The Chicago History Museum holds many resources for researching the history of Chicago building, whether you want to know something about your condo in a former shoe factory, a bungalow on the west side, or a downtown commercial building. A visit to the Abakanowicz Research Center will provide many possibilities for research, and staff is always available at the Reference Desk to help you. Some resources can be accessed remotely.
If you are not able to come in yourself, you may want to hire a house history researcher from our freelance researcher list.
