Marietta maintains a minimum of one full-time certified investigator to be on-call at all times. This is handled by certain qualified officers working in the Fire Marshal's Office. In the event additional investigators are needed to assist, all of the officers assigned to the Fire Marshal's Office are trained in the investigation of fires to determine origin and cause.

The Fire Investigation section of the Fire Marshal's Office also assists in conducting internal affairs investigations, enforcing fire codes and local ordinances, issuing citations and works directly with the Marietta Police Department.
