Service of the notice shall be made upon the persons entitled thereto either personally or by mailing a copy of such notice by certified mail, postage prepaid, return receipt requested, to each such person at his or her address as it appears on the last equalized assessment roll of the county or as known to the manager. If for any such person no address so appears, or no such address is known to the manager, a copy of the notice and order shall be so mailed, addressed to such person, at the address of the premises on which the utility disconnection will take place. When the manager is unable to ascertain the name of the occupant of the premises he or she shall provide notice by posting the premises in a conspicuous place or by mailing a copy of such notice addressed to the occupants at the premises.
No failure of any person entitled to notice pursuant to this section to receive such notice shall affect the validity of any action taken by the manager. (Prior code § 9.01.031)
