DC law defines a child as anyone up to age 18, but it does not specify an exact age at which children may be left home alone. Parents and guardians are expected to use their own judgment. At the same time, guidance is available to help determine when leaving a child alone may constitute neglect.

When the Child and Family Services Agency (CFSA) receives a report of a child left alone, the agency reviews each situation individually. Several factors are considered — the same factors parents and guardians should weigh when deciding whether a child is ready to self-supervise for a period of time.

• Age: Infants, young children, and others who require constant care should never be left alone. Generally, the older the child, the lower the risk.
• Maturity: Infants and young children are not ready to be unsupervised. Beyond that, parents and guardians must consider the individual child. A trustworthy 12-year-old may manage well at home for an hour while an adult runs an errand, whereas the same situation may not be appropriate for an unruly 17-year-old.
• Length of Time: There is a significant difference between leaving a child or teen alone for a couple of hours and leaving them alone all day, overnight, or for several days. In general, shorter periods of time alone carry less risk.
• Safety: Families should establish clear ground rules for children who are home alone. Children should know how to reach a parent or guardian, what to do in an emergency, and what steps to take if an adult cannot return home on time. In most cases, thoughtful planning and preparation reduce risk.

State Law vs. Local Guidance
Virginia law does not specify a minimum age at which a child may be left home alone. Lack of supervision only becomes a legal or criminal issue if it meets the state definition of child abuse or neglect under VA Code § 63.2-100. Instead, local Child Protective Services (CPS) departments publish the guidelines below as baseline benchmarks to help parents assess child readiness and to assist social workers when evaluating safety reports.
