/as:nyc-dob-permits — DOB Permit & Filing History
Harness note: use /as:<skill> on Claude Code and $<skill> on Codex. Resolve <skill-root> as the directory containing this loaded SKILL.md and <plugin-root> as the plugin root that contains skills/, and use equivalent native tools when host tool names differ.
Look up all DOB permits and job filings for any NYC building across both Legacy BIS and DOB NOW systems. No API key required.
Usage
/as:nyc-dob-permits 120 Broadway, Manhattan
/as:nyc-dob-permits 1000770001 (BBL)
/as:nyc-dob-permits 1001389 (BIN)
Steps 1–2: Parse Input & Resolve BBL/BIN
Read ../nyc-property-report/pluto-resolution.md (shared by all 7 NYC due-diligence skills) and follow it: parse the input (address, BBL, or BIN), resolve via PLUTO, and resolve BIN via Building Footprints — BIN is required for every query in Step 3.
Step 3: Query DOB Permits & Filings
Dataset IDs and field names are canonical in ../nyc-property-report/socrata-reference.md — on any disagreement, the reference wins.
Query all 4 datasets using BIN. IMPORTANT: Legacy datasets use bin__ (double underscore). DOB NOW datasets use bin.
Legacy Permit Issuance
https://data.cityofnewyork.us/resource/ipu4-2q9a.json?$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.
