How ADA Lawsuits Work: Standing, Filing, Damages, and Defenses

How ADA lawsuits work depends almost entirely on which of the statute’s three titles applies: Title I covers employment and runs through the EEOC with capped money damages, Title II covers state and local governments, and Title III covers private businesses open to the public and generally lets a court order the barrier fixed but not write you a check. Pick the wrong track and the case can be dismissed before a judge ever looks at the underlying discrimination.

Which Title Governs Your Situation

The three titles carry different defendants, different procedures, and different remedies.

Title I (employers): Private employers, state and local governments, employment agencies, and labor unions with 15 or more employees. It reaches hiring, firing, pay, promotion, job assignments, training, and every other employment practice.¹
Title II (government): Every state and local government entity regardless of size. Every program, service, and activity the government provides must be accessible.²
Title III (public accommodations): Private businesses that serve the public. This title generates the most accessibility litigation by volume.

“Public accommodations” is broader than most business owners assume. The statute lists 12 categories reaching hotels, restaurants, theaters, retail stores, shopping centers, banks, laundromats, gas stations, hospitals, private schools, daycare centers, gyms, museums, and parks.³ If a private business is open to the public, it is almost certainly covered.

Whether You Have Standing to Sue

Two things must be true before a federal court will hear the case.

First, you need a qualifying disability: a physical or mental impairment that substantially limits one or more major life activities, including walking, seeing, hearing, breathing, learning, concentrating, or working. The ADA Amendments Act of 2008 pushed courts to interpret that definition generously rather than gatekeeping who qualifies.⁴

Second, you need an “injury in fact.” That means you personally encountered the barrier or experienced the discrimination. Hearing about an inaccessible entrance from a friend, or spotting it in a Google Street View image, is not a concrete injury. Courts want evidence that you actually visited the location, tried to use the service, or were deterred from returning because you knew about the barrier. Documenting the date, the specific obstacle, and how it prevented access is what separates a viable claim from a hypothetical grievance.

A Note on Tester Plaintiffs

Federal appeals courts are split on whether “testers” — individuals who visit businesses or check websites specifically to identify violations, often with no intention of using the service — have Article III standing. Some circuits find standing on the theory that being denied legally required accessibility information is itself an injury. Others deny it when the plaintiff disclaims any intent to visit or use the facility. The Supreme Court had a chance to resolve the split in Acheson Hotels, LLC v. Laufer but dismissed the case as moot in December 2023. If you are on either side of a serial-plaintiff case, standing depends heavily on which federal circuit hears it.

What Counts as a Violation

Physical Barriers

The clearest ADA claims involve physical barriers measured against the 2010 ADA Standards for Accessible Design. The dimensions either pass or fail. Doorways must provide at least 32 inches of clear width. Ramps cannot exceed a 1:12 slope ratio. A portion of service counters must sit no higher than 36 inches above the floor.⁵ Parking spaces, restroom layouts, and clear floor space all carry similarly precise requirements. A building that was compliant when constructed in 1995 may violate current standards if renovations triggered an obligation to update.

Digital Accessibility

Websites and mobile apps have become a major source of ADA litigation. Screen-reader incompatibility, missing closed captions, and interfaces that cannot be navigated by keyboard alone effectively lock people with visual or auditory disabilities out of services other customers use freely. In April 2024, the Department of Justice published a final rule adopting WCAG 2.1 Level AA as the specific technical standard for state and local government websites and mobile apps under Title II.⁶ Title III has no formally codified web standard, but courts increasingly treat WCAG 2.1 Level AA as the benchmark for private business sites.

Workplace Discrimination

Under Title I, employers must provide reasonable accommodations to qualified employees with disabilities unless doing so would cause undue hardship.⁷ Accommodations might include a modified schedule, assistive software, restructured job duties, or adjusted training materials for an employee who is deaf or blind.

When an employee requests an accommodation, the employer is expected to engage in an informal “interactive process” to identify the need and available options. Skipping that conversation is one of the fastest ways for an employer to create liability. If an employer ignores the request or refuses to engage, the failure alone can support a claim, even when a workable accommodation existed that both sides could have agreed on. Discrimination also occurs when an employer applies qualification standards or screening criteria that disproportionately exclude people with disabilities without a legitimate business necessity.

Service Animals and Effective Communication

Turning away someone’s service animal remains one of the more common and easily avoidable violations. Under Titles II and III, service dogs must be permitted in all areas open to the public. When the animal’s purpose is not obvious, staff may ask only two questions: whether the dog is a service animal required because of a disability, and what task it has been trained to perform. Staff cannot ask about the disability, demand medical documentation, require certification, or ask for a demonstration.⁸

Public accommodations must also provide auxiliary aids so people with disabilities can communicate effectively. That might be a qualified sign language interpreter, real-time captioning, or written notes for someone who is deaf, or a qualified reader, large-print materials, or accessible electronic formats for someone who is blind. The business chooses the method, but the method must actually result in effective communication. A business cannot require the person to bring their own interpreter, and relying on a minor child to interpret is prohibited outside genuine emergencies.⁹

What You Can Recover

What you can win depends almost entirely on which title applies. Plaintiffs regularly expect a damage award and learn too late that their claim is limited to a court order.

