SAN RAFAEL – Fire crews have contained a three-alarm fire Monday afternoon at a large apartment complex on Canal Street in San Rafael.

No one was injured in the blaze, which was reported about 2:35 p.m. at a four-story structure in the 400 block of Canal Street, San Rafael Fire Deputy Fire Chief Robert Sinnott said.

The fire was sparked accidentally in the bathroom wall of a second-floor apartment that was under construction. The blaze traveled to upper floors and seven units were damaged before the fire was contained at 3:40 p.m., Sinnott said.

The complex, which has 99 apartments, was partly evacuated.
