Flames were shooting through the walls of 163 Westfield Ave., when firefighters responded around 4 a.m., reports say.
One resident said that someone had been shooting off fireworks on an upstairs level of the home just before the fire broke out.
Firefighters were ordered out of the house when smoke and fire began engulfing the house, bringing the blaze to a third alarm, reports say.
The house was deemed untenable, and nearly two dozen people were displaced.
