(1) All persons identified in the order must be served either personally or by mail.

(2) If the address of a person cannot reasonably be ascertained, then a copy of the order must be mailed by certified mail, return receipt requested, to such person at the address of the location of the violation and a copy must be posted in a conspicuous location on the premises. The failure of any such person to receive such notice does not affect the validity of any proceedings taken under this chapter. Service by certified mail is effective on the date of mailing.

(3) Posting. A copy of the order must also be posted at a conspicuous place on the relevant property that is the subject of a violation, unless posting the notice is not physically possible or poses a risk of harm to the city official. (Ord. 1517 § 1 (Exh. A), 2023).
