Firefighters contain San Luis Obispo apartment fire Friday night

A fire broke out at an apartment complex in San Luis Obispo Friday night.

Multiple firefighting units responded to a fire at the Madonna Road Apartment in the 1500 block of Madonna Road around 9:20 pm Friday.

Firefighters quickly contained the flames coming from a single upstairs unit.

A KSBY photographer at the scene saw dozens of residents outside the apartment, some who said they were evacuated from their units — some of which had lost power.

The cause of the fire is not known at this time.
