Non-Residential Assessment Search Instructions Page

Welcome to Cook County Assessor James M. Houlihan’s Non-Residential Assessment Search Page.

Using this search function, you may view property information, including property location (city, township and address), class, tax code, and age information, as well as prior and current assessment values. This information is similar to what is found on your "Notice of Proposed Assessed Valuation," mailed by the Assessor’s Office. If you find that your property’s information has been listed incorrectly, or you disagree with your assessed value, you may consider filing a non-residential appeal with the Cook County Assessor’s Office.

If you wish to appeal your assessment, some information that you may wish to provide with a non-residential appeal could include, but need not be limited to the following: recent purchase price, income or rental data, appraisal value, or vacancy/occupancy data. Please click here to see guidelines for filing non-residential appeals and corresponding forms.

The most current assessment information will only be available for properties in triennial reassessment townships that have been mailed their "Notice of Proposed Assessed Valuation." For a listing of available townships and mailing dates click here.

Please read the following instructions for information on how to best conduct an assessment search for non-residential property.

Search Instructions

There are two main search functions available to you in performing an assessment search for non-residential property in Cook County. You may search by Property Index Number (PIN) or by address. If you already know your PIN, use the "Search by Property Index Number" function. If you do not know your PIN, you may use the "Search by Address" function. The third, "Search by Neighborhood" function, is primarily used for residential properties, but may be used as a geographic location tool for non-residential properties. It is important to note that there are often multiple addresses for certain non-residential properties.

Once you have finished reading these instructions, you may begin your non-residential search by clicking on one of the highlighted, "Click Here to Begin a Search" button at the top and bottom of this page. This will bring you to the Internet browser, or you may click the highlighted "Help on searching" on the bottom of the Property Search page. You may refer back to these instructions at anytime by clicking the "Back" button at the top of your Internet browser.

Search by Property Index Number

From the "Assessment Search" page you may conduct a search by entering your 14 digit Property Index Number (PIN) in the corresponding boxes in the "Search by Property Index Number" function. Your PIN can be found on your "Notice of Proposed Assessed Valuation," or on your tax bill. The first 2 digits should be entered into the first box, the second 2 in the second box, 3 digits in each of the third and fourth boxes, and the remaining 4 digits in the last box. Once you have entered your PIN, click once on the "Search by PIN" button. This will bring up a page with your desired PIN, corresponding address, class code, neighborhood, assessed value, and city. Simply click once on the highlighted PIN for more information on your desired property.

Search by Address

If you wish to obtain information on a specific non-residential property but you do not know the PIN, simply enter the address in the "Search by Address" function. It should be noted that due to the transitory nature of addresses, our address file might contain errors or omissions. If you experience difficulties, please call the Cook County Assessor’s Office Taxpayer Information Department at 312-443-7550. When entering the street name of your desired property, to aid in your search, please do not enter the street suffix, such as St., Dr., Ave., etc. You will then need to enter the city name in the box on the third line of the section. Please note that you do not need to select a class to conduct a search.

Once the required fields of information are entered, click once on the "Search by Address" button to submit your search. This will bring up a page with your desired PIN, corresponding address, class code, neighborhood, assessed value, and city. Simply left click once on the highlighted PIN for more information on your property.

Search Help: If you are having difficulty finding a property or wish to expand your search, try entering less information. For instance, in the "Search by Address" function leave the direction box blank, or only enter the first few letters of the street or city. In the "Search by PIN" function, if you enter only the first seven numbers of your PIN (i.e…if your index number is 01-01-123-456-0000, and you only insert 01-01-123) this will expand your search to include all the properties that share those seven digits in ascending PIN order. This will widen the parameters for the database and improve the possibility that a record is found.

Please Note: This is non-residential property. Unlike residential property, it may be misleading to compare properties based solely on the information contained on this site. Many factors are considered when assessing non-residential properties. These factors include, but are not limited to, recent purchase price, zoning consideration, income or rental data, appraisal value, and vacancy/occupancy data.
