Residential, Single Family Home Brentwood, CA – Residential sprinkler system contains garage fire at house November 18, 2015 viking210 Fire crews were called to the 1300 block of Castello Ranch Road around 1:45 p.m. Monday and found a fence on fire between two houses, Battalion Chief Jeff Burris of the East Contra Costa County Fire Protection District said in a statement. The fire also extended into garage of one of the houses. Crews extinguished the fire on the fence, while the fire in the garage activated a residential sprinkler system that limited the damage to the exterior of the left side of the garage wall, Burris said. Investigators determined that ashes from a barbecue that were thrown into a plastic garbage bag stored next to the fence likely started the fire. The fence between the homes was destroyed. Investigators said the financial damages to the fence and garage were approximately $50,000. Nobody was injured.
