Oakland firefighters extinguished a house fire in a neighborhood east of Lake Merritt on Wednesday evening, a fire battalion chief said.

Firefighters were called to the home at 630 Kenwyn Road, in Oakland's Cleveland Heights neighborhood, at 6:22 p.m.

The fire engulfed three rooms on the first floor of the two-story home and was beginning to extend to the second floor when firefighters arrived, Battalion Chief Emon Usher said.

Firefighters were concerned the blaze might spread to a neighboring home and to possessions stored in the backyard, Usher said.

They also worried about a large collection of possessions stored in the basement, which could have created a hazardous situation of having fire below working firefighters. However, the fire remained upstairs.

Additional assistance was called, coming just short of a two-alarm response, Usher said. A total of 32 firefighters responded.

Firefighters eventually controlled the fire at 6:54 p.m. The home's residents were not at the scene, but at least one person seemed to be living in the house, Usher said.

No injuries were reported.

The house sustained heavy damage that Usher estimated would cost between $200,000 and $300,000 to fully repair. The cause of the fire is under investigation.
