Is 439 Rear West 50 Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 12 open Class C, with 2 certifications filed and 2 new Class C in the last 180 days, too few to call a direction. 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 439 Rear West 50 Street, Manhattan?

Since September 28, 2023, certifications were filed on 19 Class C violations: 16 by the original certify-by date, 3 after it. HPD now marks 1 of them False Certification. 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 439 Rear West 50 Street, Manhattan in housing court?

Yes. 1 open housing court case, opened March 4, 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 439 Rear West 50 Street, Manhattan?

Yes. 1 DOB complaint in the last 12 months. It was filed January 30, 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 DOB work permits in effect at 439 Rear West 50 Street, Manhattan?

Yes. 2 DOB work permits in effect. The latest, for Plumbing work, was issued January 29, 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.

Is 439 Rear West 50 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.

When was 439 Rear West 50 Street, Manhattan built?

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 housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits 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 HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB NOW work permits 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.
