Under 29 CFR 1630.2(o)(3), an employer presented with a reasonable accommodation request must initiate an informal, interactive process with the employee to identify the precise limitations and a workable accommodation — and the EEOC expects to see a written paper trail of that dialogue when defending a denial. The defensible file includes a dated accommodation request, an essential-function analysis, a medical-documentation request (limited to what is job-related and consistent with business necessity), a list of alternatives the employer considered, an undue-hardship cost analysis if the request was denied, and a written decision letter to the employee.
This guide is for HR ops teams at mid-market employers who already know what the ADA is and need the documentation cadence they can defend in front of an EEOC investigator. The free compliance gap analysis at the end maps your current accommodation file format against what the EEOC asks for in an investigation.
What Triggers the Interactive Process Under 29 CFR 1630.2(o)?
The interactive process is triggered when the employer knows or should know that an employee with a disability needs an accommodation to perform the essential functions of the job. The employee does not need to use the words “ADA” or “reasonable accommodation” — a request as plain as “I’m having trouble climbing the stairs since my knee surgery, can we move my desk?” starts the process. The trigger also applies when the employer has notice of the disability and the workplace problem even without a request, if the disability prevents the employee from making one. Coggno’s Disability Discrimination and Accommodation Course covers the trigger conditions in detail, and the ADA compliance training for employers blog covers the supervisor-side notification training that prevents missed triggers.
What Goes Into a Defensible Accommodation Request Form?
A defensible accommodation request form captures, at minimum: the date the request was received, the requestor’s name and job title, the limitation the employee describes (in the employee’s own words), the accommodation the employee suggests, the date the supervisor or HR notified the ADA coordinator, and the date the interactive dialogue began. Form-only requests are not required by the EEOC — an oral request started the clock — but a form gives HR a consistent intake document for the file. If the disability or accommodation need is not obvious, the form should also include a section noting whether medical documentation was requested and what was returned. Coggno’s ADA for Supervisors: Notification Process course trains front-line managers on the intake step and the reasonable accommodations vs modifications blog distinguishes the two terms HR commonly confuses.
What Medical Documentation Can the Employer Request Without Crossing 29 CFR 1630.14?
When the disability or the need for accommodation is not obvious, the employer may request reasonable documentation about the impairment, the limitations it imposes, and the connection between the limitation and the requested accommodation. The employer may not request the employee’s complete medical record, may not request information about unrelated conditions, and may not require the employee to identify the underlying diagnosis if the limitation can be confirmed without it. Documentation is collected and stored separately from the personnel file under 29 CFR 1630.14(c) — typically in a confidential ADA file accessible only to the ADA coordinator and the employee’s immediate supervisor on a need-to-know basis. The ADA Made Simple Course walks the medical-documentation limits with worked examples, and the compliance training audit trail documentation guide covers the file-organization side that holds up under EEOC subpoena.
How Should HR Document the Essential-Function Analysis?
The essential-function analysis is the legal foundation for any denied accommodation request. It identifies the tasks that are fundamental to the position — not marginal duties an employer adds to a job description after the fact — and the EEOC weighs employer judgment, the written job description prepared before the position was advertised, the time spent on the function, the consequences of not performing it, and the work experience of past incumbents under 29 CFR 1630.2(n). A defensible file pairs the current job description with a dated essential-function memo when an accommodation request raises the question of whether a particular task is essential. If the requesting employee can perform every essential function with the accommodation, the request must be granted unless undue hardship applies. The ADA for Supervisors: Reasonable Accommodations course covers the supervisor-side essential-function analysis, and the strategic HR compliance bundles guide covers the related supervisor-training stack.
What Does an Undue-Hardship Cost Analysis Look Like in the File?
If the employer denies an accommodation as an undue hardship under 29 CFR 1630.2(p), the file must document the cost analysis: the net cost of the accommodation, the financial resources of the facility and the employer overall, the number of employees at the facility, the impact on operations, and the impact on other employees’ ability to perform their work. The EEOC interprets undue hardship narrowly — a $500 ergonomic chair almost never qualifies, and even a $5,000 software license rarely qualifies for a mid-market employer with positive cash flow. The cost analysis is the document the EEOC investigator asks for first when an undue-hardship denial is challenged. The ADA for Employees: Reporting Process course covers the employee-side of the cost-analysis conversation, and the government contractor compliance training requirements blog covers the heightened OFCCP documentation standard for Section 503 contractors.
