The lien provided for in this chapter is junior to any other liens or security interests which are perfected and recorded or liens by any lienholder with an interest in the property of whom the owner has knowledge either through the disclosure provision of the rental agreement or through other written notice. The lien attaches as of the date the occupant is considered in default.
