Cook County Property Records Scraper

Cook County Property Records Scraper

Scrape Cook County property records by PIN or tax year, up to a million per run. Each record returns assessed value, tax details, and parcel attributes in a flat, structured row. Export to CSV, JSON, Excel, or XML.

Cook County's public property portal requires manual lookups one PIN at a time, making bulk analysis slow and tedious. This Actor reads the public tax and assessment records directly, filtered by property index number or tax year, and returns every match in a consistent schema. No browser automation or complex setup needed.

Troubleshooting

Why am I getting no results?

Check that your PIN is exactly 14 digits with no dashes or spaces, and that the tax year you entered is available on the public portal. Try a known-good PIN from a recent tax bill to verify the connection.

The run finished but my dataset is empty.

Your filters may be too restrictive. Remove the tax year filter or widen your PIN list. Also confirm that maxItems is set high enough to capture records after filtering.

I got fewer records than my maxItems setting.

The Actor stops when it runs out of matching records. If you filtered by a specific tax year and PIN list, only those parcels that exist in that year will be returned.

Some fields are blank in my output.

The public record may not have that data for every parcel. Missing fields are normal and reflect what the County has published for that specific PIN and tax year.

The run is taking a long time.

Large maxItems values and broad filters will take longer. Reduce maxItems or narrow your PIN list to speed up the run. The Actor respects the public portal's response time.

FAQ

Question	Answer
What is a PIN in Cook County?	A Property Index Number is a 14-digit identifier assigned to every parcel of land in Cook County. You can find it on tax bills, assessment notices, or the County's online portal.
Can I scrape records without a PIN?	Yes. If you leave the PIN field empty and set a tax year, the Actor will collect records for that year. The number of records depends on the maxItems limit you set.
How many records can I get in one run?	You can set maxItems up to 1,000,000. The actual number returned depends on the filters you apply and the data available on the public portal.
Does this include the property's sale history?	The Actor returns the fields available on the public tax and assessment record. Sale history is not part of the standard tax record but may appear if the source includes it.
Which tax years are available?	The public portal typically holds several recent tax years. Enter a four-digit year like '2023' to filter. If a year is not yet posted, the run will return no results for that filter.
Can I get the property's square footage or bedroom count?	The Actor returns whatever characteristics the public record provides. Building square footage, bedroom count, and other attributes are included when the source publishes them.
Do I need a Cook County account or API key?	No. This Actor reads the public-facing records that anyone can view. No login, no API key, and no registration with the County is required.
Is this legal to scrape?	The Actor accesses publicly available government records. You are responsible for complying with the County's terms of use and any applicable laws regarding data use and redistribution.
What output formats do you support?	Your dataset can be exported as CSV, JSON, Excel, or XML from the Apify platform.
Can I schedule this to run every month?	Yes. Use Apify's scheduler to run the Actor on a recurring basis, for example monthly after tax bills are posted, to keep your dataset current.
