Two Cal Poly graduates were displaced from their home at the corner of Graves and Slack streets when a fire damaged their house Tuesday evening.
San Luis Obispo City Fire crews extinguished the fire at 101 Graves St. within 15 minutes after getting a call at 8:13 p.m. from a neighbor who reported seeing black smoke, fire Chief Garret Olson said.
The fire appeared to originate in the back of the house and caused extensive smoke damage, he said. Several fire crews attacked the fire from the inside, while another crew opened a hole in the roof to let heat and gases escape.
Olson said the cause of the fire wasn't immediately known and will be investigated, although there was no reason to believe it was suspicious.
The two men who live at the house weren't home at the time of the fire.
Diego Davila, who graduated from Cal Poly a year and a half ago, said he was watching the NBA finals basketball game at a friend's house down the street when he got a call that firefighters were at his house.
"My buddy called me and said, 'Is your house on fire? Your house is on fire,' " he said.
Davila said his roommate, who just graduated from Cal Poly, also wasn't home at the time. A third roommate had already gone home for the summer.
Olson said his department was connecting the two residents with the Red Cross to find shelter for the night.
