Questions about this building

Does 1639 Nelson Avenue, Bronx have open violations?

Yes. 1639 Nelson Avenue, Bronx had 40 open violations on September 26, 2026: 40 from HPD. 19 are Class C, the class HPD treats as immediately hazardous.

Is 1639 Nelson Avenue, Bronx getting better or worse?

Open violations are sitting, with little movement either way. 19 open Class C, with 0 certifications filed and 3 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 1639 Nelson Avenue, Bronx?

Since September 28, 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.

Are any HPD emergency repair orders at 1639 Nelson Avenue, Bronx marked completed?

Yes. 2 completed HPD emergency repair orders since September 28, 2023, awarded for $782 in total. The most recent of the 2, a general construction order, was opened April 21, 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.

When was 1639 Nelson Avenue, Bronx built?

The city's record gives 1931 as the year 1639 Nelson Avenue, Bronx 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 2 floors.

How many apartments does 1639 Nelson Avenue, Bronx have?

The Department of City Planning's PLUTO tax-lot file lists 6 residential units at 1639 Nelson Avenue, Bronx. 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 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 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.
