Section 504 of the Rehabilitation Act of 1973, Pub. L. No. 93-112, 87 Stat. 394 (Sept. 26, 1973), codified at 29 U.S.C. § 701 et seq., is American legislation that guarantees certain rights to people with disabilities. It was one of the first U.S. federal civil rights laws offering protection for people with disabilities. It set precedents for subsequent legislation for people with disabilities, including the Virginians with Disabilities Act in 1985 and the Americans with Disabilities Act in 1990.
Section 504 states (in part):
No otherwise qualified individual with a disability in the United States, as defined in section 705(20) of this title, shall, solely by reason of her or his disability, be excluded from the participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving federal financial assistance or under any program or activity conducted by any Executive agency or by the United States Postal Service.
It is codified as 29 U.S.C. 794.
As amended in 1974, Section 111, Pub L. 93-516, 88 Stat. 1619 (Dec. 7, 1974), Individuals with Disabilities are:
Any person who (a) has a physical or mental impairment which substantially limits one or more of such person's major life activities, (b) has a record of such an impairment, or (c) is regarded as having such an impairment
where
Major life activities include caring for one's self, walking, seeing, hearing, speaking, breathing, working, performing manual tasks, and learning.
However, "For purposes of employment", Qualified Individuals with Disabilities must also meet "normal and essential eligibility requirements", such that:
For purposes of employment, Qualified Individuals with Disabilities are persons who, with Reasonable Accommodation, can perform the essential functions of the job for which they have applied or have been hired to perform.
where
Reasonable Accommodation means an employer is required to take reasonable steps to accommodate [one's] disability unless it would cause the employer undue hardship.
That is, Qualified Individuals with Disabilities must be able to perform the job duties associated with the job for which they would be hired. The USA Department of Labor also indicates that "Small Providers" do not have to make "significant structural alterations to their existing facilities" to accommodate the individual with the disability.
