Half a dozen University Park North residents voluntarily evacuated their apartments this morning when smoke could be seen and smelled coming from 145 Buckingham Way.

Fire alarms blared after firefighters were summoned to the SF State-owned complex around 5:20 a.m. but few residents left their apartments, according to firefighters on the scene.

Residents were able to return to their apartments at 5:40 a.m. after firefighters determined some burnt food on the second floor of the complex set off the smoke alarm, according to the firefighters.

The complex is a three-story, 12 unit building.
