8 PM UPDATE: According to the fire department’s media-info line, this fire did $40,000 damage to one apartment and a hallway on the building’s third floor; investigators say it’s accidental, caused when combustible items were left too close to a hot-water heater. A woman and three children were living in the apartment and the Red Cross is helping them find someplace else to stay. No one was hurt. 12:58 PM UPDATE: Video clip showing the scene. Again, not a big incident, but certainly affected dozens of residents.

11:58 AM UPDATE: Just back with pix (and video to come). No visible smoke or flames from outside; firefighters have been working on ventilating the roof to clear out smoke that’s reportedly inside the building. No word about injuries, or extent of damage.

Scanner communication suggests some road blocking in that area, so stay away if you can. Map:
