Most judges frown on children being left home alone under the age of 14. This is not a rule; it is simply a rule of thumb. There is no specifically set age in the Code, and this decision is really a matter of maturity and ability to handle being alone. Under 14, however, is often a "red flag" to judges, so I advise my clients to avoid leaving their kids alone until that age.
There is likely no particular age stipulated under California law since many factors such as the child's age, maturity, intelligence, etc. may figure into this determination.
