Which method is used to provide notice of a hearing when the primary method of service is not obtainable?

The correct answer is secondary service, which is employed when the primary method of service is not an option. This method is essential in ensuring that all parties involved in a legal process are properly informed of upcoming hearings or actions, maintaining due process.

Secondary service typically involves alternative methods of delivering notice when the usual routes—such as personal service or certified mail—cannot be executed. This could include techniques like posting notices in public spaces or other means that ensure the information is accessible to the affected individuals. Utilizing secondary service ensures that the fundamental rights of all parties are respected, even when standard procedures are unfeasible.

Understanding the role of secondary service is critical for effective code enforcement, as it highlights the importance of communication and compliance with legal regulations.
