On the NYC DHCR 2024 registered rent-stabilized building list. This official list records the building, not a per-year unit count.
421-a tax benefit · expires ~2034
A 421-a building's rent stabilization is tied to this tax benefit and generally ends when it expires — here, around 2034 (approximate, from DOF exemption records). Confirm your unit's status with NYS HCR.
No public data says which specific apartment is stabilized.
Registration counts apply to the building, not to unit numbers. To confirm your own apartment, request your rent history from New York State Homes and Community Renewal — it is free and takes a few weeks.
The owner owes enough in property taxes (and possibly water charges) to be listed for the city's tax-lien sale (most recently a 10-day notice). A listing can still be cured by paying or entering a payment plan.

From DOF lien-sale lists (2019–2025). Financial distress is not proof of neglect, but owners behind on what they owe the city more often let repairs slide. Debt may since have been paid.

NYPD complaints reported within about 1,000 ft (a few blocks) in the last year, by severity. This reflects what gets reported and where police are active as much as actual safety, and busier, denser, higher-foot-traffic blocks log more. Locations are approximate — the NYPD shifts each report to the nearest corner for privacy — so read this as rough context, not a safety score.

0112 open HPD violation(s)
How this is set: open hazardous violations measured against the building's size, then raised by strong distress signals — HPD's enforcement program, court harassment findings, recent evictions, unpaid DOB fines, open housing-court cases, and a sold tax lien. Neighborhood noise and crime are not part of it. It describes the public record, not the condition of any one apartment, and a quiet record is not proof of a good building.

311 noise complaints within about 1,000 ft (a few blocks) in the last year. Most reports here are about outdoor noise (mostly unspecified) — street life and traffic more than neighbors. This counts how often people call 311, which tracks how densely populated and busy an area is as much as how loud it is — it is not a sound measurement.
