Former Orin Allen Youth Rehabilitation Center (Byron Boys Ranch) was the county youth rehabilitation facility at 4491 Bixler Road, Byron, CA 94514. Current Contra Costa County archived board coverage states that supervisors voted on November 1, 2022 to close the Orin Allen Youth Rehabilitation Facility within 60 to 90 days and replace it with a home-based program model.

This page preserves the former Byron ranch in the Light in Prison dataset as a historical youth institution rather than presenting it as an active county facility.
