   (b)   Such notice shall be deemed to be properly served if a copy thereof is: 
      (1)   Delivered to the owner personally; or
      (2)   Sent by certified or registered mail addressed to the owner at the last known address with return receipt requested. 
   If the certified or registered letter is returned showing that the letter was not delivered, a copy thereof shall be posted in a conspicuous place in or about the structure affected by such notice.  Service of such notice in the foregoing manner upon the owner's agent or upon the person responsible for the structure shall constitute service of notice upon the owner.
