28 CFR Part 36 Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities (2010 ADA Title III Regulations with amendments issued through Dec. 2016)

(1) Rules of construction. The following rules of construction apply when determining whether an impairment substantially limits an individual in a major life activity.

(i) The term “substantially limits” shall be construed broadly in favor of expansive coverage, to the maximum extent permitted by the terms of the ADA. “Substantially limits” is not meant to be a demanding standard.

(ii) The primary object of attention in cases brought under title III of the ADA should be whether public accommodations have complied with their obligations and whether discrimination has occurred, not the extent to which an individual's impairment substantially limits a major life activity. Accordingly, the threshold issue of whether an impairment substantially limits a major life activity should not demand extensive analysis.

(iii) An impairment that substantially limits one major life activity does not need to limit other major life activities in order to be considered a substantially limiting impairment.

(iv) An impairment that is episodic or in remission is a disability if it would substantially limit a major life activity when active.

(v) An impairment is a disability within the meaning of this part if it substantially limits the ability of an individual to perform a major life activity as compared to most people in the general population. An impairment does not need to prevent, or significantly or severely restrict, the individual from performing a major life activity in order to be considered substantially limiting. Nonetheless, not every impairment will constitute a disability within the meaning of this section.

(vi) The determination of whether an impairment substantially limits a major life activity requires an individualized assessment. However, in making this assessment, the term “substantially limits” shall be interpreted and applied to require a degree of functional limitation that is lower than the standard for substantially limits applied prior to the ADA Amendments Act.

(vii) The comparison of an individual's performance of a major life activity to the performance of the same major life activity by most people in the general population usually will not require scientific, medical, or statistical evidence. Nothing in this paragraph (d)(1) is intended, however, to prohibit or limit the presentation of scientific, medical, or statistical evidence in making such a comparison where appropriate.

(viii) The determination of whether an impairment substantially limits a major life activity shall be made without regard to the ameliorative effects of mitigating measures. However, the ameliorative effects of ordinary eyeglasses or contact lenses shall be considered in determining whether an impairment substantially limits a major life activity. Ordinary eyeglasses or contact lenses are lenses that are intended to fully correct visual acuity or to eliminate refractive error.

(ix) The six-month “transitory” part of the “transitory and minor” exception in paragraph (f)(2) of this section does not apply to the “actual disability” or “record of” prongs of the definition of “disability.” The effects of an impairment lasting or expected to last less than six months can be substantially limiting within the meaning of this section for establishing an actual disability or a record of a disability.
