Concern level1 of 4
Low

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 18 stabilized units with New York State for 2018 — essentially all of the building's 6 apartments.

421-a tax benefit · expires ~2033

A 421-a building's rent stabilization is tied to this tax benefit and generally ends when it expires — here, around 2033 (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.
