Questions about this building

Does 5103 5 Avenue, Brooklyn have open violations?

Yes. 5103 5 Avenue, Brooklyn had 102 open violations on September 27, 2026: 5 from OATH/ECB and 97 from HPD. 19 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 35 years, since March 20, 1991.

Is 5103 5 Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 19 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.

When were certifications filed on Class C violations at 5103 5 Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 6 Class C violations: 1 by the original certify-by date, 5 after it. 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.

Does 5103 5 Avenue, Brooklyn have an OATH hearing coming up?

Yes. 2 hearings scheduled on DOB summonses, the first on October 7, 2026. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.

Does 5103 5 Avenue, Brooklyn have active DOB violations?

Yes. 11 active DOB violations, most of them for construction. The newest was issued October 24, 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.

Is 5103 5 Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened February 25, 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 5103 5 Avenue, Brooklyn?

Yes. 13 DOB complaints in the 12 months to September 25, 2026. The newest was filed August 12, 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 5103 5 Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened July 15, 2025, awarded for $3,000. 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.

Are any DOB work permits in effect at 5103 5 Avenue, Brooklyn?

Yes. 1 DOB work permit in effect, for Sidewalk Shed work, issued August 13, 2026. A permit in effect allows the work it names. It does not mean the work has started or finished, or that it fixes any violation on this page.

When was the boiler at 5103 5 Avenue, Brooklyn last inspected?

On April 13, 2026. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

When did 5103 5 Avenue, Brooklyn last file its bedbug report?

Its 2 buildings had all filed by March 19, 2026, for the year to October 31, 2025. HPD asks the owner of every building with 3 or more apartments for this report once a year, covering November 1 to October 31, including buildings that had no bedbugs.

Is 5103 5 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 5103 5 Avenue, Brooklyn built?

The city's record gives 1931 as the year 5103 5 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 3 floors.

How many apartments does 5103 5 Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 6 residential units at 5103 5 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 OATH hearing dates, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug 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 OATH hearing dates, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug 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.
