Chicago Council Reaches Compromise to Expand 'Granny Flats' Citywide

Chicago aldermen have reached a compromise to legalize and expand accessory dwelling units (ADUs), including coach houses and granny flats, across the city, aiming to address the housing shortage exacerbated by soaring rents. The new ordinance permits ADUs in multi-unit and commercial zones citywide without special permission but requires aldermanic approval for single-family neighborhoods, preserving local control to maintain neighborhood character. Ald. Marty Quinn, representing a single-family dominated ward, successfully pushed for these restrictions and secured union support by mandating that contractors involved in new coach house construction participate in approved labor apprenticeship programs. The compromise, supported by Ald. Bennett Lawson and Mayor Brandon Johnson, balances the need for increased housing supply with local input and labor standards. It is set for a City Council vote and expected to pass, marking a significant step toward expanding affordable housing while addressing concerns about overpopulation and infrastructure strain in certain neighborhoods. The ordinance also includes limits on the number of ADUs per block annually and requires owner occupancy for detached houses adding ADUs.
