8,446 of 30,626 actively inspected New York City restaurants — 28 percent — have had a health inspector record evidence of mice (health-code violation 04L) within the current data window. Inspectors logged evidence of rats (violation 04K) at another 2,071 establishments. Every one of them is on the map above, plotted at its front door and carded with its latest sanitary grade.
This week (Sep 24–30): 14 restaurants closed by DOHMH, 6 reopened, 69 cited for mice. See the full list.

Ranked by share of restaurants with a 04L citation · ZIP codes with at least 40 actively inspected restaurants
Where does the data come from? Every point is drawn from the DOHMH New York City Restaurant Inspection Results dataset on NYC Open Data — the city's official record of health inspections. The map refreshes weekly and covers the rolling window (roughly the last three years) that the Health Department publishes.
What counts as "evidence of mice"? Violation code 04L, cited when an inspector personally observes live mice or signs of them — droppings, gnaw marks, nesting material — in the food or dining areas. It is one of the most common critical violations in New York City. Rats are a separate code, 04K, and are marked on each restaurant's slip here too.
Does a mice citation mean the restaurant is dirty today? Not necessarily. A citation can sit anywhere in the data window, and many restaurants fix the problem and go on to earn an A. That's why each dot also shows the establishment's most recent grade and inspection date — read the slip, not just the dot.
What does "Grade Pending" mean? A restaurant that scores 14 or more points on its initial inspection isn't graded on the spot; it is re-inspected a few weeks later. If the re-inspection lands in the B or C range, the restaurant can post a "Grade Pending" card instead of the letter while it contests the result at a hearing, and a restaurant reopening after a Health Department closure is issued Grade Pending too. On this map a Pending card replaces the letter the restaurant held before — the slip shows that last letter and its date. Grade Pending isn't a grade: it usually means the most recent inspection found problems in the B or C range and the final grade is still being decided.
What if a restaurant has been closed? When the Health Department's latest record for an establishment is a closure, the slip says so first, with the date, and the letter becomes its last letter grade. That is what the published records say — not proof that the place is shut today; reopenings are recorded too, and appear here when they are.
What's the "Food poisoning" view? A third way to look at the map, built from 311, not DOHMH: New Yorkers filed 9,340 311 "Food Poisoning" reports citywide in the last three years. These are complaints filed by the public — DOHMH investigates, but its findings on individual reports aren't published, so a report is not proof that a specific restaurant made anyone sick, only that someone called it in. Toggle to that view to see where reports cluster; a building's dot only turns dark when it has three or more reports. When a building holds more than one restaurant, a report shown on its slip is shared by all of them, never pinned to one.
What's the story of the building it's in? Every restaurant lives in a building with its own history — permits, violations, sales, owners, rodent inspections. Look any address up at Building Biography, the companion site built from 111 million NYC public records.
