What Is ADA Compliance? Rules, Accommodations, and Penalties

ADA compliance means meeting the requirements of the Americans with Disabilities Act, the 1990 federal civil rights law that prohibits discrimination against people with disabilities in employment, state and local government services, and businesses open to the public. What you actually have to do depends on which part of the law covers you: employers, public agencies, and private businesses each face a different set of obligations, and violations now carry civil penalties above $118,000 for a first offense.

Who Has to Comply

The ADA splits its rules across three main titles, and the first step in compliance is figuring out which one applies to you.

Title I: Employers

Private employers with 15 or more employees have to follow Title I. The threshold counts full-time, part-time, and seasonal workers across 20 or more calendar weeks in the current or preceding year.¹ State and local government employers are covered under Title I regardless of size.²

Title II: State and Local Governments

Every state and local government entity is covered, along with its departments and agencies. Public schools, libraries, courthouses, parks departments, transit systems, and municipal offices all have to keep their programs and services accessible.³ There is no size threshold. A small-town clerk’s office carries the same obligations as a major transit authority.

Title III: Public Accommodations

Title III covers private businesses that serve the public. The statute names 12 broad categories, and the list is wide: hotels, restaurants, theaters, retail stores, grocery stores, banks, gas stations, laundromats, doctors’ offices, hospitals, day care centers, gyms, private schools, homeless shelters, museums, and amusement parks all qualify. Nonprofits that serve the public, like food banks and adoption agencies, are also included. Commercial facilities such as warehouses, factories, and office buildings are a separate category that must meet ADA design standards for new construction and alterations but don’t face the same barrier-removal duty for existing space.⁴

Religious organizations and private clubs are exempt from Title III. The exemption is broad: even when a religious organization runs something that would otherwise qualify as a public accommodation, like a day care or private school, Title III doesn’t apply to those operations.⁵

Who Counts as Having a Disability

The ADA defines disability as a physical or mental impairment that substantially limits one or more major life activities, such as walking, seeing, hearing, breathing, learning, or working. Major life activities also include bodily functions like immune system operation, normal cell growth, and neurological and brain function.⁶

Protection isn’t limited to people with current impairments. Someone with a record of a disability, such as a history of cancer now in remission, is covered. So is a person an employer or business treats as though they have a disability, even if they don’t. If a hiring manager passes on a candidate because she assumes his limp means he can’t do the job, that’s a potential ADA violation regardless of whether his condition actually limits him.⁶

What Employers Owe: Reasonable Accommodations

For employers under Title I, the core duty is providing reasonable accommodations so qualified employees and applicants with disabilities can perform their jobs. A qualified individual is one who can handle the essential functions of the position with or without accommodation.¹

Accommodations take many forms. The statute lists making facilities accessible, restructuring job duties, offering modified or part-time schedules, reassigning an employee to a vacant position, acquiring modified equipment, and providing readers or interpreters.¹ In practice that often means installing screen reader software, allowing remote work when a condition flares, adjusting a workspace, or making an exception to a no-animals policy for a service dog.⁷

An employer can decline an accommodation that would create an undue hardship, meaning significant difficulty or expense given the employer’s resources. It isn’t only about cost. An accommodation that would be substantially disruptive or fundamentally change how the business operates can also qualify. The analysis looks at the employer’s finances, size, and the specific accommodation requested.⁸ A multinational corporation will have a much harder time proving undue hardship than a 20-person business.

Physical Accessibility of Buildings

The 2010 ADA Standards for Accessible Design set the technical rules for how buildings must be built and modified. They apply to all new construction and significant alterations of state and local government facilities, public accommodations, and commercial facilities.⁹ The measurements are specific and cover ramp slopes, door widths, restroom turning space, grab bar placement, and sink heights.

Existing Buildings

Owners of existing public accommodations have to remove architectural barriers when doing so is “readily achievable,” which means the change can be made without much difficulty or expense given the business’s size and resources.¹⁰ Common examples include installing a small ramp over a single step, widening a doorway, or rearranging furniture to create wider paths. When full barrier removal isn’t feasible, the business has to offer another way to deliver the service.

Safe Harbor for Older Elements

Building elements constructed or altered before March 15, 2012, that already comply with the original 1991 ADA Standards, don’t have to be upgraded to the 2010 Standards. The safe harbor does not cover elements the 1991 Standards never addressed, like swimming pools, play areas, and exercise equipment. Those have to meet the 2010 Standards when making them accessible is readily achievable.

