But as another adult,
you have the right to evict him, but NOT the right to violate his
his human rights, OR "quiet enjoyment of the premises" as long as
you permit him to live there, and like any other adult it would
require 30 days written notice and maybe a formal notice to quit
the premises taken out at the courthouse to remove him legally.

Not if he isn't charging him rent (or other contractural basis for his
tenancy).
Absent that, he can be removed at any time as an "unwanted person."
