- Install the free HeadingsMap tool: Get HeadingsMap.
- Once installed, open the HeadingsMap panel on this page.
- Review the heading structure of the content sections and observe how a logical hierarchy supports navigation and understanding — and how poor heading structure creates confusion.
For this activity, pretend the content below is on its own webpage. Use it to practice checking heading structure as if it were a full page.
The 504 Sit-In and Its Legacy
What is Section 504?
Passed in 1973 as part of the Rehabilitation Act, Section 504 was the first federal civil rights protection for disabled people, prohibiting discrimination by any program receiving federal funds.
Why 504 Was Needed
People with disabilities faced daily discrimination, such as being denied education, employment, or basic access to public spaces.
Government Delays
Even though Section 504 became law in 1973, the federal government failed to issue regulations to enforce it. This meant that, in practice, disabled people were still denied access to education, jobs, and public programs.
The 504 Sit-In
To demand enforcement of Section 504, more than 100 disabled activists, including Judy Heumann, Kitty Cone, and Brad Lomax, organized and occupied the San Francisco federal building for 26 days in April 1977, becoming the longest sit-in at a federal building in U.S. history.
Solidarity During the Sit-In
The success of the sit-in depended on broad community support, showing the power of cross-movement and cross-disability solidarity. Activists, allies, and organizations worked together to sustain those inside.
Examples of Cross-Disability and Cross-Movement Solidarity
When the government cut off the building’s phone lines, Deaf activists used sign language through windows to communicate with supporters outside. The Black Panther Party delivered hot meals to sustain the occupiers throughout the sit-in.
Lasting Impact of 504
The sit-in led to the signing of the 504 regulations, which finally enforced the rights of disabled people and laid the groundwork for future legislation like the Americans with Disabilities Act (ADA).
504’s Relevance for Older Adults
Today, Section 504 continues to protect older adults who may acquire disabilities as they age, ensuring their right to access federally funded programs, healthcare, housing, and other essential services without discrimination.
