# /nyc-landmarks — LPC Landmark & Historic District Check Check if a NYC building is individually landmarked or within a historic district using the LPC Individual Landmark & Historic District Building Database. No API key required. ## Usage ``` /nyc-landmarks 120 Broadway, Manhattan /nyc-landmarks 1000770001 (BBL) /nyc-landmarks 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 (ST vs STREET, AVE vs AVENUE) or suggest providing a BBL. Store from PLUTO: `bbl`, `bin` (or `bldgbin`), `address`, `borough`, `bldgclass`, `zonedist1`, `yearbuilt`, `ownername`, `numfloors`, `lotarea`, `latitude`, `longitude`, `histdist`. Parse BBL into: boro (1 digit), block (5 digits zero-padded), lot (4 digits zero-padded). ## Step 3: Query LPC Database Use the Individual Landmarks dataset (`buis-pvji`). Query by BBL first: ``` https://data.cityofnewyork.us/resource/buis-pvji.json?bbl={BBL} ``` If no results, fallback by block + lot: ``` https://data.cityofnewyork.us/resource/buis-pvji.json?$where=block='{BLOCK}' AND lot='{LOT}' AND borough='{BOROUGH}' ``` Key fields: `lpc_name`, `lpc_lpnumb`, `desdate`, `landmarkty`, `lpc_sitede`, `lpc_sitest`, `lpc_altern`, `address`, `url_report` Also check PLUTO's `histdist` field from Step 2 — if it has a value, the property is in a historic district even if not individually listed in the LPC dataset. ## Step 4: Print Results ```markdown ## Landmark Status — {Address} **Status: LANDMARKED / IN HISTORIC DISTRICT / NOT DESIGNATED** | Field | Value | |-------|-------| | LP Number | {lpc_lpnumb} | | Name | {lpc_name} | | Designation Date | {desdate} | | Type | {landmarkty} | | Site Description | {lpc_sitede} | | Site Style | {lpc_sitest} | | Also Known As | {lpc_altern} | | LPC Report | {url_report} | | Historic District | {histdist from PLUTO} | **Implications:** Exterior alterations require LPC Certificate of Appropriateness before DOB permit. Source: [LPC Individual Landmarks](https://data.cityofnewyork.us/Housing-Development/Individual-Landmarks/buis-pvji) ``` If not landmarked and not in a historic district: "No landmark designation 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
