IllinoisWeb Accessibility Laws & ADA Compliance
Illinois is home to roughly 12.5 million people, and about 10.9% of them live with a disability. That is an estimated 1,363,000 residents who depend on accessible websites to shop, bank, book appointments, and reach essential services. For businesses, Illinois is a moderate-risk state for ADA web accessibility litigation, with approximately 123 web accessibility lawsuits filed each year. Beyond federal ADA Title III, the Illinois Human Rights Act adds a distinct layer of state-level exposure.
Federal and Illinois Requirements
Federal ADA Title III
At the federal level, ADA Title III requires that places of public accommodation be accessible to people with disabilities. Federal courts have consistently interpreted this to cover business websites, and the Department of Justice references the Web Content Accessibility Guidelines (WCAG) as the technical benchmark for conformance. This obligation applies to businesses in Illinois regardless of any state law.
Illinois Human Rights Act
Illinois enforces the Illinois Human Rights Act. Prohibits disability discrimination in public accommodations. The Illinois Attorney General has authority to bring enforcement actions. For businesses operating in Illinois, this means compliance requires attention to both federal ADA requirements and this state statute.

How to Reduce Accessibility Risk in Illinois
Illinois is a moderate-risk state for web accessibility litigation, so the practical goal is the same one the courts and the DOJ point to: conformance with WCAG 2.2 Level AA. These steps move a site toward that standard.
- 1
Scan for machine-detectable issues
Run an automated accessibility scan to surface missing alt text, low color contrast, unlabeled form fields, and ARIA misuse. This catches roughly 30 to 40% of WCAG failures and gives you a prioritized starting point.
- 2
Fix critical and serious violations first
Prioritize issues that block core tasks such as navigation, forms, checkout, and account access. These are the barriers most often cited in demand letters and the ones that most affect real users.
- 3
Test with a keyboard and a screen reader
Automated tools cannot judge whether a page is genuinely usable. Manual testing with keyboard-only navigation and a screen reader closes the gap on the remaining WCAG criteria that scans cannot evaluate.
- 4
Publish an accessibility statement and re-test regularly
Document your conformance target and remediation process, then re-scan after every significant site change. In Illinois's moderate-risk climate, ongoing monitoring is what keeps a fixed site from regressing.
