What is Indian Lease Land?
In 1876, Pacific Railroad laid the tracks between Los Angeles and Yuma, Arizona. The U.S. government deeded the Agua Caliente 52,000 acres throughout the Coachella Valley (6,700 acres lay within the city of Palm Springs). The government gave the railroad a checkerboard of every square mile of land for 10 miles on either side of the railroad right-of-way. The Agua Caliente tribe got the non-Pacific Railroad owned squares. The city of Palm Springs is built on a "checkerboard" consisting of alternating Indian and non-Indian land.
Some of the most popular neighborhoods in Palm Springs are on Indian land. Over 23,000 residential properties are located on Indian lease land, which give the home owner specific rights to the property for the duration of the lease. Most Indian leases are administrated by the Bureau of Indian Affairs; a homeowner doesn't deal with the Indian owners directly, but instead usually with the appointed property management company or Bureau of Indian Affairs office. Not all "lease land" properties are governed by the Bureau of Indian Affairs; some lease land parcels are owned by private leaseholders, often referred to as "Business Leases" or "Developer Leases." Review your title reports on the specific properties to determine ownership and lease status.
