A non-injury blaze broke out today at a three-story apartment building in Tarzana.
The blaze at 5900 N. Reseda Blvd. was reported at 1:07 p.m. and was extinguished in 19 minutes by about 50 firefighters, Los Angeles Fire Department spokesman Matt Spence said.
"It was initially reported as fire on the roof,'' Spence said, ``but it turned out to be a fire in the stairwell that started on the first floor and extended up to the top floor.''
No units were damaged, he said, adding that the cause of the fire was under investigation.
