Inland Regional Center (IRC), formally Inland Counties Regional Center, Inc.,[3] is a government-funded not-for-profit public benefit corporation that provides services and programs to more than 33,000 people with developmental disabilities and their families[4] in California's San Bernardino and Riverside Counties.

Lake Elsinore state Assemblyman Kevin Jeffries unsuccessfully introduced legislation to split the agency and increase transparency.

[10] However, as of November 2016[update], the station location is no longer planned to be adjacent to the center due to heightened security after the 2015 shooting.

[11][12] On December 2, 2015, husband and wife Syed Rizwan Farook and Tashfeen Malik perpetrated a terrorist attack at the center, which consisted of a mass shooting and an attempted bombing and resulted in 14 dead and 22 injured.

[13][14][15][16][17] The shooters targeted an event for employees of the San Bernardino County Department of Public Health, held in an auditorium with about 80 people.
