(A) Notices or orders issued by the Code Enforcement Coordinator or officer under this article shall be served upon persons either personally or by registered or certified mail and, in conjunction therewith, may be served by regular mail. When the manner or service is by regular mail in conjunction with registered or certified mail, and the registered or certified mail is unclaimed or refused, but the regular mail is not returned by the post office within ten days after mailing, service shall be deemed sufficient. The person mailing the notice or order by regular mail shall certify that fact and the date thereof, and the certificate shall be conclusive in the absence of fraud.
(B) If the identities of any owner or the whereabouts of persons are unknown and cannot be ascertained by the Code Enforcement Coordinator or officer in the exercise of reasonable diligence, and the Code Enforcement Coordinator or officer makes an affidavit to that effect, then the serving of the notice or order upon the unknown owners or other persons may be made by publication in a newspaper having general circulation in the city at least once no later than the time at which personal service would be required under the provisions of this article. When service is made by publication, a notice of the pending proceedings shall be posted in a conspicuous place on the premises thereby affected.
