About the Independent Office of Audits and Investigations

SB 1 requires the Governor to appoint an Inspector General to lead the Independent Office of Audits and Investigations (IOAI), and upon confirmation of the California State Senate, the Inspector General serves a six-year term. The Inspector General is vested with the authority to maintain a full-scope, independent, and objective audit and investigation program. The Inspector General has a duty to review policies, practices, and procedures and conduct audits and investigations of activities involving state transportation funds administered by Caltrans. IOAI audit staff is organized into three offices—Finance and Operations, Project Delivery, and Planning and Modal. IOAI also includes an Investigations office and a Deputy Inspector General for Diversity and Small Business Development.
