A reasonable accommodation is a change to a job, a workplace, or the way work is normally done that lets a qualified employee or applicant with a disability apply for a job, perform their essential duties, or enjoy the same benefits as everyone else. Under federal law, most private employers with 15 or more employees must provide reasonable accommodations unless doing so would cause an "undue hardship" — meaning significant difficulty or expense. The right comes from the Americans with Disabilities Act (ADA), which is enforced by the U.S. Equal Employment Opportunity Commission (EEOC).
In everyday terms, an accommodation removes a barrier created by a disability so a worker can do the job. It is not special treatment or a lower performance standard. The employee still has to be qualified and still has to do the core parts of the job — the accommodation just changes how, when, or where some of that happens.
The federal baseline: where the right comes from
The main law is the Americans with Disabilities Act of 1990, as amended by the ADA Amendments Act of 2008, which deliberately broadened who counts as having a disability. For employees of the federal government and many federal contractors, the parallel protections come from the Rehabilitation Act of 1973 (Sections 501 and 503). The EEOC enforces the employment side of the ADA and also handles disability charges for federal workers through a separate process.
Three pieces have to line up for the accommodation duty to apply:
You have a disability under the ADA. That means a physical or mental impairment that substantially limits one or more major life activities, a record of such an impairment, or being regarded as having one. After the 2008 amendments, this is interpreted broadly and covers many conditions — including ones that are episodic or in remission, like epilepsy, diabetes, PTSD, major depression, cancer, or chronic migraines — judged without regard to medication or other mitigating measures.
You are a "qualified" individual. You meet the skill, experience, and education requirements of the job and can perform its essential functions — the core duties — with or without an accommodation.
The employer is covered. Federal ADA coverage starts at 15 or more employees. Many state laws cover much smaller employers (see below).
The duty also extends beyond performing the job itself. Employers must accommodate disabilities in the application process and must give workers with disabilities equal access to benefits and privileges of employment, such as training, cafeterias, parking, and employer-sponsored events.
Real examples of reasonable accommodations
Accommodations are highly individual — what works depends on the person, the disability, and the job. These are common, real-world examples that courts and the EEOC routinely treat as reasonable:
Schedule and leave changes: a modified or part-time schedule, a later start time for someone whose medication causes morning drowsiness, breaks to monitor blood sugar, or a block of unpaid leave to recover from surgery or manage a flare-up.
Physical workspace changes: an ergonomic chair, a sit-stand desk, a wheelchair-accessible workstation, better lighting, or moving a workspace closer to a restroom or accessible entrance.
Equipment and technology: screen-reading software, a screen magnifier, captioning, a TTY or video relay, voice-recognition software, an amplified phone, or a specialized keyboard.
Telework or remote work: allowing some or all duties to be done from home when the essential functions can be performed there.
Job restructuring: reassigning marginal (non-essential) tasks to other employees while the worker keeps the core duties.
Policy modifications: letting an employee with a disability use accrued leave differently, allowing a service animal, or adjusting a dress-code or no-food-at-desk rule for a medical reason.
Communication and support aids: a sign-language interpreter for meetings, written instructions instead of verbal-only, or a quiet space for someone with sensory sensitivities.
Reassignment to a vacant position: when no accommodation lets the worker keep their current job, moving them to an existing open role they are qualified for. This is generally treated as the accommodation of last resort.
Importantly, an employer does not have to: eliminate an essential function of the job, lower production or quality standards, provide personal-use items (like a wheelchair you use everywhere), or create a brand-new position. It also does not have to give you the exact accommodation you ask for — only an effective one. If two options both work, the employer can choose the cheaper or easier one.
The "interactive process": how a request actually works
Once you ask for help because of a medical condition, the ADA expects the employer to start an interactive process — a good-faith back-and-forth to figure out what barrier you face and what would remove it. You do not have to use the words "reasonable accommodation" or "ADA." Saying something like "I'm having trouble doing X because of my medical condition and I need a change" is enough to put the employer on notice.
During this process the employer may ask for reasonable documentation confirming you have a disability and need the accommodation — but only when the disability or need is not obvious. They are entitled to information about your functional limitations, not your entire medical history or a specific diagnosis label. Any medical information must be kept confidential and stored separately from your regular personnel file.
Undue hardship: the main limit
An employer can refuse an accommodation only if it would cause an undue hardship — significant difficulty or expense — judged against factors like the cost, the employer's overall size and resources, and the effect on operations. The bar is meaningful: minor inconvenience or general grumbling about fairness does not count, and a large company cannot claim that a modest cost is a hardship just because it would be for a small one. Many accommodations cost little or nothing. If one specific accommodation truly is a hardship, the employer still has to consider alternatives that would work.
