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
Tenant-reportedNo 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.
| Winter | DaysDays with complaints | Complaints | Violations |
|---|---|---|---|
| 2025–26 | 0 | 0 | 0 |
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 filingThe 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.

Complaints to the city
Public complaintComplaints 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.
No complaints from this building in the last three years. Worth knowing what that does and does not mean: tenants who expect nothing to happen often stop calling.
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 17 Dec 2008
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 filingAssociations 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
91 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 has 5 open hazardous violations on this building. Ask which apartments they concern and what has been done since.
- 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 6 open housing violations: 0 immediately hazardous, 5 hazardous and 1 non-hazardous. Paperwork filings, such as a late registration, are not counted.
On 4 Dec 2018. 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.
No heat or hot-water complaints or violations were recorded here in the 2025–26 heat season.
No residential evictions by a city marshal are recorded here since 2017.
Not yet. Reviews come from people who lived here, and none has been published for this building.
