Firefighters are expected to be on the scene of fire in College Park until at least Thursday afternoon.
Officials say a fire engine and ladder truck teams are focusing on four hot spots that continue to flare up from time to time.
The five-alarm fire broke out around 10 A.M. Monday morning at Fuse 47 apartments. That building was under construction so no one was living in them at the time.
The fire drew more than 200 firefighters and caused nearly $40 million in damages.
Officials are calling it the largest fire in the county's history.
The cause of the fire is still under investigation, but fire officials say they are leaning toward ruling it an accident.
