If you bring in a roommate as a subtenant, your tenant is not responsible to pay your late fees. The only late fees a subtenant will owe are those described in the lease between you and your subtenant. You cannot unilaterally demand and impose storage fees.

You have filed for a restraining order that keeps your ex-roommate from collecting her bed, so obviously it's going to be difficult for her to collect her bed. How do you propose that she is going to be able to collect her bed without violating the restraining order that you obtained?
