Cobb County Government

Fire Investigations

Cobb County ’s first fire investigation unit was formed in conjunction with building inspections under the newly formed Fire Marshal’s Office in 1968. Today, the fire investigation unit consists of (5) full time investigators. The unit investigates on average between 200-250 fires annually.

All investigators are certified fire investigators, firefighters, and peace officers. Investigators are on call 24-hours a day 365 days a year to respond outside of their normal office hours. Cobb Fire Investigators are responsible for investigating all suspicious and non-suspicious fires where a cause cannot readily be determined by on scene personnel. This responsibility also includes fires resulting in injury and/or death.

We also work closely with the Fire Marshal’s Office, Public Fire & Life Safety Education Division and the Juvenile Fire Setter’s Program to identify and eliminate potential life safety hazards. We are active members of the Metro Arson Task Force (ATF), Metro Fire Investigators Association and the Georgia Fire Investigators Association.



The crime of arson is one of the most costly human-made disasters. Arson indirectly contributes to increased insurance premiums, higher medical costs, lost jobs, lost income, and the increased costs of fire services. We need your help to combat this serious crime. If you have any information regarding any fire related crimes, please contact the Cobb County Fire Investigations Unit.
