Questions about this building

Does 102 Martense Street, Brooklyn have open violations?

Yes. 102 Martense Street, Brooklyn had 24 open violations on October 10, 2026: 24 from HPD. 1 is Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 40 years, since December 29, 1985.

Is 102 Martense Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 1 open Class C, with nothing filed or new in the last 180 days. That window ends October 10, 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 102 Martense Street, Brooklyn?

Since October 12, 2023, certifications were filed on 3 Class C violations, all 3 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.

Does 102 Martense Street, Brooklyn have active DOB violations?

Yes. 3 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.

Has 102 Martense Street, Brooklyn been in housing court?

Yes. 3 housing court cases here since 2023. 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.

Are any HPD emergency repair orders at 102 Martense Street, Brooklyn marked completed?

Yes. 3 completed HPD emergency repair orders since October 12, 2023, awarded for $3,143 in total. The most recent of the 3, a general construction order, was opened September 25, 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.

When was the boiler at 102 Martense Street, Brooklyn last inspected?

On October 1, 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 102 Martense Street, Brooklyn last file its bedbug report?

On April 30, 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.

When was 102 Martense Street, Brooklyn built?

The city's record gives 1931 as the year 102 Martense Street, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up building with 5 floors.

How many apartments does 102 Martense Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 25 residential units at 102 Martense Street, 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/ECB summonses from DOB and FDNY, DOF's tax lien sale lists, DOB violations, HPD's housing court cases, 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 October 10, 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/ECB summonses from DOB and FDNY, DOF's tax lien sale lists, DOB violations, HPD's housing court cases, 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.
