How Old Does a Child Need to Be to Stay Home Alone in New Jersey?

The New Jersey Department of Human Services recommends that no child under 18 be left home alone if the child cannot demonstrate responsibility, good judgment and knowledge about safety and does not have a good relationship with the parents and siblings. The National SAFE KIDS Campaign recommends that only children 12 and over be left home alone. It is also recommended that families establish good rules and provide emergency contacts.
