N.M. Admin. Code § 8.14.14.2
This regulation applies to all New Mexico juvenile detention centers operating under the certification of the children, youth and families department and managed by county and local jurisdictions. Juvenile detention centers detain delinquent offenders, youthful offenders, and serious youthful offenders. Juvenile detention centers detain juveniles pending court hearings but do not provide for long-term care and rehabilitation of adjudicated juveniles. Juvenile detention centers shall not detain children younger than the age limit identified in the Children's Code, status offenders, persons charged or previously adjudicated as delinquents or youthful offenders who are 18 years of age and older who have previously been detained with an adult population, or persons who are 18 years of age and older who are participating in a juvenile specialty court program serving custodial sanctions.
