SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The skill determines whether a NYC building is individually landmarked or within a historic district using LPC data, helping architects and planners quickly assess regulatory implications.

Core Features & Use Cases

  • Input flexibility: Accepts an address, BBL, or BIN to resolve status.
  • Data source integration: Cross-checks PLUTO and LPC datasets to provide landmark, designation date, LP number, and district information.
  • Use Case: A designer reviews a site at 120 Broadway and immediately understands whether LPC approvals apply before design decisions.

Quick Start

Provide a NYC building address, BBL, or BIN to fetch its landmark designation and historic district information.

FAQPage Schema
How do I check if a NYC building is in a historic district or individually landmarked?▼

Check NYC landmark status by providing an address, BBL, or BIN to cross-reference PLUTO and LPC datasets, which returns the individual landmark designation, LP number, and historic district information for the property.

Can I look up LPC landmark designation dates using a BIN?▼

Yes, you can look up LPC landmark designation dates using a BIN. The tool resolves the BIN via PLUTO and queries the LPC dataset to return the designation date, style, and district information without requiring an API key.

Do I need an API key to query NYC landmark data for an address?▼

You do not need an API key to query NYC landmark data. The tool resolves addresses directly through PLUTO and LPC datasets to return landmark status and district information in a structured format.

What is the best way to find historic district status for a specific BBL in NYC?▼

Finding historic district status for a specific BBL involves inputting the BBL directly, allowing the tool to cross-check PLUTO and LPC datasets to determine if the property falls within a regulated historic district.

Does address normalization affect how LPC landmark status is resolved?▼

Address normalization is handled internally during the PLUTO resolution process, ensuring varied address formats are standardized correctly before querying the LPC dataset for accurate landmark and historic district results.
