An HPD certificate of correction: what the record shows after you file.
of the 2,712,581 Class A, B and C violations on HPD's record have ever been certified corrected, as of September 9, 2026
See what is open on one building.
An HPD certificate of correction is the owner's sworn statement that a cited condition has been fixed, filed with HPD for each violation once the work is done. It is the only thing that moves a violation from open to certified on the public record; the repair alone does not. The record shows what happens after filing: an accepted certification lands as NOV Certified On Time or NOV Certified Late, a rejected one as Invalid Certification, and a filing a reinspection contradicts as False Certification. Across the three hazard classes the median from inspection to an accepted certification is 28 days.
If you own or manage the building. Correcting the condition is half the job. Until the certificate is filed and accepted, the violation stays open on the record and surfaces at sale, refinance and permit. 17,274 violations on the record were certified late; late is accepted, and the missed window stays visible on the file.
If you clear violations for a living. 658,546 violations sit at NOV Sent Out with no later status and 89,127 carry Not Complied With. Each is a filing that has not happened. 20,888 more were filed and rejected, which is work to redo, not work to start.
If you rent here. A certification is the owner's statement, checked by reinspection only some of the time. 7,099 violations carry False Certification, where the inspector came back and the condition was still there. A certified violation is not proof the repair held.
Where a filing lands on the record
HPD records the outcome of a certificate of correction as a status on the violation's row. Six statuses describe it. On time and late are both accepted; invalid and false are not; the two postponement statuses record a request to extend the window.
| Status | Violations | What it records |
|---|---|---|
| Nov Certified On Time | 8,716 | filed inside the class window and accepted |
| Nov Certified Late | 17,274 | filed after the window and accepted; the missed window stays visible |
| Invalid Certification | 20,888 | filed and rejected on review |
| False Certification | 7,099 | filed, and a reinspection found the condition still there |
| Certification Postponment Granted | 2,417 | HPD extended the window on request |
| Certification Postponment Denied | 2,804 | an extension was requested and refused |
Live counts as of September 9, 2026, the same counts on each status's own page in the glossary. 66.5% of accepted certifications were late; 51.8% of every filing the record shows was rejected or contradicted.
How long certification takes, by class
The window is set by the class and the record measures what owners actually do against it. Class C, with a 24-hour window, certifies at a median of 16 days; Class B, with 30 days, at 38; Class A, with 90 days, at 51. The share that ever certifies is not ordered by urgency: Class B is the highest at 47.2% and Class A the lowest at 31.5%.
| Class | Window | Ever certified | Median days |
|---|---|---|---|
| C | 24 hours | 45.6% | 16 |
| B | 30 days | 47.2% | 38 |
| A | 90 days | 31.5% | 51 |
Median days runs from inspection to the accepted certification over the violations in that class that carry one. What each class means is on the violation classes guide.
When nothing is filed
The certify-by date passes and the record moves on without the owner. Not Complied With marks the missed window: 89,127 violations carry it. For hazardous classes the civil penalty process follows, and CIV14 Mailed, on 17,654 violations, is the record of that letter going out. The way back is the same filing: a late certification is accepted and moves the status to NOV Certified Late.
Lead paint: the one category with a document review
HPD reviews the paperwork behind a lead paint certification separately from every other category, and records the result as its own status. Of 770 lead document submissions on the record, 274 were accepted, 35.6%. The rest went back. The lead paint guide carries the abatement record behind that number.
Common questions about the HPD certificate of correction
What is an HPD certificate of correction?
The owner's sworn statement to HPD that the cited condition has been corrected, filed for each violation after the work is done. HPD records the result on the violation's row: 8,716 violations carry NOV Certified On Time and 17,274 NOV Certified Late as of September 9, 2026.
How long do I have to file it?
The class window: 90 days for Class A, 30 for Class B, 24 hours for Class C, counted from the date the Notice of Violation is mailed. A late filing is still accepted; it lands as NOV Certified Late, and 66.5% of accepted certifications on the record are late ones.
Can HPD reject a certificate of correction?
Yes. 20,888 violations carry Invalid Certification and 7,099 carry False Certification, 51.8% of every certification the record shows filed. A rejected filing leaves the violation open; a false one, where reinspection found the condition, is the one that draws penalties.
Does this site file a certificate of correction?
No. A certification is filed with HPD directly, on paper or through HPD's own online system. This page reads the public record of what happens after filing. Nothing here files, represents, or advises.
What this record does not tell you
It does not show the certification form, the date the work was done, or who did it. It does not show whether a certified condition stayed fixed, beyond the reinspections that produced a False Certification. It names no building and no owner. To read one building's own filings, use the form above or HPD Online.
