Conceptually, 18 might mean adulthood but not in every aspect, and not necessarily biblically.
In some states many basic privileges and responsibilities of adulthood come at age 21. There may be a stronger biblical case for that age, were that definitive (I'm not sure there is a definitive age because children mature at different levels).
I think that a child living under your roof must abide by the household rules. Discipline might involve not continuing to live there.
At the time, I thought this was extreme, but one father charged his son rent when he turned 18. But one might say, summers and vacations are always free but if a child goes through college or technical school years and wants to stay home beyond those years, they must contribute to maintaining the household somehow.
My parents always seemed to have the notion that children should take their time growing up and now that I look back on it, I like that.
