Chicago Commercial and Industrial Real Estate Appraisals



Our philosophy is simple: instead of offering many services, we would rather focus on our core competencies in order to provide the very best solutions for our clients. We focus 100% of our energy, thought and research toward commercial property valuation.


The days of effective one or two-person commercial appraisal shops are coming to a close. They simply lack resources and exposure to enough properties to adequately understand the market.  Our appraisers live all around the metro area to enhance our knowledge of various markets.  We have a vastly deeper bench at virtually every level of our operation.

Most appraisal firms rely exclusively on canned off-the-shelf data sources. Our firm has been well known for years for its customized research and studies of various aspects of the Chicago real estate market.


CCAG is owned by Gary Peterson, MAI, MBA who also manages the company with Michael Halliburton, MAI. Together they have over 50 years of commercial appraisal experience. Our State Licensed and Certified appraisers have many decades more of commercial appraisal experience.
formerly known as Peterson Appraisal Group LTD

Our law firm provides legal work for real estate closings for over 30 years… What distinguishes Chicago Commercial Appraisal Group from other appraisers is the level of thoroughness and details.

A. Raila, Senior Tax Analyst

Gary is a hands-on professional always willing to pick up the phone and work with you... His appraisal firm produces one of the best real estate forecasting reports in the state. I highly recommend his work and his opinion is highly recognized by governmental agencies.

J. Norris, Property Tax Attorney

As an attorney, we deal with many appraisal reports used in tax appraisals. Gary's work has proven successful for our clients and I do not hesitate recommending him for tax assessment appeal appraisals.

C. Noone, property owner

I needed an appraisal for settling an estate. Mr. Peterson was very professional, punctual and helpful with the process. I received my report ina timely manner. I would certainly recommend this company, as well as use their services in the future.

Gary is one of the top commercial appraisers in Chicago. Every time I have a client in need of a commercial appraiser I refer all work to him without hesitation.
