What a record page shows

The county record, the permits, and what comes next.

The county record

Year built, size, bedrooms and bathrooms, home type and the Property Index Number (PIN), straight from the Cook County Assessor's records.

Permit history

Building permits matched to the home, from the City of Chicago and, for the suburbs, the permits the Cook County Assessor records. A permit we can't tie to exactly one home is left off rather than guessed.

What's coming up

Which systems are nearing the years they typically need replacing, from the home's age and permits. Mark what is already done and the timeline updates. Send your list to a local pro for a quote.
