Burglary is a crime related to theft. Burglary, a felony, involves trespassing, or entering a building with intent to commit any crime, not necessarily a felony or theft. Thus a conviction for burglary may qualify as a conviction under a three strikes law or habitual criminal law, even though only something of low value or nothing at all was stolen.
Laws in many jurisdictions impose much harsher penalties for burglaries committed or attempted at night, or upon an occupied residence.
Burglary laws in some jurisdictions also encompass certain types of shoplifting.
