You build a website to bring in customers, not to get into legal trouble. But a single missing label or a low-contrast button can expose you to a website accessibility lawsuit. Demand letters often arrive with little warning and a tight deadline to respond.
Most owners never learn what “accessible enough” means until a letter shows up. That uncertainty is the real problem, not bad intentions. Building an ADA-compliant website is pretty tricky since there are so many grey areas.

What Is a Website Accessibility Lawsuit?
In plain English, a website accessibility lawsuit claims your site blocks someone with a disability from using it. Maybe a screen reader cannot read your menu, or a form has no labels, so a blind shopper cannot check out.Â
The Department of Justice (DOJ) has long applied the Americans with Disabilities Act (ADA) to two groups: state and local governments and any business open to the public.
That includes governments under Title II and businesses under Title III, websites included, according to the DOJ’s own guidance on web accessibility. An ADA website lawsuit usually points to one or two specific barriers, not a long list. Most start as a demand letter, long before anyone sees a courtroom.
7 Accessibility Issues That Commonly Create Risk
Most claims trace back to a short list of recurring issues. More than a quarter of U.S. adults, over 70 million people, live with a disability, according to CDC data. That is a lot of potential customers you might be quietly turning away.
Missing or Poor Image Alt Text
Images without alt text are invisible to screen readers. A product photo with no description tells a blind shopper nothing useful.
Low Color Contrast
Light gray text on a white background looks clean to you. To someone with low vision, it can be unreadable, even on a well-designed site.
Forms Without Labels or Clear Errors
A checkout form with no labels is a guessing game for screen readers. Pair that with a vague error like “invalid input,” and you’ve built a dead end.
Buttons and Menus That Need a Mouse
Not everyone can use a mouse or trackpad. If your dropdown only opens on hover, keyboard users cannot reach your product at all.
Videos Without Captions
A product demo without captions excludes anyone who is deaf or hard of hearing. It is one of the easiest fixes on this whole list.
Headings That Are Styled but Not Coded
Bold, larger text looks like a heading to you, but screen readers need it coded as one, per the Web Content Accessibility Guidelines (WCAG) 2.2 standard for accessible structure. Without that code, your structure disappears for blind users.
Inaccessible PDFs, Popups, and Embeds
A scanned PDF menu or unskippable pop-up can block access like a missing ramp. Plenty of businesses lean on a widget to fix this. The Federal Trade Commission (FTC) fined one vendor $1 million in 2025 for overstating what its widget could do.
Courts generally treat WCAG 2.1 Level AA as the de facto bar for WCAG compliance in Title III cases. That standard, not perfection, is what most settlements actually require.
How These Issues Hurt SEO and AI Search Visibility
These same web accessibility compliance gaps quietly hurt your search rankings and AI visibility. Missing alt text strips away context that search engines and AI tools use to understand your images. Headings that are not coded properly make your page structure harder for both screen readers and search crawlers to follow.Â
Fixing these issues to support ADA website compliance tends to improve usability, clarity, and findability all at once.
What SMBs Should Do Before a Demand Letter Arrives
Start with a real website accessibility audit, not just an automated scanner. Automated tools catch some problems, but they miss most of what actually leads to a lawsuit, like confusing navigation or unclear error handling. Prioritize your highest-traffic ADA compliance website pages first, including your homepage, contact forms, and checkout flows.
If you are a healthcare provider, the Health and Human Services (HHS) has extended its accessibility deadlines. Organizations with 15 or more employees have until May 11, 2027, while smaller ones have until May 10, 2028.
Document every fix you make and note when you made it, since that paper trail matters if a complaint ever lands at your door. Complaints can also go straight to the DOJ’s Civil Rights Division, not just to a plaintiff’s attorney. Add a simple way for visitors to report accessibility problems, since ADA.gov’s own guidance recommends exactly that.Â

Accessibility Is Both Protection and Performance
You do not need to fix everything by next week. Start with the pages that make you money: your homepage, booking form, checkout, and contact page. Each fix lowers your legal exposure, supports website ADA compliance, and makes your site easier for every visitor, disabled or not.
A website accessibility lawsuit is largely preventable. The businesses that treat accessibility as ongoing maintenance, rather than a one-time scramble, tend to be the ones that stay out of the headlines.
