Senate Bill 1292 proposes significant changes to the boundaries of Maricopa County in Arizona, effective January 1, 2025. The bill would move portions of Maricopa County into the boundaries of neighboring counties: Gila, La Paz, Pinal, Yavapai, and Yuma. The bill also requires the Legislative Council staff to prepare legislation to conform the Arizona Revised Statutes to the new county boundaries for consideration in the Fifty-Seventh Legislature, First Regular Session.

The bill originally included the formation of three new counties—Hohokam, Mogollon, and O'odham—but amendments adopted by the committee eliminated these provisions. Instead, the bill now focuses on modifying the existing boundaries of Maricopa County and making conforming changes. The bill also outlines a transition period for Maricopa County operations and the election of new boards of supervisors for the affected counties. The act is set to become effective at the end of 2024.
