Quinn pushing ‘decoy’ ordinance to block granny flatsAld. Marty Quinn’s proposed ordinance would restrict additional dwelling units in Chicago to just 20% of the city and add costly labor mandates. Marty Quinn, 13th, plans to push a decoy ordinance on Sept. 25 that severely limits where additional dwelling units can be built, requires apprentice labor and boosts aldermen’s power. On Sept. 25, the Chicago City Council is expected to finally vote on the ordinance from Ald. Bennett Lawson, 44th, that would allow homeowners across the city to apply to build additional dwelling units.
