One in 20 New York City addresses accounts for just over half of all 311 complaints since 2020.
Most of the busiest addresses get one kind of complaint over and over. The city's public 311 data does not say who files a complaint, so these counts say how often an address was named, not how many people named it. For the busiest ones, the timing of each complaint says something about how they were filed. Select an address to find it on the map.

And please read this AI caution. The question and the choice of source are the author's (a human). The data pull, the code and the page were done by Anthropic's Claude Code under close direction. Quality control on this project: the quarterly pulls were summed and matched to the city's own row count exactly; addresses were cleaned by written rules, with entries that name only a street, park or airport set aside and counted; the timing analysis was rerun on the full record for each address after an exact-match query was found to miss older records stored with doubled spaces; each agency's closing note was sorted into an outcome by written rules, and every note's assignment is published; and every number in the text on this page is computed from the published data files. The risks of using AI remain, and red flags are welcome.
