A two-alarm house fire damaged a vacant home in Alamo and left two firefighters with heat-related injuries Monday afternoon, a San Ramon Valley Fire Protection District spokeswoman said.
Neighbors called 9-1-1 to report the fire at the under-construction home on Las Quebradas Lane around 1:05 p.m., fire district spokeswoman Kimberly French said.
Crews arriving on the scene saw a fire that appeared to have spread from the single-story home's side yard to its attic area, French said.
Firefighters were able to get the blaze under control in about 30 minutes, she said.
Two firefighters suffered heat-related injuries and at least one was taken to a hospital for treatment, French said. Temperatures in Alamo at the time of the fire topped 100 degrees.
The cause of the fire is under investigation.
