Wisconsin Avenue was closed in Georgetown Thursday afternoon because of a partial building collapse and gas leak.
The collapse set off burglar alarms at neighboring businesses in the 1400 block of Wisconsin Avenue NW.
First-responders found the windows knocked out at 1422 and 1424 Wisconsin Ave., D.C. Fire and EMS reported. They also smelled gas.
The ceiling collapsed on the first floor of the 19th-century storefront, which is being renovated.
The 1400 block of Wisconsin Avenue was closed for hours but reopened before 8:30 p.m.
Gas to both affected addresses was shut off.
Businesses in the area were evacuated. Most were closed for the holiday, but at least one shoe store had planned to open at midnight for Black Friday.
No injuries were reported.
D.C. Fire and EMS originally reported an explosion at the location.
