Concern level4 of 4

Severe

015 open class-C HPD violations (immediately hazardous) across 6 apartments
021 open rent-impairing violation(s)
0327 active DOB violation(s)
041 OATH/ECB 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 OATH/ECB 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

Not on the rent-stabilized list

Not found in the DOF tax-bill records nor the 2024 DHCR registered building list. Absence isn't proof a unit is unregulated — buildings can be missing or newly deregulated.

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.

HPD housing-maintenance violations

Open now

On record

Open Class C

Open Class B

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. HPD writes a separate violation for each room or spot, so one inspection can produce several near-identical entries; those are grouped below by apartment and date.

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.

Violation65

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

DOB building violations

Active

On record

Active, last 3 yrs

Violations issued by the Department of Buildings that the owner must correct. Most don't carry a fine on their own; summonses that go to a hearing and can be fined are listed separately under OATH/ECB.

DOB building violations

OATH/ECB violations and fines

Balance due (active)

Active violations

Lost by default

These are separate from DOB violations. They are summonses written by DOB inspectors and decided at a hearing before OATH, the city's administrative court (formerly the Environmental Control Board), and they can carry a fine. "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.

Evictions

No marshal-executed evictions on record for this building. Eviction cases filed in court but not carried out aren't included.

Evictions

Housing court: repair & harassment cases

No HPD housing-court cases on record for this building.

These are cases HPD is a party to, mostly tenants suing to force repairs or stop harassment. Eviction cases landlords file against tenants are not in the city's open data, so they don't appear here; the Evictions section shows only evictions a marshal carried out.

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 60-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.
