Concern level4 of 4

Severe

017 open class-C HPD violations (immediately hazardous) — about 1 per 2 apartments
024 of those issued in the last 3 years
031 open rent-impairing violation(s)
047 active DOB violation(s)
051 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.

Rent regulation

Likely rent-stabilized

The owner registered 16 stabilized units with New York State for 2021 — essentially all of the building's 16 apartments.

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.

Open Class A

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 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.

Violation29

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 6 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

Flagged for the 2025 tax-lien sale

The owner owes enough in water and sewer 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.
