Questions about this building

Does 110 Martense Street, Brooklyn have open violations?

Is 110 Martense Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 5 open Class C, with 1 certification filed and 0 new Class C in the last 180 days, too few to call a direction. 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 110 Martense Street, Brooklyn?

Since October 12, 2023, certifications were filed on 5 Class C violations, all 5 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 110 Martense Street, Brooklyn have active DOB violations?

Yes. 1 active DOB violation, issued October 25, 1994. 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 110 Martense Street, Brooklyn been in housing court?

Yes. 26 housing court cases here since 2005. 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.

When was the boiler at 110 Martense Street, Brooklyn last inspected?

On September 14, 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 110 Martense Street, Brooklyn last file its bedbug report?

On May 6, 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 110 Martense Street, 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 110 Martense Street, Brooklyn built?

The city's record gives 1927 as the year 110 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 4 floors.

How many apartments does 110 Martense Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 28 residential units at 110 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 DOF's tax lien sale lists, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, 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 DOF's tax lien sale lists, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, 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.
