An HPD certificate of correction: what happens after you file.
of the 2,756,334 Class A, B and C violations we hold have ever been certified corrected
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; the repair alone does not. After filing, a certification lands as NOV Certified On Time or NOV Certified Late, a rejected one as Invalid Certification, and one a reinspection contradicts as False Certification. Across Class A, B and C, the median from inspection to a filed 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 and comes up at sale, refinance and permit. 17,673 violations were certified late. Late is accepted, and the missed window stays visible.
If you clear violations for a living. 663,254 violations sit at NOV Sent Out with no later status and 90,547 carry Not Complied With. Each is a filing that has not happened. 21,271 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. 7,061 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
HPD records the outcome of a certificate of correction as the violation's status. Six statuses describe it. On time and late record the filing; invalid and false record a filing HPD rejected; the two postponement statuses, granted and denied, record a request to extend the window. After a filing, HPD mails the tenant a letter asking whether the repair was made, and CIV14 Mailed, on 25,264 violations, marks that letter going out.
| Status | Violations | What it records |
|---|---|---|
| NOV Certified On Time | 12,283 | filed inside the class window and accepted |
| NOV Certified Late | 17,673 | filed after the window and accepted; the missed window stays visible |
| Invalid Certification | 21,271 | filed and rejected on review |
| False Certification | 7,061 | filed, and a reinspection found the condition still there |
| Certification Postponment Granted | 2,430 | HPD extended the window on request |
| Certification Postponment Denied | 2,781 | an extension was requested and refused |
The same live counts as each status's own page in the glossary. 59.0% of the on-time and late certifications were late, and 48.6% of the violations whose status is a filing outcome were rejected or contradicted.
How long certification takes, by class
The class sets the correction window, and the notice sets a certify-by date after it for the certification: a median of 21 days from the inspection for Class C, 51 for Class B and 110 for Class A. Owners who certify file at a median of 16, 38 and 51 days, and 92.6%, 96.5% and 98.5% of them file by that date. The share that ever certifies is not ordered by urgency: Class B is the highest at 47.2% and Class A the lowest at 31.7%.
| Class | Window | Ever certified | Median days |
|---|---|---|---|
| C | 24 hours | 45.6% | 16 |
| B | 30 days | 47.2% | 38 |
| A | 90 days | 31.7% | 51 |
Median days runs from inspection to the filed 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 status moves on without the owner. Not Complied With marks the missed window: 90,547 violations carry it. For hazardous classes the civil penalty process can follow. 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 790 lead document submissions, 291 were accepted, 36.8%. 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 as the violation's status: 12,283 violations carry NOV Certified On Time and 17,673 NOV Certified Late.
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 taken; it lands as NOV Certified Late, and 59.0% of the on-time and late certifications are late ones.
Can HPD reject a certificate of correction?
Yes. 21,271 violations carry Invalid Certification and 7,061 carry False Certification, 48.6% of the violations whose current status is a certification outcome: on time, late, invalid or false. 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 shows what happens after filing. Nothing is filed through this site.
What the filing data 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 see one building's filings, use the form above or HPD Online.