Title III: Injunctive Relief Only

In a private Title III suit, the primary remedy is injunctive relief: a court order requiring the business to install a ramp, widen a doorway, lower a counter, or make a website screen-reader compatible. Federal law does not allow individual plaintiffs to recover compensatory or punitive damages in private Title III suits.¹⁰ The court can award reasonable attorney’s fees and litigation costs to the prevailing party.¹¹

The absence of direct monetary relief for individual Title III plaintiffs is a deliberate design choice. Congress focused Title III enforcement on fixing barriers rather than generating payouts. When the Department of Justice itself brings a Title III action, it can seek civil penalties adjusted for inflation and monetary damages on behalf of aggrieved individuals.

Title I: Damages With Statutory Caps

Employment claims under Title I incorporate the remedies available under the Civil Rights Act of 1991. A prevailing plaintiff can recover compensatory damages for emotional distress and other noneconomic harm, plus punitive damages if the employer acted with malice or reckless indifference. The combined total of compensatory and punitive damages is capped by employer size:¹²

15 to 100 employees: $50,000
101 to 200 employees: $100,000
201 to 500 employees: $200,000
More than 500 employees: $300,000

The caps apply per complaining party and cover only compensatory and punitive damages. Back pay and front pay are not subject to these limits. An employer that engaged in a good-faith interactive process may also gain protection from punitive damages, which is one more reason the interactive process matters strategically for both sides.

State Law Claims

Because federal Title III does not pay individuals directly, many plaintiffs file parallel claims under state civil rights or accessibility statutes that offer broader financial remedies. Several states authorize statutory minimum damages per violation, and some allow recovery for emotional distress. Pairing a federal ADA claim with a state-law claim lets a plaintiff seek both the court-ordered fix and a damage award. Availability and amounts vary significantly by state.

How and When to File

Employment Claims: The EEOC Path

Before filing a Title I lawsuit, you must file a charge of discrimination with the Equal Employment Opportunity Commission. The deadline is strict: generally 180 days from the discriminatory act, extended to 300 days if a state or local agency also enforces anti-discrimination laws covering the same conduct.¹³ Missing this window forfeits the claim regardless of how strong the evidence is.

The charge must identify the employer and describe the discriminatory act, including specific dates and the harm. The EEOC then investigates. After 180 days from the date the charge was filed, you can request a “right to sue” letter authorizing you to proceed in federal court. Once that letter arrives, you have 90 days to file the lawsuit.¹⁴ Without it, the court will dismiss for failure to exhaust administrative remedies. The ADA borrows Title VII’s procedural framework for this whole sequence.¹⁵

Title II and Title III: File Directly

Claims against state and local governments under Title II and claims against businesses under Title III do not require EEOC exhaustion. DOJ regulations expressly allow Title II plaintiffs to file a private lawsuit at any time, whether or not an administrative complaint has been filed or resolved.¹⁶ Title III likewise allows private suits without prior administrative steps. Federal law does not require a plaintiff to send a pre-suit notice before filing a Title III case, though some states have enacted their own notice requirements.

Statute of Limitations

The ADA itself contains no statute of limitations for Title II or Title III claims. Federal courts borrow the most analogous limitations period from the state where the lawsuit is filed, typically the state’s statute of limitations for personal injury claims.¹⁷ Depending on the state, that can range from one to six years, and identifying the correct period requires checking local law. For ongoing violations like a permanently inaccessible entrance, the clock may reset each time the plaintiff encounters the barrier, but courts are not uniform on this point.

Defenses the Other Side Can Raise

The ADA does not require the impossible or the ruinous. Several defenses let businesses and employers push back when compliance would be unreasonably burdensome or physically impractical.

Readily Achievable Barrier Removal

Existing businesses that were not built to current accessibility standards must remove barriers only where doing so is “readily achievable,” defined as easily accomplishable without much difficulty or expense. The statute identifies four factors: the cost of the modification, the financial resources of the specific facility, the overall resources and size of the parent entity, and the nature of the business’s operations.³ A national hotel chain will have a much harder time arguing that a ramp is too expensive than a single-location restaurant with five employees. If full compliance is not readily achievable, the business must still make access improvements to the maximum extent feasible.

Undue Hardship

In Title I cases, an employer can decline a requested accommodation by showing it would cause “undue hardship,” meaning significant difficulty or expense. Courts weigh the accommodation’s cost, the facility’s financial resources and number of employees, and the impact on operations. The analysis is individualized. An employer cannot rely on generalized cost assumptions, the prejudices of coworkers, or a cost-benefit calculation weighing the accommodation against the employee’s perceived productivity. Outside funding sources like state vocational rehabilitation agencies and available tax credits count against the price tag, so the net cost to the employer is what matters.⁷

Technical Infeasibility

When a business renovates an existing building, altered areas must meet current accessibility standards. Sometimes structural conditions make full compliance physically impossible without removing load-bearing walls or confronting other site constraints. In those cases, the alteration must still comply to the maximum extent feasible. If a space cannot be made accessible to wheelchair users, the business must still make it accessible to people with other disabilities, such as those who use crutches or who have impaired vision or hearing.¹⁸
