59.7% of NYC properties with an open Class C violation have another matter open with the city.
On September 24, 2026, 35,864 New York City properties had at least one open Class C violation, the class HPD treats as immediately hazardous. 21,412 of them, 59.7%, also had at least one of four other open matters: an OATH hearing ahead on a DOB summons, a housing court case, active DOB violations, or a vacate order in effect.
Each record, counted the way the building page shows it
Every share below is of the same 35,864 properties. A property counts once however many of a record it has, and one property can appear in several rows, so the rows do not add up.
| Also has | Properties | Share |
|---|---|---|
| An OATH hearing ahead on a DOB summons pending, with a hearing date on or after September 24, 2026 | 3,074 | 8.6% |
| An open housing court case HPD's pending cases; harassment claims and CONH cases left out | 3,787 | 10.6% |
| Active DOB violations what DOB itself marks active | 19,177 | 53.5% |
| An HPD vacate order in effect for the whole building or part of it | 1,668 | 4.7% |
Rent stabilization is a different kind of fact
19,406 of the 35,864, 54.1%, have rent-stabilized apartments on their registration, by the Rent Guidelines Board's list. That is not an open matter with the city, so it is not in the four above. It says the building has such apartments. It does not say which ones, or whether a particular apartment is stabilized; that is for NYS HCR to say.
What these counts do not say
They do not say one record caused another, or that the same condition sits behind them. A housing court case can concern a different apartment from the Class C violation, and a DOB violation can concern a boiler or an elevator. A pending case or hearing is not a finding. A property here is a tax lot, which can hold more than one building. And HPD's file lags the inspector by days to weeks, so the newest cases are under-counted.
What it means for one building
A share is not a forecast for any one building. Each building's page shows every one of these records in its own row, dated, so looking one up answers which of them it has.

How this is counted
A property is a tax lot (BBL). It counts when HPD's own status marks at least one of its Class C violations open and that violation was inspected on or after September 27, 2023, the three-year window the building pages use. Each other record is counted the way the building page shows it: OATH hearings on DOB summonses still pending with a hearing date on or after the as-of date; HPD housing court cases still pending, harassment claims and CONH cases left out; DOB violations DOB marks active; HPD vacate orders still in effect; and the Rent Guidelines Board's list of buildings with rent-stabilized apartments on their registration. Every count was taken twice, from the rows behind the building pages and by a database query, and the two agree.
