ADA Website Lawsuits: How to Protect Your Business Before a Demand Letter Arrives

A law firm in New York files an ADA website accessibility lawsuit every 47 minutes during business hours. That is not an exaggeration — it is math based on the volume of filings from the top 10 plaintiff firms in 2024. Over 4,600 ADA web accessibility lawsuits were filed in 2023, up from 2,314 in 2018. The trajectory has only accelerated. If your website is not accessible to people with disabilities, the question is not whether you are at risk — it is how long before a plaintiff's firm adds you to the list.

This article covers the lawsuit landscape, which businesses get targeted, the specific risk factors that make you visible to serial plaintiff firms, and the concrete steps to protect your business before a demand letter arrives. This is not legal advice — it is an operational guide from Revenue Group's experience remediating accessibility issues for dozens of client sites. For a full compliance service overview, see our ADA website compliance services.

The ADA Web Accessibility Lawsuit Landscape

Title III of the Americans with Disabilities Act prohibits discrimination in places of public accommodation. Federal courts — particularly in the Second, Ninth, and Eleventh Circuits — have consistently ruled that websites qualify as places of public accommodation, meaning they must be accessible to people with disabilities. The legal standard courts most frequently reference is WCAG 2.1 Level AA, the Web Content Accessibility Guidelines published by the World Wide Web Consortium. While the ADA does not explicitly name WCAG, the Department of Justice issued a final rule in April 2024 requiring state and local government websites to conform to WCAG 2.1 AA, and courts have increasingly applied the same standard to private businesses.

The plaintiff bar has industrialized this area of law. A small number of firms and individual plaintiffs account for the majority of filings. The top 10 plaintiff firms filed over 60% of all ADA web accessibility lawsuits in 2023. These firms use automated scanning tools to identify websites with accessibility violations, then file lawsuits in bulk. The business model is volume: file hundreds of cases, settle each for $5,000 to $25,000, and move on to the next batch. The cost of defending a single lawsuit — even if you win — typically exceeds the cost of settling, which is why 95% of cases settle before trial.

Which Businesses Get Targeted and Why

E-commerce websites account for approximately 65% of all ADA web accessibility lawsuits. The reason is straightforward: online stores have transactional functionality (product browsing, shopping carts, checkout flows) that creates concrete barriers for users with disabilities. A screen reader that cannot parse product descriptions, a checkout form without proper labels, or an image carousel without alt text creates a documentable inability to complete a purchase — exactly the kind of barrier that makes a strong legal claim.

After e-commerce, the most targeted industries are food service and hospitality (restaurants with online menus and reservation systems), banking and financial services (account access and application forms), healthcare (patient portals and appointment scheduling), and entertainment (ticket purchasing and event information). The common thread: these industries have customer-facing websites where inaccessibility prevents a disabled user from completing a transaction or accessing a service that non-disabled users can access freely.

Business size is not a shield. While large retailers receive the most headline-generating lawsuits, 73% of ADA web accessibility lawsuits target businesses with less than $25 million in annual revenue. Small businesses are attractive targets because they are less likely to have legal counsel on retainer, more likely to settle quickly, and less likely to have proactively addressed accessibility. Revenue Group has seen demand letters sent to businesses with fewer than 10 employees and websites with fewer than 20 pages.

The Seven Risk Factors That Make You a Target

Plaintiff firms use automated scanning tools to identify potential targets. The following seven factors increase your likelihood of being flagged:

• No alt text on images. The single most common WCAG violation and the easiest for automated tools to detect. If your images lack alt text, your site is visible to every scanning tool used by plaintiff firms.
• No accessibility statement. The absence of an accessibility statement signals that the business has not considered accessibility at all — making it a likely candidate for multiple violations beyond the missing statement.
• E-commerce functionality. Shopping carts, product filters, checkout forms, and account creation flows are high-complexity interactive elements that are frequently inaccessible. An inaccessible checkout creates a clear, documentable barrier.
• PDF content without accessible formatting. Restaurant menus, service brochures, and price lists published as image-based PDFs are completely invisible to screen readers. For full compliance requirements, see our ADA compliance checklist.
• Third-party widgets. Chat widgets, booking systems, review embeds, and social media feeds often inject inaccessible HTML into your page. You are legally responsible for all content on your site, including third-party components.
• No keyboard navigation. Sites that require a mouse for navigation exclude users who rely on keyboards, switch devices, or voice control. Dropdown menus and modal windows are the most common keyboard traps.
• Located in a high-filing jurisdiction. Businesses headquartered in New York, California, or Florida face the highest filing rates. These states account for over 75% of all ADA web accessibility lawsuits.

