Nacht & Lewis has designed multiple phases of the Lake County Adult Detention Facility starting with the original jail facility, which was completed in 1990. The firm assisted Lake County with their successful SB1022 application in 2013 and is currently designing the expanded facility which includes a new public entry with visitation and a 40-bed female dormitory, a new 39-bed medical and mental health housing and program building and a new administration building. The plan also includes a new security perimeter, new visitors’ parking and re-planning of the existing building to improve security, circulation and access to inmate programs / services. With the new construction the facility will have a board rated capacity of 279 Beds inmates in a mix of maximum and medium security celled housing and minimum security dormitory housing. In addition, the facility will gain 39 special use beds for medical and mental health treatment.

Prior Work in Lake County

Phase I, completed in 1990, included two 56-Bed dormitories, one each for sentenced males and females, 21 single cells for pre-sentenced females including intake/release, a central kitchen and laundry facilities, and staff and inmate service space.

In Phase II, completed in 1999, Nacht & Lewis designed a housing unit and an intake/release facility addition. The housing unit contains three maximum-security pods of two-tier configuration with a total of 35 cells and two medium security dormitories with 24-bed capacity each. It has two integral recreation yards, visiting space, medical and program rooms. The housing unit is controlled by the control room at the upper level with a direct view into all housing pods, recreation yards and visiting. The intake/release provides a pre-booking interview area, holding cells, booking lounge, three detox rooms and dressing in/out cells adjacent to property storage room and court transfer holding. The central booking counter provides for overview to all inmate spaces.

Phase III, completed in 2003, added bed capacity to the phase I facility. The additional cells were built in shelled space that was planned into the original facility for future expansion.
