By Federal standards, a collocated facility is defined as a juvenile facility that is in the same building as an adult jail or lockup or is part of a related complex of buildings located on the same grounds as an adult jail or lockup. A complex of buildings is considered related when it shares physical features such as walls and fences or services beyond mechanical services (heating, air conditioning, water, sewer) or beyond specialized services such as medical care, food service, laundry, maintenance, and engineering. All of the staff at the detention canter are trained and certified to work with children, and the facility has been approved as a collocated facility by the Office of Juvenile Justice and Delinquency Prevention.
