An HPD violation is a Notice of Violation the NYC Department of Housing Preservation & Development issues when a home breaks the Housing Maintenance Code. HPD rates each one Class A (non-hazardous), B (hazardous) or C (immediately hazardous). Search NYC HPD violations on any building free above, by ZIP, BIN, Registration No. or Borough/Block/Lot, using the same live city data as HPD Online.
HPD records are filed by Borough, Block, and Lot (BBL), the city's ID for each tax lot. To look up a building by its street address, get the BBL first. It takes about 30 seconds.
Don't know the BBL? Search the ZIP code instead and scan the results for the street name.
HPD is the New York City Department of Housing Preservation & Development — the agency that enforces the housing maintenance code on every residential building in NYC. When an HPD inspector finds a code violation (peeling lead paint, no heat, mold, broken plumbing, etc.), they issue a Notice of Violation (NOV) that becomes public record.
HPDOnline (hpdonline.nyc.gov) is the city's official portal for looking up those NOVs. It works, but it is slow, requires you to know the exact borough and house number, and gives no context on what the violation means or what fixing it costs. Our HPD Lookup uses the exact same NYC Open Data dataset (wvxf-dwi5) and adds:
Minor conditions such as small plaster cracks or a missing peephole. The owner must correct it and certify the correction with HPD.
