Questions about this building

Is 351 Lenox Avenue, Manhattan getting better or worse?

New violations are coming in faster than certifications are filed. 9 new Class C against 1 certification filed 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 351 Lenox Avenue, Manhattan?

Since September 29, 2023, certifications were filed on 2 Class C violations, all 2 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 351 Lenox Avenue, Manhattan have active DOB violations?

Yes. 1 active DOB violation, 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.

Is 351 Lenox Avenue, Manhattan in housing court?

Yes. 1 open housing court case, opened May 6, 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.

Are any HPD emergency repair orders at 351 Lenox Avenue, Manhattan marked completed?

Yes. 3 completed HPD emergency repair orders since September 29, 2023, awarded for $2,288 in total. The most recent of the 3, a general construction order, was opened February 26, 2026. 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 351 Lenox Avenue, Manhattan?

Yes. 3 DOB work permits in effect. The latest, for Sidewalk Shed work, was issued September 8, 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 351 Lenox Avenue, Manhattan last inspected?

On March 11, 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 351 Lenox Avenue, Manhattan last file its bedbug report?

Its 3 buildings had all filed by December 9, 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 351 Lenox 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 351 Lenox Avenue, Manhattan built?

The city's record gives 1910 as the year 351 Lenox Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 5 floors.

How many apartments does 351 Lenox Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 26 residential units at 351 Lenox 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 DOB violations, HPD's housing court cases, 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 DOB violations, HPD's housing court cases, 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.
