/nyc-hpd — HPD Violations, Complaints & Registration

Look up HPD (Housing Preservation & Development) violations, complaints, and building registration for NYC residential buildings. Only applies to residential building classes. No API key required.

Usage

/nyc-hpd 1055 Bergen Street, Brooklyn
/nyc-hpd 3012120065          (BBL)
/nyc-hpd 3030348             (BIN)

Steps 1–2: Parse Input & Resolve BBL

Read ../nyc-property-report/pluto-resolution.md (shared by all 7 NYC due-diligence skills) and follow it: parse the input (address, BBL, or BIN — e.g. "1055 Bergen Street, Brooklyn") and resolve via PLUTO. HPD queries key on boro/block/lot, so BIN resolution is only needed when the user's input was a BIN.

Check Building Class

Before querying HPD, check bldgclass from PLUTO. HPD only applies to residential buildings — classes starting with A, B, C, D, R, or S.

If the building class does NOT start with one of those letters, print:

"Building class {X} — HPD records not applicable (non-residential)."

And stop. Do not query HPD APIs.

Step 3: Query HPD Datasets

Dataset IDs and field names are canonical in ../nyc-property-report/socrata-reference.md — on any disagreement, the reference wins.

IMPORTANT: HPD violations/registrations use boroid (not borough). And block/lot are separate fields — not a combined BBL.

HPD Violations

https://data.cityofnewyork.us/resource/wvxf-dwi5.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'&$order=inspectiondate DESC&$limit=50

Key fields: violationid, class (violation class — NOT violationclass), inspectiondate, approveddate, originalcertifybydate, novdescription, currentstatus

Open HPD Violations

https://data.cityofnewyork.us/resource/csn4-vhvf.json?$where=boroid='{boro}' AND block='{block}' AND lot='{lot}'

Pre-filtered to currently open violations.

Complaints

Note: The complaints dataset uses borough (text like "MANHATTAN", "BRONX", "BROOKLYN", "QUEENS", "STATEN ISLAND") — NOT boroid. Map boro codes: 1→MANHATTAN, 2→BRONX, 3→BROOKLYN, 4→QUEENS, 5→STATEN ISLAND.

https://data.cityofnewyork.us/resource/ygpa-z7cr.json?$where=borough='{BOROUGH_NAME}' AND block='{block}' AND lot='{lot}'&$order=received_date DESC&$limit=30

Key fields: complaint_id, received_date, complaint_status, complaint_status_date, major_category, minor_category, problem_status

Registrations

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

Key fields: registrationid, buildingid, bin, registrationenddate, lastregistrationdate

Note: The registrations dataset has NO owner-name fields. Get owner/agent names from Registration Contacts (feu5-w2e2), keyed by registrationid:

https://data.cityofnewyork.us/resource/feu5-w2e2.json?$where=registrationid='{registrationid}'

Key fields: type (CorporateOwner / Agent / HeadOfficer / IndividualOwner), firstname, lastname, corporationname

Step 4: Print Results

## HPD — {Address}

### Registration
| Field | Value |
|-------|-------|
| Registration ID | ... |
| Owner | {corporationname or firstname lastname, from registration contacts} |
| Registration Expiry | YYYY-MM-DD |

### ⚠ Open Violations: {count}
**Class C (Immediately Hazardous):** {count} ⚠
**Class B (Hazardous):** {count}
**Class A (Non-Hazardous):** {count}

| Violation ID | Class | Inspection Date | Description | Certify By |
|-------------|-------|-----------------|-------------|------------|
| ... | C ⚠ | YYYY-MM-DD | ... | YYYY-MM-DD |

### All Violations ({count} total, showing 50 most recent)
| Violation ID | Class | Inspection Date | Approved Date | Description |
|-------------|-------|-----------------|---------------|-------------|

### Recent Complaints ({count} total, showing 30 most recent)
| Complaint ID | Received | Category | Status | Status Date |
|-------------|----------|--------|-------------|

If no results: "No HPD violations, complaints, or registrations found for this property."

Conventions

• All dates: YYYY-MM-DD
• Class C violations always flagged with ⚠ (immediately hazardous — must be corrected within 24 hours)
• Open/active items listed first
• If Socrata returns empty array: "No results found"
• If HTTP error: note it and suggest checking the address
• If the user requests, write results to a file

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.
