Open violations are sitting, with little movement either way. 31 open Class C, with nothing filed or new in the last 180 days. That window ends September 27, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

Is 4420 3 Avenue, Brooklyn in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since February 1, 2021. HPD puts a group of buildings with serious, long-running violations into the program each year. While a building is in it, HPD can make repairs itself and charge the cost to the property, and the building stays in until HPD discharges it.

Does 4420 3 Avenue, Brooklyn have active DOB violations?

Yes. 9 active DOB violations. The newest was issued November 14, 2025. The Department of Buildings writes these separately from HPD's housing violations, for things like boilers, elevators, facades, construction and energy filings. Each one stays active until DOB resolves or dismisses it.

Are any HPD emergency repair orders at 4420 3 Avenue, Brooklyn marked completed?

Yes. 6 completed HPD emergency repair orders since September 29, 2023, awarded for $12,714 in total. The most recent of the 6, a general construction order, was opened July 22, 2025. 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 4420 3 Avenue, Brooklyn 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.

When was 4420 3 Avenue, Brooklyn built?

The city's record gives 1922 as the year 4420 3 Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a residence with stores or offices with 4 floors.

How many apartments does 4420 3 Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 6 residential units at 4420 3 Avenue, Brooklyn. The count is for the whole tax lot.

Where do these numbers come from?

From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on HPD's Alternative Enforcement Program list, DOB violations, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders and the city's PLUTO tax-lot file. This page is current through September 27, 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.

Sources. HPD housing violations and OATH/ECB hearing results, plus HPD's Alternative Enforcement Program list, DOB violations, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders and the city's PLUTO tax-lot file. Counts cover HPD Class B and C violations from the last 3 years that HPD still shows open, and OATH/ECB summonses from the same 3 years that the city still shows active. The city's own pages can show more, never fewer.
