The Americans with Disabilities Act is built on a simple premise: a qualified employee should not lose a job opportunity because of a disability that a reasonable adjustment could address. Reasonable accommodation is the mechanism that makes the premise operational. It's the set of changes an employer makes to a job, schedule, or workspace so the employee can perform the essential functions of the role. The ADA doesn't require employers to fundamentally alter the job or carry an undue financial hardship, but it does require a good-faith process to figure out what works. Missteps in that process generate a substantial share of EEOC charges each year.
The ADA Interactive Process Explained When an employee discloses a disability and requests accommodation, the employer has to engage in what the ADA calls the interactive process. The employee describes the limitation and the need; the employer explores what adjustments might work, what limitations exist, and what essential functions of the role must be preserved. The conversation usually involves medical documentation (limited to what's necessary to evaluate the request) and input from the employee on what has worked in the past.
The process is iterative, not a single yes-or-no decision. If the first proposed accommodation doesn't work or creates an undue hardship, the employer owes continued engagement to find an alternative. Breaking off the conversation prematurely, or insisting on a specific accommodation when effective alternatives exist, is how employers end up on the wrong side of an ADA claim.
What Counts as a Reasonable Accommodation? The EEOC lists common categories: modifications to work schedules (flexible hours, part-time schedules, leave for treatment), changes to the physical workspace (accessibility features, ergonomic equipment, reserved parking), provision of assistive technology or adaptive devices (screen readers, captioning, specialized software), and job restructuring (reassigning marginal functions, changing how essential functions get performed).
Reassignment to a vacant position is an accommodation of last resort when the current role can't be accommodated. The employee has to be qualified for the alternative role, and the employer has to identify genuinely vacant positions rather than require the employee to compete on equal terms with external candidates.
Does Remote Work Count as a Reasonable Accommodation? Sometimes. The analysis turns on whether the essential functions of the role can be performed remotely. After 2020, most knowledge work demonstrated it can, which has raised the bar for employers claiming in-person presence is essential. A blanket "we require everyone to be in the office" position rarely survives an ADA challenge if comparable roles have been performed remotely in the past.
When Can an Employer Say No? The Undue Hardship Standard Undue hardship means significant difficulty or expense, evaluated against the employer's size, budget, and operation. The cost of the accommodation is one factor but rarely the only one. For a Fortune 500 employer, a $5,000 accommodation almost never crosses the undue hardship threshold. For a 20-person business, the same accommodation might.
Operational disruption can support an undue hardship claim, but courts look closely at the specifics. Generalized arguments ("it would be hard to manage") typically fail. Specific documented impact ("this would require restructuring the entire shift pattern for 40 employees") can succeed.
Running a Reasonable Accommodation Process That Holds Up Four practices separate employers that get ADA accommodations right from those that end up in EEOC litigation. First, a documented intake process: every accommodation request gets logged, assigned to a trained owner, and tracked from intake to resolution. Second, a standard interactive process template: the conversation covers the same ground for every request, with documented proposals and responses. Third, manager training: frontline managers are the people who usually receive the initial request, and they need to know what to do instead of reflexively saying no. Fourth, links to job descriptions that clearly distinguish essential functions from marginal ones, which is the starting point for any accommodation analysis.
For federal guidance, the EEOC enforcement guidance on reasonable accommodation is the most detailed reference, and the Job Accommodation Network (a DOL-funded resource) maintains a searchable database of accommodation ideas by condition and occupation that most HR teams find useful.
