Is 3990 10 Avenue, Manhattan getting better or worse?
Certifications are being filed faster than new violations come in. 12 certifications filed against 4 new Class C in the last 180 days. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.
When were certifications filed on Class C violations at 3990 10 Avenue, Manhattan?
Since September 28, 2023, certifications were filed on 2 Class C violations, all 2 by the original certify-by date. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice. A granted postponement moves that date and the city's data keeps only the first, so a certification counted after it may still have met a postponed date.
Is 3990 10 Avenue, Manhattan in housing court?
Yes. 1 open housing court case, opened January 15, 2026. HPD takes buildings to housing court to get violations fixed and heat and hot water restored, and it joins tenants' own repair cases, called tenant actions. A case stays open until the court closes it.
Has DOB received complaints about 3990 10 Avenue, Manhattan?
Yes. 2 DOB complaints in the last 12 months. The newest was filed January 30, 2026. Anyone can complain to DOB about a building or the work going on in it, and DOB then inspects and decides whether there is a violation. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.
Are any HPD emergency repair orders at 3990 10 Avenue, Manhattan marked completed?
Yes. 3 completed HPD emergency repair orders since September 28, 2023, awarded for $1,775 in total. The most recent of the 3, a general construction order, was opened March 4, 2026. HPD orders an emergency repair when a hazardous condition cited in a violation, or in another agency's emergency order, is not corrected, and does the work itself or through a contractor. The amounts are what the orders were awarded for, not a bill: this page does not show what was charged to the property or whether it was paid. Orders for lab tests, such as dust-wipe and asbestos samples, are not counted.
Is 3990 10 Avenue, Manhattan rent stabilized?
The building has rent-stabilized apartments on its 2024 registration. That comes from the Rent Guidelines Board's list of buildings with at least one stabilized apartment registered that year. Buildings that registered late are left off, and a 421-a or J-51 building can leave stabilization when its tax benefit ends. A particular apartment's status is for NYS HCR to say.

This page is current through September 26, 2026. The city's data changes daily, so a violation certified after that can still show as open here; the city's own page for this building is linked above.
