Where can you find architect's plans of old homes in Old Irving Park neighborhood?
A good place to start is at the UIC library. They have quite a collection of original building permits. From there you can research the architect of record (if there was one). Many homes in Old Irving were built by the owners with limited or no plans. My next door neighbor was born in her house, which was built by her grandfather. She has photos of my house from the early 20th century. Ask around the community or check at the Historical Society located at Irving & Keeler.
