Concern level4 of 4

Severe

0121 open class-C HPD violations (immediately hazardous) across 35 apartments
0217 of those issued in the last 3 years
032 open rent-impairing violation(s)
042 active DOB 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.

Rent regulation

Likely rent-stabilized

The owner registered 35 stabilized units with New York State for 2023 — essentially all of the building's 35 apartments.

2018 — 35 units registered2023 — 35

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.

Class C is immediately hazardous, Class B is hazardous, Class A is non-hazardous. A violation stays open until HPD certifies the repair, so some open items may already be fixed.

Complaints record what a tenant reported, not a finding by the city. "Closed" often means the inspector could not gain access.

311 noise complaints within about 1,000 ft (a few blocks) in the last year. Most reports here are about noise from inside buildings — neighbors, not the street. 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.

Violation76

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.

Neighborhood crime

Bedbug history

No bedbugs reported

The owner filed 7 annual bedbug reports and reported no infested units. Filing with zero infestations is the compliant, reassuring case.

Executed by a city marshal. An eviction can be lawful; a high or rising count is a displacement signal, not proof of wrongdoing.

With a judgment

Most cases are tenants taking the owner to court to force repairs. A case is not proof of wrongdoing; a harassment finding or judgment is a court ruling against the owner.

Unpaid city fines

Balance due (active)

Active violations

Lost by default

DOB violations adjudicated by OATH carry money penalties. "Lost by default" means the owner never appeared at the hearing. An unpaid balance is a stronger "ignoring the city" signal than a raw violation count.

City debt & tax-lien sale

Not on the city's tax-lien sale list (2019–2025). The owner has not fallen far enough behind on property tax or water charges to be flagged for a lien sale.
