ALAMEDA, Calif. -- A two-alarm fire swept through two U.S. Coast Guard housing units in Alameda late Tuesday, driving a dozen people from their homes as flames raced through the structures.

According to Alameda Fire Chief Dave Kapler said the fire at 3064 and 3062 Kansas City Drive was initially reported just after 9 p.m. The blaze was controlled by about 9:30 p.m. and was contained to the two duplex-style buildings.

Kapler estimated that 12 people from the four affected apartments and one additional apartment were displaced and were being assisted by the American Red Cross, who was on the scene.

There were no injuries besides one report of smoke inhalation by a resident near the fire who was treated at the scene, the fire chief said.

The buildings sustained "fairly substantial damage," said Kapler, who added that it was too soon to access the value of the damage. The cause of the fire has yet to be determined but Kapler said it did not appear suspicious.
