What is the legal term for the unlawful entry into a building with the intent to commit a crime?

The legal term for the unlawful entry into a building with the intent to commit a crime is burglary. This definition encapsulates the essential elements of burglary, which include not only the act of entering a building or structure without permission but also the intent to commit a crime upon entry, such as theft or another felony.

Burglary is typically classified as a more serious offense because of its implications regarding personal safety and property rights. The act of planning to enter with intent demonstrates premeditation, which is a key factor in differentiating burglary from other offenses such as robbery or larceny.

Robbery, for instance, involves taking property from a person through force or threat, while larceny refers specifically to the unlawful taking of someone else's property without intent to return it. Trespassing generally covers unauthorized entry onto land or property but does not necessitate any intent to commit a crime. Thus, burglary distinctly aligns with the criteria presented in the question, making it the correct legal term.
