# /nyc-dob-violations — DOB & ECB Violations
Look up DOB violations and ECB (Environmental Control Board) violations for any NYC building. Flags open violations prominently. No API key required.
## Usage
```
/nyc-dob-violations 120 Broadway, Manhattan
/nyc-dob-violations 1000770001 (BBL)
/nyc-dob-violations 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
## Step 2: Resolve via PLUTO
Query PLUTO to get BBL, BIN, and building metadata. No API key needed.
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 suffixes. Borough names to codes: Manhattan=MN, Bronx=BX, Brooklyn=BK, Queens=QN, Staten Island=SI. If multiple results, ask the user to pick. If zero, try variations or suggest providing a BBL.
Store from PLUTO: `bbl`, `bin` (or `bldgbin`), `address`, `borough`, `bldgclass`, `zonedist1`, `yearbuilt`, `ownername`, `numfloors`, `lotarea`, `latitude`, `longitude`.
Parse BBL into: boro (1 digit), block (5 digits zero-padded), lot (4 digits zero-padded).
## Step 3: Query Violations
Query 3 datasets using BIN:
### DOB Violations
```
https://data.cityofnewyork.us/resource/3h2n-5cm9.json?$where=bin='{BIN}'&$order=issue_date DESC&$limit=50
```
Key fields: `isn_dob_bis_viol`, `violation_type`, `issue_date`, `violation_category`, `disposition_date`, `disposition_comments`
### ECB Violations
```
https://data.cityofnewyork.us/resource/6bgk-3dad.json?$where=bin='{BIN}'&$order=issue_date DESC&$limit=50
```
Key fields: `isn_dob_bis_extract`, `ecb_violation_number`, `violation_type`, `issue_date`, `penality_imposed`, `amount_paid`, `balance_due`, `hearing_status`, `ecb_violation_status`, `severity`
### Active/Open Violations
```
https://data.cityofnewyork.us/resource/sjhj-bc8q.json?$where=bin='{BIN}'
```
Returns only currently open violations (pre-filtered subset of DOB violations).
## Step 4: Print Results
Open violations go first, flagged with ⚠.
```markdown
## DOB & ECB Violations — {Address}
### ⚠ Open Violations: {count}
| Violation # | Type | Date | Description | Disposition |
|-------------|------|------|-------------|-------------|
| ... | ... | YYYY-MM-DD | ... | ... |
### All DOB Violations ({count} total)
| Violation # | Type | Issue Date | Category | Disposition Date | Comments |
|-------------|------|------------|----------|------------------|----------|
| ... | ... | ... | ... | ... | ... |
### ECB Violations ({count} total)
| ECB # | Date | Violation Type | Severity | Penalty Imposed | Paid | Balance Due | Status |
|-------|------|----------------|----------|-----------------|------|-------------|--------|
| {ecb_violation_number} | {issue_date} | {violation_type} | {severity} | ${penality_imposed} | ${amount_paid} | ${balance_due} | {hearing_status} |
**Total penalties assessed:** ${amount}
**Total balance due:** ${amount}

If no violations found: "No DOB or ECB violations found for this property."
