A two-alarm fire caused serious damage to an east Petaluma home early Sunday and sent one elderly resident to the hospital with breathing problems, said Petaluma fire officials.
Petaluma firefighters were called to a home on Willow Drive at 1:58 a.m. with reports of a house on fire.
Petaluma Fire Battalion Chief Russ Rasmussen called for a second alarm, bringing additional help, due to the size of the fire and because some arriving firefighters needed to help the ailing man.
The fire apparently started on the second floor and spread into upstairs bedrooms but was stopped before it reached the rest of the home.
The home, in a subdivision near Ely Boulevard, had about $100,000 damage to the structure and contents. The cause remained under investigation.
The elderly man suffering from smoke inhalation was taken to Petaluma Valley Hospital.
The house is home to five people, including children ages 7 and 9. Two people were there when the fire started.
The Red Cross provided temporary housing for the family.
Petaluma firefighters were aided by Rancho Adobe, Cal Fire, San Antonio, Wilmar, Lakeville and Schell-Vista fire departments.
