A blaze destroyed a Hidden Valley Lake home near Middletown Wednesday afternoon, Cal Fire said.

An investigation into the cause remained underway Thursday. It appeared the fire started in a rear room of the Mountain Meadow South home, Cal Fire Battalion Chief Mike Wink said.

Firefighters were called just before 2 p.m. Wednesday and found flames throughout the single-story, 2,500‑square‑foot home. The fire also threatened two houses on either side, Wink said.

Firefighters kept the flames from spreading to the nearby residences but the main house couldn’t be saved, Wink said. He estimated the loss at $350,000.

Residents left the house just prior to the fire starting and returned to find about two dozen firefighters and nine engines and water tenders at the property.

Cal Fire, South Lake County Fire, Lake County Fire and Northshore Fire responded. The fire was under control in about 90 minutes, but firefighters stayed at the property for about four hours to mop up, Wink said.
