You can remove a family member's belongings after an eviction, just like any other tenant's. It depends on the state's rules. If you must hold them in a secure location for a set period of time, you must comply. However, if any of the property in the room was yours prior to the relative living in the room, you may reclaim it. You are not required to keep them in the same room or in the house. If state laws require keeping them in a "safe place," you can move them to a garage or storage facility. Your family member will be subject to the same laws about repaying storage fees under state law as any other tenant.
