ADA Accommodation Letter from Therapist: Template & Guide

What Is an ADA Accommodation Letter?

An ADA accommodation letter is a clinical document written by a treating mental health professional to support a client's request for a reasonable workplace accommodation under the Americans with Disabilities Act (ADA). The letter provides the employer with the clinical documentation needed to verify that the employee has a qualifying condition and that the requested accommodation is related to that condition.

Under the ADA, employers with 15 or more employees are required to provide reasonable accommodations to qualified employees with disabilities, unless the accommodation would pose an undue hardship on the employer. A reasonable accommodation is any modification to the job, work environment, or the way work is performed that enables the employee to perform the essential functions of their position. For mental health conditions, common accommodations include flexible scheduling, the ability to work from home on high-symptom days, a quieter workspace, modified break schedules, temporary reduction in workload, and leave for therapy appointments.

The therapist's role in this process is to document the clinical basis for the accommodation — not to negotiate with the employer or determine what specific accommodation the employer must provide. Your letter establishes that there is a disability-related need and connects it to the functional limitations that the accommodation would address. The employer and employee then engage in the "interactive process" to determine the specific accommodation.

When You Need It

• When a client needs to request a workplace accommodation through their employer's HR department
• When an employer requests medical documentation to evaluate an accommodation request
• When a client is struggling at work due to mental health symptoms and needs modifications to maintain their employment
• When a client has an existing accommodation that needs to be renewed or modified
• When a client is returning to work after a leave of absence and needs transitional accommodations

Key Components

Your credentials and relationship to the client. State your name, license type, license number, and confirm that the client is under your active care. Include the duration of the therapeutic relationship. Employers may verify that the documentation comes from a qualified professional.

Statement of qualifying condition. Confirm that the client has a condition that constitutes a disability under the ADA — a mental health impairment that substantially limits one or more major life activities. As noted above, you generally should not disclose the specific diagnosis unless the client consents and it serves a clear purpose.

Functional limitations. This is the most important section. Describe the specific functional limitations the client experiences in the workplace context. Be concrete — do not simply say "the client has difficulty at work." Explain which major life activities or job functions are affected and how. For example: difficulty sustaining concentration for extended periods, difficulty managing acute stress responses, or difficulty maintaining a consistent sleep schedule that affects morning alertness.

Connection between limitations and accommodation. Explain how the requested accommodation addresses the functional limitations you have described. The employer needs to understand that there is a logical link between the condition, the limitation, and the specific modification being requested.

Expected duration. Indicate whether the accommodation is expected to be temporary or ongoing, and when it should be reviewed. If the client's condition is likely to improve with treatment, note this and suggest a review timeline.

What to leave out. Do not include session content, therapy details, trauma history, medication names or dosages (unless directly relevant to a specific limitation like medication side effects), or any information beyond what is necessary to support the accommodation request. The principle of minimum necessary disclosure applies.

How to Write It Step by Step

Step 1: Discuss the request thoroughly with your client. Before writing, understand what the client is experiencing at work, what accommodation they believe would help, and what information they are comfortable having shared with their employer. Review the principle of minimum necessary disclosure — you will share only what is needed to support the request.

Step 2: Assess whether the request is clinically supported. Determine whether the client's condition meets the ADA disability threshold and whether the requested accommodation has a logical connection to their functional limitations. If a client requests an accommodation that does not align with their clinical presentation, discuss this honestly and explore alternatives.

Step 3: Frame limitations functionally, not diagnostically. Employers do not need to know the client's diagnosis — they need to understand the functional impact. Translate clinical symptoms into workplace-relevant language. Instead of "client experiences panic attacks," write "client periodically experiences acute physiological distress episodes that temporarily impair concentration." This provides the information the employer needs without disclosing clinical details.

Step 4: Connect each limitation to a specific accommodation. The letter should make the logic clear: this limitation exists, this accommodation addresses it, and here is why. Avoid requesting accommodations that are not connected to a documented limitation, as this weakens the credibility of the entire request.

Step 5: Be specific about the accommodations. "Flexible schedule" is vague. "Adjusted start time from 8:00 AM to 9:30 or 10:00 AM" is specific and actionable. The more specific your recommendation, the easier it is for the employer to implement and the harder it is to dismiss as unreasonable.

Step 6: Include a duration and review timeline. Employers are more receptive to accommodations that include a review period. Even if the accommodation may be needed long-term, framing it with an initial period and a review date demonstrates that it is being managed actively.

Step 7: Offer to participate in the interactive process. The ADA requires employers to engage in an interactive process with the employee to identify effective accommodations. Offering to provide additional information or participate in that process signals that your recommendation is grounded in clinical expertise and that you are available for follow-up.

Step 8: Document the letter in your clinical record. Note that the client requested the letter, what information was included, that you discussed the content with the client, and the date the letter was issued. This protects both you and the client.

Common Mistakes

1. Over-disclosing clinical information. This is the most common error. Including the client's diagnosis, medication list, trauma history, or therapy content provides far more information than the employer needs and violates the principle of minimum necessary disclosure. Stick to functional limitations and the connection to the accommodation.

2. Writing vague limitation descriptions. "Client has difficulty at work due to anxiety" is not actionable for an employer. Describe the specific functional impact — what tasks are affected, when the limitations are most pronounced, and how they manifest in the workplace context.

3. Requesting accommodations without clinical justification. Every accommodation you recommend should be clearly tied to a documented functional limitation. If you request a flexible schedule but have not described a sleep or timing-related limitation, the employer has no basis for understanding why the accommodation is needed.

4. Positioning the letter as a demand rather than clinical documentation. Your role is to provide clinical support for the accommodation request, not to tell the employer what they must do. Use language like "I recommend" and "this accommodation would address" rather than "the employer must provide." The interactive process determines the final outcome.

5. Failing to include a review period. Open-ended accommodation requests can create resistance from employers. Including a review timeline — even for conditions that are likely to require ongoing accommodations — demonstrates that the situation is being actively managed and monitored.

Ethical Considerations

Writing accommodation letters requires balancing your role as a client advocate with your professional obligations. You are not a forensic evaluator — you are a treating clinician providing documentation based on your clinical knowledge. This distinction matters.

Stay within your clinical knowledge. Your letter should reflect what you have observed and assessed in the course of treatment. Do not make claims about the client's workplace performance that you have not clinically verified. You can describe functional limitations as they present in treatment and as the client reports them, but you should not represent yourself as having direct knowledge of the client's work environment.

Do not exaggerate limitations. If the client's condition genuinely warrants an accommodation, an honest description of their limitations will be sufficient. Exaggerating limitations to strengthen the request undermines your credibility and violates ethical standards regarding truthfulness in professional statements (APA Ethics Code Standard 5.01).

Respect the client's autonomy. Some clients may want you to include the diagnosis; others may not. Discuss the content of the letter with the client before writing it and respect their preferences about what information is shared. The client may also decide not to pursue the accommodation after learning what disclosure is involved — that is their right.

Maintain role boundaries. You are the treating therapist, not the client's employment advocate or attorney. Provide clinical documentation and let the client, their HR department, and if necessary their legal counsel navigate the accommodation process. If the accommodation request becomes adversarial, the client may benefit from consulting an employment attorney, and you should maintain your clinical role rather than becoming drawn into a workplace dispute.
