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

This building is not on the state's list of buildings with rent-stabilized apartments for 2024. That is not proof none are: an owner who did not register is missing from the list too.

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.

Paperwork and notices1 open

The owner failed to file something the city requires, most often the annual property registration or the annual bedbug report. Real violations, and they say something about an owner, but not a condition anyone is living in. Kept out of the count at the top of this page for that reason.

  • Dept. rules and regs. provide a completed certificate of inspection visits in a proper frame at or near mailboxes, bottom edge of frame between 48-62 inches above floor frame missing.

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.

8 complaints in three years, 5 of them in the last twelve months.

  • Noise2 / 3
  • Doors and windows0 / 2
  • Mold and damp2 / 2
  • Leaks and plumbing1 / 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 7 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. There is 1 open mould violation on record. Ask to look behind furniture and under sinks, and ask what was done the last time; a repaint is not a repair.
  3. 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.
  4. This building dates from 1931 and has 5 open lead-paint violations on record. If a child under six will live here, ask what testing and remediation has been done and ask for it in writing.
  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.
