Completed burglary, forcible entry, unlawful entry without force and attempted forcible entry are the four types of burglary. By definition, burglary is the illegal attempt or forceful entry of a residence.
Completed burglary involves illegally entering a residence with or without force. Illegally entering a residence through an unlocked door is an example of a forcible entry. Breaking a window and entering the residence through the window is an example of unlawful entry without force. An attempted forcible entry is a burglary where force was used in an attempt to illegally enter a residence. A burglary on a structure such as a shed or garage on the premises of a residence qualifies as household burglary.
