The only path to real compliance is fixing the code.

Can I just get a scan and call it done?

A scan is a diagnostic, not a certificate. A pass on an automated scan does not mean your site is compliant. It means automation didn't find anything. Certification requires manual testing against the full 50-criterion WCAG 2.1 AA checklist.
