Does 4 Vernon Avenue, Brooklyn have active DOB violations?
Yes. 5 active DOB violations, most of them for low-pressure boilers. 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 4 Vernon Avenue, Brooklyn marked completed?
Yes. 3 completed HPD emergency repair orders since September 28, 2023, awarded for $2,135 in total. The most recent of the 3, a general construction order, was opened March 16, 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.
Does 4 Vernon Avenue, Brooklyn have a certificate of occupancy?
Its latest certificate of occupancy is a final one, issued July 6, 2020. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.
Is 4 Vernon 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 4 Vernon Avenue, Brooklyn built?
The city's record gives 1931 as the year 4 Vernon Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 5 floors.

Where do these numbers come from?

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.
