Did you know that Chicago’s new Additional Dwelling Unit ordinances allow people to convert attics, basements, and backyards into livable spaces for their loved ones?

What are ADUs?

As small houses or apartments that exist on the same property lot as a single-family residence, Additional Dwelling Units — or ADUs — play a major role in keeping your loved ones close and allowing them to age in place. This home type is re-emerging as an affordable and flexible housing option that meets the needs of older adults and young families alike.