Where state law adds stronger protections
The ADA is a floor, not a ceiling. State fair-employment laws frequently go further, and this varies by state. Common ways state law is stronger include:
Smaller employers covered. Many states apply their disability laws to employers with far fewer than 15 employees — sometimes as few as one.
Broader definitions of disability or a tougher standard for proving undue hardship.
Separate accommodation rights for pregnancy, childbirth, and related conditions. At the federal level, the Pregnant Workers Fairness Act now requires reasonable accommodations for pregnancy and related conditions for covered employers, and many states have had similar laws for years.
State-enforced complaint systems through a state civil rights agency or labor department, sometimes with longer filing windows than the federal one.
Because the details differ so much, check your own state's fair-employment agency rather than assuming the federal rule is the only one that applies.
Practical steps: how to request and protect your rights
Make the request clearly, ideally in writing. Email or a written note creates a record of what you asked for and when. State that you have a medical condition and describe the change you need and why.
Direct it to the right person. Usually your supervisor, HR, or a designated disability or leave coordinator. Follow any written accommodation policy if your employer has one.
Document everything. Keep copies of your request, the employer's responses, dates of conversations, and any denials or delays. Note who said what.
Be ready with focused medical support. A letter from your provider describing your limitations and suggested accommodations is often enough — you do not have to hand over full records.
Engage in the back-and-forth. If the employer offers an alternative that works, that can satisfy the law even if it isn't your first choice. If it doesn't work, explain specifically why and propose another option.
Watch for warning signs. Long unexplained delays, a flat refusal to discuss anything, or discipline that appears soon after you asked can all be problems. An employer that ignores a request or shuts down the interactive process may be violating the ADA.
If your request is denied or you face retaliation
It is illegal under the ADA to fire, demote, cut hours, harass, or otherwise punish you for requesting an accommodation or for filing a complaint — that is retaliation, and it is a separate violation even if your underlying accommodation request turns out not to be required.
If you cannot resolve things internally, you can file a charge of discrimination with the EEOC (or your state or local fair-employment agency, which are often connected to the EEOC through a work-sharing agreement). There is a strict deadline to file, and it depends on your state and whether a state or local agency also covers your claim — generally a matter of months from the discriminatory act, not years — so do not wait. Filing a timely charge with the EEOC is usually a required step before you can take an ADA claim to court. Many people consult an employment lawyer at this stage; a number of them offer free initial consultations.

The law behind your rights at work
The ADA requires reasonable accommodation and an interactive process; the EEOC enforces it.
Your state and city matter. Federal law is the floor — many states and cities require higher pay, more leave, and broader protections. Always check your state’s rules (and any local ordinances) in addition to the federal laws above. This is general legal information, not legal advice.
Frequently asked questions
What does reasonable accommodation mean in plain English?
It means a change to your job, your workspace, or how the work is normally done so that a qualified worker with a disability can do the job or apply for it. It removes a barrier caused by a disability — like a flexible schedule, special software, or telework — without lowering the core standards of the job. Under the ADA, covered employers must provide it unless it would cause significant difficulty or expense.
What are common examples of ADA accommodations?
Frequent examples include modified or part-time schedules, unpaid leave for treatment or recovery, ergonomic equipment, screen readers or other assistive technology, telework, reassigning minor non-essential tasks, sign-language interpreters, a quiet workspace, and — as a last resort — reassignment to a vacant position the worker is qualified for. The right accommodation depends on the person, the disability, and the job.
Do I have to disclose my diagnosis to get an accommodation?
Usually not. If your disability or need isn't obvious, the employer can ask for reasonable documentation showing you have a covered condition and need a change — but they are entitled to information about your functional limitations, not your full medical records or a specific diagnosis label. Any medical information they receive must be kept confidential and stored separately from your personnel file.
Can my employer just say no to my request?
Only in limited situations. An employer can deny a specific accommodation if it would cause an undue hardship — significant difficulty or expense given its size and resources — or if you can't perform the essential functions even with help. But it can't refuse to discuss the request at all, and it must consider effective alternatives. It can pick a cheaper option as long as it actually works.
What can I do if my accommodation is denied or I'm punished for asking?
Document the request, the response, and any discipline or schedule changes that followed. Retaliation for requesting an accommodation is itself illegal under the ADA. If you can't resolve it internally, you can file a charge with the EEOC or your state fair-employment agency. There is a strict filing deadline that varies by state, generally measured in months, so act promptly and consider consulting an employment attorney.
