What the ADA Actually Covers
The Americans with Disabilities Act (ADA) is a federal civil rights law that bans discrimination against people with disabilities in employment, state and local government services, and businesses open to the public. It became law in 1990 and was strengthened by the ADA Amendments Act of 2008, which broadened the definition of disability. If you were denied a job accommodation, turned away from a store, or blocked from a government service because of a disability, the ADA is the starting point for understanding your rights.
This article explains the two situations people ask about most: workplace accommodations under Title I and access to public places and government services under Titles II and III. It is general legal information, not legal advice for your specific case.
Who Is Protected
The ADA protects a “qualified individual with a disability.” That generally means someone with a physical or mental impairment that substantially limits one or more major life activities, someone with a history of such an impairment, or someone regarded as having one. The law does not list every covered condition. Whether a specific condition qualifies depends on how it affects the person, which is one reason individual guidance from an attorney or the enforcing agency matters.
Workplace Accommodations Under Title I
Title I applies to employers with 15 or more employees, including private companies, state and local governments, employment agencies, and labor unions. It requires covered employers to provide “reasonable accommodations” to qualified applicants and employees with disabilities, unless doing so would cause the employer “undue hardship.”
A reasonable accommodation is any change to the job or work environment that enables a qualified person with a disability to apply for a job, perform the job’s essential functions, or enjoy equal benefits of employment. Common examples include:
- Changing a work schedule or allowing remote work for part of the week
- Modifying equipment or providing assistive technology
- Restructuring a job to remove non-essential tasks
- Providing a sign language interpreter or materials in an alternate format
- Allowing a service animal in the workplace
- Reassigning an employee to a vacant position they are qualified for
How to Request an Accommodation
There is no required script. You can make the request verbally or in writing to a supervisor, manager, or HR representative, and you do not have to use the words “ADA” or “reasonable accommodation.” What matters is that you let your employer know you need a change at work due to a medical condition.
- Tell your employer what part of your job is affected and that you have a medical condition
- Describe the accommodation you think would help, if you know one
- Put the request in writing and keep a copy, even if you first asked verbally
- Be ready to provide medical documentation if the disability or need is not obvious
- Continue the conversation if your employer proposes a different accommodation that would also work
Employers are not required to grant the exact accommodation you request. They must engage in good faith in what the EEOC calls an “interactive process” to find an effective option, and they can choose among effective accommodations. An employer can deny a request that would cause undue hardship, meaning significant difficulty or expense given the size and resources of the business.
Public Access Under Titles II and III
Title II covers state and local government programs, services, and activities, such as public schools, courts, DMV offices, and public transit. Title III covers “public accommodations,” a broad category that includes restaurants, retail stores, hotels, doctor’s offices, theaters, and most other businesses open to the public.
Under both titles, covered entities generally must:
- Make reasonable modifications to policies and procedures for people with disabilities
- Provide accessible routes, entrances, and facilities in new construction and alterations
- Offer effective communication, such as sign language interpreters, captioning, or materials in accessible formats, when needed
- Allow service animals in most areas open to the public
Businesses do not have to make every change requested. Title III recognizes limits such as “readily achievable” barrier removal for existing facilities and allows a business to decline a modification that would fundamentally alter the nature of its goods or services.
Workplace vs. Public Access: Quick Comparison
| Feature | Title I (Employment) | Titles II & III (Public Access) |
| Who is covered | Employers with 15+ employees | State/local government (II); most public-facing businesses (III) |
| What you can request | Reasonable accommodation in the job or workplace | Reasonable modification of policy, or physical/communication access |
| Employer/business limit | Can deny if it causes undue hardship | Can decline if it fundamentally alters services, or isn’t readily achievable |
| Where to complain | U.S. Equal Employment Opportunity Commission (EEOC) | U.S. Department of Justice, Civil Rights Division, or the relevant federal agency |
Where and How to File a Complaint
If you believe you were discriminated against in employment because of a disability, you generally must file a “charge of discrimination” with the EEOC before you can sue. According to the EEOC, you typically have 180 calendar days from the discriminatory act to file, and that deadline extends to 300 days if a state or local law also covers the same type of discrimination. Because these deadlines are strict and can vary by state, contact the EEOC as soon as possible rather than waiting.
If the issue involves a state or local government service, or a business open to the public, complaints about disability discrimination can be filed with the U.S. Department of Justice, Civil Rights Division, through ADA.gov. Some public access issues, such as accessible transportation or telecommunications, are handled by other federal agencies, so the intake process can direct you to the right one.
Jurisdiction Limits You Should Know
The ADA is a federal floor, not a ceiling. Many states and cities have their own disability rights laws that cover smaller employers, set different filing deadlines, or provide additional remedies. State human rights or civil rights agencies often accept complaints under both state law and the ADA through worksharing agreements with the EEOC. Because these rules differ by state and change over time, verify your state’s specific deadlines and coverage directly with your state civil rights agency or the EEOC field office for your area before assuming a federal timeline applies to your situation.
Documenting Your Situation
Whether the issue is a workplace accommodation or public access, clear records make it easier for an agency or attorney to evaluate your situation.
- Write down dates, names, and what was said each time you requested an accommodation or were denied access
- Save emails, texts, and any written responses from the employer or business
- Keep copies of medical documentation you provided, if any
- Note witnesses who saw or heard what happened
- Keep a copy of any complaint or charge you file, along with confirmation of the date it was submitted
When to Contact a Licensed Attorney
General information can help you understand your rights and organize your documentation, but it cannot tell you whether your specific situation is a legal violation or what it’s worth. Consider speaking with a licensed employment or disability rights attorney, or contacting the EEOC or DOJ directly, if you are close to a filing deadline, your employer has retaliated against you, or you are unsure whether your condition or situation is covered.
Frequently Asked Questions
Does my employer have to give me the exact accommodation I ask for?
No. Employers must provide an effective accommodation but can choose among options that work, as long as they engage in good faith with you to find one.
Does the ADA apply to small businesses?
Title I employment protections apply to employers with 15 or more employees. Title III public accommodation rules apply more broadly to most businesses open to the public, regardless of size, though the “readily achievable” standard for existing facilities considers a business’s size and resources.
Can I be fired for requesting an accommodation?
Retaliation for requesting a reasonable accommodation or filing an ADA complaint is generally prohibited. If you believe you were retaliated against, document what happened and contact the EEOC or a licensed attorney promptly, since retaliation claims have their own filing deadlines.
What if my state has stronger disability rights laws than the ADA?
State law can provide broader coverage or different deadlines than the federal ADA. Check with your state’s civil rights or human rights agency to understand how state law applies in addition to the ADA.
