Officials are investigating a fire that caused an estimated $1 million in damage to Picatti Bros. in Yakima early Sunday morning.

Yakima Fire Department investigators are working with the Bureau of Alcohol, Tobacco, Firearms and Explosives to determine if video footage is available in the alley where the fire started, a news release said.

“We and the ATF are visiting businesses in the immediate area to see if there were cameras recording at the time of the fire,” Yakima Fire Chief Aaron Markham said in the release.

Firefighters were called to the blaze at 4:31 a.m. Sunday in the 100 block of South Third Avenue, and found smoke and fire coming from the Picatti Bros. building. A three-bay shop on the alley side was fully involved, with the fire extending to the main building.

Picatti Bros. services electrical equipment, pumps and wells. President Doug Picatti said Monday they are still open for business next door and customers can contact them with any questions.

He said the fire started in the loading dock, damaged a storage building and reached the roof of one of the shops. The business hasn’t fully assessed damages, he said.

The fire was extinguished by 9:30 a.m. Sunday, with damage estimates at $1 million, the fire department said. YFD was assisted by Kittitas Valley Fire and Rescue, the Yakima Training Center Fire Department and the Yakima Police Department.

Picatti’s website has a form for customers at if people have trouble getting through by phone.
