The reason ADA website lawsuits in Illinois exploded — from roughly 93 federal filings in 2024 to about 585 in 2025, third-highest in the nation — is the Seventh Circuit’s broad reading of the ADA: a website can be a public accommodation on its own, with no physical store required. That makes Illinois federal court an inviting venue for plaintiffs.

Illinois’s distinct angle: the Seventh Circuit needs no physical store

Most website-accessibility risk comes down to one legal question: can a website by itself be a “place of public accommodation” under Title III of the ADA, or does it only count when it’s tied to a brick-and-mortar location? The federal circuits are split, and Illinois sits on the plaintiff-friendly side of that split.

The Seventh Circuit Court of Appeals — whose precedent binds the federal district courts in Illinois — described public accommodations broadly in Doe v. Mutual of Omaha Insurance Co., 179 F.3d 557 (7th Cir. 1999). Writing for the court, Judge Posner framed the operator of “a store, hotel, restaurant, dentist’s office, travel agency, theater, Web site, or other facility (whether in physical space or in electronic space) … that is open to the public” as unable to exclude disabled persons (FindLaw — Doe v. Mutual of Omaha). The Seventh Circuit reinforced that reasoning in Morgan v. Joint Administrative Board, 268 F.3d 456 (7th Cir. 2001), where Judge Posner wrote that “an insurance company can no more refuse to sell a policy to a disabled person over the Internet than a furniture store can refuse to sell furniture to a disabled person who enters the store. The site of the sale is irrelevant” (FindLaw — Morgan v. Joint Admin. Bd.).

That matters enormously. Courts that take the narrower view generally require a website to have a nexus — a connection to a physical place of business — before the ADA applies; the Ninth Circuit’s Robles v. Domino’s line is the best-known example. Illinois has no such requirement. As one practitioner overview summarizes, the First, Second, and Seventh Circuits treat a website as a public accommodation independent of any physical location, while the Third, Fifth, Sixth, Ninth, and Eleventh read the statute more narrowly (Understanding the ADA). In plain terms: a purely online-only Illinois business with no storefront is still a realistic defendant here. In California — see our California ADA lawsuit guide — that same business often isn’t.

The numbers: why Illinois jumped to third nationally

Illinois did not drift up the rankings — it leapt. According to Seyfarth’s annual tally of federal court website accessibility filings, plaintiffs filed 3,117 such suits nationally in 2025, a 27% increase over 2024. Within that total, Illinois recorded about 585 filings — third in the country, behind New York (1,021) and Florida (961), and ahead of states like Minnesota and Pennsylvania that previously outranked it (Seyfarth ADA Title III).

That is a roughly six-fold year-over-year climb from Illinois’s ~93 filings in 2024. The driver isn’t a sudden wave of new disabilities — it’s lawyer behavior. Seyfarth attributes the 2025 national jump in part to new plaintiffs’ attorneys entering the website space, and the Northern District of Illinois (Chicago) is a logical landing spot precisely because the Seventh Circuit’s electronic-space language lowers the early-motion hurdle for plaintiffs.

Illinois state law: the IITAA and the Human Rights Act

Two Illinois statutes matter, and it’s important not to conflate them with the federal ADA.

The Illinois Information Technology Accessibility Act (IITAA) sets the state’s accessibility bar — but only for government. The current IITAA 2.1 Standards require conformance with WCAG 2.1 Level AA and took effect June 24, 2024, applying to Illinois executive, legislative, and judicial agencies, constitutional offices, and public universities (Illinois Department of Innovation & Technology). It does not cover private businesses, local governments, school districts, or community colleges, and it’s enforced administratively through DoIT rather than by private lawsuit. Its real significance for a business is signaling: when the state itself codifies WCAG 2.1 AA, that’s the standard a court is least likely to second-guess.

The Illinois Human Rights Act (IHRA) is the state’s anti-discrimination law and reaches “places of public accommodation.” Illinois amended the Act in 2007 to broaden what qualifies after court rulings narrowed it, and the state has positioned the IHRA as offering protections that can exceed the federal ADA (Illinois Department of Human Rights). As of January 1, 2025, the window to file a charge with the Illinois Department of Human Rights expanded to two years (Illinois DHR). The practical upshot: an Illinois business can face a federal ADA claim and a parallel state-law theory, so remediating to one standard — WCAG 2.1 AA — is what closes both doors.

