Is 347 Convent Avenue, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 2 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 347 Convent Avenue, Manhattan?

Since October 12, 2023, a certification was filed on 1 Class C violation, 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 347 Convent Avenue, Manhattan have active DOB violations?

Yes. 2 active DOB violations, most of them for landmarks. The newest was issued October 31, 2000. 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 347 Convent Avenue, Manhattan in housing court?

Yes. 1 open housing court case, opened May 18, 2026. 5 housing court cases here since 2005, most of them tenant actions. 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 347 Convent Avenue, Manhattan marked completed?

Yes. 2 completed HPD emergency repair orders since October 12, 2023, awarded for $2,490 in total. The most recent of the 2, a general construction order, was opened August 13, 2024. 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 347 Convent Avenue, Manhattan last inspected?

On April 17, 2025. 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 347 Convent Avenue, Manhattan last file its bedbug report?

On December 12, 2025, 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 347 Convent Avenue, Manhattan 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 347 Convent Avenue, Manhattan built?

The city's record gives 1890 as the year 347 Convent Avenue, Manhattan 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 347 Convent Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 347 Convent Avenue, Manhattan. 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, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. 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, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports, the city's PLUTO tax-lot file and DOF's property sales records. 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.
