The owner of a self-service storage facility and the owner's heirs, executors, administrators, successors and assigns have a lien upon all personal property located at a self-service storage facility for rent, labor or other charges, present or future, in relation to the personal property and for expenses necessary for its preservation or expenses reasonably incurred in its sale or other disposition pursuant to this chapter. The lien provided for in this section is superior to any other lien or security interest, except liens or security interests secured by motor vehicles titled pursuant to Chapter 23 of Title 21. The lien attaches as of the date the personal property is brought to the self-service storage facility; provided that the written rental agreement states that such lien will attach.
