What is the penalty for burglary for a minor?

That varies depending upon the state and nature of the crime. Burglary frequently involved breaking and entry, and/or illegal entry, trespassing, and other infractions of the law. The penalty for a first offense might just be probation. It might involve some time in juvenile detention. Judges factor a number of things into their decisions on the severity of penalties. Three kids committing the same crime can receive three different sentences, depending on their backgrounds, their desire to make restitution, etc.

Many states lack strict sentencing guidelines for crimes committed by minors.
