The vote on Thursday means the proposal will move on to the full City of Chicago Council for consideration. Last week, the city's Landmarks Commission approved the deal, which includes a left-field jumbotron and right-field sign.
The signs are central to the Cubs' proposal because, according to team officials, revenue from them could bankroll the $500 million renovation plan-- $300 of which is earmarked for the actual Wrigley Field, and $200 million for a nearby hotel and park. Right now Wrigley Field is the only ballpark without big outfield signs.
