Oregon Revised Statutes Mortgages and Liens § 87.687

(1) The owner of a self-service storage facility has a lien upon all personal property, whether or not owned by the occupant, that is located in a specified storage space rented by an occupant at the facility to secure payment for rent, reasonable or agreed charges for labor, materials or other services provided by the owner at the request of the occupant, expenses necessarily incurred in preserving the personal property and expenses reasonably incurred in the sale or other disposition of the personal property under ORS 87.689. The owner may retain the personal property until the rent and other charges and expenses are paid.

(2) The lien created by this section attaches to personal property of an occupant at the time at which the personal property is stored at the self-service storage facility.

(3) Except for a lien or security interest that is perfected prior to the attachment of the lien created by this section, the lien created by this section has priority over any other lien or security interest or encumbrance on the personal property subject to the lien.
