Concern level3 of 4

High

015 open class-C HPD violations (immediately hazardous) — about 1 per 14 apartments
023 of those issued in the last 3 years
0310 active DOB violation(s)
041 DOB fine lost by default (unpaid)

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.

Likely rent-stabilized

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.

311 noise complaints within about 1,000 ft (a few blocks) in the last year. Most reports here are about outdoor noise (mostly residential) — 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.

Violation55

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 8 annual bedbug reports and reported no infested units. Filing with zero infestations is the compliant, reassuring case.

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.

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.
