Child Study Institute (CSI)

Being that 428 10th Street is being demolished, we thought we’d post about it.

The Child Study Institute (CSI) in Toledo, Ohio, was a long-running Lucas County juvenile detention and evaluation facility tied to the juvenile court system. CSI on 10th Street opened in 1953. The structure was designed by the Toledo architectural firm Bellman, Gillett & Richards.

By 2000 CSI was described in the Toledo Blade as being “plagued by problems from deteriorating plumbing, aging heating systems, poorly secured detention areas, and outdated court areas.” In March 2001 operations were transferred over to a new juvenile detention center at 1801 Spielbusch Avenue. By May of 2001 equipment and fixtures at the “Old CSI Bldg” were being auctioned off. The building was used as storage over the years but eventually ended up on the Toledo Fire & Rescue Department’s Code Red list. A Code Red building is in such disrepair that it’s a danger to emergency personnel. Asbestos contamination got CSI put on the list.

In the 1920s (and into the 1930s), reform groups such as the League of Women Voters criticized the old detention-home model for children, arguing that simply jailing delinquent youth was harmful and outdated. The League advocated for a more rehabilitative juvenile court and treatment system.

1980s Annual Reports emphasized rehabilitation, counseling, family involvement, and behavioral evaluation. Community organizations continued providing support programs and recreational activities. The League of City Mothers, for example, had been involved since the 1930s by funding equipment and organizing activities for detained youth.

But, like many juvenile detention institutions of its era, the CSI was controversial at times. Court cases and later reporting documented concerns involving supervision, detention conditions, and treatment of juveniles.

By the late 20th and early 21st centuries, the name “Child Study Institute” gradually faded as Lucas County modernized its juvenile detention system. Functions formerly associated with CSI became part of the Lucas County Juvenile Justice Center and related court services.
