How to read this map
Each value is the number of 311 vacant/abandoned-building complaints placed in a community area over the trailing window, divided by its parcels and scaled to 1,000. The ramp is warmand higher is worse — a dense cluster of complaints is a blight-and-disinvestment signal, not a neutral magnitude. Complaints are assigned by the City’s own community-area field on each request.
A note on sources. The City also publishes a vacant-buildings violations dataset, but it is effectively a historical archive — its enforcement activity peaked in 2011–2017, the wave of the foreclosure crisis, and it has recorded only a handful of cases since. To avoid implying that decade-old enforcement is current, this map uses the live 311 complaint stream instead; the historical violations remain a matter of record but are not shown here.
