Public record
FAA obstruction case lookup
Every structure tall enough to matter near an American airport is filed with the FAA, and every filing is public. The FAA's own portal makes you fill in a form and gives you nothing you can link to. This is the same record, one page per case, with the things the portal leaves out: what is nearby, what the organisation files elsewhere, what the determination actually means, and when it expires.

About this data
Sourced from the FAA's Obstruction Evaluation / Airport Airspace Analysis public archive, 2,298,277 case records in total. These pages are a readable mirror, not the official record — the FAA's portal is authoritative. Cases filed by private individuals are excluded entirely. Aggregate analysis of the whole archive is in our filings data report.
