New Jersey Statutes Title 30. Institutions and Agencies 30 § 8-48.1

a. The governing body of any county which has adopted the provisions of the act to which this act is a supplement may, by ordinance or resolution, as appropriate, establish a program for the housing in an institution or facility operated by a nonprofit organization providing for the care, custody, subsistence, education, training, and welfare of inmates, of any person at outside labor or permitted to attend a vocational training course.

b. Upon the adoption of the ordinance or resolution any eligible inmate may be transferred to such nonprofit institution or facility by order of the sentencing judge at the time of sentencing, or by the sentencing judge or the assignment judge of the county at any time during the term of the sentence.  The court or the assignment judge ordering the transfer of an inmate shall do so on the basis of whether or not the transfer of the inmate to the facility or institution is appropriate to the needs and welfare of the inmate and other inmates, and to the security of the county jail, workhouse or penitentiary.  The sentencing judge or the assignment judge shall designate the institution or facility to which the person is to be transferred and may, at any time, require that an inmate residing in the facility or institution be sent to the county jail, workhouse or penitentiary to serve the remainder of the sentence.
