House Bill 1375 establishes the Florida Museum of History, empowering the Department of State to collaborate with county commissions in Orange, St. Johns, and Miami-Dade Counties, along with local entities, to design, construct, operate, and manage the museums. Each museum will be owned by the designated local entity, and an Advisory Committee will be formed to guide the planning and construction, comprising members with expertise in Florida history, Black history, curation, architecture, and museum design. The bill also requires each county commission to create a Florida Museum of History Board to oversee the museums, ensuring community engagement and educational outreach are prioritized.

The legislation mandates a minimum of 10,000 square feet of exhibition space for the museums, with at least 33 percent dedicated to Florida's history, covering various topics such as tourism, military presence, agriculture, and space exploration. It encourages the inclusion of exhibition halls that highlight diverse aspects of Florida's history, including African American, Hispanic, and Jewish Holocaust narratives, as well as significant historical events and figures. The bill emphasizes community involvement and financial sustainability, with the Legislature allocating at least $1 million to each county for feasibility studies and requiring local entities to match at least 50% of the funding. The act is set to take effect on July 1, 2026.
