What is one of the alternative methods of service at the option of local authorities?

One of the alternative methods of service that local authorities can utilize is the publication in a newspaper. This method is particularly useful when the whereabouts of the property owner are unknown, making it difficult to deliver notices through personal contact or direct mailing. Publicizing the notice in a newspaper serves to inform the community and ensures that the responsible parties are reached, as it is a widely recognized method of disseminating important information. Additionally, publication fulfills legal requirements in many jurisdictions, demonstrating due diligence in the service process.

Methods like personal delivery or handing notices to officials such as the local mayor may not effectively reach the intended recipients, especially when compliance or legal actions must be formally documented. Emailing the notice could present issues of verifying receipt, as not all individuals maintain an active email address or may not check their inbox regularly, which could complicate enforcing compliance with local laws. Therefore, publication in a newspaper stands out as a legally effective backup method for notifying property owners in a transparent and verifiable manner.
