Nyc Dob Permits

/as:nyc-dob-permits — DOB Permit & Filing History

Look up all DOB permits and job filings for any NYC building across both Legacy BIS and DOB NOW systems. No API key required.

Usage

/as:nyc-dob-permits 120 Broadway, Manhattan
/as:nyc-dob-permits 1000770001          (BBL)
/as:nyc-dob-permits 1001389             (BIN)

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

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), resolve via PLUTO, and resolve BIN via Building Footprints — BIN is required for every query in Step 3.

Step 3: Query DOB Permits & Filings

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

Query all 4 datasets using BIN. IMPORTANT: Legacy datasets use bin__ (double underscore). DOB NOW datasets use bin.

Legacy Permit Issuance

https://data.cityofnewyork.us/resource/ipu4-2q9a.json?$where=bin__='{BIN}'&$order=issuance_date DESC&$limit=30

Key fields: permit_si_no, job__, job_type, issuance_date, expiration_date, permittee_s_first_name, permittee_s_last_name, owner_s_first_name, owner_s_last_name

Legacy Job Filings

https://data.cityofnewyork.us/resource/ic3t-wcy2.json?$where=bin__='{BIN}'&$order=latest_action_date DESC&$limit=30

Key fields: job__, doc__, job_type, job_status, latest_action_date, applicant_s_first_name, applicant_s_last_name

DOB NOW Approved Permits

https://data.cityofnewyork.us/resource/rbx6-tga4.json?$where=bin='{BIN}'&$order=approved_date DESC&$limit=30

Key fields: job_filing_number, work_permit, permit_status, work_type, approved_date, issued_date, expired_date (this dataset has NO filing_date or job_type — use approved_date / work_type)

DOB NOW Job Filings

https://data.cityofnewyork.us/resource/w9ak-ipjd.json?$where=bin='{BIN}'&$order=filing_date DESC&$limit=30

Key fields: job_filing_number, filing_status, filing_date, job_type

Step 4: Print Results

Merge all results, sort by date descending. Group by job type:

• NB = New Building
• A1 = Alteration Type 1 (major — changes use/egress/occupancy)
• A2 = Alteration Type 2 (multiple work types)
• A3 = Alteration Type 3 (minor, one work type)
• DM = Demolition
• Other = Everything else

## DOB Permits & Filings — {Address}

**Total found:** {count} ({x} legacy, {y} DOB NOW)

### New Building (NB)
| Date | Job # | Permit # | Status | Applicant |
|------|-------|----------|--------|-----------|
| ... | ... | ... | ... | ... |

### Alteration Type 1 (A1)
| Date | Job # | Permit # | Work Type | Status | Applicant |
|------|-------|----------|-----------|--------|-----------|

### Alteration Type 2-3 (A2/A3)
{table}

### Demolition (DM)
{table if any}

### Other
{table if any}

**Note:** Pre-BIS records (before ~1989) are not digitized. If this building predates 1989 and few records appear, earlier permits exist only on paper.

If no results from any dataset: "No DOB permits or filings found for this property."

Conventions

• All dates: YYYY-MM-DD
• 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
• Check PLUTO yearbuilt — if before 1989, add the pre-BIS note

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.
