The permit record, on the listing page.

Listings tell you the house has a finished basement. They do not tell you whether anyone ever pulled a permit for it. Our free extension reads the address on any Zillow or Redfin listing and shows you what the city has on file.

§ 01 · How It Works

Install it once, then forget it is there until it matters

01

Add it to Chrome

One click from the Chrome Web Store. No account, no card, nothing to configure. It works in Chrome, Edge, Brave, Arc, Opera and Vivaldi.

02

Browse listings as normal

Zillow and Redfin, on any address inside our coverage. The extension stays completely dormant on every other site you visit.

03

Click the marker

A small marker appears in the corner with the permit count and open-permit flags. Click it for the summary, or pull the full report.

§ 02 · What You See

Enough to know whether to worry

The marker answers one question for free: is there anything here worth looking into? The report answers the rest.

What it will not do

Show a zero it cannot stand behind

Outside our 34 cities the marker simply does not appear. An empty result on an uncovered address would read as a clean history, and that is worse than silence.

Read anything but the address

It pulls the listing address and asks our database about it. It does not touch your saved searches, your account, or any other page you visit.

Work in Safari or Firefox

Not yet, and not on phones. Chrome, Edge, Brave, Arc, Opera and Vivaldi all install from the same store link.

Replace a permit search at the city

We publish what the city publishes. Records lag, and some departments never mark a permit closed. Treat an open permit as a question to ask, not a verdict.

What we collect and why is set out in full in our privacy policy.
