Questions about this building

Does 1734 St Johns Place, Brooklyn have open violations?

Yes. 1734 St Johns Place, Brooklyn had 49 open violations on September 26, 2026: 46 from HPD and 3 from OATH/ECB. 10 are Class C, the class HPD treats as immediately hazardous.

Is 1734 St Johns Place, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 23 certifications filed against 8 new Class C in the last 180 days. That window ends September 26, 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 1734 St Johns Place, Brooklyn?

Since September 28, 2023, certifications were filed on 27 Class C violations, all 27 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 1734 St Johns Place, Brooklyn have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for November 18, 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.

Is 1734 St Johns Place, Brooklyn in housing court?

Yes. 2 open housing court cases, most of them heat and hot water cases. The newest opened August 21, 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 1734 St Johns Place, Brooklyn?

Yes. 3 DOB complaints in the last 12 months. The newest was filed August 26, 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 1734 St Johns Place, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 28, 2023: a plumbing order, opened February 11, 2026, awarded for $8,500. 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.

Is 1734 St Johns Place, 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 1734 St Johns Place, Brooklyn built?

The city's record gives 2010 as the year 1734 St Johns Place, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 5 floors.

How many apartments does 1734 St Johns Place, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 18 residential units at 1734 St Johns Place, 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, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders and the city's PLUTO tax-lot file. 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.

Sources. HPD housing violations and OATH/ECB hearing results, plus OATH hearing dates, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders 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.
