Burglary
Unlawful or forcible entry or attempted entry of a residence. This crime usually, but not always, involves theft. The illegal entry may be by force (e.g., breaking a window or slashing a screen) or may be without force (e.g., entering through an unlocked door or an open window). As long as the person entering has no legal right to be present in the structure, a burglary has occurred. Furthermore, the structure need not be the house itself for a burglary to take place; illegal entry of a garage, shed, or any other structure on the premises also constitutes household burglary. If breaking and entering occurs in a hotel or vacation residence, it is classified as a burglary for the household whose member or members were staying there at the time the entry occurred.

Attempted forcible entry - A form of burglary in which force is used in an attempt to gain entry.

Completed burglary - A form of burglary in which a person who has no legal right to be present in the structure successfully gains entry to a residence, by use of force or without force.

Forcible entry - A form of completed burglary in which force is used to gain entry to a residence. Some examples include breaking a window or slashing a screen.

Unlawful entry without force - A form of completed burglary committed by someone having no legal right to be on the premises, even though no force is used.
