MLS data is a rearview mirror. Permit data is a windshield.
Every listing presentation, every CMA, every investment analysis starts with the same data: recent sales, price per square foot, days on market. The problem? By the time a sale closes and shows up in the MLS, the market has already moved.
Institutional investors — Blackstone, Invitation Homes, the hedge funds — don't wait for comps. They track building permits, construction activity, and code violations to predict where values are heading. They see renovation clusters forming, new construction pipelines filling up, and neighborhoods transforming months before retail agents notice.
That data has always been public. It sits in the NYC Department of Buildings databases — DOB NOW, BIS, and ECB. But it's scattered across three different systems with different formats and update schedules. Searching manually is tedious enough that almost nobody does it.
PermitBeam pulls from all three sources, filters by your ZIP codes, and delivers a clean weekly digest. You get the same forward-looking intelligence that institutional players use — without the institutional budget.
