NYC HPD Violations Lookup for Any Building
Type an NYC address to see how many open class B and C HPD violations the building was issued in the past 24 months, how many are class C, and how that rate per apartment compares with other NYC buildings — plus open DOB complaints, heat complaints, bedbug filings and elevator inspections.
How to check HPD violations for an NYC building
HPD violations are public. There are two ways to look them up by address, and they answer different questions:
| Question | DwellCheck | HPD Online (hpdonline.nyc.gov) |
|---|---|---|
| Answers | Is this building worse than most? | What exactly is wrong, and where? |
| HPD violations | Count of open class B and C violations issued in the past 24 months, the class C count, and the rate per apartment | Every violation line — class A, B and C, open and closed — with its description and dates |
| Comparison | Rated against NYC buildings with 3+ apartments | None |
| Also in the same search | Open DOB complaints, 311 heat and other complaints, bedbug filings, elevator inspections, plus neighborhood checks | HPD complaints and the building's HPD registration |
How to read the count: most NYC buildings with 3 or more apartments have no open class B or C violation issued in the past 24 months. The top 10% have at least 0.33 per apartment, the top 5% at least 1, and the top 1% at least 4.4.
Searching DOB and 311 records too? The NYC building violation search guide shows which city portal holds which record. To read the full list on the city's own site, follow the step-by-step HPD Online search guide.
What We Check
Five checks make up the Building Health score, and a sixth, all 311 complaints at the building, is scored under Nuisance. Building Health can only subtract points, up to −67.

Frequently Asked Questions
How do I check if a NYC building has HPD violations?
Enter the building address on DwellCheck. The report shows how many open class B and C HPD violations were issued in the past 24 months (with the class C count and the rate per apartment compared with NYC buildings with 3+ units), open DOB complaints, 311 heat complaints and other 311 complaints at the building, bedbug filings that report infested units, and whether any elevator is overdue for inspection. It does not list closed or class A violations; HPD Online has the full record.
What is an HPD violation?
HPD violations are issued by NYC Housing Preservation & Development when buildings fail to meet housing code standards. Class A violations are non-hazardous, Class B are hazardous, and Class C are immediately hazardous conditions that must be corrected within 24 hours.
How recent is the building violation data?
DwellCheck queries NYC Open Data when a report is calculated and caches the result for up to 14 days; every report shows when it was calculated. The city datasets refresh on their own schedules: 311 service requests, HPD violations, DOB complaints and DOB NOW elevator records daily, and HPD bedbug filings monthly.
Can I see bedbug history for a building?
Partly. NYC landlords must file a bedbug report for each building every year. DwellCheck checks the filings from the past 24 months and shows how many infested units they report. The score counts infested units per apartment, so a building whose filings report zero infested units, or a small number for its size, gets no penalty. Older filings are not checked.
What should I do if a building has many violations?
Multiple open violations, especially Class B or C HPD violations, are red flags. Consider: 1) How quickly were past violations corrected? 2) Are violations recurring issues? 3) Are there recent complaints? A pattern of slow repairs or repeated issues suggests poor management.
How many HPD violations is a lot for an NYC building?
Compare per apartment, not the raw count. DwellCheck measured every NYC building with 3 or more apartments: most have no open class B or C HPD violation issued in the past 24 months. The top 10% have at least 0.33 open B/C violations per apartment, the top 5% at least 1, and the top 1% at least 4.4. The report tells you which of those groups a building falls in.
Are HPD violations public record?
Yes. HPD publishes every housing-code violation it issues. Anyone can search them by address on HPD Online (hpdonline.nyc.gov) or download them from the Housing Maintenance Code Violations dataset on NYC Open Data (wvxf-dwi5) — no account, and you do not need to be a tenant.
How do I look up NYC building violations by address?
Type the full street address (number + street + borough) into one of these portals: HPD Online at hpdonline.nyc.gov for housing violations, DOB BIS at a810-bisweb.nyc.gov for DOB and ECB/OATH violations, and the 311 Service Requests dataset on NYC Open Data for 311 complaints. Each portal returns a different slice. DwellCheck counts the open class B and C HPD violations and open DOB complaints for the address and rates the HPD count per apartment against NYC buildings with 3 or more units.
How do I find HPD violations on my building?
Go to hpdonline.nyc.gov and search your building number, street, and borough. The building page shows: (a) every Class A, B, and C violation issued, (b) issue and certification dates, (c) current open/closed status, and (d) the building's HPD registration contacts. Look for open Class C violations (immediately hazardous, 24-hour correction deadline) and recurring violations year-over-year — both are signs of a non-responsive landlord. DwellCheck shows how many open class B and C violations were issued in the past 24 months and how many are class C, but not the year-over-year history. For a screen-by-screen walkthrough, see the HPD complaint lookup guide.
How do I check DOB complaints in NYC?
DOB complaints (separate from HPD housing complaints) are listed on the building's DOB BIS profile at a810-bisweb.nyc.gov: search the address and open Complaints. Each shows its category, date entered, inspection disposition and whether it is still active. DwellCheck counts the complaints entered in the past 24 months that are still open, for every building on the lot. Recurring complaints at the same address suggest the issue is unresolved.
How do I find building violations in NYC for free?
Every NYC building violation search is free through official government portals — there is no charge for HPD Online, DOB BIS, NYC 311, ACRIS, or NYC Open Data. DwellCheck reports are also currently free; they save time by combining several of these sources into one report, but the underlying records cost nothing to access directly.
