All citations, orders and notices required by this chapter may be served either by personal delivery or certified mail, postage prepaid, return receipt requested, addressed to a location reasonably calculated to give notice to the alleged violator, and shall be deemed effective on the date of personal delivery or when delivery is attempted. If the certified mail receipt is returned unsigned, then service may instead be effected by first class mail, postage prepaid, provided that the notice sent by regular mail is not returned by the postal service as undeliverable, and shall be deemed effective on the date three days following deposit in the mail. Service may be effected alternately or additionally by posting a copy of the order at a conspicuous location on any real property that is the subject of the order.
