Firefighters extinguished a blaze at a sober living home in the 900 block of Long Beach Boulevard at about 9 a.m. Tuesday, authorities said.

No injuries were reported. It was not clear how many people were living in the home, but all occupants got out safely, spokesman Brian Fisk said.

The fire took only a few minutes to knock down.

Investigators were on the scene to determine the cause, Fisk said.
