What Are ADA Reasonable Accommodation Requirements?

Under the Americans with Disabilities Act, reasonable accommodation requirements obligate covered employers to change how, when, or where work gets done so that a qualified employee or applicant with a disability can do the job, unless the change would cause the business significant difficulty or expense. Refusing to accommodate a disability the employer knows about is itself a form of discrimination.¹ The mechanics are more informal than most people expect, and knowing them helps on both sides of the conversation.

Which Employers Are Covered

The ADA’s employment rules apply to private employers with 15 or more employees for each working day during at least 20 calendar weeks in the current or preceding year. State and local governments are covered as employers once they meet the same threshold.² Smaller businesses fall outside these federal requirements, though many states have their own disability discrimination laws that reach smaller employers.

You also have to be a “qualified individual” — someone who can perform the essential functions of the job with or without a reasonable accommodation.³ Essential functions are the core duties the position exists to carry out, not every task that happens to be listed on a job description. A written job description prepared before the position was advertised counts as evidence of what those core duties are. You do not have to be able to handle every peripheral task; you have to be able to handle the fundamentals, possibly with a workplace adjustment.

What Counts as a Reasonable Accommodation

A reasonable accommodation is any change to a job, the work environment, or the way things are normally done that lets a person with a disability apply, work, or enjoy the same benefits of employment as anyone else. The statute lists examples: making facilities accessible, restructuring duties, adjusting schedules, reassigning to a vacant position, modifying equipment, and providing readers or interpreters.⁴ The list is illustrative, not exhaustive.

In practice, that covers ergonomic workstations, screen-reading software, modified break schedules for medical needs, reserved parking closer to the entrance, noise-canceling headphones in an open office, or permission to bring a service animal to work. An accommodation is effective when it removes the specific barrier interfering with your ability to do the job. It does not have to be your first choice. It just has to work.

What Employers Do Not Have to Provide

Personal-use items an employee needs both on and off the job are outside the requirement. Hearing aids, eyeglasses, wheelchairs, and prosthetic devices address daily living rather than a workplace-specific barrier.⁵ The exception is an item specifically designed to meet a job-related need, such as a magnification device that only matters for a particular work task.

Remote Work

Working from home can be a reasonable accommodation when a disability keeps you from commuting or working on-site, and the essential functions can be performed remotely. Employers are not required to grant remote work if effective in-office alternatives exist, whether that means modified equipment, environmental changes, or a flexible schedule. Remote work becomes mandatory only when the other options have proven ineffective.⁶ Blanket policies denying every remote work request without an individualized look don’t satisfy the ADA.

Reassignment as a Last Resort

When no accommodation lets you perform the essential functions of your current position, the employer must consider reassignment to a vacant position you are qualified for. This is the accommodation of last resort and only comes into play after other solutions have been ruled out or would cause undue hardship.⁵ The employer does not have to create a new position or displace another worker to open one up. If an equivalent job is not available, the employer should offer a lower-level vacancy, and is expected to notify you of openings you may be eligible for.

How to Request an Accommodation

Requesting an accommodation is far less formal than most employees assume. You don’t need to use the words “reasonable accommodation,” cite the ADA, or fill out a specific form. Telling your supervisor or HR that you need a change at work because of a medical condition is enough to put the employer on notice.⁵ A family member, doctor, or other representative can make the request for you. The moment the employer knows you need a workplace change tied to a disability, the legal clock starts running.

What comes next is an informal back-and-forth called the interactive process. Both sides talk through the limitations, possible changes, and what’s feasible for the workplace. There is no set number of days for the employer to respond, but the EEOC requires employers to act expeditiously and warns that unnecessary delays can themselves violate the ADA.⁵ If your initial suggestion isn’t feasible, the employer should propose alternatives. The dialogue continues until an effective solution is found or the employer formally denies the request based on undue hardship.

When You’ll Need Medical Documentation

Documentation isn’t always part of the process. When both the disability and the need for accommodation are obvious — a wheelchair user asking for a ramp, for instance — the employer cannot demand medical paperwork.⁵ When the condition or the connection to the requested change isn’t apparent, the employer may ask for reasonable documentation. That typically means a statement from your healthcare provider describing your functional limitations rather than just a diagnosis. “I cannot sit for more than 30 minutes without a break” is more useful than “I have a back condition.”

