This is general information rather than legal advice. Your regional ADA Center offers free guidance, and the Job Accommodation Network advises on specific accommodations at no cost.
Most people think asking for an accommodation is a request that gets a yes or a no.
It isn’t. It starts a legally defined process with obligations on your employer, and knowing what those obligations are changes the conversation completely. Almost no employee knows this, and a fair number of employers don’t either.
What a Reasonable Accommodation Is
A change to how, when, or where work gets done, so that a person with a disability can do the job or access the same benefits as everyone else.
That’s deliberately broad. Modified schedules, remote work, different equipment, restructured duties, reassignment of marginal tasks, leave, changes to how a supervisor communicates, physical changes to a workspace. The test isn’t what category it falls into; it’s whether it removes the barrier.
Employers with fifteen or more employees are covered under Title I. Some state laws set a lower threshold; California’s is five, so check yours before assuming you’re outside it.
There Are No Magic Words
You don’t have to say “reasonable accommodation.” You don’t have to mention the ADA. You don’t have to fill in a form unless your employer has one.
The EEOC is explicit that a person can use plain English. Telling your employer you need a change at work for a reason related to a medical condition is a request, legally, and it starts the clock.
That matters because people delay for months, waiting until they can phrase it properly. You already know how to phrase it.
The Interactive Process
Here’s the part nobody tells employees.
Once you make a request, your employer is required to initiate an informal, interactive process with you to identify your precise limitations and work out what would address them. That obligation is written into the regulations, and the EEOC’s enforcement guidance on reasonable accommodation sets out how it’s supposed to work.
It’s a conversation with rules, not a decision made about you elsewhere.
Your employer is also expected to respond expeditiously rather than sitting on it. Delay is itself a form of failure to accommodate, and a request that goes unanswered for months is a problem in its own right.
You Don’t Have to Bring the Solution
This one stops people from asking at all.
If you can describe the problem but not the fix, that’s enough. The EEOC specifically identifies it as an employer error to refuse to act or to put the entire burden of finding a solution on the employee. Your employer is supposed to engage, explore options, and consult outside resources if they don’t know the answer.
Free resources exist precisely for this. The Job Accommodation Network provides confidential guidance to employers and employees on specific accommodations, at no cost, and an employer who hasn’t used it hasn’t really tried.
So “I’m struggling with X, and I don’t know what would help” is a legitimate opening. You are not required to arrive with a proposal.
If They Rule Out Your Idea, They Can’t Stop There
This is the single most useful thing on this page.
Suppose you ask for something specific and your employer says no because it’s too expensive, or wouldn’t work, or would remove an essential function. Plenty of employers treat that as the end of the conversation.
It isn’t. EEOC guidance names this as a mistake directly: where a requested accommodation is ineffective, would cause undue hardship, or isn’t legally required, the employer should continue the interactive process, exploring alternatives until either a workable accommodation is found or they determine that none exists without undue hardship.
Which means a no to your suggestion is not a no to accommodation. If the conversation ends there, the process has failed, and that failure is the thing to point at.
Effective Isn’t the Same as Technically Provided
Your employer gets to choose between options. If two accommodations would both work, they can pick the cheaper or easier one, and that’s legitimate.
The catch is that whatever they choose has to actually be effective.
The EEOC’s own example is a lawyer with a visual impairment who asked for a reader. Her employer provided a magnifying device instead. She could read with it, technically, but so slowly that she couldn’t perform at the same level as her colleagues, which meant she couldn’t compete for promotion on equal terms. The guidance is clear that the magnifier wasn’t a reasonable accommodation, and that failing to provide the reader would violate the ADA.
So the question isn’t whether they gave you something. It’s whether what they gave you puts you on equal footing. If it half works, it hasn’t worked.
What They Can Ask For
If your disability and your need aren’t obvious, your employer can ask for documentation. That’s legitimate, and it has limits.
What they can request is information that’s job-related and consistent with business necessity. Confirmation that you have a condition and that it creates limitations requiring accommodation. What they can’t demand is your complete medical history or unrestricted access to your records.
A letter from your clinician generally needs to establish that a condition exists, describe the functional limitations it causes, and connect those limitations to the accommodation being requested. It does not need to name a diagnosis in many cases.
Anything you do provide has to be kept confidential and stored separately from your personnel file, including from your colleagues and your direct manager beyond what they need to know.
Undue Hardship, and What It Actually Means
The only lawful reason to refuse an effective accommodation is undue hardship, meaning significant difficulty or significant expense.
Significant is assessed against the employer’s overall resources, not the budget of one department or one manager’s discretionary spend. A large employer refusing a modest cost on the grounds that a particular team can’t absorb it is not making the argument they think they are.
And it has to be an actual analysis. Employers are not permitted to reject a request outright on cost grounds without engaging in the interactive process in good faith first.
Worth knowing that the majority of accommodations cost very little, and a substantial proportion cost nothing at all. Undue hardship is a real defense, and it’s invoked far more often than it applies.
Put It in Writing, and What to Include
You aren’t required to. Do it anyway, because it creates a date and a record.
Name the limitation, not the diagnosis. “I have difficulty sustaining concentration in an open-plan area” is more useful than a condition name and gives them something to solve.
Connect it to the job. Which tasks are affected, and how.
Propose something if you have an idea, and say explicitly that you’re open to alternatives. That signals good faith and keeps the process open if your suggestion gets ruled out.
Ask for a response by a specific date. Reasonable, and it makes delay visible.
Keep a copy somewhere that isn’t work email. People lose access to their accounts the day things go wrong.
If It Stalls or Gets Refused
Silence is a response, and not a lawful one. If weeks pass, follow up in writing and reference the date of your original request.
If the answer is no, ask for it in writing and ask for the reason. An employer who won’t put a refusal on paper is telling you something.
Then check three things. Did they engage in the interactive process at all, or just decide? When they ruled out your suggestion, did they explore alternatives? And is the accommodation they offered instead genuinely effective, or does it half work?
A failure at any of those points is not a disappointing outcome. It’s a potential violation, and it comes with a deadline that’s shorter than most people expect, which is covered in the piece on disability discrimination and how to file.
Your regional ADA Center will also talk it through for free before you decide whether to escalate.
The Sentence That Starts It
All of this begins with one plain sentence about needing a change at work because of a medical condition. No form, no legal language, no diagnosis required.
What follows is supposed to be a conversation with rules, and knowing the rules is most of the advantage. If you want the wider picture of which law covers what, that’s in what the ADA actually is, and if the condition in question is a mental health one, the specifics of asking for that are worth reading alongside this.
