Americans with Disabilities Act Regulations: Titles and Enforcement

The regulations under the Americans with Disabilities Act are a set of federal rules that spell out how the 1990 civil rights law is applied in five distinct areas: employment, state and local government services, businesses open to the public, telecommunications, and a group of cross-cutting protections like anti-retaliation. Each area has its own regulations, its own enforcing agency, and its own procedures for filing a complaint. Knowing which title of the ADA governs your situation is the first step in knowing what the law actually requires.¹

The Five Titles and Who Enforces Them

The ADA is organized into five titles. Each targets a different part of daily life and is enforced by a different federal body.¹²

Title I covers employment at private employers, state and local governments, employment agencies, and unions with 15 or more employees. The Equal Employment Opportunity Commission enforces it.
Title II covers all services, programs, and activities of state and local governments, from public schools and courts to sidewalks and government websites. The Department of Justice is the lead enforcer, with the Federal Transit Administration handling public transit.
Title III covers private businesses and nonprofits open to the public, plus commercial facilities like offices and factories. The DOJ enforces it, and private plaintiffs can sue directly.
Title IV requires telephone companies to provide relay services for people who are deaf, hard of hearing, or have speech disabilities. The Federal Communications Commission enforces it.
Title V contains cross-cutting rules, including anti-retaliation protections, attorney’s fee provisions, and authority for agencies to issue guidance.

Who Qualifies as a Person With a Disability

Under the regulations, a person has a disability if they meet any one of three tests: they have a physical or mental impairment that substantially limits one or more major life activities; they have a record of such an impairment, like cancer in remission; or they are regarded by others as having such an impairment even if they do not.¹

Major life activities include walking, seeing, hearing, breathing, eating, sleeping, speaking, thinking, concentrating, reading, learning, communicating, and working. They also include the operation of major bodily functions such as the immune, digestive, circulatory, endocrine, and reproductive systems, and normal cell growth.³

The threshold for “substantially limits” is deliberately broad. An impairment does not have to prevent or severely restrict an activity; it only has to meaningfully limit one. Courts are told not to demand extensive medical analysis. A mild seasonal allergy would typically fall short.¹

This broad standard exists because Congress corrected the courts. The ADA Amendments Act of 2008 (ADAAA) rejected two Supreme Court decisions — Sutton v. United Air Lines (1999) and Toyota Motor Manufacturing v. Williams (2002) — that had narrowed the definition so tightly that people with cancer, diabetes, and epilepsy were being denied protection.⁴ Under the ADAAA, disability determinations are made without considering the benefits of mitigating measures like medication, hearing aids, or prosthetics. Ordinary eyeglasses and contact lenses are the sole exception. Conditions that are episodic or in remission still qualify if they would substantially limit a major life activity when active.³ The DOJ updated its Title II and Title III regulations to match, and the EEOC revised its Title I regulations in 2011.⁵

Title I Employment Rules

Title I regulations require employers with 15 or more employees to give qualified individuals with disabilities equal opportunity in every aspect of employment: recruitment, hiring, pay, promotions, job assignments, training, benefits, layoffs, and firing.⁶ The regulations also prohibit retaliation and discrimination based on someone’s association with a person who has a disability.

Reasonable Accommodation and the Interactive Process

The core Title I obligation is providing reasonable accommodations — changes to the work environment or to how a job is performed that let a qualified worker with a disability participate on equal footing. Common examples include modified schedules, job restructuring, assistive equipment, reassignment to a vacant position, accessible facilities, or providing readers or sign language interpreters.⁷

Once you ask for an accommodation, the employer is expected to enter what the EEOC calls the “interactive process”: an informal back-and-forth to identify the limitation and figure out what would work. You do not need to use legal terminology. Something like “I have a medical condition and need a change at work” is enough to start it.⁸ If the disability or need for accommodation is not obvious, the employer can ask for supporting documentation from a healthcare provider, but cannot demand unrelated medical records.⁷

Employers do not have to eliminate essential job functions, create new positions, or lower production standards. They can pick among effective accommodations, including the cheapest one, as long as it actually works. Unreasonable delays in the interactive process or in delivering an accommodation can themselves be violations.⁷

Undue Hardship

An employer can refuse a specific accommodation only if it would cause “undue hardship” — significant difficulty or expense measured against the employer’s resources and circumstances. The analysis is case-by-case, weighing the cost, the employer’s size and finances, and the nature of the business. Even if one accommodation is too burdensome, the employer still has to look at alternatives.⁶

Filing a Charge With the EEOC

To pursue a Title I claim, you file a charge with the EEOC within 180 days of the discriminatory act, or within 300 days if a state or local agency also bans disability discrimination.⁹ The EEOC notifies the employer within 10 days and may offer mediation, which typically wraps in under three months. Investigations average about 10 months. If the agency finds reasonable cause, it tries to settle. Failing that, it may sue on your behalf or issue a Notice of Right to Sue, giving you 90 days to file your own federal case.¹⁰ Remedies include hiring, reinstatement, back pay, promotion, reasonable accommodation, and attorney’s fees.⁶

