A two-alarm fire caused an estimated $1.5 million in damage to an office building on South Washington Street in the City of Falls Church on Friday afternoon.

Officials say the building, located at 150 S. Washington Street behind the Ireland’s Four Provinces and directly across from the historic Falls Church, was occupied by approximately 80 people at the time the fire broke out. All escaped the building without injury. The City of F.C. Fire Marshal has ruled the fire accidental and has temporarily condemned the building. A cause has yet to be determined. The ATF-Falls Church field office assisted in the investigation and the F.C. Volunteer Fire Department assisted with overhaul. The building has been turned over to building management, who will secure the site.

More than a dozen fire vehicles and ambulances were on the scene at 150  South Washington St. around 1 p.m. Friday when fire was seen coming from the building’s second floor and heavy, black smoke was pouring out of a window facing W. Broad St. Onlookers had gathered on the upper deck of the George Mason Square parking garage and were told to step off of the upper deck by a police officer as a security precaution.

The fire was extinguished by firefighters from both Arlington and Fairfax County.

Police closed down South Washington Street between Broad Street and Annandale Road. Annandale Road was also closed between Washington and Maple Avenue. The streets are now back open for traffic.

Arlington Co. Fire says the fire was contained to 2nd floor with smoke on all five floors.

The City of F.C. released the following statement:

At approximately 1 p.m. today, Friday, March 21, a two-alarm fire broke out in an office building in the 100 block of S. Washington Street. While the fire has been extinguished, S. Washington Street is closed to traffic between Annandale Road and Broad Street.
