New York’s most serious housing violations, counted live.
New York City publishes every housing maintenance violation it issues. The figures below are the immediately hazardous ones issued in the last three years, counted from the city’s open-data API when this page loads in your browser. Totals only, never an address or a name.
Counted from NYC Open Data when this page was built.
What the numbers are, and are not.
Every figure here is counted live from the city’s API. How the counts are built, and how every claim is graded.
Class C
Immediately hazardous conditions: no heat, no hot water, lead paint where a child lives, vermin, defective wiring. The city’s most serious housing class.
The last three years
Violations issued in the last three years. This is a count of what was issued, not a claim about what remains open today. Whether each one has been certified changes daily on the city’s side.
Totals only
Counts, never a list. This page names no building and no owner. The per-case work is what a firm receives in a brief.
Where our case files come from.
The same violations, borough by borough: the borough pages.
Our case files are built from these same city datasets. The newest data behind a brief:
- HPD violations through September 27, 2026
- OATH/ECB matters through September 24, 2026
- 2,945 case files in the current feed, each one through our build checks and claim gate
We started keeping our own copies of the city's data in July 2026. One reading is a snapshot; the copies we keep behind it are the history.

The counts above show the size of the problem. A brief is the part a firm can act on: named buildings, what is open on each, and the city page that shows it.
