Chicago Department of Housing Comm. Marisa Novara makes a presentation on a state-enabled tax incentive during a committee meeting on Tuesday.

Aldermen voted overwhelmingly on Tuesday to override their colleague by approving a tax break for a new 300-unit apartment complex planned near the Cumberland CTA Blue Line station that the local alderman, Ald. Anthony Napolitano (41), has staunchly opposed. The development will be a test case in Chicago for the new tax sweetener, which was signed into state law last year in an attempt to incentivize the construction of more affordable homes.
