A fire broke out at a San Marino house under renovation early Thursday morning, causing an estimated $2 million in damage, the fire chief said.

No one was injured in the fire at 1212 Roanoke Road, which was reported to the San Marino Fire Department at 12:07 a.m., Fire Chief Mario Rueda said.

The fire was not suspicious, he added.

“It appears to be related to the construction,” he said without elaborating.

The fire caused extensive damage to the vacant house and got into concealed spaces in the walls and attic, the fire chief said.

It took 33 firefighters from the San Marino, Pasadena, Alhambra and San Gabriel fire departments about 50 minutes to knock down the blaze, Rueda said.

Firefighters stayed on the scene for a couple of hours more to ensure the fire was completely out.

According to Redfin, the house encompassed 2,868 square feet.

Public records show it had three bedrooms and two baths, and was last sold Feb. 11, 2021, for $2.45 million.
