How do you find out who owns a building in NYC?
Look up the address in city records: the PLUTO lot record names the owner of record, and ACRIS holds the deeds and mortgages with their parties. This tool reads both, adds Department of Buildings violations and permits, and screens the owner entities.
Fill in the prompt
Edit the details in brackets with one New York City address, then pick the AI assistant to run it in.
Firecrawl Alexandria runs the lookups
Your assistant calls 7 tools in order, from NYC Open Data property records (ACRIS, PLUTO, DOB) and OpenSanctions, and cites the record behind every figure.
Get the answer
You get the owner of record, last buyer and price, current lender, open violations and penalties, stalled permits and a screen of each owner entity. Anything a source couldn't find is marked, not guessed.

Frequently asked questions
- Which records does it read?
- New York City open data: the PLUTO lot record, ACRIS deeds and mortgages, and Department of Buildings violations and permits.
- Can it find the person behind an LLC?
- It shows the LLC on the deed and the parties named in recorded documents, and screens those names against sanctions lists. A name match isn't proof of identity, and the profile says so.
- Is this tool free?
- Yes. The prompt, the steps and the instructions are free to use. When your assistant runs the tool through Firecrawl Alexandria, each data call bills its listed price in credits, and every data source shows that price before it's called.
- Which AI assistants can run it?
- Any assistant connected to Firecrawl with an API key, including ChatGPT, Claude, Claude Code, Codex and Cursor. Pick one in the prompt box and your request opens there with a link to this tool.
- Do I need to sign up?
- You need a Firecrawl account, with your assistant connected through its API key. Firecrawl Alexandria doesn't run in keyless mode. If your assistant isn't connected yet, the prompt tells it how to set that up. Some data providers ask an admin on your Firecrawl team to accept their terms before the first call.
