Undue Burden

« Back to Glossary Index

Under the ADA, Undue burden means significant difficulty or expense. In determining whether an action would result in an undue burden, factors to be considered include –

(1) The nature and cost of the action needed under this part; (2) The overall financial resources of the site or sites involved in the action; the number of persons employed at the site; the effect on expenses and resources; legitimate safety requirements that are necessary for safe operation, including crime prevention measures; or the impact otherwise of the action upon the operation of the site; (3) The geographic separateness, and the administrative or fiscal relationship of the site or sites in question to any parent corporation or entity; (4) If applicable, the overall financial resources of any parent corporation or entity; the overall size of the parent corporation or entity with respect to the number of its employees; the number, type, and location of its facilities; and (5) If applicable, the type of operation or operations of any parent corporation or entity, including the composition, structure, and functions of the workforce of the parent corporation or entity.

An undue burden is a requirement of Title II or Title III of the Americans with Disabilities Act (ADA) that would cause a significant difficulty or expense if carried out. This means that a state or local government or its agencies, or a business or nonprofit organization covered by the ADA, does not have to provide an auxiliary aid or service, or a modification, if providing it would cause a significant administrative or financial difficulty. Undue burden is similar to undue hardship under Title I (employment).

When deciding whether something is an undue burden, you have to look at several factors. These factors include the overall cost involved in light of the entire organization and any parent organization, and the operation and nature of the organization. If an auxiliary aid or service is an undue burden, the organization must look for an effective alternative. For example, if a small, private museum cannot afford to provide a sign language interpreter for a museum tour on short notice, a written copy of the tour guide’s script might be an alternative.
