Firefighters were dispatched just before 2:30 a.m. to the 5000 block of Tacoma Street. They arrived to find heavy fire on the first floor of a three story attached home.
The home is reportedly vacant, but attached to an occupied home.
Firefighters report from the scene that there appears to have been a squatter in the home.
One person was transported to Albert Einstein Medical Center for treatment of unspecified injuries.
There is no word yet on what may have sparked the blaze.
