45 CFR §410.1102

ORR may place unaccompanied children in care provider facilities as defined at § 410.1001, including but not limited to shelters, group homes, individual family homes, heightened supervision facilities, or secure facilities, including RTCs. ORR may place unaccompanied children in out-of-network (OON) placements, subject to § 410.1103, if ORR determines that a child has a specific need that cannot be met within the ORR network of facilities, if no in-network care provider facility equipped to meet the child's needs has the capacity to accept a new placement, or if transfer to a less restrictive facility is warranted and ORR is unable to place the child in a less restrictive in-network facility. Unaccompanied children shall be separated from delinquent offenders in OON placements (except those unaccompanied children who meet the requirements for a secure placement pursuant to § 410.1105). In times of influx or emergency, as further discussed in subpart I of this part, ORR may place unaccompanied children in care provider facilities that may not meet the standards of a standard program, but rather meet the standards in subpart I.
