No injuries were reported in a Santa Ynez structure fire early Tuesday morning, Santa Barbara County Fire Department Capt. Daniel Bertucelli said.

Fire crews responded at 1:49 a.m. to the 3500 block of Olive Avenue and found a house’s front porch on fire, which had spread to the front room through the ceiling, he said.

The blaze was extinguished quickly and crews checked the structure to make sure the fire had not extended elsewhere in the house, Bertucelli said.

All of the home’s residents were out of the house when crews arrived and no one was injured.

The cause of the fire is under investigation.

No further details were available.
