The fire on 33rd Street was first reported around 8:15 p.m., according to a news release from Paso Robles Fire and Emergency Services.
It was located in an exterior storage space on the second floor of the building, the release said.
The fire suppression sprinkler system was working and helped mitigate the effects of the flames until firefighters could arrive on-scene.
“Due to the fire suppression system and quick actions by firefighters, there was no fire extension into the living quarters, and there was minimal damage to the structure,” the release said.
All occupants safely evacuated their homes during the blaze and were able to return after the fire was extinguished by firefighters, the release said.
The cause of the fire remains undetermined, according to the release.
Two fire engines, one battalion chief from Paso Robles Fire and Emergency Services responded to the fire, along with two San Luis Obispo County Cal Fire engines and one battalion chief and a ladder truck from the City of Atascadero Fire Department.
