California Code, Streets and Highways Code - SHC § 5335

All notices required by this division to be given to the owner of property subject to an assessment, shall be given to the fee owner, the owner of an existing prior recorded possessory interest, and the assignor of the possessory interest created by a lease. The notices shall refer to the possessory interest against which the assessment is made.

Where the provisions of this division otherwise require any notice or documents to refer to the property subject to assessment, the notice or document shall refer instead to the possessory interest and shall contain a legal description of the possessory interest created by the lease on such property. If the legal description of the possessory interest describes an area less than the entire property ownership, the notice or document shall also contain a reference to the record of the acquisition instrument to the entire parcel from which the possessory interest was created.
