Boston firefighters responded around 4:15 p.m., Sunday, to what became a three-alarm fire at 5 Everett Ave..
Two residents became trapped by the fire. Firefighters rescued both, but not before they suffered smoke inhalation, according to the Boston Fire Department.
The fire, in a six-unit, three-story building, went to three alarms before firefighters got it under control.
The department says 16 people were displaced and estimates damage at $500,000. An MBTA bus was brought in to shelter the residents until alternate housing could be arranged.
On Dec. 25, 2010, a two-alarm fire  did roughly $400,000 damage to 9 Everett Ave.
