Under California law, reasonable accommodation and the interactive process work as a pair. Employers with five or more employees must accommodate a known disability unless doing so would cause undue hardship, and they must engage in a timely, good-faith interactive process to find that accommodation.
California treats a failure in either step as its own violation, which is why these claims show up in so many employment lawsuits. This guide explains when the duty starts, how to run the process step by step, what you can ask for, and how to document each step so the file holds up later.
What Is the Interactive Process in California?
The interactive process is a good-faith, two-way conversation between an employer and an applicant or employee to identify an effective accommodation for a disability. California's Fair Employment and Housing Act (FEHA), the state anti-discrimination law enforced by the Civil Rights Department (CRD, formerly DFEH), requires it under Government Code Section 12940(n).
Two separate duties apply. Government Code Section 12940(m) requires reasonable accommodation, and Section 12940(n) requires the interactive process itself, so an employer can face a claim for skipping the process even when it had legitimate concerns about the request.
FEHA reaches further than the federal Americans with Disabilities Act (ADA), which applies only at 15 or more employees. Here is how the two compare.
| Federal ADA | California FEHA |
|---|---|
| Applies to employers with 15 or more employees | Applies to employers with 5 or more employees |
| Disability must "substantially limit" a major life activity | Disability only needs to "limit" a major life activity |
| Interactive process expected under guidance | Failure to engage is a separate statutory violation |
| Compensatory and punitive damages are capped | No statutory cap on damages in court |
When Does an Employer Have to Start the Interactive Process?
Under California Code of Regulations, Title 2, Section 11069, the duty starts in more situations than most managers expect. You must begin or offer the interactive process when any of the following happens.
- An applicant or employee with a known disability asks for an accommodation
- You become aware of a possible need through a third party or your own observation
- An employee has used up CFRA, FMLA, or other leave and still needs accommodation
- A workers' compensation claim or doctor's note shows work restrictions
Employees do not need to use the words "accommodation" or "disability." A comment such as "my back can't handle the lifting anymore" can be enough to put you on notice.
That is why supervisors need one simple instruction. When an employee mentions a medical limitation, the supervisor reports it to HR the same day and does not decide anything alone, a point your California employee handbook requirements should also reflect.
How Should Employers Run the Interactive Process Step by Step?
There is no required form, but a consistent sequence protects you. Follow these steps for every request.
- Acknowledge the request promptly in writing and schedule a meeting.
- Identify the essential functions of the job using a current job description.
- Request reasonable medical documentation if the disability or need is not obvious.
- Meet with the employee to discuss limitations and possible accommodations, including the employee's own ideas.
- Consider each option, including the employee's preference, and research alternatives.
- Grant an effective accommodation, or explain why a specific request will not work and offer alternatives.
- Confirm the decision in writing and set a date to check whether it is working.
The process is ongoing. If an accommodation stops working or the employee's condition changes, the duty to engage starts again.
What Medical Documentation Can You Request?
When the disability or the need for accommodation is not obvious, you may ask for reasonable medical documentation confirming both. The regulations limit how far that request can go.
- You may ask for confirmation of the disability and the related limitations
- You may not ask for the employee's complete medical records
- You generally may not ask for the underlying diagnosis once you have reasonable documentation
- You must keep medical information confidential and separate from the personnel file
What Counts as a Reasonable Accommodation?
A reasonable accommodation is any change that lets a qualified employee perform the essential functions of the job. Common examples include the following.
- Modified schedules or part-time work
- Restructuring nonessential job duties
- Ergonomic equipment or assistive technology
- Remote work when the job allows it
- A finite leave of absence for treatment or recovery
- Reassignment to a vacant position the employee is qualified for
You may choose among effective options, so you do not have to provide the employee's first choice. You also do not have to eliminate essential functions, create a new position, or grant indefinite leave.
How Does Leave Work as a Reasonable Accommodation?
Leave is one of the most common accommodations and one of the most common sources of mistakes. California leave laws often stack, and FEHA can require additional leave after other leave runs out.
| Leave source | How it fits |
|---|---|
| CFRA (12 weeks) | Job-protected family and medical leave for employers with 5 or more employees |
| Pregnancy disability leave (up to 4 months) | Separate leave for pregnancy-related disability |
| Workers' compensation | Runs alongside other leave when the condition is work-related |
| FEHA accommodation leave | Additional finite leave when it would let the employee return to work |
Consider an Otay Mesa distribution company whose forklift operator returns from 12 weeks of CFRA leave after back surgery, with a 20-pound lifting restriction for two more months. Ending employment because CFRA ran out would invite a claim, while a temporary reassignment or a short extension of leave would likely satisfy FEHA.
When Can an Employer Deny a Requested Accommodation?
You can deny a specific accommodation when an effective alternative exists, or when the accommodation would cause undue hardship. Under Government Code Section 12926, undue hardship means significant difficulty or expense, measured against the employer's size, resources, and operations.
The employer carries the burden of proving undue hardship, and courts look closely at large employers. A denial should rest on documented facts, such as cost estimates or safety concerns, not assumptions about what the employee can do.
If the employee stops participating, document each attempt to continue the process. The regulations also recognize that an employee's own condition may prevent engagement, so patience and written follow-ups help.
Denials and terminations connected to a medical condition carry real exposure. FEHA allows emotional distress damages, punitive damages, and attorney fees, which is why many disability claims end up in wrongful termination defense for employers.
Which Interactive Process Mistakes Lead to Claims?
Most accommodation claims come from process gaps, not bad intentions. Watch for these patterns.
- Letting weeks pass before responding to a request
- Deciding over email without ever meeting the employee
- Rejecting a request without offering alternatives
- Asking for full medical records or a diagnosis
- Ending employment the day protected leave runs out
- Failing to document meetings and decisions
Accommodation requests are also protected activity, so any later discipline needs extra care. These steps on how to prevent retaliation claims apply directly to employees who have asked for help.
If a claim does arrive, it usually starts as an agency charge. Our guides on responding to a CRD complaint and what to expect if an EEOC charge follows explain the early steps.

Frequently Asked Questions
Which California employers must provide reasonable accommodation?
Employers with five or more employees must provide reasonable accommodation under FEHA. The Civil Rights Department's accommodation guidance explains the duty and lists common examples.
Can an employer ask for a doctor's note?
Yes, when the disability or the need for accommodation is not obvious. The note should confirm the disability and the need for accommodation, and the employer should not request complete medical records.
Does an employer have to give the employee the accommodation they ask for?
No. The employer must consider the employee's preference, but it may choose any effective accommodation, and the EEOC's guidance on reasonable accommodation and undue hardship takes the same position under federal law.
How long should the interactive process take?
No fixed deadline exists, but the process must be timely. Most employers should acknowledge a request within a few days and hold the first meeting soon after.
Is indefinite leave a reasonable accommodation in California?
No. FEHA can require a finite leave that is likely to let the employee return to work, but employers do not have to hold a job open indefinitely.
Do I need to accommodate an employee who never used the word disability?
Yes, if you know or should know about the limitation. Employees can put an employer on notice in plain language, and the employer must then offer the interactive process.
