According to HFD, firefighters responded to the building fire at around 6:04 a.m. Fire officials said that the townhome was under construction and had no windows.
The fire department said there was one firefighter, who was treated for heat exhaustion, but is expected to be OK.
Neighbors told ABC13 they saw some squatters inside the townhome, but it is unclear if they were inside at the time of the fire.
As of Sunday morning, fire officials said they are unsure whether anyone else is still inside the townhome that burned.
