/nyc-property-report — Combined NYC Property Report
Runs all 6 NYC property data lookups and produces a combined report. For individual lookups, use the standalone skills:
/nyc-landmarks— LPC landmark & historic district check/nyc-dob-permits— DOB permit & filing history/nyc-dob-violations— DOB & ECB violations/nyc-acris— ACRIS property transaction records/nyc-hpd— HPD violations, complaints & registration/nyc-bsa— BSA variances & special permits
No API key required — all queries use NYC Open Data (Socrata) with PLUTO for address resolution.
Usage
/nyc-property-report 120 Broadway, Manhattan
/nyc-property-report 1000770001 (BBL)
/nyc-property-report 1001389 (BIN)
Step 1: Parse Input
Accept one of:
- Address + Borough/Zip — "120 Broadway, Manhattan" or "120 Broadway 10271"
- BBL — 10-digit number (boro 1 + block 5 + lot 4)
- BIN — 7-digit Building Identification Number
Borough codes: Manhattan=1/MN, Bronx=2/BX, Brooklyn=3/BK, Queens=4/QN, Staten Island=5/SI
Strip apartment/unit/floor suffixes. Handle hyphenated Queens addresses.
Step 2: Resolve via PLUTO
By BBL:
https://data.cityofnewyork.us/resource/64uk-42ks.json?bbl={BBL}
By address:
https://data.cityofnewyork.us/resource/64uk-42ks.json?$where=upper(address) LIKE '%{STREET}%'&borough='{BORO_CODE}'&$limit=5
Address normalization: Uppercase, strip unit/apt. Borough names to codes: Manhattan=MN, Bronx=BX, Brooklyn=BK, Queens=QN, Staten Island=SI. If multiple results, ask user to pick. If zero, try variations or suggest BBL.
Store: bbl, bin/bldgbin, address, borough, zipcode, cd, bldgclass, zonedist1, yearbuilt, ownername, numfloors, lotarea, bldgarea, unitstotal, histdist, latitude, longitude.
Parse BBL: boro (1 digit), block (5 digits zero-padded), lot (4 digits zero-padded).
Step 3: Query All 6 Domains
Query each domain in sequence. If any query fails, note the error and continue with the next domain.
Read socrata-reference.md (in this skill's directory) for the full API reference with field names and SoQL patterns.
Domain 1: Landmarks
By BIN: https://data.cityofnewyork.us/resource/7mgd-s57w.json?bin_number={BIN}
Fallback by BBL: https://data.cityofnewyork.us/resource/7mgd-s57w.json?bbl={BBL}
Also check PLUTO histdist field — if set, property is in a historic district.
Key fields: lpc_name, lpc_number, date_designated, building_type, style, architect, historic_district_name, status
Domain 2: DOB Permits
IMPORTANT: Legacy datasets use bin__ (double underscore). DOB NOW uses bin.
Legacy permits: https://data.cityofnewyork.us/resource/ipu4-2q9a.json?$where=bin__='{BIN}'&$order=issuance_date DESC&$limit=30
Legacy filings: https://data.cityofnewyork.us/resource/ic3t-wcy2.json?$where=bin__='{BIN}'&$order=latest_action_date DESC&$limit=30
DOB NOW permits: https://data.cityofnewyork.us/resource/rbx6-tga4.json?$where=bin='{BIN}'&$order=approved_date DESC&$limit=30
DOB NOW filings: https://data.cityofnewyork.us/resource/w9ak-ipjd.json?$where=bin='{BIN}'&$order=filing_date DESC&$limit=30
Merge, sort by date DESC, group by job type (NB, A1, A2, A3, DM, Other).
Domain 3: DOB Violations
DOB violations: https://data.cityofnewyork.us/resource/3h2n-5cm9.json?$where=bin='{BIN}'&$order=issue_date DESC&$limit=50
ECB violations: https://data.cityofnewyork.us/resource/6bgk-3dad.json?$where=bin='{BIN}'&$order=violation_date DESC&$limit=50
Active violations: https://data.cityofnewyork.us/resource/sjhj-bc8q.json?$where=bin='{BIN}'
Flag open violations with ⚠. Show ECB penalties.
Domain 4: ACRIS
Requires BBL (not BIN). Uses separate borough/block/lot fields.
Step A — Legals: https://data.cityofnewyork.us/resource/8h5j-fqxa.json?borough={boro}&block={block}&lot={lot}&$order=good_through_date DESC&$limit=20
Step B — Master: https://data.cityofnewyork.us/resource/bnx9-e6tj.json?$where=document_id IN ('{id1}','{id2}',...)&$order=doc_date DESC
Step C — Parties: https://data.cityofnewyork.us/resource/636b-3b5g.json?$where=document_id IN ('{id1}','{id2}',...)
Step D — Doc codes: https://data.cityofnewyork.us/resource/7isb-wh4c.json?$limit=200
Join by document_id. Party type 1=Grantor, 2=Grantee. Group by doc type (Deeds, Mortgages, Other).
Domain 5: HPD
First check bldgclass — HPD only applies to residential (classes starting with A, B, C, D, R, S). If non-residential, skip with note.
Uses boroid (not borough) and separate block/lot fields.
Violations: https://data.cityofnewyork.us/resource/wvxf-dwi5.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'&$order=inspectiondate DESC&$limit=50
Open violations: https://data.cityofnewyork.us/resource/csn4-vhvf.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'
Complaints: https://data.cityofnewyork.us/resource/ygpa-z7cr.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'&$order=receiveddate DESC&$limit=30
Registrations: https://data.cityofnewyork.us/resource/tesw-yqqr.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'
Flag Class C violations with ⚠ (immediately hazardous).
Domain 6: BSA
By BBL: https://data.cityofnewyork.us/resource/yvxd-uipr.json?$where=bbl='{BBL}'&$order=calendar_date DESC
Address fallback: https://data.cityofnewyork.us/resource/yvxd-uipr.json?$where=upper(premises_address) LIKE '%{STREET}%' AND borough='{BOROUGH}'&$order=calendar_date DESC
Step 4: Write Report
Write to working directory as property-{address-slug}.md.
