First-degree criminal trespass involves the offender entering or remaining in another person's dwelling unlawfully – or without their consent. It also includes entering another person's vehicle unlawfully, but only if they intended to commit a crime.
Second-degree criminal trespass, on the other hand, applies to those who unlawfully enter another person's vehicle or their property when it was enclosed to prevent intruders. This includes fenced-in areas of private property as well as lobbies and other common areas of apartment complexes, condos, or hotels.
