Deputies say 19-year-old Gabriel Castillo was booked Sunday on charges of arson. They believe he set three fires in Yorba Linda and Anaheim Hills last week.
The fires came close to homes but did not cause any injuries or damage to structures.
Officials say Castillo's father is an 18-year veteran of the Orange County Fire Authority stationed in Santa Ana.
The investigation is ongoing. Anyone with additional information was to call sheriff's Investigators at (714) 647-7000.
