Fla. Stat. § 83.805
The owner of a self-service storage facility or self-contained storage unit and the owner's heirs, executors, administrators, successors, and assigns have a lien upon all personal property, whether or not owned by the tenant, located at a self-service storage facility or in a self-contained storage unit for rent, labor charges, 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 ss. 83.801 - 83.809. The lien provided for in this section attaches as of the date that the personal property is brought to the self-service storage facility or as of the date the tenant takes possession of the self-contained storage unit, and the priority of this lien shall be the same as provided in s. 83.08; however, in the event of default, the owner must give notice to persons who hold perfected security interests under the Uniform Commercial Code in which the tenant is named as the debtor.
