The San Francisco 504 sit-in, led in part by Heumann, ended after roughly 25-28 days—the longest occupation of a federal building in U.S. history.
Around April 28, 1977, the Section 504 sit-in at the San Francisco federal building concluded after nearly four weeks of continuous occupation by disabled activists, led in significant part by Judith Heumann. Sources vary slightly on the exact length—reporting 24 to 28 days—but it is universally recognized as the longest sit-in of a federal building in United States history.
Throughout the occupation, Heumann served as a key spokesperson and negotiator, testifying before officials and helping coordinate logistics for over one hundred activists with diverse disabilities living inside the building, many with significant medical and personal care needs. The sit-in demonstrated extraordinary solidarity across disability communities and drew support from labor unions, LGBTQ+ organizations, and civil rights groups.
The sustained pressure of the occupation, combined with a delegation of activists including Heumann traveling to Washington, D.C. to confront HEW Secretary Joseph Califano directly, finally forced the federal government to act.
This event stands as one of the most significant acts of disability civil disobedience in American history, proving the political power of organized disabled activists and directly leading to the long-delayed implementation of Section 504's protections. It remains a foundational story in the history of American civil rights movements broadly.
