PIEDMONT -- A fire that started at a sprawling Piedmont house jumped to two other homes and a small patch of vegetation Tuesday afternoon before all the fires were contained, fire officials said.

An Oakland firefighter who was burned by the engine of a support vehicle was taken to the burn center at San Francisco's Saint Francis Memorial Hospital, treated and released. No one else was injured.

The fire damaged two stories of a tri-level house at 150 Maxwelton Road. While Oakland fire crews helped Piedmont firefighters battle that fire, flames spread to the roof of 140 Maxwelton Road and one side of 180 Maxwelton Road.

A small vegetation fire also started but was quickly controlled by a resident. The additional fires brought the fire from one to two alarms for a brief time and utilized 40 Oakland firefighters and eight members of the Piedmont Fire Department.

The family at 150 Maxwelton was displaced from their home, a fire official said.

The original fire broke out about 2:32 p.m. and was under control in about an hour. All the fires were out by about 4 p.m. but crews were on scene until after 5 p.m. checking on hot spots and doing clean up. Crews also continued to monitor the area Tuesday night.

The cause of the fire was not immediately known and a damage estimate was not available.