Title II Rules for State and Local Government

Title II regulations require state and local governments to make every service, program, and activity accessible to people with disabilities. That reaches public education, voting, transit, healthcare programs, courts, prisons, parks, and sidewalks. The core duties are effective communication (so people with disabilities can access the same information as everyone else), reasonable modifications to policies and procedures, and equal opportunity to participate in and benefit from government services.¹¹

The 2024 Web Accessibility Rule

In April 2024, the DOJ published the first federal regulation setting specific technical standards for government websites and mobile apps. Public entities must make web content and mobile apps comply with the Web Content Accessibility Guidelines (WCAG) Version 2.1, Level AA, which addresses screen reader compatibility, text alternatives for images, keyboard navigation, and color contrast, among other issues.¹¹

The rule covers everything a government provides or makes available online, including content delivered by third-party contractors. It carves out limited exceptions for archived content, pre-existing documents not currently used to access services, unaffiliated third-party content like user comments, individualized password-protected documents, and social media posts from before the compliance deadline.¹² Entities do not have to take actions that would fundamentally alter their services or impose undue financial burdens, and minor nonconformance that does not actually block access is not a violation.¹³

The original deadlines were April 24, 2026, for entities serving 50,000 or more people, and April 26, 2027, for smaller entities and special district governments.¹¹ On April 20, 2026, the DOJ issued an interim final rule pushing both deadlines back by one year, to April 26, 2027, and April 26, 2028, respectively.¹⁴ The DOJ cited resource constraints, staffing shortages, and technical challenges raised by educational institutions and the Small Business Administration, and said it might issue new proposed rulemaking reconsidering parts of the 2024 rule.¹⁵

In May 2026 the National Federation of the Blind sued the DOJ over the delay in a case known as NFB v. DOJ. The organization alleges the DOJ violated the Administrative Procedure Act by extending the deadlines without proper notice-and-comment rulemaking and without adequately considering the harm to people with disabilities. The suit asks the court to block the delay and restore the original deadlines.¹⁶

Title III Rules for Businesses Open to the Public

Title III regulations apply to what the law calls “places of public accommodation”: restaurants, hotels, retail stores, movie theaters, private schools, doctors’ offices, gyms, day care centers, and privately operated transit, among others. Religious organizations and certain bona fide private clubs are exempt.¹⁷¹⁸

Covered businesses must give people with disabilities an equal opportunity to access their goods and services. They must modify policies, practices, and procedures when necessary (unless that would fundamentally alter what they offer) and ensure that communication is as effective for people with disabilities as for anyone else. That may mean providing auxiliary aids like sign language interpreters, large-print materials, or accessible technology.¹⁷

Physical Design Standards

The 2010 ADA Standards for Accessible Design are the enforceable design rules. Published by the DOJ on September 15, 2010, and mandatory for new construction and alterations since March 15, 2012, they set detailed scoping and technical specifications for accessible routes, ramps, curb ramps, parking, restrooms, doors, signage, dining surfaces, and dressing rooms, among other elements.¹⁹

For existing buildings, the rule is softer. Businesses have to remove architectural barriers when doing so is “readily achievable,” meaning it can be done without much difficulty or expense given the business’s size and resources.¹⁷ When a building is altered, the altered area has to meet the 2010 Standards. If the alteration affects an area containing a primary function like a dining room or office, the path of travel to that area, including restrooms, drinking fountains, and telephones, must also be made accessible, unless the added cost would exceed 20% of the overall alteration cost.²⁰ A “safe harbor” protects elements built in compliance with the earlier 1991 Standards from having to meet the 2010 Standards just because of a later nearby alteration.¹⁹

New construction faces the strictest rule. Any facility built for first occupancy after January 26, 1993, must be readily accessible, with a waiver available only in rare cases where the terrain makes accessibility structurally impracticable. Buildings under three stories or with less than 3,000 square feet per floor are generally exempt from having to install an elevator, unless they contain a shopping center, healthcare provider’s office, or transit terminal.²¹

Websites Under Title III

Title III has no specific web accessibility regulation. The DOJ issued general web accessibility guidance for private businesses in 2022 but set no technical requirements, and as of 2026 there is no expectation that Title III web accessibility regulations will be issued in the near term.²²

The absence of a regulation has not slowed litigation. Roughly 2,500 federal website accessibility lawsuits were filed under Title III in 2024, and more than 5,000 in 2025.²²²³ Most settle. About a quarter of 2024 suits targeted businesses using accessibility “widgets” or “overlays,” third-party tools marketed as quick fixes that plaintiffs argue do not achieve real compliance.

