A firefighter was taken to a hospital to be treated for smoke inhalation after battling a two-alarm fire at an apartment building in the Oceanview neighborhood Thursday morning, Assistant Fire Chief Tom Siragusa said.

The Fire Department received reports of a fire on the second floor of a three-story building at 119 Broad St., between Capitol and Plymouth avenues, at 5:31 a.m.

The building was evacuated of 25 residents before the blaze was controlled at 6:14 a.m., fire officials said.

No other injuries were reported, and the cause of the fire remains under investigation.

By 2:30 p.m., construction crews had already started clearing debris and assessing the damage.

The building sits adjacent to a Victorian-style firehouse built in 1896. In 1973, the firehouse was deactivated.

The American Red Cross responded to the scene to assist displaced residents.

The fire disrupted service on Muni’s M-Ocean View line.
