"House guests who have been asked to leave and overstayed their welcome are technically committing a
crime—trespassing. Despite this fact, getting rid of a trespassing house guest can be challenging."
Trespassing Laws and Penalties
"Laws vary, but in most states, a person commits the
crime of trespass by entering
or remaining in a building or on land without permission from the owner or resident. Even if the owner initially gave the person permission to hang out or stay at their house, the person can still commit trespassing by not leaving when the owner asks. For example, a person who remains at a party after the owner tells them to leave is trespassing.
Many states divide trespass offenses into degrees or levels, with increasing
penalties based on the type of property or situation. For instance, trespassing on another's land might carry a
low-level misdemeanor penalty. States generally reserve the
harshest penalties for trespass of a dwelling (a place where a person lives or sleeps) or in defiance of a request to leave. A person convicted of these more serious trespassing offenses could face up to a year in
jail, fines,
probation, and potentially a no-contact or
restraining order."
Should I Call the Police for Trespassing?
"Technically, in most situations, a houseguest who remains after being asked to leave is trespassing. So how can you get an unwanted guest out of your house? First, make sure that the trespasser knows that they are no longer welcome. It can be difficult to tell friends and relatives that you want them to leave, but if you've previously given the person permission to stay at your house—and not made it explicit that you want the person to leave—they might not be violating any laws. On the other hand, if you've made it crystal clear that a guest is not welcome, but the guest continues to stay, call the police and report the person for trespassing."
Do I Have to Formally Evict an Unwanted House guest?
"There isn't a formal process (such as eviction) for getting an unwanted guest of your house. Your first step should be a straightforward one: Clearly tell the person that you need them to leave. If you want to preserve a relationship (for example, if it's a friend who won't leave your house), try to sit down with them and discuss it. If you're not comfortable doing this, give them the notice in writing—an email is fine, just make sure you keep a copy of it. No matter how you tell them their time at your place is over, be sure to give them a deadline by which they must be gone.
If they don't leave by your deadline, you could try changing the locks. However, your safety is the primary concern—don't do anything that you think could put you in danger. And don't ever use violence to try to remove an unwanted guest from your house."
