ALAMEDA -- A residential fire on Park Street Friday morning caused about $35,000 in damage before it was contained, firefighters said.

No one was hurt as a result of the blaze, which was reported at 8:43 a.m. in a second story unit above a business in the 1800 block of the street, Alameda Firefighter Jim Colburn said.

"Firefighters pulled pre-connected hose lines from the first arriving engine, forced entry and attacked the fire while others searched for occupants and ventilated the building," Colburn said in a release.

A total of 26 firefighters responded and no one was hurt.

Along with the Alameda Fire Department, the Alameda police and Alameda Municipal Power were at the scene, while the Oakland Fire Department covered Alameda fire stations as part of a mutual aid agreement between the cities of Alameda and Oakland.

The fire caused about $25,000 in damage to the structure of the building and about $10,000 in damage to the unit's contents, Colburn said.

The cause of the fire remains under investigation.
