Key Facts
- Federal level: The ADA requires covered employers to provide reasonable accommodation to qualified applicants and employees with disabilities unless doing so would impose undue hardship.
- Federal level: ADA accommodations may address the application process, essential job functions, or equal access to employment benefits and privileges.
- Federal level: Title VII separately requires reasonable accommodation of religious observance and practice unless the employer shows substantial increased costs in relation to its particular business.
- Federal level: The ADA and Title VII use different statutes and undue-hardship standards, so their accommodation rules are not interchangeable.
- General context: State and local laws may provide separate protections and require independent review.
Reasonable accommodation is a federal employment-law concept with more than one meaning. The two principal frameworks concern disability under the Americans with Disabilities Act and religion under Title VII of the Civil Rights Act of 1964.
ADA accommodation removes disability-related workplace barriers
Title I of the ADA applies to covered employment and prohibits discrimination against a qualified individual on the basis of disability. Discrimination includes failing to make reasonable accommodations to known physical or mental limitations unless the covered entity demonstrates undue hardship.
A qualified individual must satisfy the job-related prerequisites and be able to perform the position’s essential functions with or without accommodation. The ADA does not require removal of an essential function, although it may require changes to how or when the function is performed.
Possible accommodations include accessible facilities, modified equipment, readers or interpreters, schedule changes, leave, policy modifications, job restructuring of marginal duties, and reassignment to a vacant position. Whether an option is reasonable and effective depends on the position and the barrier involved.
The interactive process develops information
A request can use ordinary language and need not cite the ADA or say “reasonable accommodation.” It must communicate that a work change is needed for a reason related to a medical condition.
When the disability or effective accommodation is not obvious, the federal regulation describes an informal, interactive process to identify the person’s precise limitations and potential accommodations. Limited documentation may be appropriate when needed to establish a covered disability and the accommodation-related functional limitation.
The process does not guarantee the employee’s preferred option. An employer may select another effective accommodation, while an ineffective change does not satisfy the purpose of providing equal employment opportunity.
ADA undue hardship means significant difficulty or expense
The ADA defines undue hardship as significant difficulty or expense when considered in light of statutory factors, including cost, resources, facility structure, workforce size, and operational effect. The analysis concerns the particular accommodation and covered entity rather than a fixed dollar threshold.
The direct-threat rule is distinct. A qualification standard may address a significant risk of substantial harm that cannot be eliminated or reduced by reasonable accommodation, based on an individualized assessment using reasonable medical judgment and current medical knowledge or the best available objective evidence.
Religious accommodation comes from Title VII
Title VII’s definition of religion includes religious observance and practice as well as belief unless an employer demonstrates that it cannot reasonably accommodate the observance or practice without undue hardship on its business. Accommodations can involve schedules, voluntary swaps, dress or grooming practices, or other work rules.
In Groff v. DeJoy, the Supreme Court held in 2023 that Title VII undue hardship requires substantially increased costs in relation to the conduct of the employer’s particular business. The Court rejected treating every cost greater than a minimal amount as sufficient.
Groff also explained that effects on coworkers matter only to the extent they affect the conduct of the business, and that hostility to a religious practice cannot be counted as undue hardship. The analysis must consider reasonable options rather than assume that one proposed accommodation is the only possibility.
The two frameworks should remain separate
ADA undue hardship expressly means significant difficulty or expense and uses listed statutory factors. Title VII religious undue hardship follows Groff’s substantial-increased-cost formulation, so borrowing one statute’s shorthand for the other can distort the analysis.
The ADA also contains disability-specific concepts such as essential functions, qualified individual, medical-information limits, and direct threat. A related ADA accommodation overview can deepen that disability framework, while a Title VII overview explains the separate civil-rights statute.
Federal law supplies nationwide standards, but it does not establish that every requested change is required. Coverage, qualification, notice, effectiveness, hardship, safety, and other governing rules remain distinct legal questions, and state or local law may add separate protections.
