Every figure on this site is read from a public dataset published by a New York City or New York State agency. Nothing is scraped from behind a login, bought from a data broker, or estimated where a record exists. This is the list of who publishes what, grouped by the agency rather than by dataset id — because "DOB, and here is what DOB gives us" is something you can check, and thirty-six Socrata resource ids is not.
NYC Department of Buildings — DOB and DOB NOW
Violations, complaints, permit issuance and job filings, elevator, boiler, facade (FISP) and cooling-tower records, and certificates of occupancy. DOB runs two systems: the legacy Buildings Information System and DOB NOW, which replaced it for new filings, and both are read because neither holds the whole history. Record links open the city's own BIS and DOB NOW pages so you can check any row at its source.
DOB publishes to NYC Open Data on a daily cycle; individual datasets can lag it.
OATH / Environmental Control Board — ECB
ECB violations, hearing status, findings and penalties owed.
Refreshed daily through NYC Open Data.
NYC Housing Preservation & Development — HPD
Housing-maintenance-code violations and complaints, building registrations and the head officers and managing agents named on them, litigation, charges, vacate orders and the Alternative Enforcement Program. HPD registration is what turns a shell company on a deed into a named human being — see how to look up your NYC landlord.
Most HPD datasets update daily; registrations update as owners file them.
NYC Department of Finance — DOF and ACRIS
Assessed, market and land value, exemptions, tax liens and charges — and every recorded deed, mortgage, party and legal document through ACRIS, the city's register of property documents going back to 1966.
Assessments follow the annual tax-roll calendar. ACRIS documents appear once recorded.
NYC Department of City Planning — PLUTO, footprints and NTAs
Lot and zoning facts: floor area, FAR, land use, overlays, year built, units, owner of record, plus the city building-footprints file. GeoSearch turns a typed address into a Borough-Block-Lot number and a Building Identification Number. DCP's 2020 census-tract to Neighborhood Tabulation Area equivalency table is what puts a building in a named neighborhood.
PLUTO is republished a few times a year; footprints and GeoSearch update continuously.
NYC Landmarks Preservation Commission — LPC
Individual landmarks, historic districts and designation dates.
Updated when the Commission designates.
311, DEP and DOHMH
311 service requests logged against the building, and boiler, cooling-tower and water-system registrations and inspections.
311 is near real time; agency inspection files update daily to weekly.
NYC energy benchmarking — Local Law 84 and Local Law 97
Energy and water use, ENERGY STAR score, greenhouse-gas intensity and the emissions picture — as filed by the building's own owner, not measured by us.
One filing a year, published in arrears. Figures can be a year or two behind.
New York State Open Data — NYSDEC
Petroleum Bulk Storage: registered fuel-oil tanks at the address. NYSDEC redacts some tank detail, so a thin result does not prove there are no tanks.
Statewide registry, updated by NYSDEC.
NYS Department of State
Corporation and business-entity lookup, used to open the state's own record for a named owner. This one is a link out — nothing is fetched from it.
Wikidata and Wikipedia
Only the history panel on notable buildings. Community-edited encyclopaedia text, not a city record, and it is labelled as such wherever it appears.
What is not here
No credit data, no court records about individuals, no criminal records, no tenant histories, no purchased marketing data. Nothing about people who are not named in a public filing as responsible for a building. If a record is not published by an agency, it is not on this site.
One absence is worth naming because people ask: violations are not attributed to contractors. New York publishes violations against buildings, and the Environmental Control Board records a respondent name but no licence number — so tying a violation to a specific licensed company would mean matching on a company name, and company names collide. Two separately licensed firms sharing a family name cannot be told apart that way. Methodology explains where else that kind of line is drawn.
