Overview of New York Burglary Laws
A person is guilty of committing burglary in the third degree - the least of the burglary offenses - when he or she “knowingly enters or remains unlawfully” in a building with the intent to commit a crime therein. “Entry” of a building occurs when a person intrudes within a building, no matter how slightly, with any part of his or her body.
Examples of Entry
Examples of entry include crossing the threshold of a building or reaching an arm through a window. Section 140 of the New York Penal Code states that a person enters or remains on a premises “unlawfully” when he or she “is not licensed or privileged to do so”; the entry need not be forcible in nature.
All burglaries in New York State are felonies. The unlawful surveillance charge is what elevates the crime to burglary, because he had intent to take video of his wife caught in the act.
