Is 243 East 123 Street, Manhattan getting better or worse?

New violations are coming in faster than certifications are filed. 38 new Class C against 0 certifications 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 243 East 123 Street, Manhattan?

Since September 29, 2023, a certification was filed on 1 Class C violation, after 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.

Is 243 East 123 Street, Manhattan in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since February 2, 2026. HPD puts a group of buildings with serious, long-running violations into the program each year. While a building is in it, HPD can make repairs itself and charge the cost to the property, and the building stays in until HPD discharges it.

Does 243 East 123 Street, Manhattan have active DOB violations?

Yes. 7 active DOB violations. The newest was issued September 2, 2020. 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 243 East 123 Street, Manhattan in housing court?

Yes. 4 open housing court cases. The newest opened August 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.

Has DOB received complaints about 243 East 123 Street, Manhattan?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed October 30, 2025. 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 243 East 123 Street, Manhattan marked completed?

Yes. 2 completed HPD emergency repair orders since September 29, 2023, awarded for $3,487 in total. The most recent of the 2, a general construction order, was opened October 12, 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 243 East 123 Street, Manhattan last inspected?

On March 6, 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 243 East 123 Street, Manhattan last file its bedbug report?

Is 243 East 123 Street, 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 243 East 123 Street, Manhattan built?

The city's record gives 1900 as the year 243 East 123 Street, 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 243 East 123 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 10 residential units at 243 East 123 Street, 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 HPD's Alternative Enforcement Program list, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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 HPD's Alternative Enforcement Program list, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, 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.
