Out Like a Light by Laurence M. Janifer

The building was just off Amsterdam, in the Eighties. It had been a shining new development once, but it was beginning to slide downhill now. The metal on the windowframes was beginning to look worn, and the brickwork hadn't been cleaned in a long time. Where chain fences had once protected lonely blades of grass, children, mothers and baby carriages held sway now, and the grass was gone. Instead, the building was pretty well surrounded by a moat of sick-looking brown dirt.

Malone went into the first building and checked the name against the mailboxes there, trying to ignore the combined smells of sour milk, red pepper and here and there a whiff of unwashed humanity.
