Measure To Allow New Coach Houses, Basement Units Citywide Advances With Restrictions

The Chicago City Council's zoning committee advanced a proposal to permit additional dwelling units (ADUs) citywide, a move aimed at alleviating the local affordable housing shortage. Proposed by Ald. Bennett Lawson, the ordinance allows for the construction of units such as coach houses and basement apartments without the need for zoning changes. The committee passed the measure 13-7, though it faced criticism from members like Ald. Marty Quinn, who fears it will undermine single-family neighborhood integrity.

To appease dissenters, the legislation includes limits on the number of ADUs allowed per block based on zoning classifications. Mayor Brandon Johnson advocates for the ordinance as part of his Cut The Tape initiative, which seeks to streamline development in Chicago. Under the new rules, homeowners must reside in the property where they intend to build an ADU, reinforcing neighborhood character. The full City Council is set to vote on the proposal Wednesday, although opponents may attempt to delay the decision. The measure builds on a pilot program initiated in 2021 that allowed ADU construction in select areas.
