The fire on the 400 block of E. Bellefonte Avenue was first reported just before 10 p.m. Arriving firefighters encountered heavy fire and sounded a second alarm.
The fire has since been extinguished, though a large emergency response remains on scene.
No injuries were reported. The Alexandria fire union said via Twitter that the fire is believed to have broken out in a dryer.
“Fire began in a dryer and extended through the walls into the cockloft area,” IAFF Local 2141 said via Twitter. “Crews worked quickly to keep the fire from spreading to multiple units.”
