WASHINGTON (WUSA9) -- D.C. Fire and Rescue officials responded to the scene where two buildings collapsed in the 400 block of K Street, Northwest.
An adjacent strip club was evacuated due to the collapse. One person was treated for minor injuries, although, by the looks of what's left of the buildings, it could have been worse.
The two inner-buildings of four connected buildings collapsed from roof to basement. The one of the inner buildings initially collapsed from the third floor to the basement, and shortly after, the second inner building collapsed into the basement.
Firefighters had just finished searching the wreckage when the second collapse happened.
"We did have a close call. Upon our members exiting to determine if there were anyone in the structures I would say about five to ten minutes later the second collapse occurred. Fortunately, no one was in the building," said Tim Wilson, spokesperson for DCFD.
The two outer buildings are standing but authorities fear they may become unstable due to the collapse.
"There's still a lot of investigation to determine whether or not these buildings are safe or not," said Wilson.
The buildings are commercial structures that have historic designations by the city.
Officials said the fallen buildings were being renovated and that might have had something to do with the collapse but that's still being investigated.
Experts expect to be back out at the scene Saturday to survey the buildings and see what can be salvaged and what needs to be torn down.
