Topic Definition
- Americans with Disabilities Act
The Americans with Disabilities Act, commonly known as the ADA, is a landmark civil rights law enacted in 1990 that prohibits discrimination against people with disabilities across many areas of public life. Modeled in part on the Civil Rights Act of 1964, it extends protections to individuals who have a physical or mental impairment that substantially limits a major life activity, as well as those with a history of such an impairment or who are perceived as having one. What sets the ADA apart is that it goes beyond simply banning discrimination - it requires covered employers to provide reasonable accommodations and obligates public accommodations to be accessible. The law is organized into five titles that address employment, public services and transportation, public accommodations and commercial facilities, telecommunications, and a set of miscellaneous provisions. Together, these titles work to ensure that qualified individuals with disabilities have equal opportunity to participate in the workplace, government programs, businesses, and communication services.
Overview
Understanding Your Rights and Protections Under the ADA
The Americans with Disabilities Act of 1990 (ADA) was signed into law on July 26, 1990, by President George H. W. Bush, and later amended with changes effective January 1, 2009.
The Americans with Disabilities Act (ADA) is a wide-ranging civil rights law that prohibits discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal.
In addition, unlike the Civil Rights Act, the ADA also requires covered employers to provide reasonable accommodations to employees with disabilities, and imposes accessibility requirements on public accommodations.
The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities in employment, transportation, public accommodation, communications, and governmental activities. The ADA also establishes requirements for telecommunications relay services.
Two agencies within the Department of Labor enforce portions of the ADA.
- The Office of Federal Contract Compliance Programs (OFCCP) has coordinating authority under the employment-related provisions of the ADA.
- The Civil Rights Center is responsible for enforcing Title II of the ADA as it applies to the labor- and workforce-related practices of state and local governments and other public entities.
To be protected by the ADA, one must have a disability or have a relationship or association with an individual with a disability. An individual with a disability is defined by the ADA as a person who has a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment. The ADA does not specifically name all the impairments that are covered.
If you have a disability and are qualified to do a job, the ADA protects you from job discrimination because of your disability. Under the ADA, you have a disability if you have a physical or mental impairment that substantially limits a major life activity. The ADA also protects you if you have a history of such a disability, or if an employer believes that you have such a disability, even if you don't.
ADA Title I - Employment
The ADA states that a covered entity shall not discriminate against a qualified individual with a disability. This applies to job application procedures, hiring, advancement and discharge of employees, worker's compensation, job training, and other terms, conditions, and privileges of employment - FAQ and Americans with Disabilities Act - ADA Employment Information
ADA Title II
Public Services including public transportation - Title II has two sections. One covers public agencies (local, county, state, etc., government and their units). That section generally requires the agencies to comply with regulations similar to Section 504 of the Rehabilitation Act. These rules cover access to all programs offered by the entity. Access includes physical access described in the Uniform Federal Accessibility Standards or the ADA Standards for Accessible Design and access that might be obstructed by discriminatory policies or procedures of the entity. The other section of Title II is specific to public transportation provided by public entities. It includes the National Railroad Passenger Corporation, along with all other commuter authorities. This section requires the provision of paratransit services by public entities.
ADA Title III
Public Accommodations (and Commercial Facilities) - No individual may be discriminated against based on disability regarding the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of public accommodation by any person who owns, leases (or leases to), or operates a place of public accommodation. "Public accommodations" include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays, among other things.

ADA Title IV
Telecommunications - This section requires that all the 1,600 some-odd telecommunications companies in the U.S. take steps to ensure functionally equivalent services for consumers with disabilities, notably those who are deaf or hard of hearing and those with speech impairments.
ADA Title V
Miscellaneous Provisions
Here is the current text of the Americans with Disabilities Act of 1990, as amended. It was originally enacted in public law format and later rearranged and published by subject in the United States Code.

