Chicago City Council Raises Doubts About Legalizing ‘Granny Flats’ or Accessory Dwelling Units

CHICAGO (WLS) — Chicago lawmakers are divided on legalizing the construction of Accessory Dwelling Units, or ADUs.

These secondary living spaces are illegal to build in most of Chicago, and political gridlock is keeping it that way.

For over six years, city officials working with three different mayors have been striving to lift the ban on ADUs, which stand for accessory dwelling units. This includes transforming coach houses as well as unused basement or attic areas into livable apartments.

Advocates of legalizing ADUs, which include government officials and policy experts, frequently emphasize that these units are a taxpayer-free solution with minimal risks. They are seen as a way to effectively and modestly alleviate housing shortages, as demonstrated in other cities.

Yet, many members of the Chicago City Council remain doubtful about allowing ADUs, concerned it might reduce their influence over the development decisions within their wards. This skepticism is a key reason why the proposal to legalize these units citywide has been pending for over a year.
