Amends GS 153A-218 to add that a person under age 18 must not be housed in the same local confinement facility as those 18 and older unless, in the judgment of the custodian based on the facts other than the underlying offense with which the juvenile is charged, the juvenile has demonstrated that the juvenile is a threat to the security or safety of other juveniles detained or the staff of the home or the facility. Directs a judge to determine whether that juvenile can be transferred to a jail or other facility for the detention of adults. Requires a complete sight and sound barrier to be maintained between those under the age of 18 and those 18 and older if a person under 18 must be housed in a facility also housing people 18 and older. Updates a statutory reference. 

Applies to requests for proposals for letting of public contracts issued on or after the date the act becomes law.
