This ordinance would repeal and fully replace Section 17-7-0574 of the Chicago Municipal Code, which lists the single-family (RS) zoning areas where Additional Dwelling Units (ADUs), such as conversion units and coach houses, are allowed. The new section defines these areas and their limits in a table, but the table itself is not included in the document provided. The ordinance would take effect on April 1, 2026.
