29 C.F.R. § 1630.2
§ 1630.2 Definitions.
(1) The term reasonable accommodation means:
(i) Modifications or adjustments to a job application process that enable a qualified applicant with a disability to be considered for the position such qualified applicant desires; or
(ii) Modifications or adjustments to the work environment, or to the manner or circumstances under which the position held or desired is customarily performed, that enable an individual with a disability who is qualified to perform the essential functions of that position; or
(iii) Modifications or adjustments that enable a covered entity's employee with a disability to enjoy equal benefits and privileges of employment as are enjoyed by its other similarly situated employees without disabilities.
(2) Reasonable accommodation may include but is not limited to:
(i) Making existing facilities used by employees readily accessible to and usable by individuals with disabilities; and
(ii) Job restructuring; part-time or modified work schedules; reassignment to a vacant position; acquisition or modifications of equipment or devices; appropriate adjustment or modifications of examinations, training materials, or policies; the provision of qualified readers or interpreters; and other similar accommodations for individuals with disabilities.
(3) To determine the appropriate reasonable accommodation it may be necessary for the covered entity to initiate an informal, interactive process with the individual with a disability in need of the accommodation. This process should identify the precise limitations resulting from the disability and potential reasonable accommodations that could overcome those limitations.
(4) A covered entity is required, absent undue hardship, to provide a reasonable accommodation to an otherwise qualified individual who meets the definition of disability under the “actual disability” prong (paragraph (g)(1)(i) of this section), or “record of” prong (paragraph (g)(1)(ii) of this section), but is not required to provide a reasonable accommodation to an individual who meets the definition of disability solely under the “regarded as” prong (paragraph (g)(1)(iii) of this section).