Federal courts are split on whether Title III covers online-only businesses with no physical location. The First, Second, and Seventh Circuits read the statute broadly enough to cover nonphysical “places” of public accommodation. The Ninth Circuit requires a nexus between the website and a physical location. The Eleventh Circuit took an even narrower position in Gil v. Winn-Dixie Stores (2021), holding that websites themselves are not places of public accommodation.²⁴²⁵ H.R. 3417, the bipartisan Websites and Software Applications Accessibility Act introduced in May 2025, would resolve the split by affirming federal coverage of digital spaces regardless of physical connection and directing the DOJ and EEOC to develop enforceable rules. The bill remains in committee.²⁶

How Title III Is Enforced

The DOJ enforces Title III through public complaints. It screens them for jurisdiction, may refer to mediation, and can investigate directly. When an investigation finds a violation, the DOJ seeks a voluntary compliance agreement that can include structural modifications, policy changes, staff training, civil penalties, and periodic reporting. When negotiation fails, the DOJ can sue.²⁷

Private individuals can also sue under Title III, but the remedies are narrower than under Title I. Private plaintiffs generally cannot recover compensatory damages. They can get court orders requiring the business to become accessible and can recover attorney’s fees. Some states add remedies of their own; California allows private plaintiffs to recover $4,000 per violation under state law.²⁷

Title IV Telecommunications Relay

Title IV requires the FCC to ensure that telecommunications relay services (TRS) are available nationwide so people who are deaf, hard of hearing, deafblind, or have speech disabilities can make and receive phone calls in a way that is “functionally equivalent” to standard voice service. Relay must be available 24 hours a day, every day, and users cannot be charged more than the rate for equivalent voice calls. Relay operators cannot refuse calls, limit their length, disclose their content, or alter what is said.²⁸ Services have grown well beyond text telephone relay to include Video Relay Service, IP Captioned Telephone, IP Relay, Speech-to-Speech, and Captioned Telephone, all provided at no cost to users and funded through a TRS Fund supported by interstate telecommunications subscribers.²⁹ The nationwide abbreviated dialing code for relay is 711.³⁰

Service Animal Rules

The DOJ’s service animal regulations run through Titles II and III and are among the most-encountered ADA rules in day-to-day life. A service animal is a dog individually trained to do work or perform tasks for a person with a disability. Dogs whose only role is to provide emotional comfort or support do not qualify.³¹

Businesses and government entities must allow service animals wherever the public can go, with narrow exceptions like sterile operating rooms. They cannot charge extra fees or deposits, even where they normally charge a pet fee. If it is not obvious what the dog does, 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 nature of the disability, demand documentation, or require the dog to demonstrate its task.³¹

A service animal can be removed only if it is out of control and the handler does not correct it, or if it is not housebroken. Allergies and fear of dogs are not valid grounds for denying access. Miniature horses trained to perform tasks must also be accommodated through reasonable modifications, though businesses can weigh factors like facility size and safety.³¹

Retaliation and Interference

Title V makes it unlawful to retaliate against anyone who files a disability discrimination complaint, participates in an investigation, requests a reasonable accommodation, or otherwise opposes conduct they reasonably believe violates the ADA. These protections apply across every title of the law and reach people who do not themselves have a disability.³²

Retaliation includes any action that would discourage a reasonable person from making or supporting a complaint: reprimands, negative evaluations, transfers to less desirable positions, increased scrutiny, or verbal abuse, among other things.³³ The ADA also bans coercion, intimidation, threats, and interference with someone exercising their rights, even if the threat is never carried out. Remedies include back pay, front pay, reinstatement, and compensatory and punitive damages.³²

What the ADA Does Not Cover

Several categories fall outside the ADA. The federal government is not covered; its disability obligations come from the Rehabilitation Act of 1973. Religious organizations, including places of worship and entities they control, are broadly exempt from Title III even when they run activities like schools that would otherwise be public accommodations. Bona fide private clubs that meet the criteria under the Civil Rights Act of 1964 are also exempt, though they lose the exemption when they open their facilities to non-members.¹⁸

Multifamily housing is covered by the Fair Housing Act rather than the ADA, although places of public accommodation inside residential complexes, like a rental office or a publicly accessible pool, still fall under Title III. Air transportation is covered by the Air Carrier Access Act, not the ADA, though private air terminals remain subject to ADA construction requirements.¹⁸

Recent Changes to the Regulations

ADA regulations have been a point of policy tension in 2025 and 2026. Executive Order 14192 imposed a regulatory cap requiring that the total incremental cost of new regulations be “significantly less than zero,” with any new regulatory cost offset by eliminating costs from at least 10 existing regulations. In September 2025 the DOJ announced it would not pursue 54 pending regulatory actions, including two ADA rulemakings: one addressing accessible equipment and furniture in public accommodations and government facilities, and another addressing accessible routes in public areas under state and local government jurisdiction.³⁴

At the state level, Missouri enacted the Act Against Abusive Website or Web Content Access Litigation, signed on May 6, 2026, with an effective date of August 28, 2026. The law gives defendants a 90-day window to correct alleged accessibility issues before a suit can proceed, and creates a rebuttable presumption that later claims are abusive if the defendant makes good-faith remediation efforts during that window. Courts can award attorney’s fees and punitive damages against plaintiffs found to be engaging in abusive litigation. The law does not override federal ADA obligations, and plaintiffs can still proceed if they believe violations are serious or remediation is insufficient.³⁵