How is "disability" legally defined?
According to the Equal Employment Opportunity Committee (EEOC) website, a person with a disability is anyone who:
- 1. Has a physical or mental impairment that substantially limits one or more major life activities
- 2. Has a record of such an impairment
- 3. Is regarded as having such an impairment.
This definition is somewhat controversial.
Some people feel that the wording is so vague, a person with any "minor" problem could file frivolous lawsuits for easy money. For example, they say, a person with a stiff neck could neglect certain job duties while hiding behind the ADA. However, this argument demonstrates a couple of misunderstanding about the nature of disabilities and the rules spelled out by this legislation.
First, it is difficult to objectively categorize health problems as "major" and "minor." Many people live with what are called "invisible disabilities." These are issues that are not immediately obvious to an observer because the person who lives with them may not require an apparatus such as a wheelchair or cane, and he or she may not be in any visible pain. However, these health issues can create serious obstacles for the people who live with them. There are certain kinds of heart and muscle conditions that greatly limit how much a person can move about each day.
There are also mental and emotional concerns that may not be visible to other people, but pose real challenges for those who live with them. An effort to only protect the rights of those with "major" disabilities while overlooking the "less" disabled could create real problems for people considered "not disabled enough."
Another common misconception about the ADA is that it requires businesses to change their standards, or to be overly accommodating of people with physical or mental challenges to the point of losing profit.
The truth is, this law does not require employees to change the job description of any position. This legislation is intended to target employers who will not hire, or make their offices accessible to, qualified people with disabilities. For example, a studio would not be required to hire a blind photographer, but they would not be allowed to turn down a photographer who uses a wheelchair simply because they prefer not to build a ramp.
UPDATE: 2015-08-03
The U.S. Access Board has released new chapters of its online guide to accessibility standards under the Americans with Disabilities Act and the Architectural Barriers Act.
This guide features a series of technical bulletins covering requirements for accessible routes in Chapter 4 of the ADA and ABA Standards, including doors and gates, ramps and curb ramps, and elevators and platform lifts. There is also a bulletin on referenced requirements for accessible means of egress. The documents explain and illustrate requirements in the standards, answer common questions, and offer best practice recommendations.
The online guide features a popular series of animations that covers wheelchair maneuvering, entrances and doors, and toilet and bathing facilities. The new installment adds to the series an animation on hazards that protruding objects pose to people with vision impairments.
- The Guide to the ADA Standards covers design requirements for places of public accommodation, commercial facilities, and state and local government facilities covered by the ADA.
- The Guide to the ABA Standards addresses similar standards that apply under the ABA to facilities that are designed, constructed, altered, or leased with federal funds.

Frequently Asked Questions
How do I file an ADA complaint?
Complaints can be filed with the appropriate federal agency depending on the issue, such as the EEOC for employment matters or the Department of Justice for public accommodation concerns. Each agency has its own process and deadlines, so it is important to act promptly and keep records of the discrimination.
Does the ADA apply to small businesses?
Yes, though some requirements depend on the size of the business, with employment provisions generally applying to employers with 15 or more employees. Public accommodation rules under Title III apply broadly to businesses that serve the public regardless of size.
What is considered a reasonable accommodation under the ADA?
A reasonable accommodation is a change to a job or work environment that enables a qualified person with a disability to perform essential duties, such as modified equipment or flexible scheduling. Employers must provide it unless doing so would cause significant difficulty or expense.
Are emotional support animals covered by the ADA?
The ADA specifically recognizes service animals that are trained to perform tasks for a person with a disability, which does not automatically include emotional support animals. Other laws, such as those covering housing and air travel, may address emotional support animals separately.
Does the ADA require existing buildings to be renovated?
Existing public accommodations must remove architectural barriers when it is readily achievable, meaning it can be done without much difficulty or expense. New construction and major alterations, however, must fully meet current accessibility standards.
How is the ADA different from Section 504 of the Rehabilitation Act?
Section 504 applies specifically to programs and entities that receive federal funding, while the ADA extends similar protections to private employers, businesses, and state and local governments. The two laws often overlap but cover different scopes of activity.
Can an employer ask about my disability during a job interview?
Employers generally cannot ask about the existence or nature of a disability before making a job offer, though they may ask whether you can perform the essential functions of the role. After a conditional offer, medical questions are allowed if applied consistently to all candidates.
