The fire was extinguished at around 8:39 a.m. and additional fireworks on the balcony of an unoccupied unit on the second floor were secured minutes later, officials said.
Fire officials said the fire appeared to have started on the second floor and eventually spread to the third floor.
“Fireworks were involved, however, the cause of the fire remains under investigation,” Heflin said.
No residents were hurt in the blaze. At least two people were displaced by the damage caused by the fire.
