AZ HB2176

Requires Arizona's land commissioner to annually request the federal government relinquish all constitutionally nonenumerated federal land in Arizona through sale or to the state land trust by December 31, 2025.

Directs the attorney general to initiate legal proceedings against the United States beginning January 1, 2026 to force relinquishment of remaining nonenumerated federal land to the state land trust.

Excludes from relinquishment requirements: federal reclamation project lands, property with permanent improvements or legal encumbrances, electrical power project lands, national parks, Indian reservations, military installations, and federal structures.

Defines "constitutionally nonenumerated federal land" to include Bureau of Land Management holdings, national forests, wilderness areas, wildlife refuges, national monuments, and national historic sites, but excludes lands serving enumerated constitutional purposes.

Contains legislative findings asserting that 42.1 percent of Arizona land held by the federal government exceeds constitutional authority and violates the Equal Footing Doctrine when compared to eastern states.
