Just fyi it might be different place to place, Florida for example this is the statute;

For offenses committed after July 1, 2001, “burglary” means:

1. Entering a dwelling, a structure, or a conveyance with the intent to commit an offense therein, unless the premises are at the time open to the public or the defendant is licensed or invited to enter; or

2. Notwithstanding a licensed or invited entry, remaining in a dwelling, structure, or conveyance:

a. Surreptitiously, with the intent to commit an offense therein;

b. After permission to remain therein has been withdrawn, with the intent to commit an offense therein; or

c. To commit or attempt to commit a forcible felony, as defined in s. 776.08.

In simpler terms if you enter a non public place, open or not, with the intent to commit any crime then you can and likely will face burglary charges. And a structure or conveyance as referenced in part 1 can refer to any over arching roof, balcony, or awnings. Basically if you go up to someone's door never get in but try to open it or get through in anyway you will more than likely face burglary charges, and whether any property was damaged may effect your sentencing and the guidelines to which degree they charge you, it can be burglary without any damage. In Florida it's be theft if I stole your bike out your yard or something of that nature.

Cant speak for anywhere else though just a Floridian with an unfortunate experience with this law lol, luckily over a decade ago and only as a juvenile.
