29 CFR Part 1630, Regulations to Implement the Equal Employment Provisions of the ADA (Title I Regulations with amendments issued through May 2016)

(j) Substantially limits—

(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) An impairment is a disability within the meaning of this section 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 need not 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.

(iii) The primary object of attention in cases brought under the ADA should be whether covered entities have complied with their obligations and whether discrimination has occurred, not whether 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.

(iv) 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 ADAAA.

(v) 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 analysis. Nothing in this paragraph is intended, however, to prohibit the presentation of scientific, medical, or statistical evidence to make such a comparison where appropriate.

(vi) 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.

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

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

(ix) The six-month “transitory” part of the “transitory and minor” exception to “regarded as” coverage in §1630.15(f) does not apply to the definition of “disability” under paragraphs (g)(1)(i) (the “actual disability” prong) or (g)(1)(ii) (the “record of” prong) of this section. The effects of an impairment lasting or expected to last fewer than six months can be substantially limiting within the meaning of this section.

(2) Non-applicability to the “regarded as” prong. Whether an individual's impairment “substantially limits” a major life activity is not relevant to coverage under paragraph (g)(1)(iii) (the “regarded as” prong) of this section.

(3) Predictable assessments—

(i) The principles set forth in paragraphs (j)(1)(i) through (ix) of this section are intended to provide for more generous coverage and application of the ADA's prohibition on discrimination through a framework that is predictable, consistent, and workable for all individuals and entities with rights and responsibilities under the ADA as amended.

(ii) Applying the principles set forth in paragraphs (j)(1)(i) through (ix) of this section, the individualized assessment of some types of impairments will, in virtually all cases, result in a determination of coverage under paragraphs (g)(1)(i) (the “actual disability” prong) or (g)(1)(ii) (the “record of” prong) of this section. Given their inherent nature, these types of impairments will, as a factual matter, virtually always be found to impose a substantial limitation on a major life activity. Therefore, with respect to these types of impairments, the necessary individualized assessment should be particularly simple and straightforward.

(iii) For example, applying the principles set forth in paragraphs (j)(1)(i) through (ix) of this section, it should easily be concluded that the following types of impairments will, at a minimum, substantially limit the major life activities indicated: Deafness substantially limits hearing; blindness substantially limits seeing; an intellectual disability (formerly termed mental retardation) substantially limits brain function; partially or completely missing limbs or mobility impairments requiring the use of a wheelchair substantially limit musculoskeletal function; autism substantially limits brain function; cancer substantially limits normal cell growth; cerebral palsy substantially limits brain function; diabetes substantially limits endocrine function; epilepsy substantially limits neurological function; Human Immunodeficiency Virus (HIV) infection substantially limits immune function; multiple sclerosis substantially limits neurological function; muscular dystrophy substantially limits neurological function; and major depressive disorder, bipolar disorder, post-traumatic stress disorder, obsessive compulsive disorder, and schizophrenia substantially limit brain function. The types of impairments described in this section may substantially limit additional major life activities not explicitly listed above.

(4) Condition, manner, or duration—

(i) At all times taking into account the principles in paragraphs (j)(1)(i) through (ix) of this section, in determining whether an individual is substantially limited in a major life activity, it may be useful in appropriate cases to consider, as compared to most people in the general population, the condition under which the individual performs the major life activity; the manner in which the individual performs the major life activity; and/or the duration of time it takes the individual to perform the major life activity, or for which the individual can perform the major life activity.

(ii) Consideration of facts such as condition, manner, or duration may include, among other things, consideration of the difficulty, effort, or time required to perform a major life activity; pain experienced when performing a major life activity; the length of time a major life activity can be performed; and/or the way an impairment affects the operation of a major bodily function. In addition, the non-ameliorative effects of mitigating measures, such as negative side effects of medication or burdens associated with following a particular treatment regimen, may be considered when determining whether an individual's impairment substantially limits a major life activity.

(iii) In determining whether an individual has a disability under the “actual disability” or “record of” prongs of the definition of disability, the focus is on how a major life activity is substantially limited, and not on what outcomes an individual can achieve. For example, someone with a learning disability may achieve a high level of academic success, but may nevertheless be substantially limited in the major life activity of learning because of the additional time or effort he or she must spend to read, write, or learn compared to most people in the general population.

(iv) Given the rules of construction set forth in paragraphs (j)(1)(i) through (ix) of this section, it may often be unnecessary to conduct an analysis involving most or all of these types of facts. This is particularly true with respect to impairments such as those described in paragraph (j)(3)(iii) of this section, which by their inherent nature should be easily found to impose a substantial limitation on a major life activity, and for which the individualized assessment should be particularly simple and straightforward.

(5) Examples of mitigating measures—Mitigating measures include, but are not limited to:

(i) Medication, medical supplies, equipment, or appliances, low-vision devices (defined as devices that magnify, enhance, or otherwise augment a visual image, but not including ordinary eyeglasses or contact lenses), prosthetics including limbs and devices, hearing aid(s) and cochlear implant(s) or other implantable hearing devices, mobility devices, and oxygen therapy equipment and supplies;

(ii) Use of assistive technology;

(iii) Reasonable accommodations or “auxiliary aids or services” (as defined by 42 U.S.C. 12103(1));

(iv) Learned behavioral or adaptive neurological modifications; or

(v) Psychotherapy, behavioral therapy, or physical therapy.

(6) Ordinary eyeglasses or contact lenses—defined. Ordinary eyeglasses or contact lenses are lenses that are intended to fully correct visual acuity or to eliminate refractive error.
