41 C.F.R. § 101-8.306

(a) A recipient shall make reasonable accommodation to the known physical or metal limitations of an otherwise qualified handicapped applicant or employee unless the recipient can demonstrate that the accommodation would impose an undue hardship on the operation of its program or activity.

(b) Reasonable accommodation may include:

(1) Making facilities used by employees readily accessible to and usable by handicapped persons; and

(2) Job restructuring; part-time or modified work schedules; acquisition or modification of equipment or devices, such as telecommunications devices or other telephonic devices for hearing impaired persons; provision of reader or qualified sign language interpreters; and other similar actions. These actions are to be taken either upon request of the handicapped employee or, if not so requested, upon the recipient's own initiative, after consultation with and approval by the handicapped person.

(c) In determining, under paragraph (a) of this section, whether an accommodation would impose an undue hardship on the operation of a recipient's program or activity, factors to be considered include:

(1) The overall size of the recipient's program or activity with respect to number of employees, number and type of facilities, and size of budget;

(2) The type of the recipient's operation, including the composition and structure of the recipient's work force; and

(3) The nature and cost of the accommodation needed.

(d) A recipient may not deny an employment opportunity to a qualified handicapped employee or applicant if the basis for the denial is the need to make reasonable accommodation to the physical or mental limitations of the employee or applicant.
