Fire Investigation

About Us

The Fire Marshal's Office conducts Cause and Origin fire investigations throughout the unincorporated areas of the County excluding the Yakama Reservation.  Our office works with the Fire Districts to utilize resources for maximum efficiency.

Our goal is to reduce the loss of life and injury, improve health, property, and environmental quality through the reduction of fire and hazardous activity, and determining the cause of those events that do occur, and to hold those responsible accountable for their actions..


The Fire Investigation unit is staffed with personnel certified as Fire Investigators through IFSAC testing and evaluation administered by the Washington State Fire Marshal's Office of the Washington State Patrol.
