Laws Vary by State. There is no national law regarding a childâs minimum age to stay home alone. A few states have set forth an age, such as Oregon (10 years) and Maryland (8 years), but the majority are either completely silent on the issue or offer only recommendations. To find out the law in your state, contact your state Department of Child and Family Services.
