ADA Website Compliance Checklist for 2026 (Plain-English, With Free Tools)
ADA Website Compliance Checklist for 2026
Thousands of US businesses get ADA website demand letters every year, and the targets are mostly not tech giants: they're restaurants, dental clinics, e-commerce shops, and small SaaS companies. Meanwhile the European Accessibility Act now applies to anyone selling to EU consumers. If you own a website that sells something or serves customers, accessibility stopped being optional.
This checklist is written for business owners, not developers. Twelve checks, in plain English, with a free tool or a 30-second manual test for each one. It won't make you a lawyer or an auditor, but it will tell you roughly where you stand and whether you have a problem worth acting on.
First, the two facts that frame everything:
- Courts apply WCAG. The ADA doesn't name a technical standard, but US courts and the DOJ consistently treat WCAG 2.1 Level AA as the benchmark. That's the standard this checklist points at.
- Overlay widgets don't protect you. The "accessibility widget" plugins that promise one-line compliance are named in lawsuits themselves. There's no shortcut around actually fixing your site.
The 12-Point Checklist
1. Every image has meaningful alt text
Screen readers speak the alt text; without it, images are silence or filename gibberish. Decorative images should have empty alt text so they're skipped.
Test it: run our free accessibility checker on your homepage; it flags missing alt text instantly.
2. The whole site works with only a keyboard
Unplug your mouse. Tab through your site. Can you reach every menu, open every dropdown, and complete a purchase or contact form using only Tab, Enter, and arrow keys? Many motor-impaired users navigate exactly this way.
Test it: 2 minutes, no tools. If you get stuck anywhere or lose track of where you are, that's a violation.
3. You can always see where keyboard focus is
As you tab, a visible outline should show which element is active. Designers often remove it because it "looks ugly." Removing it makes the site unusable for keyboard users.
Test it: while tabbing, watch for the outline. If it vanishes on buttons or links, it's broken.
4. Text contrast passes 4.5:1
Light gray text on white backgrounds is the most common failure on the web. WCAG requires a 4.5:1 contrast ratio for normal text, 3:1 for large text.
Test it: our color contrast checker checks any color pair in seconds.
5. Forms have visible labels and helpful errors
Every input needs a label that stays visible (placeholder text that disappears doesn't count). When something's wrong, the error must say what and where, and screen readers must announce it.
Test it: submit your contact form empty. Is it obvious, to eyes and to a screen reader, what needs fixing?
6. Color is never the only signal
"Fields in red are required." "Green means in stock." A colorblind user sees nothing. Every color signal needs a second channel: text, an icon, an underline.
Test it: screenshot your site in grayscale and check whether all the information survives.
7. Videos have captions
Any video with speech needs accurate captions (auto-captions usually don't qualify). Audio-only content needs a transcript.
8. Headings are structured, not just styled
Screen reader users navigate by heading structure: one H1 per page, H2s for sections, no skipped levels. Text that's just styled big and bold isn't a heading to assistive tech.
Test it: our accessibility checker maps your heading structure.
9. Links say where they go
"Click here" and "read more" are meaningless in a screen reader's link list. Link text should describe the destination.
10. Nothing traps or auto-plays
Auto-playing audio, carousels that can't be paused, and modals you can't escape with the keyboard are all violations, and genuinely hostile to everyone.
11. The site works at 200% zoom
Low-vision users zoom. At 200%, text must remain readable and functions usable, with no content cut off or overlapping.
Test it: press Ctrl/Cmd + until you hit 200%. Click around.
12. You have an accessibility statement
A page stating your conformance target, known limitations, and a contact for accessibility problems. The EU Accessibility Act expects one; in the US it signals good faith, and good faith matters when a demand letter arrives.
What This Checklist Can't Do
Honesty time: these 12 checks catch the most common and most-litigated failures, and passing them puts you ahead of most of the web. But automated tools and self-checks can only verify about 30% of WCAG 2.1 AA criteria. The rest — focus order that makes sense, custom components that announce correctly to screen readers, reading order, complex form flows — requires a human tester with assistive technology.
So the honest playbook is:
- Self-check with this list (free, today)
- Run the automated scans on your key pages (free, accessibility checker and WCAG compliance checker)
- Get a manual audit if you sell online, serve the EU, face procurement questionnaires, or received a demand letter — that's the 70% the tools can't see
For the third step, that's a service we provide: manual WCAG 2.1 AA audits with a developer-ready fix list, from $499, typically 1-2 weeks, with remediation available if you want it fixed for you. Details at accessibility audit services.
Frequently Asked Questions
Is my website legally required to be ADA compliant?
If your US business serves the public, the safest assumption is yes. Courts have repeatedly treated websites as "places of public accommodation" under Title III of the ADA, and the DOJ's position supports web accessibility. Separately, the European Accessibility Act applies to e-commerce and consumer services sold into the EU since June 2025. This isn't legal advice; a lawyer can assess your specific exposure.
What standard do I need to meet for ADA compliance?
WCAG 2.1 Level AA is the de facto standard: it's what courts reference, what the DOJ cites in settlements, and what the EU Accessibility Act's harmonized standards build on. WCAG 2.2 adds a few criteria and is worth targeting on new builds.
Do accessibility overlay widgets make my site compliant?
No. Overlay vendors have themselves been named in hundreds of lawsuits, and disability advocates broadly oppose them because they don't fix the underlying code. Money spent on an overlay is better spent fixing the actual issues, which is often less work than expected.
How much does ADA website compliance cost?
Self-checking with free tools costs nothing. A professional manual audit of a typical small-business site starts around $499 (that's our price; the industry ranges to $5,000+). Remediation depends entirely on what's broken: a site with decent bones often needs days of work, not months. The expensive path is ignoring it until a demand letter sets your timeline.
What happens if I get an ADA demand letter?
Don't ignore it, and don't panic-buy an overlay. Typical steps: talk to a lawyer, get a real audit fast so you know your actual exposure, fix the issues, and document the work. Most cases settle; documented remediation dramatically strengthens your position.
The Honest Take
ADA compliance has a reputation as a legal minefield, but the work itself is mostly craftsmanship: labels on forms, contrast in text, keyboards that work. The 12 checks above are a real start, the free tools cover the scannable parts, and a manual audit covers the rest.
