Many counties have received major benefits from their jail industry programs, including inmate income to pay room, board, and restitution; reduced inmate idleness, tension, and mischief; and positive publicity for the facility. National experience demonstrates that inmate work and industry activities can be implemented inside the jail building, in program and activity areas, in support-service areas, adjacent to the jail and within the secure perimeter, and near the jail and outside the secure perimeter. National experience suggests the need for flexibility in the design and use of space. The American Institute of Architects Committee on Architecture for Justice and the Jail Industry Association jointly published the Jail Industries Space Planning Guide in 1997. The BJA Jail Work and Industry Center serves as a national clearinghouse for information and assistance. BJA, the National Institute of Justice, and the National Institute of Corrections have actively provided assistance to counties that want to develop or expand their inmate work and industry programs. The development process is perhaps the crucial determinant of initial and ongoing success for a program. The development process should rest on 18 basic principles and concepts. In addition, many new ways exist to develop county-to-county, county-State, and jail-private sector partnerships to expand inmate work and industry activities. Photographs
