The service of any order provided for by the preceding section may be made upon the occupant of the premises to whom it is directed, either by delivering a copy of same to the occupant personally or by delivering the same to and leaving it with any person in charge of the premises, or in case no such person is found upon the premises, by affixing a copy thereof in a conspicuous place on the door to the entrance of the premises. Whenever it may be necessary to serve such an order upon the owner of the premises, the order may be served either by delivering to and leaving with such person a copy of the order, or, if the owner is absent from the jurisdiction of the officer making the order, by mailing the copy to the owner's last known post office address.