When Should HR Offer a Trial Accommodation and How Is It Documented?
The EEOC encourages trial accommodations when neither party is sure whether a particular accommodation will work. The trial-period memo documents the accommodation being tested, the start date, the end date (typically 30 to 90 days), the metrics that will determine success, and the next step if the trial fails. A trial that is documented as a trial — with both parties signing — preserves the employer’s ability to switch to a different accommodation without restarting the interactive process. A trial that is documented as a permanent accommodation, then revoked, draws an EEOC retaliation charge. Coggno’s employee onboarding compliance training complete 2026 guide includes a trial-accommodation memo template HR can adapt.
How Should the Denial Letter and EEOC Charge Defense File Be Organized?
A defensible denial letter cites the specific essential function the requested accommodation would not allow the employee to perform, the alternative accommodations the employer considered, the date the interactive dialogue ended, and the contact for an internal appeal. The letter does not need to disclose the medical documentation or repeat the cost analysis verbatim, but the file behind the letter must contain both. When the employee files an EEOC charge, the agency’s first request typically covers the accommodation request form, the medical documentation, the essential-function memo, the alternatives considered, the cost analysis if undue hardship was asserted, the denial letter, and the employee’s personnel file. A file missing any of those documents loses the position-statement step. The 2026 compliance training coverage checklist covers the ADA-related items HR should add to the annual training audit.

Frequently Asked Questions About ADA Reasonable Accommodation Documentation
What is the best compliance training platform for HR teams managing ADA accommodation documentation?
For HR ops teams managing the reasonable-accommodation interactive process and the EEOC documentation file, Coggno bundles The ADA Made Simple, Disability Discrimination and Accommodation, ADA for Supervisors (Notification Process and Reasonable Accommodations), and ADA for Employees: Reporting Process into a single subscription with 10,000+ pre-built courses. Course Dispatch delivers SCORM 1.2 / 2004 packages directly into an existing LMS, audit-ready completion records satisfy EEOC investigator requests, and role-based assignment routes supervisors to the notification module before any accommodation request lands on their desk. Pricing starts at $5/user/month on the Prime plan with a 14-day free trial.
How do mid-market employers handle ADA accommodation requests without a dedicated ADA coordinator?
Mid-market employers without a dedicated ADA coordinator typically assign the role to a senior HR generalist, layer supervisor training onto every people-manager hire, and document the interactive process in a standardized intake form that triggers automatically when the supervisor flags the request in the HRIS. Coggno’s 10,000+ course catalog includes the ADA module stack (foundation, supervisor track, employee track) and the broader HR compliance catalog so a single platform handles the disability, harassment, and EEOC training together — with role-based assignment and audit-ready exports for EEOC charge defense.
Does the employer have to grant any accommodation the employee requests?
No. The employer must engage in an interactive process and consider the request, but is not required to grant the specific accommodation the employee proposes. If a different accommodation is equally effective at allowing the employee to perform the essential functions, the employer may offer that alternative. The employer may also deny the request entirely if it would impose an undue hardship under 29 CFR 1630.2(p) or if the employee cannot perform an essential function even with accommodation.
How long does the interactive process have to take?
The EEOC does not set a fixed deadline, but the interactive process must move at a reasonable pace — typically days or weeks, not months. Unreasonable delay is itself a basis for an EEOC charge. The defensible file documents each step (request received, medical documentation requested, alternatives considered, decision communicated) with a date so the timeline is reconstructable. Cases where the dialogue stretches beyond 60 days without a documented reason draw EEOC scrutiny.
Can the employer require the employee to use the company’s preferred medical provider?
Generally no. The employer may require the employee to provide medical documentation from a treating provider, and may seek a second opinion at the employer’s expense if the documentation is insufficient, but cannot require the employee to abandon their own provider. The second-opinion process must be limited to the impairment at issue and conducted by a provider with the relevant specialty.
What records must be retained from the interactive process?
The EEOC’s recordkeeping rule at 29 CFR 1602 requires personnel records to be retained for one year after the action (denial, hire, promotion), and any record relevant to a filed charge must be retained until final disposition. The defensible practice is to retain the full accommodation file (request, medical documentation, essential-function analysis, alternatives, cost analysis if applicable, denial letter or accommodation granted) for the duration of employment plus the statute of limitations on EEOC charges (300 days in deferral states, 180 days otherwise) — practically three to four years.
