The acts of breaking and entering a building were historically part of the definition of the crime of burglary. But most states have since broadened the definition of burglary to include any entry into a building without the permission of the owner and with the intent to commit a theft, assault, or other crime inside the building. But a few states still have a distinct criminal offense of breaking and entering a building.

And some states have a similar criminal offense of forcible and unlawful entry that make it a crime to force entry into an automobile, safe, ATM, parking meter, or vending machine.

Breaking and entering laws (and related property crime laws) are usually located in a state’s penal or criminal code (statutes).

In Oregon, the crime of burglary is defined under ORS 164.215 and 164.225. The statutes have indeed broadened the traditional definition of burglary. In Oregon, a person commits burglary by entering or remaining unlawfully in a building with the intent to commit a crime therein. The entry does not need to involve force or breaking; simply entering without permission with criminal intent suffices. The crime is classified as Burglary in the First Degree when it occurs in a dwelling, or if the person possesses a burglary tool or weapon, or causes injury to any person during the crime. Burglary in the Second Degree applies to unlawful entry into any other type of building or structure. Additionally, Oregon law addresses related property crimes such as criminal trespass, which can involve entering or remaining on property without authorization. While Oregon does not have a distinct offense titled 'breaking and entering,' the elements of such an offense are largely encapsulated within the burglary and criminal trespass statutes.
