Residential, Single Family Home Napa, CA – Garage fire at home suppressed by automatic sprinkler system July 19, 2018 viking210 Napa Fire responded at 3:30 p.m. Monday to a reported structure fire in a home at the corner of Maximilian Court and Jefferson Street in north Napa only that the fire, located in a detached garage, had been extinguished by an automatic sprinkler system before they arrived, Capt. Steve Becker said. Damage was confined to a cluster of items in a corner of the garage, Becker said. This is another example of an automatic sprinkler, mandatory in new construction in Napa since the 1980s, reducing fire loss, he said.
