/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.

Step 5: Summary

After writing the file, print a brief inline summary:

Property report written: property-120-broadway.md

Key findings:
- Landmark: Not designated
- DOB Permits: 47 found (3 active filings)
- Open Violations: 2 (1 ECB with $25,000 penalty)
- Owner: {name} (per ACRIS deed YYYY-MM-DD)
- HPD: N/A (commercial building)
- BSA: 1 approved variance (2004)

Run /zoning-analysis-nyc for zoning envelope data.

Conventions

• All dates: YYYY-MM-DD
• Dollar amounts: comma-separated
• Open/active items flagged with ⚠
• If a domain returns no results, say so explicitly (don't omit the section)
• If a domain query fails (network error, rate limit), note the error and continue
• Always include the "Data currency varies" caveat

Edge Cases

• Rate limited (HTTP 429): Wait 5 seconds, retry once. If still 429, note error and suggest setting NYC_SOCRATA_TOKEN.
• ACRIS with many documents: Limit to 20 most recent. Note if truncated.
• Condo lots: ACRIS keys on individual unit lots. Note to search parent condo lot too.
• Pre-1989 buildings: Pre-BIS DOB records not digitized. Note if few permits for old building.
• Multiple BINs: If PLUTO shows numbldgs > 1, note that lot has multiple buildings.
• No results from any API: State clearly per section. Don't fail the whole report.
