A fire broke out in one unit of a two-story condominium complex in Pacific Beach Thursday morning, causing one person to be treated at the scene for smoke inhalation and displacing four residents and a pet, authorities said.

The blaze was reported shortly before 4:30 a.m. in the 1500 block of Diamond Street, west of Ingraham Street, according to the San Diego Fire-Rescue Department.

Firefighters arrived at the scene and two off-duty firefighters who lived near the complex pointed them to flames coming from a room on the first floor of the building, which had parts for motorcycles and cars inside it, SDFRD spokesman Jose Ysea said.

Crews had the flames knocked down within 12 minutes, Ysea said.

The fire was contained to the one room, but the unit and one unit upstairs sustained smoke damage, he said. One person was treated at the scene for smoke inhalation.

The American Red Cross was called in to help the displaced residents — four adults and one pet — arrange for temporary lodging.

The cause of the fire was under investigation.