Website and App Accessibility

The Department of Justice treats websites and mobile applications as extensions of the services covered under Titles II and III. In April 2024, the DOJ formalized this for government entities by publishing a rule that adopted the Web Content Accessibility Guidelines (WCAG) version 2.1 at Level AA as the binding standard for state and local government web content and mobile apps.¹¹

Compliance deadlines depend on size. Entities serving 50,000 or more people originally faced an April 2026 deadline; smaller entities and special district governments had until April 2027. In April 2026, the DOJ extended both by a year. Larger entities now have until April 26, 2027, and smaller entities until April 26, 2028.¹¹ For private businesses under Title III there is no equivalent formal rule yet, but the DOJ and the courts have applied the same WCAG 2.1 AA standard through settlements and litigation.

What WCAG 2.1 AA Requires

In practical terms, your site or app must work for people who can’t see, hear, or use a mouse. Key requirements include alt text on every non-decorative image so screen readers can convey the content, full keyboard operability for all menus, links, forms, and interactive elements, and color contrast of at least 4.5:1 for standard text against its background and 3:1 for large text.¹² Video needs synchronized captions, and multimedia should include audio descriptions of visual content. Every form field needs a clear label, and error messages must be detectable by assistive technology.

Effective Communication

Beyond physical and digital spaces, the ADA requires that communication itself be accessible. When you interact with someone who has a vision, hearing, or speech disability, your communication has to be as effective as it would be with anyone else.

What that looks like depends on the situation. A quick retail transaction might only require pen and paper. A complex medical consultation or legal proceeding would likely require a qualified sign language interpreter or real-time captioning. For people with visual impairments, effective communication might mean Braille, large print, or electronic formats compatible with screen readers.

The business or agency pays for the auxiliary aid. You cannot charge the person with a disability for the interpreter, the Braille menu, or the assistive listening device. The choice should generally defer to the individual’s preference, though the entity can pick an alternative that results in equally effective communication.

Service Animals

Under the ADA, a service animal is a dog individually trained to perform a specific task directly related to its handler’s disability. A dog that alerts someone to an oncoming seizure, guides a person who is blind, or retrieves dropped objects qualifies. A dog whose mere presence provides emotional comfort does not, even if a therapist recommended the animal.¹³ Emotional support animals, therapy animals, and companion animals are not service animals under the ADA.

Businesses and government entities have to allow service animals wherever the public is normally permitted. When it isn’t obvious that a dog is a service animal, staff may ask only two questions: whether the animal is required because of a disability, and what task it has been trained to perform.¹⁴ Staff cannot ask what the person’s disability is, demand documentation, or require the dog to demonstrate its task. A service animal can be asked to leave only if it’s out of control and the handler isn’t managing it, or if it isn’t housebroken. Allergies and fear of dogs are not valid reasons to deny access.¹³

Enforcement and Penalties

Enforcement runs through two channels: federal agencies and private lawsuits. The Equal Employment Opportunity Commission handles employment complaints under Title I. If you believe an employer discriminated against you or refused a reasonable accommodation, you file a charge with the EEOC, which investigates and may attempt conciliation or file suit on your behalf.¹⁵

For Title II and Title III violations, the Department of Justice can investigate complaints and file civil actions when it finds a pattern of discrimination or an issue of general public importance.¹⁶ Individuals can file private lawsuits under Title III, but private plaintiffs can only obtain injunctive relief, meaning a court order to fix the violation. Monetary damages are available only in DOJ-initiated cases.

When the DOJ pursues a Title III case, civil penalties are adjusted for inflation each year. The base statutory amounts are $50,000 for a first violation and $100,000 for subsequent violations, but the current maximums stand at $118,225 for a first violation and $236,451 for each subsequent violation.¹⁷ Consent decrees in DOJ cases often require ongoing accessibility monitoring, regular reporting, and mandatory staff training. Defendants also typically pay the plaintiff’s attorney fees, which in complex cases can dwarf the underlying penalties.

Tax Credits to Offset the Cost

Two federal tax provisions help absorb accessibility spending. The Disabled Access Credit under IRC Section 44 gives eligible small businesses a credit equal to 50 percent of accessibility expenditures above $250 and up to $10,250 in a year, for a maximum annual credit of $5,000. To qualify, your business must have had gross receipts under $1 million in the prior year or employed no more than 30 full-time workers.¹⁸ Qualifying costs include interpreter services, accessible equipment, and modifications to meet ADA standards.

Any business, regardless of size, can also deduct up to $15,000 per year for expenses related to removing architectural and transportation barriers under IRC Section 190.¹⁹ Small businesses that qualify for both can use them together, taking the Section 44 credit on the first $10,250 of spending and deducting up to $15,000 of additional barrier-removal costs under Section 190.
