Work accommodations and ADA basics
How adults with ADHD, autism or another disability can ask for workplace accommodations, what documentation helps, and what employers must do.
Last reviewed November 5, 2026
The short version
- The ADA protects eligible employees with disabilities and requires reasonable accommodations.
- An accommodation is a change to the job or workplace that helps an employee perform essential functions.
- You do not have to disclose a diagnosis to ask for an accommodation, but you may need to explain the limitation.
- The employer and employee should use an interactive process to find a workable solution.
- Documentation from a provider can support the request without dictating the exact accommodation.
Work can be a good fit on paper and still be exhausting in practice. Small changes, such as written instructions, a quieter space or a flexible start time, can make a real difference. The ADA gives eligible employees a right to ask for those changes.
This guide explains the basics. It is general information, not legal advice.
What the ADA covers
The Americans with Disabilities Act protects qualified employees with disabilities from discrimination and requires employers to provide reasonable accommodations. A disability is a physical or mental impairment that substantially limits a major life activity, a record of such an impairment, or being regarded as having one.
The ADA applies to employers with 15 or more employees. Texas law and local rules may cover others, and some employers have policies that go further.
What an accommodation is
An accommodation is a change to the application process, the work environment or the way a job is performed. Examples:
- A quiet workspace or noise-canceling headphones
- Written instructions and checklists
- Flexible start or end times
- Breaks during the day
- A modified schedule or reduced hours
- Assistive technology or software
- Clear expectations and regular feedback
- Time off for appointments or treatment
- A support animal, in some situations
An accommodation does not have to be the employee’s first-choice option, but it should be effective.
Do I have to disclose?
You do not have to tell an employer about a diagnosis unless you want an accommodation or ADA protection. You can describe the limitation and the support you need without sharing every detail.
For example: “I have a condition that affects my ability to concentrate in a noisy open office. I’d like to discuss a quieter workspace or noise-canceling headphones.”
The interactive process
The employer and employee should talk about:
- The essential functions of the job
- The limitation and how it affects work
- Possible accommodations
- Whether an accommodation would create undue hardship
The process should be timely and individualized. An employer can ask for reasonable documentation, but it should be limited to what is relevant.
Documentation that helps
A provider letter can support the request. It should:
- Confirm that the person has a condition that affects a major life activity
- Describe the functional limitations
- Suggest accommodations when appropriate
- Avoid disclosing more medical detail than necessary
A letter is not a prescription for one specific accommodation. The employer and employee still need to find a workable solution.
If a request is denied
Ask for the reason in writing and whether another accommodation would work. You can contact the Equal Employment Opportunity Commission or a disability rights organization for guidance. Deadlines apply, so do not wait.

Questions and answers
The basics
What is a reasonable accommodation?
A reasonable accommodation is a change to the application process, work environment or how a job is performed that helps a qualified employee with a disability. Examples include a quiet workspace, written instructions, flexible scheduling or assistive technology.
Does the ADA apply to every employer?
The ADA applies to employers with 15 or more employees. Texas law and local rules may cover others. Some employers have their own policies that go further.
Do I have to tell my employer I have a disability?
Only if you want an accommodation or protection under the ADA. You can disclose the limitation and the support you need without sharing every diagnosis.
Can my employer ask for medical documentation?
An employer may ask for reasonable documentation that confirms a disability and the need for an accommodation. It should be limited to what is relevant and kept confidential.
Asking
How do I ask for an accommodation?
Put the request in writing, describe the limitation and the support you need, and ask to discuss options. Keep a copy. You do not need a specific script, but clarity helps.
What is the interactive process?
It is the conversation between employee and employer about the limitation, the essential functions of the job and possible accommodations. It should be timely and individualized.
Can my employer choose a different accommodation?
Yes, if it is effective and does not create undue hardship. The goal is a workable solution, not a specific product or schedule.
What if my request is denied?
Ask for the reason in writing and whether another accommodation would work. You can contact the Equal Employment Opportunity Commission or a disability rights organization for guidance.
Documentation
What should a provider letter say?
It should confirm that the person has a condition that affects a major life activity, describe the functional limitations and, when appropriate, suggest accommodations. It should not disclose more medical detail than necessary.
Can Fair Winds provide a letter?
If you are a current client, we can discuss a letter or form as part of your care. Paperwork is billed separately. We do not provide legal advice.