If what you provide is insufficient, the employer should tell you what’s missing and give you a chance to supplement it. Only after that can the employer require you to see a healthcare provider of its choosing, and the employer pays for that visit.⁷ Employers can also consult your doctor directly, but only with your written consent.

How Your Medical Information Must Be Handled

Any medical information the employer collects during the accommodation process has to be kept in separate files, apart from your regular personnel records, and treated as a confidential medical record.¹ That applies to paper and electronic records alike. Your coworkers should not have access to your diagnosis, and the employer cannot share it freely within the organization.

The statute allows only three narrow exceptions for who can see your medical information:

Supervisors and managers may be told about specific work restrictions or accommodations you need, but not the underlying diagnosis.
First aid and safety personnel may be informed if your condition could require emergency treatment.
Government officials investigating ADA compliance can request relevant records.

So your manager might know you need a standing desk and a modified schedule but should not know why. Casual sharing of your medical details with anyone outside those categories is itself a violation.

When an Employer Can Say No

The obligation to accommodate has limits. An employer can deny a request that would cause undue hardship, meaning significant difficulty or expense relative to the employer’s resources.³ This is not a fixed dollar test. The analysis weighs the cost against the employer’s overall financial resources, the size and structure of the business, and the impact on operations. A $5,000 modification might be reasonable for a large retailer and genuinely burdensome for a ten-person office on tight margins.

The employer bears the burden of proving undue hardship. Vague claims about cost or inconvenience are not enough; the employer has to show specific, concrete reasons. And even if the preferred accommodation is too costly, the employer still has to offer an effective alternative if one exists.

Direct Threat

An employer can also decline to accommodate when the individual poses a direct threat, meaning a significant risk to the health or safety of others that cannot be eliminated through reasonable accommodation.³ The determination has to rest on an individualized assessment using current medical evidence, not stereotypes or generalized fears about a condition. The employer must consider the duration of the risk, the severity of potential harm, the likelihood it will occur, and whether any accommodation could bring it to an acceptable level.

Conflicts With Seniority Systems

Reassignment gets complicated when a collective bargaining agreement or seniority system gives another worker priority for the vacant role. Bumping a more senior employee to accommodate a disability is generally treated as unreasonable because it undermines the expectations that seniority systems are built on.⁵ There’s an exception for “special circumstances” that weaken those expectations, such as when the employer has a history of unilaterally changing seniority rules or the system already includes procedures for granting exceptions. In a lawsuit, the employee has to demonstrate those special circumstances first.

Protection Against Retaliation

Asking for an accommodation is a protected activity. Your employer cannot fire you, demote you, cut your hours, or take any other adverse action against you for requesting a workplace change tied to a disability.⁸ The protection extends to anyone who helps you, including a coworker who assists with your request or a witness who takes part in an EEOC investigation.

The ADA also prohibits interference with disability rights. An employer that pressures you to withdraw a request, hints that asking will hurt your career, or discourages a coworker from supporting you is violating this provision even if no formal adverse action follows.⁹ A threat doesn’t have to be carried out to be actionable, and you don’t have to prove you were actually deterred.

Filing a Charge and Available Remedies

If your employer refuses the interactive process, denies an accommodation without justification, or retaliates against you, you can file a charge with the U.S. Equal Employment Opportunity Commission. The filing deadline is 180 calendar days from the date of the discriminatory act. In states that have their own agency enforcing disability discrimination laws, which is most states, the deadline extends to 300 days.¹⁰ Weekends and holidays count toward the total, but if the deadline itself falls on a weekend or holiday, you have until the next business day. Missing the window generally forfeits the claim.

After you file, the EEOC investigates and tries to resolve the charge. You generally have to give the agency 180 days before requesting a Notice of Right to Sue, which you need to file a lawsuit in federal court.¹¹ In some situations, the EEOC will issue the notice earlier. If the agency finds a violation but cannot reach a settlement, it may sue on your behalf or refer the case to the Department of Justice.

ADA remedies include back pay, reinstatement or front pay, and compensatory damages for emotional distress. Federal law caps combined compensatory and punitive damages based on the employer’s size:¹²

15–100 employees: $50,000
101–200 employees: $100,000
201–500 employees: $200,000
More than 500 employees: $300,000

The caps apply per person and cover compensatory and punitive damages combined. Back pay and attorney’s fees aren’t included. Courts can also order the employer to change its policies, provide the denied accommodation going forward, or take other corrective action.
