A fire broke out on an unoccupied floor of D.C. General, the city’s main family homeless shelter, on Saturday night—displacing 31 families. Officials have declared it arson, and are continuing to investigate. No injuries were reported, according to D.C. Fire and EMS.

Of the more than 250 families housed at D.C. General, two dozen were moved to hotels and another seven are staying with friends. After contractors finish a deep clean, they should be able to return on Wednesday afternoon, according to Chris Geldart, the Director of the District of Columbia’s Homeland Security and Emergency Management Agency.

While the fire was contained to a small area of the sixth floor, water and smoke seeped into occupied rooms on the fifth floor. The air has been tested and no contaminants were found, Geldart says, and DHS brought in an additional contractor to launder belongings that got wet.

While the sixth floor was always off limits, there are now added additional barricades and security guards. “We’ve made sure that we stationed people up on the sixth floor and they are more prevalent through the building, Geldart says.

After much back and forth, the city finally came to an agreement in May to close the dilapidated D.C. General and replace it with smaller facilities distributed throughout the city. Although Mayor Muriel Bowser initially said they all must be completed before closing D.C. General, the administration will weigh the possibility of closing the facility in stages once the plans for the new buildings are further along.

“The mayor and the city want D.C. General closed, we all want that,” Geldart says. In the meantime, “the building is definitely getting back to where it was prior to the fire. We’re trying to do all we can for the residents to make sure they have a safe, comfortable environment.”
