Public-record evidence Five reports on sale · nine free tools

Public records, checked before your deadline.

CivicDelta gathers the official government records for one property, nursing home or surgeon into a single dated file: Cook County property tax appeal evidence, Chicago building permit history, nursing home inspection records in any state, and a surgeon’s Medicare procedure volume beside their peers. Every report starts with a free check that tells you whether there is anything worth paying for.

  • Every figure carries its dataset, record ID and capture date.
  • One flat price per report, and you can pay only after coverage is confirmed.
  • “No records found” is reported as an answer, never as clearance.
Three domains

Every report, grouped by what you’re deciding about

Every report uses the same method, the same citation format and the same limits statement, whichever domain it’s in. We open one jurisdiction at a time and sell a report only where our data covers you.

The data foundation

The ten Cook County and Chicago datasets behind the Property reports

Before we load a dataset, we ask the publisher how many records to expect, and a load that doesn’t match is blocked. These are the rows published for the years we keep. The Health & Care and Hiring & Education reports use 15 more national and California datasets, listed on the Sources page.

Our standard

What you can hold us to, in every domain

  1. Coverage before payment

    We confirm your address or entity is covered before you can pay.

  2. Every figure cited

    Publisher, dataset, record ID and capture date sit beside every number.

  3. Absence is not clearance

    “No records found” never means “no problem.” Every report says so.

  4. Records, not accusations

    No scores or grades about named people or businesses. Dated records only.

  5. One price, stated up front

    A single number per report. A clean result is declared a valid outcome before you buy.

  6. The free source, linked

    Each report links the official lookup it builds on, so you can check it yourself.
