Chicago could add 8,000 granny flats by following Los Angeles’ leadLegalizing additional dwelling units citywide would bring more housing choices, lower costs and help Chicagoans stay in the neighborhoods they love. Los Angeles, which has a similar number of single-family neighborhoods as Chicago, fully legalized the units in 2016. Since then, about 5% of single-family homes there have gotten a permit for one – adding about 27,000 new residences in total. But nearly five years later, less than 300 permits have been issued, largely because of the extensive restrictions Chicago imposes. Additional dwelling units are an ideal solution for cities such as Los Angeles and Chicago with many single-family homes.
