What do these labels mean?
Tenant-reported
A resident's firsthand account of living here, moderated before it publishes, and labelled with whether we verified they lived there.
Official violation
A city inspector visited and recorded a code violation. HPD's own words, and its own hazard class.
Public complaint
A complaint somebody made to a city system, through HPD or 311. A report, not a finding: nobody has necessarily inspected it.
Public filing
A permit, a registration, a bedbug report: a document the owner filed with the city because the law requires it.
Court record
A Housing Court case HPD brought against the owner, or an eviction a city marshal carried out. A court's record: a case is an allegation until it ends in a finding.
Insufficient data
Not enough current information here to infer a pattern either way.

Tenant reviews

Tenant-reported

No tenant reviews yet. Lived here? Be the first.

Nothing above this section came from a tenant. It is all filed by the city, which means it only holds what somebody reported and an inspector wrote down, not what it is actually like to live here.

Not open yet. Reviews open when this neighbourhood does.

Heat season

No heat or hot-water complaints or violations were recorded here last winter (2025–26). That is the city's record: it only holds what somebody reported.

WinterDaysComplaintsViolations
2025–26000

The rules, 1 October to 31 May: from 6am to 10pm, when it is below 55°F outside, the apartment must be at least 68°F; overnight it must be at least 62°F whatever the weather. Hot water must be at least 120°F all year. A tenant without heat can report it to 311.

Rent stabilization

Public filing

The owner registered at least one rent-stabilized apartment here with the state for 2024. The list does not say which apartments, or how many.

Source: Rent Guidelines Board building list, from the state's 2024 registrations. To know about one apartment, a tenant can ask the state for its rent history through Ask HCR.

8 closed violations, plus 4 closed paperwork filings

Closed means HPD recorded the violation as corrected, or dismissed it. Both appear here, because the difference matters and only HPD’s own status line says which it was.

Complaints to the city

Public complaint

Complaints are reports made to the city. They are not confirmed findings. They come from HPD and from 311, and the same problem can appear more than once if more than one neighbour called.

1 complaint in three years, 1 of them in the last twelve months.

  • Noise1 / 1

Last twelve months / last three years. The solid part of each bar is the last twelve months.

Court records

Court record

Housing Court cases

Cases the city’s housing department (HPD) brought against the owner, usually to force repairs or restore heat. A case is an allegation; where the court recorded an outcome, it is shown.

No HPD Housing Court cases on record for this building.

Evictions

Residential evictions carried out by a city marshal since 2017. Most follow a case for unpaid rent, so a count here is not by itself a finding about the building or the landlord. We show how many, never which apartment.

No marshal evictions recorded at this building since 2017.

Ownership and management

Public filing

Associations come from registration records and may be incomplete. Owners register with HPD once a year, so a change of hands can go unrecorded for a full cycle.

What to ask at the viewing

Drawn from this building’s record above. They are questions, not conclusions: the point is to find out, in the twenty minutes you get inside, what the public record cannot tell you.

  1. The city currently has 12 open immediately-hazardous violations on this building. Ask which apartments they concern, how many are in the one you would be renting, and when HPD re-inspects.
  2. The owner has filed a bedbug report for this building (most recently for the year ending 2025). Ask when the building was last treated, how often an exterminator comes, and whether treatment covers the whole line of apartments or only the one that complained.
  3. 1 active construction permit on file. Ask what is being done, on which floors, and until when, and whether it affects heat, water or the elevator.
  4. Leaks and plumbing come up on this building's record. Ask which apartments were affected and whether the cause was ever found: 0 complaints in the last twelve months.
  5. Ask what the deposit is, exactly what can be deducted from it, and how and when it comes back.
  6. Ask who to call when something breaks, what happens after hours and at weekends, and how long a repair normally takes.

Ask for anything that matters in writing; an email after the viewing is enough. We are not your lawyer and this is not legal advice.
