The Sylmar Juvenile Hall visiting hours are on Saturdays and Sundays from 1pm to 4pm. Only parents, grandparents, and legal guardians can visit unless the court or Supervising Probation Officer makes an exception for other relatives. You are also entitled to a 20-minute after court visitation on days your child has court. These after court visits occur between 5pm and 7pm on the day of their court appearance. Sylmar Juvenile Hall requires visitors to dress appropriately, and you may bring no belongings other than a couple of keys and your ID.
