Do ADA Accommodation Letters Expire? Renewals and Updated Documentation

The short answer

The Americans with Disabilities Act does not say that accommodation letters expire. There is no federal expiration date and no requirement that letters be renewed annually. Once an employer has accepted documentation supporting a reasonable accommodation, that accommodation generally stays in place for as long as the underlying condition continues.

That's the formal answer. The practical answer has more nuance, and that's what this guide is about.

When employers can ask for updated documentation

The EEOC's enforcement guidance explains that employers can request additional documentation only when there is a legitimate reason to do so. They cannot ask for updates as a routine matter or as a pretext for revisiting an accommodation they've already approved.

There are a few situations where a renewal request is generally appropriate.

The original letter recommended a specific duration. Many letters include language like "this accommodation is recommended for the next 12 months, with periodic review." If the duration in the letter has elapsed, the employer can reasonably ask for an update.

The original letter described a condition with anticipated improvement or change. If the documentation suggested the limitation might resolve (a recovery from a major depressive episode, a course of treatment for an acute condition), the employer may legitimately ask for an update once that anticipated timeline has passed.

The job has changed. If the employee's role, duties, or work environment has materially changed since the original accommodation was granted, the employer can reasonably ask for documentation that addresses the new circumstances.

A request to modify or expand the accommodation. If you're asking for a different or additional accommodation, the employer can ask for documentation that supports the new request.

A new condition is being raised. If you're adding a new condition (you originally got an accommodation for anxiety and now want one for a co-occurring physical health condition), updated documentation is appropriate.

When employers cannot ask for updated documentation includes routine annual recertification with no specific reason, requests timed to performance issues that have nothing to do with the accommodation, requests during managerial transitions designed to relitigate a previous decision, and requests for the underlying medical records or detailed clinical history rather than functional capacity documentation.

The general principle: documentation requests must be reasonable, job-related, and consistent with business necessity. The EEOC has detailed guidance on what's appropriate.

Why some letters include duration

If you've worked with a clinician who recommends a specific duration in the letter, that's not random. There are good reasons to include one for some conditions and not for others.

Permanent or chronic conditions. Conditions like autism, ADHD, bipolar disorder, and many chronic anxiety disorders are lifelong. Letters for these conditions often state "indefinite, with periodic review every 12 to 24 months" or simply omit a duration. The point is that the accommodation should not be presumed temporary.

Conditions with expected change. Conditions like a depressive episode, post-traumatic stress with active treatment, or recovery from acute symptoms may legitimately have a defined duration. The letter might recommend a 12-month accommodation with a check-in point built in.

Time-limited stressors. If the accommodation is tied to a specific situation (caregiving for a family member's terminal illness, recovery from a workplace incident), the duration may match the underlying situation.

A reasonable best practice for most chronic mental health conditions is to include language like "this accommodation is recommended on an ongoing basis. The patient's condition is expected to be lifelong. A periodic review every 12 to 24 months may be appropriate, but no specific expiration is recommended at this time." This pre-empts the recurring "is this still needed?" conversation.

What to do when HR asks for updated documentation

If HR contacts you asking for updated documentation, the path forward depends on whether the request is reasonable.

If the request is reasonable (the original letter's duration has elapsed, your role has changed materially, or you're asking for a new accommodation), the simplest move is to provide updated documentation promptly. Stalling on a reasonable request can be used by employers as evidence that the employee is no longer engaged in good-faith interactive process.

If your original clinician is no longer available, no longer responsive, or wasn't a good fit, you can use a different qualified provider for the renewal. Continuity is helpful but not required. The WashU-hosted resource on the interactive process has a useful section on documentation refreshes.

If the request seems unreasonable (annual recertification with no specific reason, timed to a manager change, requesting medical records rather than functional documentation), you have options. First, ask HR in writing for the specific reason for the request and what specific information they need. The reasonableness analysis depends on whether the request is "job-related and consistent with business necessity," which means HR should be able to articulate why they need it.

If the explanation is unsatisfactory or if HR refuses to explain, you can decline to provide additional documentation while expressing willingness to engage in interactive process discussion. This is a place where consulting an employment attorney is worth the time.

How to renew a letter cleanly

If you're renewing because the original duration has elapsed or your situation has changed, the process is similar to the original evaluation but usually faster.

Gather your previous documentation. Bring the original letter to your renewal appointment. The new clinician should have visibility into what was previously documented.

Document any changes. Note any new symptoms, changes in treatment, changes in job duties, or accommodation effectiveness. If the original accommodation has been working well, that's relevant context for the new letter.

Confirm continued condition. A renewal letter should affirm that the underlying condition continues to substantially limit major life activities and that the accommodation continues to be necessary.

Update the duration. A renewal letter typically extends the recommended duration with the same "indefinite with periodic review" language or sets a new specific period.

What if my employer is using "renewal" as a backdoor denial?

A pattern we sometimes see: an employee has a stable, well-functioning accommodation. A new manager comes in, decides they don't want the arrangement, and asks HR to "review" the accommodation. HR sends a letter requesting updated documentation. The employee complies. The employer then says "thank you, we'll review this," and weeks later denies the renewal.

This isn't supposed to happen. If you've had an accommodation in place and there's no underlying change in your condition or job, a properly framed renewal letter should be enough to maintain it. Denials at this stage usually involve some combination of the employer claiming undue hardship, claiming an alternative accommodation would be equally effective, or claiming the condition no longer substantially limits major life activities.

If you receive a denial after a renewal request, our piece on what to do when your accommodation request is denied walks through the next steps. The EEOC's charge filing process is available, and the legal protections against retaliation apply throughout.

A note on FMLA recertification

If your accommodation is tied to FMLA leave (intermittent leave for episode flares, for example), the FMLA has specific recertification rules that are different from ADA documentation rules. Employers can require recertification no more frequently than every 30 days in connection with an absence, no more often than every 6 months for chronic conditions, or sooner if circumstances change significantly. These FMLA rules don't apply to pure ADA accommodation requests, only to leave certifications.

Practical next step

If your accommodation has been in place for a year or more and HR has begun asking for updates, treat the request seriously and respond promptly with current documentation. If your original provider isn't available or isn't a good fit for the renewal, you can use a different qualified provider. The Standard Evaluation at $169 covers a renewal letter, and the Complete Support package at $299 is appropriate if HR is sending multiple forms with the renewal request. If you've booked with us previously, you can use our renewal service at a discount.

If you've been wondering whether your existing letter is at risk of being challenged, you can also use a renewal evaluation as a proactive move. A current letter with strong documentation language is harder for an employer to push back on than an aging letter with vague duration.

This is general information, not legal advice. Renewal situations have nuance based on jurisdiction, employer size, and specific circumstances. For advice on your situation, consult an employment attorney.
