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.

Paperwork and notices6 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.

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.

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.
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.
Filings
Public filingBuilding permits
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.

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
565 Onderdonk Avenue, Ridgewood, NY 11385
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 3 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.
- 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.
- 6 open violations for not filing something the city requires, usually the annual registration or the annual bedbug report. Nothing anyone lives in, but it is the record's plainest measure of whether this owner follows through.
- 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 9 open housing violations: 3 immediately hazardous, 0 hazardous and 6 non-hazardous. Paperwork filings, such as a late registration, are not counted.
Since 2022, HPD inspectors have written the most violations here for heat and hot water (1).
On 13 Sept 2024. 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.
