Community groups and elected officials representing the Upper East Side filed a lawsuit targeting DDG’s 32-story luxury condo tower rising at 180 E. 88th St. The suit against the developers and two city agencies contends that the project’s height and configuration were achieved by exploiting a quirk in the zoning code.

“The loophole being abused here is just an example of what residents have endured from overdevelopment in our city,” City Councilman Ben Kallos, who is a party to the suit, said in a statement released Friday.

DDG broke ground on the project in April 2015, but a year later ran into trouble after community groups complained about an unusual aspect of the site’s zoning: The developer had carved out a separate, 4-foot by 22-foot lot along East 88th Street that allowed it to alter the building to a more advantageous shape.
