28 CFR 42.511 - Reasonable accommodation.
(a) A recipient shall make reasonable accommodation to the known physical or mental limitations of an otherwise qualified handicapped applicant or employee unless the recipient can demonstrate, based on the individual assessment of the applicant or employee, that the accommodation would impose an undue hardship on the operation of its program or activity.
(b) Reasonable accommodation may include making facilities used by employees readily accessible to and usable by handicapped persons, job restructuring, part-time or modified work schedules, acquisition or modification of equipment or devices (e.g., telecommunication or other telephone devices), the provisions of readers or qualified interpreters, and other similar actions.
(c) Whether an accommodation would impose an undue hardship on the operation of a recipient's program or activity depends upon a case-by-case analysis weighing factors that 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 workforce; and
(3) The nature and cost of the accommodation needed.
