Nyc Property Report

/as: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:

• /as:nyc-landmarks — LPC landmark & historic district check
• /as:nyc-dob-permits — DOB permit & filing history
• /as:nyc-dob-violations — DOB & ECB violations
• /as:nyc-acris — ACRIS property transaction records
• /as:nyc-hpd — HPD violations, complaints & registration
• /as:nyc-bsa — BSA variances & special permits

No API key required — all queries use NYC Open Data (Socrata) with PLUTO for address resolution.

Project context

If PROJECT.md exists in the working directory, read it before fetching — prior lookups may already be on file. After completing, offer identity facts (address, BBL, ownership), landmark status, and the open-violations summary to /as:project update for its Identity and Zoning sections, each with a source and date. No PROJECT.md? Skip silently — or mention /as:project init if the user is clearly starting a project.

Usage

/as:nyc-property-report 120 Broadway, Manhattan
/as:nyc-property-report 1000770001          (BBL)
/as:nyc-property-report 1001389             (BIN)

Steps 1–2: Parse Input & Resolve BBL/BIN

Read pluto-resolution.md (in this skill's directory) and follow it: parse the input (address, BBL, or BIN), resolve via PLUTO, and resolve BIN via Building Footprints.

This skill's extras: in addition to the base PLUTO field set, store zipcode, cd, bldgarea, unitstotal, histdist, numbldgs.

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) — it is the single source of truth for every dataset ID and field name below. If a query here ever disagrees with it, the reference wins.

Domain 1: Landmarks

By BBL: https://data.cityofnewyork.us/resource/buis-pvji.json?bbl={BBL}

Fallback by block + lot (NOT zero-padded): https://data.cityofnewyork.us/resource/buis-pvji.json?$where=block='{BLOCK}' AND lot='{LOT}' AND borough='{BOROUGH}'

Also check PLUTO histdist field — if set, property is in a historic district.

Key fields: lpc_name, lpc_lpnumb, desdate, landmarkty, lpc_sitede, lpc_sitest, lpc_altern, address, url_report

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=issue_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=document_date DESC (fields: document_date, document_amt, recorded_datetime)

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 (uses borough as TEXT — "MANHATTAN", "BROOKLYN", … — not boroid): https://data.cityofnewyork.us/resource/ygpa-z7cr.json?$where=borough='{BOROUGH_NAME}' AND block='{block}' AND lot='{lot}'&$order=received_date DESC&$limit=30

Registrations: https://data.cityofnewyork.us/resource/tesw-yqqr.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'

Registration contacts (owner names — registrations dataset has none): https://data.cityofnewyork.us/resource/feu5-w2e2.json?$where=registrationid='{registrationid}'

Flag Class C violations with ⚠ (immediately hazardous).

Domain 6: BSA

By BBL: https://data.cityofnewyork.us/resource/yvxd-uipr.json?$where=bbl='{BBL}'&$order=date DESC

Address fallback: https://data.cityofnewyork.us/resource/yvxd-uipr.json?$where=upper(street_name) LIKE '%{STREET}%' AND borough='{BOROUGH}'&$order=date DESC

Step 4: Write Report

Write to working directory as property-{address-slug}.md.

*Data currency varies by dataset. Verify critical findings with source agencies.*

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 /as: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.

Final Step: Disclaimer + Marker (required)

This skill produces regulatory output. End every report this skill produces — printed in chat or saved to a file — with the canonical disclaimer block from rules/professional-disclaimer.md, followed by one blank line and the machine-readable marker, exactly as shown:

> **Disclaimer:** This is an AI-generated analysis for preliminary planning purposes. All findings must be verified by a licensed professional before use in design, permitting, or regulatory submissions.

<!-- architecture-studio:requires-disclaimer -->

The marker is a single end-of-file sentinel — it appears exactly once, as the last line of the report. The post-write-disclaimer-check hook parses saved .md reports for the marker and blocks the write if the canonical disclaimer block is missing.
