Negotiations between the Chicago Cubs and neighborhood rooftop owners came to a standstill on Tuesday just days after team ownership spoke optimistically about the deal but at the same time a source says "disrespecting" the rooftop association.

At the Cubs Convention on Saturday, the team said there was positive momentum toward a deal on a $300 million renovation of Wrigley Field. But owner Tom Ricketts compared the situation with the rooftops to a "neighbor watching your television through your window." Later, business president Crane Kenney said of the rooftop owners, "They basically want to delay the project unless there is an accommodation made."

A source familiar with the rooftop association called those comments "not overly helpful" as they went into meetings this week. Any momentum toward an agreement now appears stalled and the rooftop owners have filed a defamation lawsuit against sports consultant Marc Ganis for comments he made last January. The Cubs have been named as a respondent in that lawsuit.

"We have worked hard to reach a resolution with our rooftop partners which would have helped preserve their views, including reducing the number, size and location of signs," Cubs spokesman Julian Green said in a statement. "Unfortunately, they opted [Tuesday] to reject the proposal and file this lawsuit. Since our approvals last year, we have been anxious to get the Wrigley Field renovation started. [Tuesday's] action will certainly force additional delays to our project."

The Cubs and rooftop owners still can't agree on the size and location of a new video scoreboard to be installed in left field for the 2015 season as well as signage to be placed in right field. The ongoing battle has delayed the renovation project of Wrigley Field which was scheduled to begin after last season.
