Everything quoted below comes from one document: EEOC Enforcement Guidance on Reasonable Accommodation and Undue Hardship under the ADA, Notice 915.002, dated October 17, 2002, re-read at eeoc.gov on September 4, 2026. It is enforcement guidance rather than statute, and it says so about itself: its contents “do not have the force and effect of law and are not meant to bind the public in any way.” It also carries a banner noting it was issued before the ADA Amendments Act of 2008 took effect. That does not make it unimportant — it is how the agency that enforces Title I says it reads the law — but nothing here tells you whether a particular choice in your workplace would be lawful. For that, use employment counsel. For accommodation practicalities, the Job Accommodation Network consults with employers free and confidentially at 800-526-7234.
An employee asks for a specific accommodation. You can see a different one that would also work, and it is cheaper, or faster, or simply easier to run. Are you allowed to offer that instead?
This is the question employers actually get stuck on, and it is close to unwritten. There is a great deal published on how to start the accommodation conversation and almost nothing on how to decide inside it. The short answer is yes, there is a genuine choice. The useful answer is that the choice is much narrower than the short answer sounds, and an employer who acts on the short answer alone will frequently be wrong.
The Sentence Everyone Half-Remembers
Here it is in full, because the half-remembered version is where the trouble starts:
“The employer may choose among reasonable accommodations as long as the chosen accommodation is effective.”
And on whose preference counts: “the preference of the individual with a disability should be given primary consideration. However, the employer providing the accommodation has the ultimate discretion to choose between effective accommodations.”
Read the first quotation with the emphasis in the wrong place and you get “the employer may choose.” Read it with the emphasis where the sentence actually puts it and you get something much more demanding: as long as the chosen accommodation is effective. That clause is not a caveat attached to the rule. It is the rule. The discretion only exists in the space where two or more options are already effective, and getting into that space is work you have to have done first.
Four Things That Bound the Choice
1. Effective for that person, in that job
The guidance defines what effective means, and it is concrete rather than abstract: an accommodation is effective when it removes a workplace barrier, thereby providing the person with an equal opportunity to apply for a position, to perform the essential functions of a position, or to gain equal access to a benefit or privilege of employment. Not effective in general. Not effective for someone else with a similar diagnosis. Effective for this person, in this job, against this barrier.
Which means the alternative you have in mind is not an alternative yet. It is a hypothesis, and there is exactly one way to test it.
2. You have to have actually asked
The test runs through the conversation you were already required to have. The guidance places the choice inside it explicitly: “as part of the interactive process, the employer may offer alternative suggestions for reasonable accommodations and discuss their effectiveness in removing the workplace barrier.” Offer and discuss. Not decide and inform.
This is the step that gets skipped, and skipping it is not a procedural blemish. It is the difference between exercising a choice the guidance describes and substituting your judgment for information you never collected. We have covered the process itself at length — our ADA basics for small employers is the place to start if that part is new — so this article stays on the choice rather than re-explaining the conversation around it.
3. Preference is not the same as effectiveness, and it is not nothing
The guidance gives the employee's preference “primary consideration” and then gives the employer “ultimate discretion.” Those two phrases sit in consecutive sentences, and employers tend to remember the second.
The sequence they describe is worth getting right. Preference comes first and carries real weight in the discussion. Discretion is what remains after effectiveness has been established for more than one option. An employer who reaches for discretion before effectiveness has been settled has not used the rule; they have used its second half as a shortcut past its first.
There is also a practical argument that has nothing to do with compliance. The person asking has usually lived with the barrier for years and tried things. Treating their preference as information rather than as a demand to be managed is, more often than not, the fastest route to the answer.
4. Cost is a tiebreaker, not a test
This is where two separate standards get welded together, so they are worth keeping apart.
Choosing between effective options. The guidance is direct: “If there are two possible reasonable accommodations, and one costs more or is more burdensome than the other, the employer may choose the less expensive or burdensome accommodation as long as it is effective… In either situation, the employer does not have to show that it is an undue hardship to provide the more expensive or more difficult accommodation.”
Refusing an accommodation altogether. Different standard entirely. “Undue hardship” means “significant difficulty or expense” measured against the resources and circumstances of the particular employer, assessed case by case, and covering accommodations that are unduly extensive, substantial or disruptive as well as expensive ones.
So cost can decide between two options that both work. Cost cannot make an option that does not work into one that does, and “that is expensive” is not an undue hardship finding — it is the beginning of an analysis with a much higher bar. Our guide to what accommodations actually cost is the companion to this section, and it is worth reading before assuming which of your two options is the expensive one.
The Failure Mode, Named
An employee asks for A. The employer can see that B is cheaper, decides B is “basically the same thing,” provides B without discussing it, and considers the matter handled under a rule they have heard about. Then B does not work, the employee says so, and the employer feels they have already accommodated once.
What went wrong is not the preference for B. It is that B was never established as effective before it was chosen, which means the choice the guidance describes was never actually available. The employer did not exercise discretion. They skipped the step that creates it.
If you are already in that situation, the recovery is not complicated and it is not an admission of anything: go back and have the conversation. Our piece on reopening the conversation when an accommodation stops working is written from the employee's side, and it is the same move from either chair.
Reassignment Sits at the End, and Has Its Own Rules
Reassignment to a vacant position is on the list of reasonable accommodations, and employers reach for it early far more often than the guidance supports. It has an explicit place in the order:
“Before considering reassignment as a reasonable accommodation, employers should first consider those accommodations that would enable an employee to remain in his/her current position. Reassignment is the reasonable accommodation of last resort and is required only after it has been determined that: (1) there are no effective accommodations that will enable the employee to perform the essential functions of his/her current position, or (2) all other reasonable accommodations would impose an undue hardship.”
Last resort, and conditional on one of two determinations that have to have been made rather than assumed. The guidance does note that reassignment can be reached sooner where both parties voluntarily agree a transfer is preferable, which is a different situation and turns on the word voluntarily.
The reason to be careful here is that a move out of a job someone has done well reads very differently from the inside than it does on an org chart, and it is not interchangeable with keeping them where they are. Our stay-at-work playbook covers the part that comes before this one, which is where most of the useful work happens.
A Sequence You Can Actually Follow
- Take the request as a starting position, not a final one. It opens a discussion; it does not close one.
- Say your alternative out loud, early, as a question. Not “we will be doing B instead” but “would B remove the same barrier for you?” That single change is most of the difference between the two versions of this rule.
- Establish effectiveness before you compare anything. Cost, ease and preference are all irrelevant until at least two options have cleared that bar.
- Only then use your discretion, and know that is what you are doing.
- Write down why. Not for the file, for the next conversation. If the chosen option turns out not to work, you want a record of what was considered and on what basis, and so does the person living with it.
- Leave reassignment where it belongs, which is after the rest, not instead of it.
When the question is genuinely “would this alternative work,” the Job Accommodation Network exists precisely for it. Free, confidential, funded by the U.S. Department of Labor, and staffed by consultants who have seen the situation you are describing many times. They will not tell you what the law requires of you in your case, which is what counsel is for. They will very often tell you about a third option neither you nor the employee had considered, which is better than winning the argument about the first two.
None of this guarantees an outcome, and this article cannot tell you how any particular decision would be judged. What it can tell you is where the discretion in the rule comes from, which is entirely from the work done before it: the asking, the discussing, and the establishing of what actually removes the barrier. Employers who do that part reliably find the choice is rarely the hard bit. It is usually already obvious by the time they get to it.
