Can a 18 year old be thrown out of house?

Yes Typically, yes. Nearly all developed areas in the United States have at least one decent rescue mission, such as Salvation Army or others run by local charitable organizations. They are generally safe and clean, and many require a breathalyzer test each time a person enters the building. Some missions require that their clients have a job and pay a minimal weekly fee to live in the mission. If you are considering the need to remove your adult child from your home, look in the phone book or contact your local crisis line for information about what shelters exist in your area. However, if you do require you child to leave the home, you may find that he is more resourceful than you thought and is able to find a place to stay with a friend. You should seriously consider removing an adult child from your home if they pose a risk to other members of the family, particularly younger siblings. This includes violence, drug or alcohol abuse, sexual abuse, criminal behavior and other problems that could either directly harm another individual or that could be an influence on younger siblings, encouraging them into the same types of behavior. For the safety of the other individuals in the family, this should be seriously considered. Often it takes a measure this drastic to cause a wayward adult child to "wake up" and make changes to their lifestyle. Many times parents actually enable their children to remain in these destructive lifestyles by continuing to rescue them from the consequences of their actions. In our world, consequences exist to deter us from destructive behavior. If we shield our children from the natural consequences of their actions, we teach them that a destructive lifestyle works.