Who is getting sued in Illinois

The Illinois surge is the product of a few firms filing in volume in one courthouse — the Northern District of Illinois in Chicago — not of disabled Illinoisans suddenly encountering more broken sites. The mid-year data makes that concrete: Illinois filings soared from 28 in the first half of 2024 to 237 in the first half of 2025 — a 745% jump that moved the state into the top tier of venues (EcomBack 2025 mid-year report). Nationally, a handful of plaintiffs’ firms drive most volume — Manning Law, Gottlieb & Associates, and Equal Access Law Group each filed in the hundreds — and Illinois is now one of the courthouses where that volume lands, precisely because Doe and Morgan lower the early-motion hurdle for plaintiffs (UsableNet lawsuit tracker). For the repeat filers behind the numbers, see our breakdown of serial ADA plaintiffs.

Two features of the Illinois docket set it apart from nexus states:

  • Online-only brands are fully in scope. In a circuit that demands a physical nexus, a web-only retailer can argue it isn’t a “place” at all. In the Seventh Circuit, Doe’s “electronic space” language forecloses that defense, so Illinois complaints routinely name pure-play ecommerce and direct-to-consumer sites with no Illinois storefront.
  • Small and mid-size Illinois businesses, not just nationals. Because filing in the Northern District is cheap and the legal posture is favorable, plaintiffs’ firms target modest restaurant, hotel, and local-services sites — often built on Shopify or WordPress, where the same theme-level barriers recur across many defendants.

The barriers cited track WCAG 2.1 AA and the DOJ’s own guidance (ADA.gov on web accessibility): images without alt text, forms a screen reader can’t complete, insufficient color contrast, content unreachable by keyboard navigation, and broken focus states. Under Title III a plaintiff doesn’t have to prove monetary harm — only that the site presented a barrier to access.

How an Illinois business reduces exposure

The Seventh Circuit’s posture changes which defenses are even available. In a nexus state, a web-only defendant can move to dismiss on the threshold question of whether a website is a “place” at all. After Doe and Morgan, that motion loses in Illinois — so the realistic levers here are an accessible site, plus the narrower procedural arguments (standing, mootness once the site is fixed) that counsel can raise. That makes actually remediating the code, not arguing jurisdiction, the load-bearing move.

  1. Audit against the standard the DOJ and Illinois both cite. Federal courts and the DOJ point to WCAG 2.1 Level AA (ADA.gov web guidance; W3C/WAI), and Illinois codified that same bar for public bodies under the IITAA 2.1 Standards. Start with a manual accessibility audit that pairs automated scanning with keyboard and screen-reader testing — automated tools alone catch only a fraction of the failures Illinois complaints recite.
  2. Remediate the actual code. Because the “it’s not a place” defense is foreclosed in the Seventh Circuit, a genuinely usable site is your strongest position. Curbcut’s manual remediation fixes the HTML, ARIA, contrast, and focus management by hand, file by file, so the barriers are gone rather than masked.
  3. Document with both Illinois filing windows in mind. A dated accessibility statement and remediation log matter more here because an Illinois business can be sued on two clocks — a federal Title III complaint and a separate Illinois Human Rights Act charge with a two-year filing window since January 1, 2025 (see below). Good-faith records help moot a federal claim once fixes ship and rebut a parallel state charge.
  4. Monitor. A new product page, untagged PDF, or third-party booking widget can reintroduce barriers overnight — and because a fixed-then-rebroken site can revive a mootness-dismissed claim, ongoing accessibility monitoring is genuinely defensive here, not just hygiene.

A word of warning specific to the litigation reality here: accessibility overlays do not protect you. They paint over source code at runtime, screen-reader users frequently report they make sites harder to use, and overlay vendors themselves have been named in suits (UsableNet on overlay litigation). Read why overlays don’t work and overlay vs. manual remediation before you trust one in a Seventh Circuit venue, where there is no jurisdictional fallback if the overlay fails.

The bottom line for Illinois

Illinois is a top-three filing state because the Seventh Circuit already answered the question every other defense turns on: a website is a public accommodation in its own “electronic space,” with no storefront required. Doe and Morgan mean an Illinois defendant cannot dismiss its way out on the threshold “it’s not a place” argument — and a parallel Illinois Human Rights Act charge now runs on a two-year clock. The defense that actually works in this circuit is a site that passes WCAG 2.1 AA when someone tests it. Start with a free accessibility scan, then have Curbcut audit and remediate the code by hand — so your site holds up in a Chicago courtroom where the easy jurisdictional escape hatch is already closed.
