Is 4623 6 Avenue, Brooklyn in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since January 31, 2017. 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 4623 6 Avenue, Brooklyn have active DOB violations?

Yes. 15 active DOB violations, most of them for low-pressure boilers. The newest was issued June 30, 2023. 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 4623 6 Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened May 16, 2024, awarded for $250. 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.

When was the boiler at 4623 6 Avenue, Brooklyn last inspected?

It has 2 boilers, both inspected in 2025, the latest on October 23.

Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

Is 4623 6 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 4623 6 Avenue, Brooklyn built?

How many apartments does 4623 6 Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 4623 6 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, DOB boiler inspection reports 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, DOB boiler inspection reports 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.
