Federal Title III of the Americans with Disabilities Act is not the only accessibility law that matters for your website. State laws run alongside it. Some state laws allow private money damages where federal law does not. Some state laws apply to businesses that federal law might not reach.
This article walks through the federal baseline and the state laws most likely to be cited in demand letters and filings.
Federal Title III in one paragraph
Title III of the ADA prohibits discrimination on the basis of disability in "places of public accommodation." The Department of Justice and private plaintiffs enforce it. Private plaintiffs can obtain injunctive relief, meaning a court order requiring remediation, and attorney fees. Title III does not authorize monetary damages for private plaintiffs. The damages in most settled cases come from state law claims paired with the federal action, or from the plaintiff's demand for a nuisance-value settlement to avoid litigation costs.
The key federal question for websites has been whether a website is a "place of public accommodation" under Title III. Courts have split. Most appellate courts have held that websites operated by businesses with physical storefronts are covered. The Ninth Circuit has held that purely online businesses may be covered. The Eleventh Circuit has been more restrictive. Congress has not resolved the split legislatively. The Department of Justice has adopted regulations for state and local government websites under Title II, but has not issued a Title III regulation mandating WCAG conformance for private businesses.
The practical consequence. Title III is interpreted by case law, which varies by circuit, and WCAG 2.1 AA is the de facto standard most plaintiffs cite regardless of whether a regulation requires it.
California: Unruh Civil Rights Act
California's Unruh Civil Rights Act is the single most consequential state accessibility law for private businesses.
Unruh ties to Title III. Any violation of the ADA is a violation of Unruh by statutory reference. Unruh authorizes minimum statutory damages of four thousand dollars per violation, plus attorney fees. A single visit to an inaccessible website can generate a separate violation for each barrier encountered. A complaint may allege multiple violations per visit and multiple visits.
The result. California generates more ADA website lawsuits per capita than any state except possibly New York. Plaintiff's firms file in California state court or in federal court with supplemental state-law claims.
Mitigation for a business with California customers. File a California accessibility statement on the site. Monitor and respond to California-based feedback reports promptly. Keep your remediation log current. An Unruh claim without a specific plaintiff attempt is weaker; your feedback-channel responsiveness matters.
New York: State Human Rights Law and City Human Rights Law
New York State Human Rights Law and New York City Human Rights Law both cover public accommodations and both have been applied to websites.
The NYCHRL is particularly aggressive. It is interpreted liberally by courts and allows compensatory damages, punitive damages in some circumstances, and attorney fees. Its coverage of public accommodations is broader than federal Title III.
The Southern District of New York is the highest-volume federal venue for ADA website cases. A significant fraction of those cases also plead NYSHRL or NYCHRL claims in addition to federal Title III.
Mitigation. Same elements as California. Accessibility statement, remediation log, responsive feedback channel. The NYCHRL is not easily defeated on procedural grounds, which makes substantive compliance the primary defense.
Florida: state law, federal venue
Florida does not have a general-purpose state accessibility law that adds damages in the way California's Unruh does. But the Southern District of Florida is the third-highest federal filing venue for Title III cases. The appeal of Florida as a filing venue comes from both the concentration of tourist-economy businesses and the Eleventh Circuit's evolving precedent.
Small businesses outside Florida with Florida customers should be aware that a Florida filing is possible if the site conducts business with Florida residents.
Colorado: HB 21-1110 and public entities
Colorado's House Bill 21-1110, signed in 2021 and with enforcement provisions that phased in through 2024 and 2025, imposes accessibility requirements on state and local government entities. The law requires conformance with specific standards, establishes damages, and creates a private right of action.
The direct effect on private businesses is limited, because HB 21-1110 covers public entities. The indirect effect is significant. Contractors and vendors supplying public entities in Colorado now face contractual requirements that their products meet the same standards. A SaaS vendor selling to a Colorado school district is expected to conform to WCAG 2.1 AA under the contract.
Expect other states to pass similar laws. Proposed legislation tracking similar models has appeared in Illinois, Washington, and Massachusetts in recent sessions.
Minnesota, Massachusetts, and other general-purpose state laws
Several states have general-purpose disability rights statutes that apply to public accommodations and have been extended to websites by some courts. Minnesota's Human Rights Act. Massachusetts's 93A consumer protection statute in combination with its disability rights provisions. New Jersey's Law Against Discrimination.
The legal environment varies by state. An SMB with national customers has exposure in the most aggressive states, which in most analyses are California, New York, and Massachusetts.
Section 508 and private businesses
Section 508 of the Rehabilitation Act applies to federal agencies and federal contractors. It is frequently cited in accessibility discussions but does not generally apply to private businesses without federal contracts.
If you are a federal contractor or subcontractor, Section 508 conformance may be a contractual requirement. Section 508 uses a technical standard called the Revised 508 Standards, which is harmonized with WCAG 2.0 AA and is close to but not identical with WCAG 2.1 AA.
If you are not a federal contractor, Section 508 is a reference point, not a legal obligation. Demand letters that cite Section 508 against a private business without a federal contract are often citing it as a standard rather than as a governing statute.
How this affects response strategy
Three implications for a business that receives a demand letter or claim.
Check which laws are actually cited. A demand letter citing only Title III is a less aggressive posture than one citing Title III plus Unruh. The paired state claims are where private damages are generated. If your letter names the state claim, the plaintiff is sophisticated and the settlement floor is higher.
Check your customer geography. If you have no California customers and no California business activities, an Unruh claim may face a standing hurdle. If you have meaningful California activity, the claim is substantive regardless of where you are headquartered.
Do not treat federal compliance as sufficient. Federal Title III sets the floor. State laws can raise the ceiling. A small business with California customers who assumes federal compliance covers them is wrong.
The simple version
Title III is the federal baseline. Injunctive relief. No private damages. Attorney fees.
California Unruh, New York NYCHRL, and a growing list of other state laws add monetary damages on top of federal claims.
Federal Section 508 is a standard, not a law, for most private businesses.
