What do these labels mean?Where each of these comes from
- 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

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.

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.
Post a proper notice regarding rent stabilization law, in a form approved by the commissioner, in a conspicuous location within the common area at the buildings entrance. for more information about signage requirements, please visit: https://www.nyc.gov/site/hpd/services-and-information/required-signage.page

Court records
Court recordHousing 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.
1 case, all closed.
Heat and Hot Water
Opened 16 Jul 2013
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 DOB permits filed for this building in the last five years.
Annual bedbug report
Every multiple dwelling in New York must file this once a year. A report of zero infested units is good news. No report is not: failing to file is itself a violation.

What to ask at the viewing
561 Knickerbocker Avenue, Brooklyn, NY 11237
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.
- The city currently has 18 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.
- There were 3 heat or hot-water complaints here in the last twelve months. Ask who handles heat, how quickly it is usually restored, and whether the boiler has been replaced.
- There are 8 open mould violations on record. Ask to look behind furniture and under sinks, and ask what was done the last time; a repaint is not a repair.
- There were 2 pest complaints here in the last twelve months. 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.
- Ask what the deposit is, exactly what can be deducted from it, and how and when it comes back.
- 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.
Questions about this building
Yes. HPD lists 51 open housing violations: 18 immediately hazardous, 21 hazardous and 12 non-hazardous. Paperwork filings, such as a late registration, are not counted.
Since 2022, HPD inspectors have written the most violations here for walls and ceilings (32), fire and safety equipment (23) and doors and windows (19).
On 9 Sept 2026. HPD only publishes inspections that found something, so a later visit that found nothing would not show here.
The owner registered at least one rent-stabilized apartment here with the state for 2024. The list does not say which apartments. A tenant can ask the state for an apartment's rent history to be sure.
In the 2025–26 heat season the city received heat or hot-water complaints on 4 days, and HPD issued 0 heat violations.
City marshals carried out 1 residential eviction here since 2017. The record says nothing about why, and most follow a case for unpaid rent.
Not yet. Reviews come from people who lived here, and none has been published for this building.
