Senator Alvarado-Gil's legislation expands California's definition of peace officers to include deputy sheriffs from Amador and Nevada counties who work in custodial facilities. The measure adds these counties to an existing list of jurisdictions where deputy sheriffs assigned to jail operations possess statewide peace officer authority while performing their custodial duties or responding to local emergencies.

Under current law, deputy sheriffs in counties such as Butte and Calaveras who work in county jails hold peace officer status with authority extending throughout California, but only when carrying out custodial responsibilities or acting under their agency's direction during a local emergency. The bill maintains these same scope limitations while extending this classification to deputy sheriffs performing identical roles in Amador and Nevada county detention facilities.

The measure preserves all existing requirements and restrictions that apply to peace officers in custodial assignments, including limitations on their authority to situations directly related to their primary duties managing jail operations and inmate supervision. These duties encompass maintaining facility security, providing inmate care, and handling detainee transportation.