Anatomy of a Demand Letter

The first contact is usually a demand letter, not a lawsuit filing. The letter follows a predictable structure: it identifies the plaintiff (typically an individual with a disability who allegedly attempted to use your website), describes the specific barriers encountered (often generated by running an automated scan), cites the relevant ADA provisions, and offers to settle before litigation. The settlement demand typically ranges from $5,000 to $15,000 for a first contact, with the expectation of negotiation.

The letter will also demand that the website be remediated to comply with WCAG 2.1 Level AA within a specified timeframe, usually 90 to 120 days. This remediation requirement is separate from the financial settlement. Even if you settle the financial claim, you must still fix the website — and if you do not, a follow-up lawsuit becomes virtually guaranteed because the plaintiff firm already knows your site is non-compliant and has a documented history of your awareness of the issue.

Some demand letters are legitimate claims from individuals who genuinely attempted to use your website and encountered barriers. Others are generated by firms that run automated scans and file demand letters in bulk without any human actually visiting the site. From a legal perspective, both carry the same weight. The distinction between a "legitimate" claim and a "serial filer" claim does not change your obligation to make the website accessible or the financial risk of ignoring the letter.

The Serial Plaintiff Problem

Approximately 95% of ADA web accessibility lawsuits are filed by serial plaintiffs — individuals or firms that file dozens or hundreds of lawsuits per year. The top individual plaintiff in 2023 was named in over 300 federal lawsuits. These plaintiffs work with law firms on a contingency or fee-splitting basis, creating a financial incentive to maximize filing volume. The serial plaintiff model is controversial but has been repeatedly upheld by courts. The ADA permits private enforcement through lawsuits, and courts have ruled that the frequency of a plaintiff's filings does not invalidate their claims.

For business owners, the serial plaintiff dynamic creates a specific strategic consideration: fixing your website is the most cost-effective defense because the same automated tools that plaintiff firms use to find targets will stop flagging your site once the violations are remediated. Revenue Group's accessibility clients who achieve and maintain WCAG 2.1 AA compliance see their risk of receiving a demand letter drop to near zero because they no longer appear in the scans that drive the filing pipeline.

How to Reduce Your Lawsuit Risk to Near Zero

Proactive compliance is dramatically cheaper than reactive litigation. The average cost of remediating a small business website to WCAG 2.1 AA ranges from $3,000 to $12,000 depending on the site's size and complexity. The average cost of settling a single ADA lawsuit — including legal fees, settlement payment, and remediation — ranges from $13,000 to $55,000. The math is clear: compliance costs 25% to 50% of what a lawsuit costs, and it eliminates the risk entirely rather than resolving it one case at a time.

The five steps to reduce your risk:

1. Get an accessibility audit. A professional audit by a certified accessibility specialist identifies every WCAG violation on your site, prioritized by severity and legal risk. Revenue Group's audits cover automated scanning plus manual testing with screen readers and keyboard navigation, catching the 60% to 70% of issues that automated tools miss. For an overview of the audit process, see our website accessibility audit guide.
2. Remediate the high-risk violations first. Missing alt text, form label issues, keyboard navigation failures, and color contrast problems are the violations most commonly cited in lawsuits. Fix these first, then work through the remaining issues systematically.
3. Publish an accessibility statement. A public accessibility statement that describes your commitment to accessibility, the standard you are working toward (WCAG 2.1 AA), and a way for users to report issues demonstrates good faith. Courts view active remediation efforts and published commitments favorably.
4. Establish ongoing monitoring. Accessibility is not a one-time fix. Content updates, new features, third-party widget changes, and CMS updates can reintroduce violations. Monthly automated scans plus quarterly manual reviews maintain compliance over time.
5. Document everything. Keep records of your audit, remediation timeline, accessibility statement, and monitoring results. In the event of a demand letter, documented evidence of proactive compliance efforts significantly strengthens your negotiating position and may convince plaintiff firms to move on to easier targets.

What to Do If You Receive a Demand Letter

If a demand letter arrives, your response in the first 72 hours determines the trajectory of the case. The correct sequence: contact an attorney experienced in ADA litigation immediately (not your general business attorney — this is a specialized area), do not respond to the letter without legal counsel, begin a documented accessibility audit within 48 hours of receiving the letter, and do not install an accessibility overlay widget as a quick fix (overlays do not provide legal protection and may weaken your defense by suggesting you knew about the issue and chose an inadequate solution).

Your attorney will negotiate the financial settlement while you begin genuine remediation. Courts and plaintiff firms respond favorably to businesses that demonstrate active, good-faith compliance efforts. A documented timeline showing audit initiation, contractor engagement, and remediation milestones signals that you are taking the issue seriously and reduces the plaintiff's leverage. Revenue Group has supported multiple clients through this process, providing the technical remediation while the client's attorney handles the legal negotiation. The typical resolution timeline is 60 to 90 days from demand letter to settlement and completed remediation.
