Put a rent-stabilization checker on your site

If you run a tenant organisation, a legal-aid site, or a housing desk, you probably answer “is this building rent-stabilized?” over and over. This does it for you, on your own page. It’s free, there’s no API key, and it doesn’t track anyone.

Add it in one line

Paste this wherever you want the checker to appear:

<div id="findacrib-check"></div>
<script src="https://findacrib.com/embed/widget.js" async></script>

Need more than one on a page, or a different container? Put data-findacrib-check on any element instead of using the id.

What it checks against

47,000+ NYC buildings registered rent-stabilized with NY State DHCR (2024 building files), across all five boroughs.
Unit count, year built, neighborhood, and open HPD violations for each match.
Links through to the full record on the map — owner, managing agent, and violation history.

It states its own limits, and so should you. Registration is at the building level. It does not guarantee that a specific apartment is stabilized — individual units can be deregulated, and only the DHCR rent history for that unit settles it. The widget says this on every result, because a tool that implied otherwise would be worse than no tool.

The fine print, briefly

No key, no signup. The lookup endpoint is keyless and rate limited per visitor IP.
No tracking. No cookies, no analytics, no pixel. We don’t see who your readers are.
No dependencies. Plain JavaScript, ~6 KB, renders in a Shadow DOM so your CSS can’t break it and its CSS can’t leak into your page.
Attribution. The widget links back to Find A Crib. That link is the only thing we ask for.
Bulk data. If you need the whole dataset rather than per-address lookups, that’s the Developer API.

Using it in a story?

If you’re a reporter working on rent regulation, we’re happy to pull custom cuts of the data — by neighborhood, by owner portfolio, by violation history — and we won’t ask for anything in return beyond a source credit. Email api@findacrib.com.
